10. Fits and Clearances

Where applicable, the manual contains cross-references to the Fits and Clearances sectionas indicated by (REF. NO. XXX, Table XXX). The fits and clearances are provided inimperial values.

11. Special Tool Service Bulletins

Special Tool Service Bulletins provide instructions for modifying special tools to a laterconfiguration.

12. Safety

A. This Overhaul Manual describes processes that may require the use of chemicals,solvents, paints or other commercially available materials.

B. Material Safety Data Sheets (MSDS) containing information about Trade Name, SafetyHazards, Health Hazards, Reactivity, Spill or Leak Procedures, Special ProtectionInformation, Special Precautions and Transportation and Labelling are available from themanufacturer. Read these MSDS sheets before you use the consumable materials.

C. Before using any of the consumable materials, be aware of all handling, storage anddisposal precautions recommended by the manufacturer or supplier. Failure to complywith manufacturer’s or supplier’s recommendations may result in injury or disease.

13. General Precautions

A. Dust caps used to protect open-ended tubes against contamination must always beinstalled over ends of tubes and not inside as plugs. flow will be blocked if tubes areinstalled with plugs inadvertently left inside. Caps must be installed to prevent dust, dirt,lockwire, nuts, washers and other foreign matter from entering the engine. If anyparts are dropped, the disassembly or assembly procedure must stop until the droppedarticle(s) are located and removed, even if it takes a considerable amount of timeand labor. Suitable caps, plugs and other sealing devices must be used to protect allopenings as soon as they are exposed. Make sure that all parts are clean prior toassembly or installation.

B. Critical areas of engine parts, such as compressor and turbine disks, must be protectedagainst scratches and nicks during assembly. Make sure that tool surfaces contactingthese areas are covered with protective material to prevent damaging engine parts.

C. When tubes, lines and engine parts are removed, examine each component for indicationsof scoring, burning, and other undesirable conditions.

D. Hammers used to remove or assemble engine parts must be faced with either plastic orrawhide.

E. If adhesive tape has been used, it must be removed and the part thoroughly cleaned ofall tape residue with solvent, prior to the part being subjected to elevated temperaturesduring engine run. Avoid leaving tape residue as test results indicate that all tapesare capable of causing surface corrosion and/or reducing tensile strength when exposedto temperature increases.





F. To exclude foreign materials from the compressor section, the air inlet case and screenshould be covered with a plastic (or similar) sheet, cut to size, and retained withadhesive tape.

G. Do not reuse lockwire, lockwashers, tabwashers or cotterpins. Only use lockwire andcotterpins as specified.

H. Replace all gaskets, packings and rubber parts at reassembly. Make sure that newnon-metallic parts to be installed (such as an oil seal) show no sign of deterioration.All preformed packings must be lubricated at installation (Ref. Subpara. 15. following).

I. When installing hydraulic or pneumatic lines, whether solid tubes or flexible hoses, makesure lines engage onto respective adaptors without tension or load. Alignment must beobtained by adjusting the position of the adaptors.

14. Replacement Parts

A. When replacing gaskets, preformed packings and other rubber parts, make sure that thecorrect parts are used by checking part numbers.

B. Prior to installation of new parts, check for signs of deterioration or damage due tostorage. Before mating components, make sure surfaces have no burrs or sharpedges liable to damage preformed packings.

C. In areas where packing retainers are used, install retainers with concave face towardspreformed packing.

15. Lubrication of Preformed Packings

A. Procedure

CAUTION: APPLICATION OF LUBRICANT AND CORRECT ASSEMBLY WILL PREVENTDAMAGE TO PACKINGS WHICH COULD CAUSE ENGINE MALFUNCTION.

NOTE: New preformed packings of O-ring type must be coated with a thin film of theappropriate lubricant prior to installation.

(1) Apply the appropriate lubricant to the packing, packing retainer and elbowconnector thread.

(2) Engine Fuel and/or Air System - use Calibrating Fluid (PWC03-002).

(3) Engine Oil System - use Engine Lubricating Oil .

16. Bearings

A. Do not intermix bearing components. Do not use a soft metal drift for bearing installation,as metal chips flaking off the soft material may lead to bearing damage. Use onlyapproved tools.

B. Bearings with puller grooves must be installed with grooves facing the correct directionfor future removal. Inner and outer races must be checked to make sure that matingnumbers correspond. Installation details are given in Table 1, and Figure 3.





TABLE 1, Installation of Main Bearings

Bearing(Ref. Fig. 3) Installation Details

1 Puller groove on split inner race to rear. ’X’marks on races aligned with No. 1 tie rodposition. Serial numbers of outer race and ballcage to point to the rear of the engine.

2 Serial number of inner race to point to thefront of the engine and aligned with masterspline in stubshaft. Serial number of outer raceto point to the front of the engine (Ref. NOTE).

3 Serial numbers of inner and outer races topoint to the front of the engine, and alignedwith ’X’ mark on shaft (Ref. NOTE).

4 Puller groove on front-half inner race to pointto the front of the engine. ’X’ marks on innerraces and shaft aligned. Serial number ofouter race and ball cage to point to the front ofthe engine.

Propeller Shaft Thrust and Roller Bearings Serial numbers to point to the front of theengine.

NOTE: During disassembly, if the inner race of a serviceable No. 2 or No. 3 bearing(s) is foundto have its serial number toward the rear of engine then it can be re-installed with itsserial number toward the front of the engine (propeller).

C. To assemble inner races of bearings and other associated parts on their mating shafts,expand them by controlled heating. Heat inner race of demountable bearings, andcomplete bearing assembly of non-demountable bearings, to a temperature of 122° to148 °C (250° to 300 °F).

D. The use of freezing/dry ice is not permitted for the installation of bearing races.

E. No ball or roller bearing shall be removed from its sealed package until required foractual assembly. Bearings should be removed from the sealed package and immersedin mineral oil heated between 150° and 170 °F to dissolve the preservative. Clean thebearings with petroleum solvent at 25 to 35 psi, and immerse in approved oil.

F. Bearings should be handled as little as possible, and never with bare hands. Alwayswear clean, lint-free gloves. Maintain a thin film of oil on bearing parts. Bearingsshould be repackaged after removal from the engine so that there is no ‘‘metal-to-metal’’contact/motion between the bearing components. Split races and ball cages to bekept in separate bags or restrict movement of components by ty-wraps.

G. Clean and protect bearing assembly tooling from contamination.





H. If one bearing supporting a shaft or rotor assembly fails, all other bearings on the sameshaft or rotor must be replaced. A bearing failure in this context, is when one bearingsupporting a shaft or rotor fails causing extra loading to be applied to remaining bearing(s)of same shaft or rotor. Examples of such a failure would be: Broken bearing cage,rolling elements or raceways jamming.

I. No bearing repairs are permitted other than the repairs contained in P&WC approvedmanuals or the Anti-Friction Bearing Visual Inspection Standard P/N 3039731.

J. Scratches, scoring, nicks, dents, etc., are reasons to declare a bearing unserviceableand replaceable, but does not constitute a bearing failure.

17. Antigalling and Antiseize Materials

A. To avoid contamination and blocked passages, antigalling and antiseize compounds areapplied as a thin, even coat, and excess material completely removed.

B. Do not use antigalling or antiseize material on silver-plated bolts.

C. The following antigalling and antiseize materials are recommended for the specificapplications stated.

D. Dow Corning 77 Part Assembly Paste, formerly Molykote M77, lubricant (Ref. ConsumableMaterials List, P/N 3043340) should be used on all loose-fit splined accessory drives,such as the starter-generator gearshaft, which are external to the engine and have noother means of lubrication. If 77 Assembly Paste is not available, high temperaturegrease may be used as an alternative.

E. Antiseize compound should be used for lubricating turbine shaft splines, threads andother components which are not subjected to elevated operating temperatures.

F. Molybdenum disulfide is supplied in paste form, Gn Metal Assembly Paste, and inpowder form, antiseize compound. Mix with preservative oil (Ref. PWA Overhaul StandardPractices Manual).

G. Penetrating oil may be used to facilitate disassembly of power turbine and other hotsection parts.

18. Accessories

A. When test instructions call for removal of lockwire to adjust screws on FCU or propellergovernor, each screw must be lockwired after completion of test.

B. Before and after installation of any accessory components serviced per appropriateaccessories Overhaul Manual, make sure all lockwire and lead seals (whereapplicable) are intact. Replace damaged or broken lockwire, after retorquing per applicableaccessories overhaul instructions. In instances where lead seals and/or associatedlockwire is damaged or broken, return affected accessory for recalibration per applicablemanual (Ref. Introduction).

C. Immediately before installation, remove shipping plugs, covers, etc., and, whereapplicable, drain preservation fluid and flush component with calibration fluid(PWC03-002), unless otherwise stated.

19. Hardware Identification

A. Identification methods of nuts and bolts used on P&WC engines are described in theP&WA Overhaul Standard Practices Manual.

B. Correct engine assembly procedures require that particular attention be paid to materialspecifications for nuts and bolts used in the hot section of engine. In areas where partsmust be manufactured from materials that are resistant to high operatingtemperatures, special heat-resistant alloys are employed. During reassembly of enginecomponents, it is imperative that properly identified, serviceable parts are installed at theiroriginal locations.

C. Segregate all hot section nuts and bolts as they are removed, place in containers andlabel to indicate location. The adoption of this practice will make it possible for serviceactivities to avoid assembly of standard parts, having similar physical appearance, inlocations which require high heat-resistant parts. When new parts are required, makesure that you select the correct nuts and bolts per the Illustrated Parts Catalog forassembly of engine.

20. Elbow Installation

A. Procedure (Ref. Fig. 4)

(1) Lubricate new preformed packing (4), backup ring (3) and thread of elbow (1) (Ref.Para. 15.).

(2) Install jam nut (2), backup ring (3) and preformed packing (4) on elbow (1),pressing backup ring into counterbore of jam nut.

(3) Turn jam nut (2) down elbow (1) until preformed packing (4) is seated in non-threadedgroove of elbow, DETAIL 1.

(4) Turn jam nut (2) outward until preformed packing (4) is pushed firmly against firstlower thread of elbow (1), DETAIL 2.

(5) Install elbow (1) into boss (5), allowing jam nut (2) to turn with elbow untilpreformed packing (4) contacts boss mating face (this point will be recognized byincrease in resistance), DETAIL 3.

(6) Hold jam nut (2) stationary and turn elbow (1) into boss a further 1-1/2 turns.

NOTE: The elbow may be further turned inward a maximum of one turn to facilitatealignment. Should the jam nut tighten on the elbow before the elbow isfully installed in the boss, the nut may be allowed to turn with the elbow.

(7) With elbow (1) correctly aligned, torque jam nut (2) to recommended value.

(8) Make sure metal-to-metal contact exists between jam nut (2) and boss (5), and thatthere is no protrusion of preformed packing (4) or backup ring (3), DETAIL 4.





(9) Lockwire jam nut (2) if required.

21. Torque Tightening

A. Torque Values

Torque values given in this manual are either standard or specific values for the sizeand thread configuration of the item concerned (nut, bolt, screw, etc.). Standard valuesare given in the appropriate Chapter/Section/Unit for the part being assembled.Specific torque values are provided by P&WC engineering department for particularlocations on the engine. These torque values are listed in the Table of Fits and Clearancesin the appropriate Chapter/Section/Unit. All torque limits have been established withthe understanding that standard temperatures prevail. When implementing standardtorque procedures, as outlined in the P&WA Overhaul Standard Practices Manual, thesupplementary procedures following must be included.

B. Slotted Locknuts

Effective locking of steel slotted locknuts to bolts or studs on engine assembly requiresfull engagement of all locknut threads. As the chamfered portion of the locknut IDdoes not exert a force on the bolts or studs, it is not necessary for bolt or stud to beflush with, or protrude from, the top face of the locknut.

C. Silver-plated Bolts

Thread lubricant is not required for silver-plated bolts.

D. Power Torque Wrench

The retaining nut for the propeller shaft bearings and the power turbines are to beremoved and installed with a power torque wrench and appropriate adapters, refer tothe applicable Table of Special Tools.

The power torque wrench employes a high-ratio geartrain operated by a handcrank(supplied with the tool) or a pneumatic ratchet drive tool. A 3/4-inch square drive bar (alsosupplied with the tools) transmits the output torque of the geartrain to the socketwrench of the nut being turned. Two 1/2-inch diameter pins on each special adaptertransmit the counteractive load. Input and output shafts of the wrench rotate in the samedirection.

It must be emphasized that, when using a countertorque adapter, the direction of theinput drive is opposite to that required on the nut being turned, i.e. when tightening aright-hand thread nut using socket and adapter, the input drive must be turnedcounter-clockwise; when loosening, the reverse rotation applies.

E. Procedure

(1) To tighten nut using the power torque wrench and appropriate countertorqueadapter:

(a) Install socket wrench on nut.

(b) Install appropriate countertorque adapter on part being assembled.

NOTE: Observe instructions marked on adapter denoting direction of rotationrequired when torquing and untorquing.

(c) Install power torque wrench on adapter and engage both pins.

(d) Insert 3/4-inch output drive bar into wrench output shaft and turn until barengages socket wrench.

(e) Turn ratchet (located on front face of power wrench) in same direction as thatrequired to turn output drive shaft.

(f) Insert input drive source (handle or power-operated wrench) in input shaft andturn in direction required for output shaft.

(g) Continue turning until torque indicator reaches required reading on scale.

NOTE: Since the torque indicator is calibrated in pounds-feet, theappropriate conversion must be made when torquing to valuesspecified in pounds-inches.

(h) To remove power wrench, reverse direction of rotation of input drive untilindicator returns to zero (green band); this removes the holding pressure on thewrench, allowing it to be withdrawn from the adapter.

(i) Remove power wrench, adapter and socket wrench.

(2) To untorque, repeat (1), but reverse rotational direction of ratchet and input shaft.

22. Locking Devices

A. General

Locking devices used throughout this manual are described in the P&WA OverhaulStandard Practices Manual. Further supplementary information is provided below.

B. Keywashers

Two types of keywashers are in general use throughout the engine: tab and cup. Do notuse keywashers more than once. All locking tabs of a tab-type keywasher must bebent, unless otherwise specified, to prevent possible reuse, and at least one key must

be bent to meet the requirements specified in P&WA Overhaul Standard PracticesManual. Sharp-edges tools must not be used for bending tabs as this practice can leadto material failure and detachment of the defective tabs, resulting in possible damageor failure of the engine.

Except when special crimping tools are provided, cup-type keywashers must bedeformed with a suitable spherical-ended tool, preferably of the squeeze type. Wherethis type of tool is not practicable, a spherical-ended drift or punch should be used instead.Crimping should be performed in at least two places on the OD or ID (as applicable)of the washer, but if the bolt head or nut has specially machined locking slots or scallops,all such slots must be used.

C. Lockwire

The type of wire used on the original assembly of the engine complies with SpecificationAMS5687 and, unless otherwise specified, is 0.025 inch diameter heat- andcorrosion-resistant steel wire, MS9226-03.

To avoid mutilation of the twisted section of the lockwire, grip the end of the lockwirewith pliers at a point that will not be kinked or nicked.

Use extreme care to prevent lockwire ends from falling into the engine.

Leave at least three complete turns of wire after the loop and remove ends by cutting offcleanly. Do not pull or twist the ends off with pliers, as the strength of the material atlockwire holes is marginal.

23. Marking of Parts

Use the methods described in the PWA Overhaul Standard Practices Manual to mark engineparts, weldments or assemblies, unless otherwise specified in the Chapter/Section/Unit.

24. Identification of Metal Particles

A. Metal particles found in the fuel and/or oil filters may be deposits of steel, tin, aluminum,magnesium, silver, titanium, bronze or cadmium. In some instances the type of metalcan be determined by the color and hardness of the pieces. However, when the particlescannot be positively identified by visual inspection and knowledge of the exactcharacter of the metal is desired as an aid to troubleshooting, simple tests as detailed inthe appropriate section or subsection of the P&WA Overhaul Standard PracticesManual must be carried out.

B. Certain corrosion-resistant and stainless steels used in the engine are nonmagnetic.Should particles having an appearance of steel texture prove to be nonmagnetic whenchecked with a magnet, continue with the remaining tests for non-ferrous particles. If theparticles remain unidentified after these tests, it should be assumed that they arenonmagnetic steel.





25. Welding

A. The following procedures apply to components that are dispositioned for repair bywelding and are removed from the engine. Weld repair of components still installed on anengine is not permitted. Welding must be carried out only by qualified personnel.

WARNING: AN ARGON REGULATOR SHOULD ALWAYS BE USED FOR INERT GASWELDING. IF, HOWEVER, AN OXYGEN REGULATOR IS USED, IT MUSTNOT BE REINSTALLED ON AN OXYGEN CYLINDER. INERT GAS USED INWELDING PROCEDURES IS NOT FREE FROM OIL AND, AS A RESULT,THE POSSIBILITY EXISTS OF AN EXPLOSION BEING CAUSED BY THEPRESENCE OF OIL WITH OXYGEN. USE SAFE WELDING PRACTICES,ADEQUATE VENTILATION, AND PROTECTIVE EQUIPMENT. DO NOTWELD IN CONFINED AREAS WITHOUT EXHAUST VENTILATION.

B. Recommended welding procedure used in this manual, Tungsten Inert Gas (TIG), isdescribed in the P&WA Overhaul Standard Practices Manual and should be used forrepairs of cracks or effecting patch repairs on engine parts. Although argon or helium gasmay be used in inert gas welding, argon is recommended by Pratt & Whitney CanadaCorp. because its greater density reduces its rate of diffusion with the atmosphere.

C. Because a high percentage of steel parts used on the engine are fabricated from highchromium content corrosion-resistant steels that are characteristized by their susceptibilityto air hardening, repair of cracks by fusion welding is a special problem. The hightemperatures at which fusion weld repairs are made and the subsequent air cooling ofthe part, or parts, from these temperatures usually results in an increase in materialhardness and a loss in ductility. Parts on which fusion weld repairs have been madehave a tendency to crack because the steel structure becomes unstable, brittle and highlystressed. The structure of the material can be improved by reheating the parts andcontrolling the cooling rate.

D. Components which are not highly stressed may be repaired by fusion welding. It ispossible to partially restore the original properties of such welded componentsthrough the use of local heat treatment. Localized heat may be applied by neutral flameof an oxy-acetylene torch. Extend the stress relief one inch minimum beyond thewelded area. After the desired heat has been applied on the component for the properlength of time, reduce temperature gradually.

26. Riveting

Use the methods described in the PWA Overhaul Standard Practices Manual to rivet parts,unless otherwise specified in the Chapter/Section/Unit.

27. Borescope

A. The borescope is an optical device which is used for visual inspection of the hot-sectionareas without disassembling the engine.

B. The borescope camera is used for recording an inspection of hot-section areas on filmor print.

C. Reference should be made to the Maintenance Manual P/N 3013242, Chapter 72-00-00for detailed operating instructions of borescope equipment.





28. Carbon Dioxide - Solid (Dry Ice)

WARNING: WEAR LEATHER GLOVES AND SAFETY GLASSES WHEN YOU HANDLEDRY ICE. THE TEMPERATURE OF SOLID CARBON DIOXIDE (DRY ICE) ISAPPROXIMATELY -79°C (-110°F) WHICH CAN CAUSE FROST BURNS.

Solid carbon dioxide (dry ice) is applied to some tight-fitting parts during assembly ordisassembly. Dry ice chills the part, shrinking it, to facilitate assembly or removal of the part.

29. Tubes and Hoses

Alignment of externally routed tubes and hoses must be achieved by adjusting connectorsand fittings to avoid bending, twisting and kinking of the tube or hose. External lines aresecured only after tubes and hoses are suitably routed.

30. Pressure Flushing

A. Engine components undergoing overhaul are subjected to various overhaul processesthat expose the parts to possible contamination by foreign materials used in theprocess. Entrapment of these materials in the oil system can cause premature wearand/or damage of components. Such materials may consist of machining swarf, blastingmedia and cleaning chemicals. In order to make sure that foreign materials areremoved from all components before final assembly, it is highly recommended to pressureflush all passages where foreign materials can be trapped. This procedure is ageneral instruction on how a pressure flush should be done to be effective.

B. The first and most important step in preventing contamination with process materials isto prevent them from entering the components during processing. Masking the openingscorrectly is the best prevention. Even when masking is done correctly it is necessaryto flush the part.

C. In order to ensure the parts are clean, pressure flushing is the second step. The flushingmust be done prior to coating processing to prevent entrapment of materials byover-spray coating that may enter the passages. Pressure flushing is the introduction ofclean filtered solvent (PWC11-027) in solid liquid form (not aerated) under pressure,into cored passages of components. The higher the volume of liquid introduced, the moreeffective the flushing will be. It is necessary to have a sealed inlet where the solvent isintroduced to the part. The solvent should exit the part through all related openings withvelocity indicative of the inlet pressure. The minimum and maximum pressure mayvary depending on the part but generally should not be below 50 psi. Complex housingswith multiple passages must be flushed simultaneously to prevent re-contaminationfrom one passage to the other. Where simultaneous flushing is not possible and passagesare independent of each other, flushed passages must be masked off before the nextpassage is flushed in sequence. Many parts have passages with large inlet bores andsmall exit holes. In these cases it is recommended to flush from small to large holesinitially and then reverse flush from large to small. The solvent must flow for a period offive minutes minimum in either direction.

D. In certain cases where complex geometry can retain material even after flushing, aborescope inspection of passages is required to verify the effectiveness of theflushing procedure. This requirement will be specified for the affected parts.





E. P&WC Facility Planning manual 3040878 supplies the basic schematic for theconstruction of a recommended pressure flushing rig. The outlet manifold of the rig musthave at least 10 quick connect lines capable of simultaneous delivery while maintainingthe minimum pressure.

F. Parts requiring flushing following the rework cycle are as follows for the PT6A seriesengines.
