CAUTION
Over-greasing will damage seals.

Pack the steering head bearings with fresh grease at 50,000 miles.
Oil Applications

All control connections and parts as indicated in the SERVICE AND MAINTENANCE CHART (Page 23) should be oiled regularly, particularly after washing motorcycle or driving in wet weather.
Hydro-Glide Fork

The Hydra-Glide fork requires very little maintenance or attention. It requires no greasing. If fork does not appear to be working properly, or

an appreciable amount of oil leakage should develop, attention should be given by an authorized Harley-Davidson dealer.
Incorrect recoil action will result if there is insufficient oil in either side of the fork. To check the amount, completely drain the oil and then pour back into each side 6-1/2 to 7 ounces of Harley-Davidson Hydraulic Fork Oil. Oil drained from the fork may be used again provided it does not appear to be contaminated by water or other foreign matter. Add only enough fresh oil to provide the required amount.

If fork should at any time become submerged in water, drain and refill immediately.
In an emergency, when Harley-Davidson Hydraulic Fork Oil is not available, use the lightest automobile engine oil obtainable. Do not use shock-absorber fluid. If engine oil is used, however, drain and replace with Hydraulic Fork Oil as soon

as possible. The consistency of engine oil varies with temperature changes, and stiff recoil action and a rough ride will result at lower temperatures. Temperature changes have little effect on the recommended oil.

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
