REASSEMBLY
Assemble the countershaft and driveshaft in the reverse order of disassembly. Pay attention to the following
points:
NOTE:
* Rotate the bearings by hand to inspect for smooth rotation. Replace the bearings if there is anything
unusual.
* Before installing the gears, apply engine oil to the driveshaft and countershaft.

NOTE:
When reassembling the transmission, attention must be given to the locations and positions of washers and
snap rings. The cross sectional view shows the correct position of the gears, washers and snap rings.
(3-47)
• When installing a new snap ring, pay attention to its direction.
Fit it to the side where the thrust is as shown in the illustration.

* Never reuse a snap ring. After a snap ring has been removed from a shaft, it should be dis-
carded and a new snap ring must be installed.
* When installing a new snap ring, do not expand the end gap larger than required to slip the
snap ring over the shaft.
* After installing a snap ring, make sure that it is completely seated in its groove and securely
fitted.
