removinG And rePlAcinG hub Assembly in Flywheel
If the flywheel bearings or pulley are damaged a new flywheel hub assembly will need to be installed .
Pull the left pillow block off the bearings after flywheel is removed from bike . Remove the three screws
(M6 x 16) from the left side of the flywheel with a 4mm hex wrench . These screws hold the hub assem-
bly to the flywheel . Once hub assembly is removed apply medium strength Loctite to the three M6 x 16
screws . Insert the new hub assembly in the flywheel and install the three M6 x 16 screws with Loctite .
Firmly tighten screws and place left pillow block back on bearings . Flywheel assembly is now ready to
be installed on the bike .
Installation
Place the pillow block nuts back in the frame . The flanged nuts need to be inserted on the left side and
the nuts with no flange need to be inserted on the right side (Note: These cannot be reversed since a
flanged nut on the right side will rub on the drive belt) . Rotate the pillow blocks so the tops of both are
facing up and are parallel with each other (if one or both of the pillow blocks rotates during the install
and is inserted into the cutaway upside down the flywheel will sit cockeyed and/or up too high) . Care-
fully lift the flywheel assembly back into the frame and lower the pillow blocks into the cutaways in
the frame . Once the flywheel sits securely in the frame, apply Loctite to the pillow block screws . Insert
the screws through the pillow blocks, start tightening by hand and then firmly tighten with a 5mm hex
wrench . Reinstall the fender assembly, drive belt and belt
cover . Ride the bike to test .
