Adjust engine position to achieve
proper gear mesh
Use appropriate shims to achieve
proper clutchbell endplay
Note the orientation of the
clutch shoes. The short side of
spring must be in the groove of
the flywheel nut.

FUEL TANK & ENGINE
It is very important that your XB808 has properly-adjusted
gear mesh. Adjust the gear mesh so there is adequate (or
slightly larger) space between the spur gear and clutchbell
teeth. Adjust the gear mesh by sliding the engine mounts in
the slots of the chassis. You should be able to rock one gear
back and forth slightly while holding the other one firmly. Be
sure to check the gear mesh all the way around the spur gear.
Tighten the screws once the engine alignment and gear mesh
are correct, and then re-check the gear mesh to ensure the
engine mounts did not move.

Please note that the engine is not parallel with the chassis centerline, so that the
clutchbell engages the spur gear at a slight angle. This is correct and will not have any
effect on handling, performance, or lifespan of any parts.

NOTE ORIENTATION
Not using these shims may
cause that the flywheel pins will
press out after some time.
Although the XB808 clutch
bearings are oversized and have
a longer lifespan than regular-sized
ball-bearings, the bearings must still
be regularly serviced and replaced
when worn out.
