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).
Important: Air pressure that exceeds recommended intensity may damage the seals
or cause the seals to roll.
Apply 138 kPa (20 psi) to the feed holes marked 2 and
4, and listen for the second and fourth clutches to apply.
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.
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).
