Lube the splines...

[mo8414]

Good question. It should probably be replaced at some point ( when?). My Roadster had one too. Just saw @TURBO200R4 response. He’s no doubt right and could be good for the life of the bike

Think about a spring inside a gun. They can take quite a beating, I doubt this spring will ever need to be replaced.

i had really hard time when I did try to lube the splines last year,
the issue i faced was using the nut method remove and re-install the stud, the nut were not up to the quality( tried buying from 3 different sellers) and kept slipping on me and i started having a lot of issues, i kept ordering nuts to match the stud thread size but they didnt, barely few of them matched and i was somehow able to finish it,

unless I find a reputed stud remover and install kit which will fit the thread size on this differential stud I am not touching that.

M12 x 1.25 lug nut would probably work to seat the stud. Just get one that is not open on the back so it can bottom out on the stud so you can turn it.

I've been laying a bit low. Had some heart scares after getting my Mom through the hospital during the holidays, into rehab, and now finally back home. I just did a heart catheterization two days ago (went OK) and the 3R is just starting to undergo what will be a very slow, I'm sure, to finish 40k mile service. Crazy times, but life is good.
What's up?

Oh man… that’s a lot all at once. I’m really glad to hear the heart cath went okay though — that had to be stressful. And getting your mom through hospital → rehab → back home during the holidays? That’s superhero-level stuff. No wonder you’ve been laying low.

I'm in the middle of greasing my spline. Got to clean up and install the studs tomorrow. I was thinking it may be easier to remove the top drive shaft cover to gain access. Pull the driveshaft out a bit so you can line it up and seat it into the final drive. Then use your left hand to guide the driveshaft spline at the top into the trans since there is a lot more room at the top.

Also to get the drive shaft cover off after removing the bolts. Use ypur fingers to push down real hard on the cover in the area that is closest to the bike. Its kind of a pain but that is the easiest way.

I grease the splines first time at 62000 Km due to unintended major overhaul. Never had any issues or need to do it earlier. I admit it depends a lot on climate a road dirt. The swinging arm is full of cast/ventilation holes like a Swiss cheese so those riding in dusty areas may see a lot of dirt coming in. Not my case, it looks quite clean. But I digress. What I wanted to add is that one may want to condition the rest of the shaft too. Seal caps and circles get rusty too. I sprayed ACF-50 over entire shaft and I will smear some heavy duty vaseline for excavators or similar with a paint brush. Then lube the spline when I put it back together. It very likely it won't touch it again for the next 50000 Km when I will probably check the universal joints and replace bearings if needed.

Good luck with all that. I had OHS two years ago this March 8. All good now. Its amazing the medical tech they have these days.

My solution to make tightening the stud in easier. Lowes has a nice selection of fasteners.

Hopefully all of your health issues get resolved journeyman. Sorry to hear about the recent events.

This didn't work because there is not enough threads for the bolt not to strip at the torque you need to seat the stud so next time in going to use these coupling nuts which should work good. I ended up doing as journeyman suggested, using two nuts tightened against eachother to jam it so it wouldnt move.
