14 Transmission Tear-Down
Disassembly
6. Use a 5mm allen wrench to remove the allen plug to
gain access to the roll pin that holds the shift fork in
place for the differential lock.
7. Use an appropriate punch and hammer to drive the
roll pin towards the front. Be sure that the pin is
being driven straight forward, and not down into the
case.
8. Pull the shaft out along with the spring, spacer and
fork. Replace damaged parts as required.
9. Reassemble the shaft and case using a new o-ring.
Be sure the new o-ring is lubricated and that the lever
is oriented downward. Install the roll pin from the
plug opening. Once installed be sure the roll pin
does not interfere with the case as it rotates during
operation.
10. Lift out the intermediate gear assembly.
Disassemble and examine the components for any
signs of abnormal wear or damage. Note also the
orientation of the bushing flats in the upper case and
notice that there is a slight bevel to the large gear
that faces the center of the transaxle.
