FIGURE 8

ROCKER SHAFT LOCATION MARK

punch mark determines the quantity of oil delivered ~o the rockers and bearings. Oil flow may be I ncreased or decreased by rotati ng the shaft ina clockwise or anti-clockwise direction as required. It will generally be found that with the shaft slot and punch mark aligned the oil supply is most satisfactory.

Adjust valve clearances to 0·012" (0·305 mm.) inlet and exhaust.

Refit oil feed pipe between cylinder head and camshaft housing.

Replace injectors, using new washers, and connect up injector pipes and leak-off pipes.

Tighten injectors evenly.

Fit rocker cover and joint.

FIGURE 9

ADJUSTING TAPPETS

ADJUSTING VALVE CLEARANCE (Refer Figure 9)

The three throw 120 0 crankshaft makes it necessary to adopt a slightly different sequence for tappet adjustment to the normal accepted procedure for four and six cylinder engines.

To adjust tappets proceed as follows :-

Remove the rubber plug in the inspection hole in the left front side of the transmission housing adaptor plate.

Rotate crankshaft until the T.D.C. line on the flywheel is in the centre of the inspection hole and No.1 piston is on compression stroke (both valves fully closed).

Check and adjust clearances as necessary on Nos. 1, 2, 3 and 5 valves (Figure 9).

Turn cran kshaft one revol ution (360 0 ) and repeat for Nos. 4 and 6 valves. (T.D.C. mark visible through inspection hole).

Replace rubber plug in adaptor plate.

Valve clearances for both inlet and exhaust should be set to 0·010" (0·254 mm.) hot, and 0·012" (0·305 mm.) cold.

C.7

Immerse piston in clean hot oil or water to permit easy entry of the gudgeon pin.

Insert connecting rod between piston bosses. ensuring that piston and connecting rod markings are correctly related.

Insert gudgeon pin in position and fit the second circlip.

Ensure that both circlips are properly located in their respective grooves.

Fit piston ri ngs.

FITTING PISTONS AND CONNECTING RODS (Refer Figures 32 and 33)

Thoroughly clean out cylinder bore and apply a generous coating of clean engine oil.

Lubricate piston.

Locate piston rings so that ring gaps are staggered and evenly spaced.

Fit piston assembly ring. Service Tool P.D.107. to piston, entering it from underside of piston with chamfered edge towards piston crown.

Remove bearing cap, big end bolts and bearing shells. If the old shells are to be re-used, they must not be interchanged.

FIGURE 32 FITTING PISTON TO ENGINE

FIGURE 33 CHECKING PISTON HEIGHT

Check that number on connecting rod is to fuel pump side of engine.

Insert connecting rod and piston into cylinder bore.

Gently press piston through assembly ring into cylinder bore (Figure 32).

Turn crankshaft until appropriate crankpin is at B.D.C.

Fit big end bolts and upper bearing half. ensuring that tongue is correctly located.

Lubt'icate top bearing half and crankpin.

Draw connecting rod into position on crankpin.

Place bottom bearing half in bearing cap.

Lubricate bearing and fit cap to connecting rod. taking care that the position of the connecting rod bolts is not disturbed and that the cap marking coincides with the connecting rod.

Fit new self-locking nuts and evenly tighten to a torque of 70-80 Ibs.jft.

With the crankshaft at T.D.C. the proximity of the piston crown to the cylinder block face should be within zero to - -- 0·005"_ Pre-top pistons should be within -- 0010" to ! 0-004" (Figure 33)_

PROPORTIONAL ENGINE SPEED

This drive is selected by pulling the lever upwards

(see Fig. 2) to engage the internal splines of the

ground P.T.O. driven gear with the splines on the

rear end of the hydraulic pump drive shaft. The

FIG. 4

PROPORTIONAL ENGINE SPEED

P.T.O. shaft is then driven at 18/50 of the engine

r.p.m., a speed at which most P.T.O. driven equip­

ment is designed to operate. It should be noted

that the P.T.O. shaft is coupled behind the hydraulic

FIG. 5

NEUTRAL

pump shaft, the pump is therefore constant running

and continues to operate even when the P.T.O. is

disengaged.

PROPORTIONAL GROUND SPEED

This is engaged by pushing the P.T.O. lever down­

wards towards the ground-thereby shifting the

ground P.T.O. driven gear into mesh with the gear

splined on to the rear axle driving pinion. The P.T.O.

shaft speed is then intimately related to the ground

speed of the tractor and the shaft revolves once for

approx. every 20" (508 mm.) of travel by the rear

wheels. If the tractor is reversed the direction of

rotation will also be reversed and this characteristic

must be remembered as the implement mechanism

may be damaged if driven in reverse.

FIG. 6

PROPORTIONAL GROUND SPEED

LIVE P.T.O.

The De Luxe Tractor is fitted with Dual Clutch and

live P.T.O. The P.T.O. drive from the engine is

controlled by the clutch pedal in the bottom half

of its range. The initial movement of the clutch

disengages the transmission only; additional down­

ward movement disconnects the hydraulic pump

and P.T.O. shaft and transmission. On the Basic

tractor the hydraulic pump and P.T.O. shaft and

transmission are driven directly by the transmission

countershaft, and on the De Luxe tractor by a drive

shaft which passes through hollow countershaft

assembly, and is therefore independent of the

gearbox. (See also Clutch and Transmission

Sections of this Service Manual).
