Final gear drive assembly housing

[Chris Cochran]

Ok, with my wheel off this thing is greasy dirty, big time. It's difficult to see from this specific picture but there are eight bolts visible. However, there are eleven threaded bolt holes visible. The one at 4 to 5 o'clock and the one at 9 o'clock seem to have a broken off bolt in each hole. The one at 2 o'clock is empty.

I have no plans on dis-assembling it, aside from removing it from the swing arm, but I'm wondering how critical it is with the open bolt hole. I plan to find a bolt to fill it. The factory vent hole is fine.

Please click on the pic for the picture to orient itself correctly.

I can't make much out from this photo. The manual has pretty good info about this maintenance. I posted about doing it just this spring -- https://www.amervoyassoc.org/forum/view ... hp?t=12907. I took some photos of mine, but not sure they show what you seem to be asking.

The last picture in your posting (VERY clean drive assembly, by the way) does show the "2 o'clock" empty bolt hole as mine has. So, I deduce that this is a normal condition.

I was going to pull the thing off today but tomorrow will have better weather, so I'll spray the absolute snot out of it to clean it.

Please read the manual. It has an entire chapter dedicated to the final drive. In Chapter 10, you'll see that these holes are to jack the final drive apart. I didn't go there ... thank god.

Yes, it was a PITA the clean -- took a lot of paper towels and Q-tips. Easier once off the bike and in hand.

Ok, got the final drive off, drained, and eventually cleaned decent enough. Splines lubed. Got the swing arm off, pulled the bearings and greased them. Got the drive shaft off (my pin did not go flying either) and lubed.

It's all put back together as it was this morning when I started with one exception: Discovered that the left side, upper shock bolt is stripped for the last quarter inch or so. When I undid the acorn nut earlier, I thought that it came off really easy. That's because it was only on by perhaps one thread.

I have a tap and die set that I'll use in the morning to rethread the smooth part.

Things I noticed throughout this sub-project: The outside of the final drive was really nasty greasy as is the wheel. When the wheel was off, the visible part of the assembly, as seen in my earlier pic was also really greasy. Interestingly, while all of the splines, wherever they were, looked to be in perfect shape, there was almost zero lubrication/grease on them.

When I drained the final drive fluid, it was gloopy, thick, almost like a sludge, and not much of it. However, the gears that I could see through the large opening where you pour in new fluid, looked very good.

Today was 88 degrees and about 2 o'clock the sun starts creeping into the garage, so that's a natural time to quit for the day. The next few days will be in the 90s so it'll be good to leave the wheel/tire and new tire outside to warm up.

I want to give a shout out to NAILS for his pictorial on this stuff. It helped me. Thanks!!

Chris,I am glad you did not lose the retaining pin
