FREE PLAY
6. Lubricate the chains with 80W-90W gear oil.
7. Remove the ratchet pawl (43) and compression
spring (44). Apply multipurpose NLGI Grade
2 grease (such a Mobilgrease
®
HP or Amoco
Permalub) to all working surfaces. Replace the
spring and pawl.
8. Assemble the #40 chain (70).
Note: Install the clip of each connecting link so that
the closed end of the clip faces the direction of
chain travel, as shown in the Exploded View.
9. Loosen, but do not remove, the four nuts (41)
that secure the motor. Push the motor away from
the #40 sprocket (70) to put tension on the chain.
Tighten the nuts (41) to 8 ft-lb (10.8 Nm).
10. Assemble in reverse order.
11. Plug the puller in and turn the puller ON. Listen for
the clicking noise of the anti-reversing mechanism
(ratchet pawl and compression spring). If you do not
hear this clicking noise, inspect and repair the puller.
Do not operate puller if the anti-reverse mechanism is
not working.
Failure to observe this warning could result in severe
injury or death.
Inspecting the Commutator Brushes
(every 40 hours)
1. Remove two brush caps (121). Remove two brushes
(116).
2. Measure the brushes. Replace both brushes if either
brush is less than 3/8" long.
