Check the side gears, pinions, pinion thrust washers, and cross shaft for wear or damage. If there is excessive wear, cracks, nicks, groovesor galling, replace the parts.

Inspect the carbon surfaces. After cleaning with a solvent, the carbon surface should appear a course weave fabric with flat spots on thepeaks of the weave.

If the surface is smooth, either from wear or from the weave filled with debris, replace the entire disc pack.

Measure the thickness of the carbon friction discs.

If the measurements is below the limit value, replace the disc.

Inspect the splined friction discs. If they have grooves or are polished, replace the entire disc pack. Small scratches on them are O.K.

Measurement for R.H. pocket

Measure the R.H. pocket with the pinion shaft installed as shown in illustration.

Measurement for L.H. pocket

Measure the L.H. pocket with the pinion shaft installed according to the following formula as shown in illustration.

L.H. POCKET = A + B - C

Measurement for the side gear sub height.

As shown in illustration, install the clutch disc, side gear, preload spring and spring plate, and then adjust the clearance of the preload spring by applying the pressure at both sides till it is 32mm as shown in illustration. At this time, measure the height of side gear sub at RH, LH sides by measuringthe length of "D"
