Step 48 Clutch & Clutchbell Alignment
Over the next few steps the upper and lower frames will
be joined. The frames have the necessary slots to allow for
precise alignment between the clutch and the clutchbell.
The goal is to have the clutch sit parallel and centered in
the clutchbell. It is best to sight the bottom edge of the
clutch with the aluminum clutchbell in both fore-aft and
left-right directions to ensure remains parallel when all
the fasteners have been tightened. It may be necessary to
further loosen the frame fasteners.
Now that the gear mesh has been set, go back and remove all the
upper frame screws one screw at a time, apply L242 Blue thread-
lock and tighten in place. These include the M3x8 frame screws,
M3x30 bellcrank screws and the front hex spacer screws.

One at a time, remove each of the M3x8 and M3x12 socket cap screws, apply L242 Blue
threadlock and tighten in place. After completion, you should still be able to thread the paper
strip through the gears. If not, repeat this procedure.

and the clutchbell gear. Press the clutch bell
towards the main gear and tighten up the

when the paper strip will pass between the
gears without ripping or damaging the paper
strip, but no looser.
