2. Refill with new engine oil. Engine oil specificat ion and viscosity:
Refer to MA-10, "
Fluids and Lubricants".

 The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
 Always use oil level gauge to determine the proper amount of engine oil in engine.

WHEELS (BONDING WEIGHT TYPE)
WHEELS (BONDING WEIG HT TYPE) : AdjustmentINFOID:0000000006394852
BALANCING WHEELS (BONDING WEIGHT TYPE)
Preparation Before Adjustment
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
 Be careful not to scratch th e road wheel during removal.
 After removing double-faced adhesive tape, wi pe clean traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
If a tire balance machine has adhesion balance weight m ode 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 t hat should be used. Select the outer balance weight
with a value closest to the calculated value above and in stall to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
 Never install the inner balance weight be fore installing the outer balance weight.
 Before installing the balance weight, always to clean the mating surface of the road wheel.
