7. Measure clearance between retaining plate and snap ring using
feeler gauge. If not within allowable limit, select proper retaining
plate. Refer to “Parts Information” for retaining plate selection.
8. Check operation of reverse clutch.
High Clutch INFOID:0000000004305521
COMPONENTS
DISASSEMBLY 1. Check operation of high clutch.
a. Apply compressed air into the oil hole (A) of input shaft assem- bly (high clutch drum) at the location as shown.
CAUTION:
Block the oil hole (A) on the opposite side with lint-free
cloth (B).
b. Check to see that retaining plate moves to snap ring.
c. If retaining plate does not contact snap ring: • High clutch piston seal might be damaged.Specified clearance
Standard and allowable limit: Refer to AT-375, " Clutches and Brakes " .

INSPECTION
High Clutch Snap Ring 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 lo cations and find the average.
• Inspect all drive plates.
• Replace if the thickness is below the allowable limit.
High Clutch Spring Retainer Assembly Check length (L) of springs retainer assembly. Replace if damaged,
deformed or worn.
CAUTION:
Do not remove return springs (A) from spring retainers (B).
High Clutch Piston and Cancel Cover Check for deformation or damage. Replace if necessary.
Input Shaft Assembly (High Clutch Drum) Check for deformation or damage. Replace if necessary.
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).
