Primary Fluid
Its me again asking questions about my "new" bike - 82 FLH. I have been reading thru my manual and have yet to see anything about adding fluid to the primary. I want to remove the derby cover and check for fluid. If it low, what do I put in there? I may just go buy a new primary gasket and pull the whole thing off so I can get a better look. As always, your guidance is appreciated. I assume I fill with some type of fluid up to just below the derby cover level?

IF it is stock you do nothing...it gets oil from the oil pump when it is running.

Thanks for the feedback. Since I have no clue if its stock, the fun begins.

Look and see if you have hoses running from the oil pump to the primary

ive had the primary off my 82 FLH ..yes it gets oil mist from the breather on your gear case via a hose to the back of your inner primary case.... on further inspection the line was blocked with gunk at the inner primary fitting. I was scratching my head why when i undid the primary drain bolt nothing came out.

Well one thing I know for sure is that the final drive chain is getting its fair share of oil. So much in fact, that after a long ride, there will be oil splattered all over the underside of the chain guard and splattered lightly on my back wheel. real pain in the ***. The guy I bought the bike from told me that it does this and that a mechanic had told him there was nothing that could be done about it. I highly doubt that but hopefully I'll find the root of that issue one day.

And as you can see, there is an adjustment screw for your rear chain oiler, so if you beleive it is getting too much oil, you can make an adjustment. However, there will always besome oil coming off the chain
