Changing Differential Gear OilNLS00086
1. Drain oil from drain plug and refill with new gear oil.
(For details, refer to FFD-8, "
Changing Differential Gear Oil" and RFD-9, "Changing Differential Gear Oil"
.)
2. Check oil level.
Balancing Wheels (Bonding Weight Type)NLS00087
REMOVAL
1. Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:

Be careful not to scratch the road wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer
unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.Oil grade and Viscosity:
Refer to MA-12, "
RECOMMENDED FLUIDS
AND LUBRICANTS" .
