Maintenance and Repair
❑
Pay attention to section “Cleaning and Inspection Guidelines,”
beginning on page 6-6 to ensure a thorough installation.
❑
Make sure the needle bearing is in place (over the male end of
the sliding gear) before sliding the tail shaft assembly into
position.
❑
Rotate the sliding gear shaft and manually shift the gearshift to
check for proper operation - spins and slides freely.
❑
Refer to the previous sections to rebuild the top portion (upper
housing assembly) of the gearbox.
Sliding Gear Shaft Assembly
See Figure 6-17: “Lower Housing Assembly.”
Notes: If only the sliding shaft assembly is removed, shift the
gearshift mechanism to engage the sliding gear (PUMP position). The
sliding tail shaft assembly and the shift cylinder assembly need not be
removed.
