Gearbox without low range or hydraulic reverser

– Replace any defective components.

– Check correct operation of all components.

– Refit the primary shaft with its taper bearing.

– Make sure that the 5th gear synchro hub is installed the right way round.

– Refit the rear intermediate shaft.

– Insert the washer (2) on the shaft on completion of the rebuild.

– Refit the flange (1) and tighten its fastenings at a torque of 8,5 ± 1,5 daN·m.

Note: Pull on the shaft while turning it alternately clockwise and anticlockwise to properly seat the bearings.

– Replace the shims and the circlip.

Adjustment - Rear intermediate shaft bearings Adjustment is made to the rear intermediate shaft of the primary gear train. Adjustment must be carried out before the secondary gear train is refitted.

– This must be between 1,3 and 3,3 daN for the 16 tooth pinion and between 1,15 and 2,8 daN for the19 tooth pinion.

– Wrap a cord around the rear intermediate shaft.

– If the force required falls outside these limits, repeat the adjustment operations and change the shims, then repeat the check:

– Using a n° 77 0138 800 8 spring balance, pull on the cord until the shaft starts to rotate.

– The primary shaft must be held stationary.

– Measure the corresponding force "F".

– Increase the thickness of the shims (31) if the strength is too low.

– Reduce the thickness of the shims (31) if the force is too high.

– Continue until the force obtained is correct.

– Calculate the corrected apex distance "R", (see table).

– Using the comparator, measure the gap "M" between the apex distance measured "D" and the theoretical apex distance "T" with the reference shim No.77 0138 851 6:

D T

M=T–D The thickness of the shims to use "G" corresponds to the following calculations: Shim thickness "G" = Distance calculated "R" – Theoretical distance "T" + Gap measured "M"

323msm1e

Fig. 18

G = (R – T) + M Example: Corrected distance "R" = 66,70 mm.

Theoretical distance "T" = 66,60 mm.

Gap measured "M" = 0,60 mm.

Shim thickness "G": G = (66,70 – 66,60) + 0,60 = 0,70 mm.

In this example, shim thickness "G" to be used is 0,70 mm.

Note: The available shim thicknesses are: 0,1 mm ; 0,15 mm ; 0,2 mm ; 0,5 mm ; 1 mm.

– Record the shim setting for the secondary shaft for use during final assembly.

– Re-dismantle the shaft and dual taper bearing.

The setting is attained when the mean value is obtained on the dial gauge.

– Repeat the same operation on the synchro unit for the 3rd and 4th gear ratios.

– Adjustment of the 5th gear ratio and the ranges is achieved using a set of feeler gauges positioned between the sliding gear and the fork. The same value of backlash must be obtained on each side.

Important: Check that there is backlash between the fork and the sliding gear to avoid friction and premature wear in the syncho bushes.

Replacement of rear axle casing

– Always change the O-ring seal (37).

– If the values specified on the bossing (rear right) (56) of the new casing are different, change the drive gear timing.

– Apply lubricant to the differential mechanism and turn it using a rea axle shaft.

Note: If new washers are being used, the mechanism should turn with a small amount of resistance.

If changing the rear axle casing, reusing the crown wheel and pinion, proceed as follows:

– Refer to the intervention data sheet on the part: 02 30 Mechanical reducer.

Preliminary operations – Position the tractor on flat and level ground.

– Chock the wheels.

– Drain the rear axle.

– Place the tractor on stands.

– Remove the rear wheels.

– Remove the cab: – Refer to the part: 12 Cab and driving seat.

– Remove the linkage cover: – Refer to the part: 06 Rear lift.

Take precautions against unexpected movement of the tractor. When the rear axle is supported on axle stands, never start the tractor. Risk of the tractor moving if there is any action on the brakes (service or hand brake). If you must start the engine, the front axle must also be supported on stands or the shaft to the front axle must be decoupled.

– Measure thickness (D) of the piston: Thickness 22.

77 0138 837 7

– Calculate G = C + D + E – Calculate Y = F – G – Calculate A = Y – 3 Note: 3 mm corresponds to a fixed value of clearance given by the manufacturer.

Example: G = 11,34 + 22 + 23,80 = 57,14 Y = 64 – 57,14 = 6,86 A = 6,86 – 3 = 3,86 The shim thickness to be used in our example is thus 3,86 mm. Tolerance : 0 ; + 0,20.

Setting the piston stroke The insertion of shims "B" limits the piston stroke to reduce to a minimum the compression of the flexible assembly (17) in the declutched position.

– Measure thickness "H" of the piston: Example 31 mm.

– Using tool No.77 0138 837 7, pressurize the friction block by applying a load of 250 daN. Measure the dimension "E": Example 23,80 mm.

– Fit spacer n° 77 0138 837 9 by inserting it in the groove in the bell.

– Using an electronic dial gauge measure dimension "L" between the upper face of the spacer and the bottom of the bore of the bell: Example "L" = 70,96 mm. Subtract the value of the overlap of the spacer i.e. 10 mm. Dimension "L" becomes 60,96 mm.

Calculate the shim thickness The shim thickness must ensure an end float of 0,02 to 0,10 mm at the taper bearings:

X A

Formula to be used:X = B – A – 0,05 (0,05 mm is an average set value for the end float).
