20. Inspect the Drive Pulley and the screws that secure it.
* If the Drive Pulley is worn or damaged OR any of the screws have been
sheared off, use the "Replace the Drive Pulley" Procedure for replacement
instructions.
* If one or more screws are currently missing, skip to Step 21.
* If all four screws are present, use an appropriately sized hex wrench to
remove one of the four screws that attach the Drive Pulley.
21. Using a 5mm hex wrench, attach one of the replacement screws and
lock washers provided in the kit. Fully tighten the screw. Once fully tightened,
secure the screw with one of the provided securing nuts using a 10mm wrench.
22. Rotate the Drive Pulley to replace each screw with the provided hardware
(screw and securing nut) one at a time.
Note: The kit contains a replacement Drive Pulley. This part will not be used if
this procedure is performed correctly.
23. Installation is the reverse procedure excluding steps with the Crank Puller.
The Crank Puller is not required for re-assembly.
Note: When replacing the Crank Arm be sure the Right and Left Crank Arms
are oriented inline and opposite each other.
The Crank Nut should be tightened to a torque value of 29-32.5 ft lbs (or 350-
390 in lbs).
