WHEEL BALANCE
• Carefully check balance before installing the
wheel.
• Mount the tire with the arrow mark facing in the
direction of rotation.
• The wheel balance must be checked when the
tire is remounted.
• For optimum balance, the tire balance mark (light
mass point: a paint dot on the side wall) must be
located next to the valve stem. Remount the tire
if necessary.
Mount the wheel, tire and brake disc assembly on
an inspection stand.
Spin the wheel, allow it to stop, and mark the lowest
(heaviest) part of the wheel with chalk.
Do this 2 or 3 times to verify the heaviest area.
If the wheel is balanced, it will not stop consistently
in the same position.
To balance the wheel, install a new balance weight
on the lightest side of the rim, on the side opposite
the chalk marks. Add just enough weight so the
wheel will no longer stop in the same position when
it is spun.
Do not add more than 60 g to the wheel.

Loosen the brake disc mounting bolts in a crisscross
