I haven't done this for 2 years and I'm sure it's time to do it again... Change my final drive oil. Especially since I put in straight 90W the last time and now I've got Mobile 75-90.

I remember the procedure was pretty simple: put the bike on the center stand, remove the bolt on the left side of the rear wheel, drain out the fluid (giving the rear wheel a few spins to get it all out), then put the bolt back on and fill with a rubber tube/funnel combo, spinning the wheel backwards with each dollop until it's full.

The thing is, I also remember the bolt being made of rather soft aluminum and being advised to use a new one every time I did this. I also remember buying a few extra the first time I did it, but the thing about only having done it once in the past 2 years is that it's who-knows-where in my garage.

I went to BikeBandit to buy a few more (this time, of course, I'll keep better track of them...), but I can't find it on the final drive schematics for the VN750. And I don't remember the "proper" term for it either.

Any help? I'd like to drop the BB order in now along with some other stuff for Spring Cleaning. Did the bolt tightening, oil/filter change, spark plug check and air filter maintenance today, and would like to do brake fluid, fork oil, final drive fluid and air-in-shocks check next weekend.

Here`s the schematic from BB.

The big filler plug with the 27 mm head, #92066 on the diagram, is on the parts list as:
Plug, Oil Filter Cap, M....867273.....(630207-001)

The little filler grubscrew with the 6 mm Allen head, located at 2 O`clock on the circumference of the final drive is not on the diagram,
UNLESS it is #92002, with no line indicating where it goes on the unit.
It is listed as... Bolt....856237....(620608-001)

Does this help?

Thanks OlHoss, I think that is it!

"Oil Filter Cap Plug"... Totally didn't think that would refer to final drive oil, but I guess why not given where this schematic is diagramming?

Is it true though that I need to get a new one every time I remove it, just because it's made of aluminum? Are there any other plugs I should get extras of, just in case (like the crankcase/engine oil plug)?

NO, Just don't over tighten it. I've owned over 10 different bikes and never had to replace either plug and never had any leaks.

OK thanks, that makes sense.

The "aluminum is too soft to risk it" argument must be from people rounding the bolt head.
