WHEELPINIONCLUTCH
13. Place the wheel pinion onto the output shaft. It is
symmetrical and can be put on either way.
14. Install the internally tabbed thrust washer onto the
output shaft making sure that the tab enters the
keyway.
15. Slip the spring onto the end of the output shaft and
secure with the special retaining clip. Again, make
sure that the center tab ts properly into the keyway
to prevent rotation of the clip (Fig. 173).
16. Slip the wheel, the original number of spacers, and
the wheel cover onto the shoulder bolt and secure to
the pivot arm using the nylon locknut.
17. Grease with No. 2 lithium-based grease. Use a
hand grease gun to avoid excess pressure that may
prevent the friction parts from working. As a rule, use
two pumps to ensure that you do not over-grease.
Be sure to grease after every 25 hours of use for
maximum service life.
