alternating between each side. Continue until the Crank Belt (700-

their mid-point.

19. Using a 15 mm wrench, attach the Securing Nuts for the Eye Bolt 

on both sides of the machine.

20. Installation is the reverse procedure. 

Note:

 Be sure when attaching the Crank Arm that all three pieces 

(Crank Arm, Crank Cover, and Connector Arm) are properly aligned 

before installing ANY hardware. The Crank Cover may have rotated 

during the Crank Arm removal.

21. Final Inspection
Inspect your machine to ensure that all hardware is tight and compo-

nents are properly assembled.

Do not use until the machine has been fully assembled 

and inspected for correct performance in accordance 

with the Owner’s Manual.
