4. Air check reverse clutch assembly to ensure proper operation of seals and clutch assembly. Apply 20 psi (1.41 kg/cm² ) of compressed air to specified location to check component operation. See Fig 1 . If clutch assembly does not operate properly, check component installation.
5. Install 2nd roller clutch assembly into roller clutch cam. Install 2nd roller clutch onto reverse clutch housing with flat side of roller clutch cam facing down toward housing. Rotate roller clutch during assembly to properly engage rollers.
NOTE: When installing roller clutch assembly, Installer (J-41235) is designed to press roller clutch assembly to a specified depth. If 2nd roller clutch is installed too far down onto inner race, roller clutch may not operate properly.
6. Ensure roller clutch operates properly. While holding reverse clutch housing, roller clutch cam should only rotate clockwise. See Fig 2 . Install NEW 2nd roller clutch retainer onto 2nd roller clutch assembly. Using Installer (J-41235), press retainer and roller clutch assembly into place on reverse clutch housing and roller clutch inner race.
7. Install reverse clutch and 2nd roller clutch assembly into transaxle case. See Figure . Tangs on reverse clutch housing spline to tangs on reaction carrier sun gear and shell assembly.
