Band Servo Piston Assembly

Band Servo Piston Assembly
DISASSEMBLY





1. Remove band servo piston bolts using suitable tool.





2. Apply compressed air to oil hole in transaxle case to remove O/D servo piston retainer and band servo piston assembly.

NOTE: Hold band servo piston assembly with a rag or nylon waste.





3. Apply compressed air to oil hole in O/D servo piston retainer to remove O/D servo piston from retainer.

CAUTION: Hold O/D band servo while applying compressed air.





4. Remove D-ring from O/D servo piston.

NOTE: Do not reuse D-ring.





5. Remove O-rings from O/D servo piston retainer.

NOTE: Do not reuse O-ring.





6. Remove band servo piston assembly from servo piston retainer by pushing it forward.





7. Place piston stem end on a wooden block. While pushing servo piston spring retainer down, remove E-ring using suitable tool.





8. Remove O/D servo return spring, band servo thrust washer and band servo piston stem from band servo piston.





9. Remove O-rings from servo piston retainer.





10. Remove D-rings from band servo piston.

INSPECTION
Pistons, Retainers and Piston Stem
^ Check frictional surfaces for abnormal wear or damage.

Return Springs





^ Check for deformation or damage.
^ Measure free length and outer diameter.
Inspection standard: Refer to "Band Servo"
