Disassembly

Caution

identify the position of each removed part.

Organize the parts in their respective groups (i.E., Drive or driven) so that they can be reinstalled in their original positions.

Countershaft

Disassemble the countershaft as shown in the transmission construction. Refer to “transmission construction” .

Pay attention to the following points:

remove the 6th drive gear snap ring (1) from its groove and slide it towards the 3rd/4th drive gears (2).

Special tool : 09900–06104 (snap ring remover
(open type))

Driveshaft

Disassembly the driveshaft as shown in the transmission construction. Refer to “transmission construction” .

Assembly

Note

when reassembling the transmission gears, 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, bushings, washers and snap rings. Refer to “transmission construction” .

Caution

never reuse a snap ring. After a snap ring has been removed from the shaft, it should be discarded 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 the groove and securely fitted.

Note

rotate the bearing by hand to inspect if there is any abnormal noise and for smooth rotation. Replace the bearing if there is anything unusual.
Before installing the gears, apply engine oil to the driveshaft and countershaft.
Before installing the oil seal, apply grease to the oil seal lip.
