Fourth and Second Clutch Functional Air Check

1. For the purposes of this test, attach the driven sprocket support assembly (609) and the second clutch housing thrust washer (611) onto the second clutch housing assembly (617).





2. Apply 138 kPa (20 psi) to the feed holes marked 2 and 4, and listen for the second and fourth clutches to apply.

IMPORTANT: Air pressure that exceeds recommend intensity may damage the seals or cause the seals to roll.

3. Hold the pressure for five seconds. If the clutches do not apply and hold, then disassemble the driven sprocket support components. Inspect all of the seals and clutches for proper assembly. When finished, repeat the functional check.





4. When the clutches apply and hold correctly, remove the driven sprocket support assembly (609) and the second clutch housing thrust washer (611) from the second clutch housing assembly (617).
