Periodic M aintenance Procedures
Drive Chain Lubrication
•
If a special lubricant is not available, a heavy oil such as
SAE 90 is preferred to a lighter oil because it will stay on
the chain longer and provide better lubrication.
•
If the chain appears especially dirty, clean it before lubri-
cation.
CAUTION
The O -rings between the side plates seal in the lu-
bricant between the pin and the bushing. To avoid
damaging the O-rings and resultant loss of lubri-
cant, observe the following rules.
Use only kerosene or diesel oil for cleaning an O
-ring drive chain. Any other cleaning solution such
as gasoline or trichloroethylene will cause deterio-
ration and swelling of the O-ring. Immediately blow
the chain dry with compressed air after cleaning.
Complete cleaning and drying the chain within 10
minutes.
•
Apply oil to the sides of the rollers so that oil will penetrate
to the r ollers and bushings. Apply the oil to the O-rings so
that the O-rings will be coated with oil.
•
Wipe off any excess oil.

Brakes
Brake Pad Wear Inspection
•
Remove the brake pads (see Brakes chapter).
•
Check the lining thickness [A] of the pads in each caliper.
If the lining thickness of either pad is less than the service
limit [B], replace both pads in the caliper as a set.
Pad Lining Thickness
Standard: Front 4.5 mm (0.18 in.)
Rear 5 mm (0.20 in.)
Service Limit: 1 mm (0.04 in.)
Rear Brake Light Switch Inspection/Adjustment
•
Turn on the ignition switch.
•
Check the operation of the rear brake light switch by de-
pressing the brake pedal. The brake light should go on
after about 10 mm (0.39 in.) of the pedal travel [A].
