Install the D-section ring in the groove on the outside surface of the piston with its round side out. Install another D-section ring to the front clutch retainer.
Apply automatic transaxle fluid to the outside surface of the D-section rings. Then push the piston into front clutch retainer by hand.
Install the return spring and spring retainer.
Compress the return spring with the special tool (0945324000) and install the snap ring.
Install the four clutch reaction plates and three clutch discs. Prior to installation, apply automatic transaxle fluid to them.
When new clutch discs are used, they should be immersed in automatic transaxle fluid a minimum of two hours prior to installation.
After installing the snap ring, check to see if there is a 0.70.9 mm (0.028-0.035 in.) clearance between the snap ring and the clutch reaction plate.
To check clearance, hold the entire circumference of the clutch reaction plate down with 50N (11 lb.) force. If clearance is out of specification, adjust the clearance by selecting the proper snap ring.
