Tube holders are easily connected to the fuel tank by screws. Using screws is much more secure
than using glue to attach the holders to the fuel tank.
The larger insert decreases the
fuel tank volume by 2cc, and is
recommended for use when the
fuel filter is used.
The smaller insert decreases the
fuel tank volume by 1cc.
1CC FUEL TANK INSERT
2CC FUEL TANK INSERT
The fuel tank has the larger fuel volume and includes OPTIONAL tank inserts for decreasing
the volume of the tank. Using the inserts allows you to adjust the volume of fuel inside the
tank; this works in conjunction with variables such as fuel filter capacity and/or length of
fuel line to ensure you have the legal fuel volume limit for racing.

Tighten the clutch nut using
HUDY tool #107581
Hold the flywheel using
HUDY Flywheel Tool #182015
These bearings must still
be regularly serviced and
replaced when worn out.
Note the orientation of the clutch
shoes. The short side of spring must
be in the groove of the flywheel nut.
It is very important that your XB8 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.
