FORWARD AND DIRECT CLUTCH ASSEMBLY DISASSEMBLE^ TOOLS REQUIRED
- J 25024-A Servo Piston/Clutch Spring Compressor
- J 28585 Snap Ring Remover
- J 45186 Forward and Direct Clutch Spring Compressor
1. Remove input shaft O-ring seal from forward and direct clutch and input shaft assembly.
2. Remove forward clutch housing thrust bearing and forward clutch housing thrust bearing race.
3. Using Snap Ring Remover J28585, remove retaining ring (550) from forward clutch backing plate.
4. Remove following components from forward clutch:
^ Backing plate (551)
^ Fiber plates (552)
^ Steel plates (553)
5. Perform clutch plate inspection:
Composition Plates
Dry the plates and inspect plates for the following conditions:
^ Pitting
^ Flaking
^ Wear
^ Glazing
^ Cracking
^ Charring
^ Chips or metal particles embedded in lining
Replace a composition plate which shows any of these conditions.
Steel Plates
IMPORTANT: If clutch shows evidence of extreme heat or burning, replace springs.
Wipe plates dry and check plates for heat discoloration. If surfaces are smooth, even if color smear is indicated, the plate can be reused. If plate is discolored with heat spots or if surface is scuffed, replace plate.
Causes of Burned Clutch Plates
The following conditions can result in a burned clutch plate:
^ Incorrect usage of clutch plates
^ Engine coolant in transaxle fluid
^ A cracked clutch piston
^ Damaged or missing seals
^ Low line pressure
^ Valve conditions
- Valve body face is not flat
- Porosity between channels
- Checkballs are misplaced
^ Teflon@ seal rings are worn or damaged
