Lubricating Front Chain

Front chain is automatically lubricated by engine Chain oiling is adjustable and occasional readju^ment^ may^be needed to meet lubrication requirements of varied operating conditions.

IpeS hole cover from very close inspection of chain. If cham appea raises the least doubt as to its getting ample lubrication, add one or two more .002" washers under head of chain oiler adjusting screw. A well lubricated chain not only has an oily surface, but is also clean and free of discoloration. If chain has a brownish hue, and rusty appearance at side and center plates, it is under-lubricated even though the surface may be oily.

Since the quantity of oil involved is very small, the opening through which oil bleeds to chain is regulated by adjusting screw to a very small orifice. Sediment and gummy matter accumulated in oil supply deposits in and around this orifice and gradually decreases the oil supplied to chain. In other words, a chain that has been lubricating perfectly the first 2000 miles may run short of oil the second 2000 miles. Therefore, even though inspection indicates chain is amply lubricated, it is advisable at intervals of approximately 2000 miles, to loosen the chain oiler adjusting screw, and back it up about two turns. Operate this way a few miles and then turn screw back down moderately tight against its adjusting washers. This procedure flushes away accumulated sediment and restores oil orifice to its original size.

The same result can be accomplished if compressed air is available, by completely removing screw and washers, flushing opening with gasoline and blowing out. When this procedure is followed, care must be taken not to lose any of the thin washers tinder screw head, otherwise when screw is installed, it will not have the same adjustment as it did before being removed.

Following the above recommendations will go a long way toward eliminating chain failure.

If it is definitely determined that chain is getting an excessive amount of oil, remove one or more thin washers from under head of chain oiler adjusting screw. It is advisable to remove only one washer at a time and inspect chain again after motorcycle has been run approximately another hundred miles to determine whether or not further adjustment is needed.
