To drain and refill fork, remove headlamp and headlamp housing, then
remove the hex head cap screw at the top of each fork side. Remove the
drain plug at the lower end of each slider with a 3/16 inch Allen
wrench, and drain the oil into a clean container. Add oil to container,
if necessary, to make up the required amount. Replace the drain plugs
and add 6-1/2 to 7 ounces of oil through the hole in the upper end of
each fork tube. Then install the cap screw and tighten securely.
Filling the fork using only a funnel is a rather slow job because the
filler openings in the fork are small and the filler channel tends to
become air locked. It is recommended that you see your Harley-Davidson
dealer when this service is required, as he has the necessary equipment
to do the job cleanly and quickly.
The adjustable trail Hydra-Glide Fork (special equipment for sidecar
service) does not have a hex head cap screw at the top of each fork
side, but has oil filler plugs at the rear of each fork
side which can be removed with a large screwdriver.
Hydraulic Brake
Every 1000 miles, check fluid level in master cylinder (6, figure 1)
located just ahead of rear brake foot pedal. When removing filler plug,
be sure that all dirt is removed from around filler plug to prevent
entrance into reservoir. Level should be 1/4 inch from top of cover. Use
only HYDRAULIC BRAKE FLUID, which is approved for use in hydraulic brake
systems.
Battery
It is the care given a battery, rather than time and miles of service,
which is most important in determining its life.
Solution
Inspect level of battery solution at least once a week during motorcycle
operation, adding distilled or other approved water as often as
necessary to keep the solution above the plates. If the motorcycle is
not used for an extended period of time, check solution level before
placing in service.
Remove battery cover and take out 6 screw end filler plugs. With a
hydrometer or syringe, add
