INSPECTION
High Clutch Snap Rings and Spring Retainer Assembly
Check for deformation, fatigue or damage. Replace if necessary.
High Clutch Drive Plates

Check facing for burns, cracks or damage. Replace if necessary.

Measure thickness of facing.
CAUTION:

Measure the thickness at 3 locations and find the aver-
age.

Inspect all drive plates.

Replace if the thickness is below the allowable limit.
High Clutch Piston

Make sure that check balls are not fixed.

Apply compressed air to check ball oil hole opposite return spring. Make sure there is no air leakage.

Apply compressed air to oil hole on return spring side to make sure that air leaks past ball.
Seal Ring Clearance

Install new seal rings onto input shaft assembly (high clutch
drum).

Measure clearance between seal ring and ring groove.

If not within allowable limit, replace input shaft assembly (high
clutch drum).Thickness of drive plate
