INTRODUCTION TO PMCS TABLE

a. General. Your PMCS table (Table 2-1)has been provided so you can keep your equip-ment in good operating condition and ready forits primary mission.

b. Warnings and cautions. Always observethe WARNINGS and CAUTIONS appearing inyour PMCS table BEFORE, DURING, andAFTER you operate the equipment. The warn-ings and cautions appear before certain pro-cedures. You must observe these WARNINGSand CAUTIONS to prevent serious injury toyourself and others or prevent your equipmentfrom being damaged.

c. Explanation of table entries.

(1) Item number column. Numbers in thiscolumn are for reference. When completing DAForm 2404, Equipment Inspection and Mainte-nance Worksheet, include the item number forthe check/service indicating a fault. Itemnumbers also appear in the order that youmust do checks and services for the intervalsIisted.

(2) Interval column. This column tells youwhen you must do the procedure in the pro-cedure column. BEFORE procedures must bedone before you operate or use the equipmentfor its intended mission. DURING proceduresmust be done during the time you are operat-ing or using the equipment for its intended mis-sion. AFTER procedures must be done immedi-ately after you have operated or used theequipment.

(3) Item to Check Service column. Thiscolumn provides the Iocation and the item tobe checked

(4) Procedure column. This column givesthe procedure you must do to check or service

the item listed in the Check/Service column toknow if the equipment is ready or available forits intended mission or for operation. You mustdo the procedure at the time stated in the in-terval column.

(5) Not fully mission capable if: column.Information in this column tells you what faultswill keep your equipment from being capable ofperforming its primary mission. If you makecheck and service procedures that show faultslisted in this column, do not operate the equip-ment. Follow standard operating procedures formaintaining the equipment or reporting equip-ment failure.

GENERAL

a. Corrosion. Refer to page 1-2.

Unusable CARC mixtures may beconsidered hazardous waste andmay require disposal in accor-dance with Federal, state, DOD,and DA hazardous waste regula-tions. Consult the installation en-vironmental office for properdisposal guidance. Mixed CARChas a flashpoint of approximately38°F (3°C) due to the incor-poration of solvents and is highlyflammable.

b. Touchup/Spot Painting. Painting at theoperator level is limited to touchup/spot paint-ing. CARC paint that has been opened must beused within 8 hours or it will deterioratebeyond use. Mix only what is needed for im-mediate use. Refer to TM 43-0139.

c. I f YourTroubleshoot

Equipment Fails to Operate.with proper equipment. Report

any deficiencies using the proper forms. SeeDA PAM 738-750.

PMCS PROCEDURES

a. Perform PMCS each day vehicle isoperated. If vehicle is not being operatedregularly, start and run engine for approx-imately 1/2 hour at least once a week. Whileengine is running, exercise crane controls.Perform only the PMCS required for runningengine and checking crane controls.

b. Perform weekly as well as before operations PMCS and check fluid levels if:

(1) You are the assigned operator andhave not ‘operated the item since the lastweekly.

(2) You are operating the item for thefirst time.

c. While you perform PMCS, have“checker” tools with you and keep an eyeout for the following:

(1) Loose bolts. A loose bolt can be dif-ficult to spot without using a wrench.However, you can often identify loose boltsby observing loose or chipped paint aroundbolt head and bare metal or rust at its base.Tighten loose bolts.

(2) Damaged welds. Damaged weldsmay be detected by observing rust or chippedpaint where cracks occur.

(3) Frayed electrical wires and looseconnectors. Check electrical wiring for cracksdue to aging and exposed wires that couldcause an electrical short. Tighten looseclamps and connectors.

Equipment operation is allow-able with minor leakages (classI or 11). Of course, you mustconsider the fluid capacity inthe item/system being checked/inspected. When in doubt, noti-fy unit maintenance personnel,

When operating with class I orclass II leaks, continue to checkfluid levels as required in yourPMCS.

Class Ill leaks should bereported to unit maintenancepersonnel.

NOTE

Fluid leakage classificationsapply only to hull components.

(4) Fluid leakage. Leaks are divided intothree classifications. Compare leak with thefollowing definitions:

Class I Seepage of fluid (as in-dicated by wetness ordiscoloration) not greatenough to form drops.

Class II Leakage of fluid greatenough to form drops butnot enough to causedrops to drip from itembeing checked/inspected.

Class Ill Leakage of fluid greatenough to form drops thatfall from the item beingchecked/inspected.

d. If your equipment does not perform asrequired, refer to troubleshooting proceduresin chapter 3 for possible problems. Reportany malfunctions or failures on the proper DAForm 2404, or refer to DA PAM 738-750.

e. If an assembly must be removed and/ordisassembled in order to perform PMCS, referto the maintenance procedures in chapter 3.

DRIVING ON ROUGH AND HILLY TERRAiN

Go up and down long grades in range 2 or 3(O-15 percent), steep grades in range 1 (15-30 percent). Don’t coast.

Shift transmission to range 1 (low) before go-ing up or down steep grades and when start-ing on a hill.

Don’t hold vehicle on an upgrade by using ac-celerator. The transmission will overheat.

● Brake vehicle to prevent vehi-cle speed from overrunningengine speed. If vehiclespeed overruns engine speed,you will not be able to downshift to a lower range andmay lose control of vehicle.

Steer vehicle in a series of shortturns rather than a long, eventurn when operating in loosesand, dirt, or rocks. This willallow debris to feed out oftrack. If debris accumulates, athrown track or damage tosuspension system may result.

1 Trench Crossing. Reduce speed as vehi-cle approaches edge of trench, thenspeed up when tracks contact far side oftrench. Maximum width of trench thatcan be safely crossed is 7 ft 9 in. (2.36m).

2 Steep Grades. Speed up as vehicleclimbs hill; slow down at crest of hill andwhile going down. Use range 2 or 3 fornormal grades from 0-15% and range 1for steep grades from 15-30%.

Rope is unsafe ifthree broken wires are found inone strand of 6 x 7 rope, sixbroken wires in one strand of 6x 19 rope, or nine broken wiresin one strand of 6 x 37 rope.

Observe wire ropes when winding ontowinches for proper winding; avoid kink-ing wire ropes. Inspect wire ropes forfrayed, damaged, or broken strands, Uselevel wind on tow winch wire rope forproper Iayup.

Observe boom cylinders for smoothnessand ease of operation.

Observe boom drop rate (distance boomdrops when loaded and boom cylindercontrol valve lever is in center position).Boom will gradually drop if left elevatedwith a hanging load. When hydraulic oilis hot from recovery operations, theboom drop rate should not exceed 1/2in. (1.3 cm) per minute with a 10,000lb. (4,536 kg) load; 1 in. (2.5 cm) perminute with a 20,000 lb (9,080 kg) load;or 2 in. (5.1 cm) per minute with a30,000 lb (13,620 kg) load.

Observe boom winch, tow winch, andtraversing brakes for smooth and effi-cient operation. They should not chatteror slip.

Observe all hydraulic lines, hoses, andconnections for oil leaks. Tighten allloose connections after relieving allhydraulic pressure.

HOISTING AND TOW WINCHING LOADRATING CAPACITIES INSTRUCTION PLATE

Hoisting and tow winching load ratingcapacities instruction plate (view C, page2-75) indicates safe operating capacities ofboom in relation to weight of load beinglifted, necessary boom elevation, areas whereboom may be located while supporting load,and whether spade is emplaced or retracted.For maximum capacity, vehicle must be onlevel ground, suspension locked, and loaddirectly under boom tip. White areas on in-struction plate show where boom must bepositioned with different load conditions, Inall cases, boom placement must be keptwithin white areas when hoisting a loadweighing between 15,000 and 30,000 lb(6,810 and 13,620 kg). When hoisting a loadup to 15,000 lb (6,810 kg), operation inshaded area is permissible. Information cover-ing maximum tow winching and hoistingcapacities with spade emplaced (view A,page 2-74) is shown on left hand side ofplate.

GENERAL TOUCHUP AND RECOATING

Appendix G provides and illustrates cleaning andLubricating procedures as to locations, intervals,and proper materials for this vehicle. Any specialLubricating instructions for specific mechanisms orparts are contained in the specific section.

SERVICE INTERVALS–NORMAL

Service intervals specified in appendix G arefor normal operation and where moderatetemperature, humidity, and atmospheric con-ditions prevail.

When touching up damaged areas, the pro-cedure should be as similar to the originalmethod of finishing as possible; a clean sur-face is imperative. Where general disintegra-tion of the surface is evident, or the undersurface is corroded, the coating must bestripped clean from the part. Corrosion mustbe removed or neutralized by mechanical orchemical treatment, or both, and the surfacemetal must be pretreated, primed, and thentopcoated.

3-2 Change 3

TM 9-2350-238-10

SERVICE INTERVALS–UNUSUALCONDITIONS

A lubricant that contains grit,dust, and sand will be anabrasive and cause rapid wearof parts.

Lubricate more frequently to compensate forabnormal or extreme conditions, such as highor low temperature, prolonged periods ofhigh-speed operation, continued operation insand or dust, immersion in water, or exposureto moisture. Any of these operations or condi-tions may quickly destroy protective qualitiesof lubricants. Refer to FM 9-207 for instruc-tions on necessary special preliminary lubrica-tion of vehicle for continued operation belowO°F (–18°C).

Intervals may be extended during inactiveperiods after application of proper lubrication.

MAINTAINING PROPER LUBRICANT LEVELS

Lubricant levels in engine, transmission, aux-iliary drive, final drives, road wheel hubs,traversing drive, boom winch, tow winch, andhydraulic reservoir must be observed closelyand necessary steps taken to replenish inorder to maintain proper levels at all times.

LUBRICATION AFTER FORDING OPERATIONS

After any fording operation in water 12 in-ches (30.5 cm) or over, lubricate ail chassispoints to clean bearings of water or grit, aswell as any other points required, in accord-ance with page 3-61.

Corrosion is greenish “fuzz” that builds up onbattery posts, terminals, and cables. This cor-rosion not only can prevent starting, but willalso eat up cables and connectors, If cor-roded, notify unit maintenance personnel.

DEEP CYCLING

Deep-cycling is a complete discharge of bat-teries. This will lessen battery life and infreezing weather will burst battery case.Avoid running battery down.

BATTERIES IN USE

Make sure unit maintenance personnel checkspecific gravity of each battery cell weeklywhen vehicle is in use.

BATTERIES NOT IN USE

Make sure unit maintenance personnel checkspecific gravity once a month when vehicle isnot in use. Charge batteries when specificgravity drops below 1.225.

UNSERVICEABLE BATTERIES

If batteries fail to respond, notify unitmaintenance personnel.

EXTREME COLD WEATHER MAINTENANCE

a. General. In extreme cold weather,special purpose kits (Chapter 5) should be in-stalled and operated. Maintenance in extremecold is difficult in the field. Cold increasesmaintenance time. At temperatures below–40°F (–40°C), maintenance requires up tofive times the normal amount of time. Barehands stick to cold metal. Fuel in contactwith hands results in super-cooling due toevaporation and hands can become frostbit-ten. Engine oils, except subzero grade, cannotbe poured at temperatures below -40°F( - . 4 0 ° c ) .

b. Fuel System Maintenance. When condi-tions indicate that temperatures are going tobe below –25°F (–32°C), drain, purge, andfill fuel cell and fuel lines with arctic fuel.

NOTE

Draining fuel system must becoordinated with unitmaintenance personnel.

(1) Remove fuel fill cap (1).

(2) Place suitable container under vehi-cle. Fuel cell contains 260 gal. (984 l).

items are properly stowed andsecured.

c . Do . . . . . . Open hull drain valvesand drain accumulated waterafter crossing is completed.

d. Do . . . . . . Check engine oil leveland crankcase for evidence ofwater as soon as possible aftercrossing.

NOTE

Regular grade fuel, DF-2 (NATOF-54), will thicken or partiallysolidify at extreme cold temper-atures. The entire vehicle mustbe placed under cover andwarmed until fuel returns to a li-quid state.

(3) Remove fuel cell drain plugs frombottom of hull and drain fuel.

(4) When fuel cell is drained, installdrain plugs and tighten securely.

TM 9-2350-238-10

EXTREME COLD WEATHER MAINTENANCE–CONTINUED

(5) Fill fuel cell with fuel, grade DF-A(NATO F-56) and install fuel fill cap.

(6) Provide suitable container and drainapproximately one quart of fuel from each ofthe low pressure and high pressure fuel filters(2 and 3). Close drain valves.

(7) prime fuel system. Refer to page3-32.

(8) Use fuel cycle switch (4) and pumpand heater igniter switch (5) for approximate-ly 2 minutes and then idle engine at 1200rpm for 5 minutes to warm up engine.

c. Coolant System Maintenance. Refer toFM 9-207 for instructions on draining andcleaning coolant system and selection, ap-plication and checking of antifreeze comoundsto suit anticipated conditions.

(1) Check and make sure antifreeze incoolant is correct for lowest anticipatedtemperature. When adding water to system,make sure antifreeze protection is maintained.Operate engine to mix coolant.

(2) Operate coolant heater when vehicleis parked, if installed (Chapter 5).

(3) Make sure fan well deck is coveredwhen vehicle is parked to keep out blowingsnow. Check and remove any accumulatedsnow from fan well before starting engine.

d. Battery Maintenance. Refer to FM9-207 for method of correcting specific gravi-ty readings for batteries exposed to extremecold.

(1) Start and run engine for approx-imately 30 minutes at 1200 rpm to chargebatteries immediately after adding water tobatteries so water will combine with batteryacid and not freeze.

(2) Keep batteries fully charged duringextreme cold weather. The colder batteriesbecome the more battery electric power out-put is diminished.

AFTER FORDING MAINTENANCE–CONTINUED

a. Vehicle Maintenance.

(1) Open three hull drain valves anddrain hull. Clean hull and tracks of mud anddebris. Close drain valves after all water isdrained.

(2) Clean all exposed surfaces andtouch up paint on any damaged paintedsurfaces.

(3) Clean and coat unpainted metalparts with CLP lubricant (item 3, appx D).

(4) Check lubricating oil in engine,transmission, auxiliary drive and final drivesfor water leakage. If there is evidence ofwater entering any of these components,drain, flush, and refill with correct lubricant(appx G). Remove and replace engine andtransmission oil filters.

(5) Clean and lubricate all suspensiongrease-lubricated components. Make sure thatgrease is generously forced into each fittingto force out any water present.

(6) Check road wheel and idler wheelhubs for water leakage. Drain and refill hubsif there is any evidence of water in thegrease.

(7) Check batteries to be sure no waterentered through vent caps. This is of specialimportance should vehicle have beensubmerged in salt water.

(8) Remove, disassemble, and dry airfilter bags.

(9) Check electrical connections for cor-rosion, particularly bayonet-type connectors.Dry and clean any wet or corrodedconnections.

b. Armament Maintenance. If the arma-ment has been splashed with water or hasbeen accidentally submerged, precautionsmust be taken as soon as possible to avoiddamage to materiel.

(1) Completely disassemble armament(TM 9-1005-213-10). Clean, dry, andlubricate all exposed unpainted parts as soonas situation permits.

(2) Regardless of temporary measurestaken, notify unit maintenance personnel sothat complete disassembly, cleaning, andlubrication can be accomplished.

UNUSUAL TERRAIN MAINTENANCE

a . M u d .

(1) Clean vehicle thoroughly and dry.

(2) Lubricate vehicle as prescribed in ap-pendix G. Pay particular attention to suspen-sion components. Be sure to force out anydirty lubricant.

(3) Clean power plant reservoir drain inbottom of hull. If drain becomes plugged withmud, pressure may build up in transmissionand cause violent eruption of oil whentransmission oil level dipstick is removed.

(4) Clean tow winch and boom winchwire ropes. Do not coat wire rope with lubri-cant. Lubricants mixed with grit create anabrasive paste that is more damaging to wirerope than the lack of lubricant.

(5) Clean air filter bags daily if/whenoperating in mud. When air filter baskets areremoved, inspect air separators for clogging.If clogged notify unit maintenance personnel.

(10) Drain primary and secondary fuelfilters of any accumulated water.

b. Sand and Dust.

(1) Thoroughly clean and dry vehicle, in-cluding power plant compartment.

(2) Lubricate vehicle as prescribed in ap-pendix G. Be sure to force out any dirtylubricant.

(3) Check for chipped paint. Have unitmaintenance personnel prime and paint anyarea where paint is etched or chipped.

(4) Cover entire vehicle with tarpaulin, ifpossible. If entire vehicle cannot be covered,protect periscopes against etching by wind-blown sand. Also, protect engine compart-ment against entry of sand and dust.

(5) Clean tow winch and boom winchwire ropes. Do not coat rope with lubricant.Lubricants mixed with sand create anabrasive paste that is more damaging to wirerope than the lack of lubricant.

(6) Disassemble and clean machine gunat least once each day. Remove lubricants onexposed and noncritical operating surfaces ofmachine gun and mount. This will preventwindblown sand and dust from sticking to oiland forming an abrasive. Clean and lubricatemachine gun and mount with CLP lubricant(item 3, appx D) immediately upon leavingsandy terrain.

(7) Clean air filter bags daily whenoperating in sand or dust. Extreme conditionsmay require cleaning filter bags more thanonce a day. When air filter baskets areremoved, inspect air separators for clogging.If clogged, notify unit maintenance personnel.
