Installation
1. Apply a thin coat of molybdenum disulfide grease to
the top gear shaft spline.
2. Slowly operate the transmission jack until the front of
transmission is aligned with the rear of the engine.
The slope of the engine and the transmission must be
the same.
3. Align the top gear shaft spline with the clutch driven
plate spline.

5. Apply a force of about 113N (26 Ib) to the tip of the
shift fork in the direction of the transmission to engage
the clutch pressure plate and release bearing.
NOTE: A clicking sound is heard when the release
bearing and the tip of the diaphragm spring engage each
other.
Check to see if they are securely engaged by pushing the
tip of the shift fork toward the engine while applying a
force of about 25 N (5.5 lb). If the shift fork will not move,
then they are securely engaged.
