CENTER SUPPORT ASSEMBLY (CONT'D)
15. Turn the center support over on flat surface,
as shown in Figure 111.
16. Install the sprag lube seal (Fat "O" Ring), as
shown in Figure 111.
Note: There is an installation cone available
as shown in Figure 111, but is not really a
mandatory tool.
17. Lubricate the seals on a new low/reverse clutch
molded piston and install into center support,
as shown in Figure 112.
18. Check for proper sprag rotation, as shown in
Figure 112. Low sprag should freewheel in
counter-clockwise direction while holding the
inner race and lock in clockwise direction.
19. Install the low sprag assembly onto the hub of
the center support, as shown in Figure 112.
Note: Ensure the blind spline on the sprag
inner race is aligned with the corresponding
blind spline on center support hub. Some of
the low sprags come apart with the removal
of snap ring, as shown. Some low sprags
come as a complete assembly and are only
serviced as an assembly.
