the forward clutch assembly, retaining it with oil-solu-
ble grease (Figure 7–22).

assembly. The hub splines engage the transmission
main shaft. The splines on the fourth clutch drive hub
engage the internal splined plates of the fourth clutch.
(3) Rotate the forward clutch assembly one
or two revolutions, while pushing it downward. Make
sure all the fourth clutch internal-splined plates are en-
gaged.

M6-1 x 80 mm guide bolts into the retarder housing
assembly (Figure 7–23). Install the front stator, stator
blades first, aligning the holes in the stator with the
