Driveshaft Spline Lube with Grease Needle

[Red Ridin Hood]

The horror story about dry splines made me do it ! !
Remove rear wheel, (see owners manual)
Remove the three chrome 'acorn' nuts on driveshaft tube.
Slide out driveshaft with rear hub.
Put 19mm hex tool in vise, slide on rear hub with axle vertical. (watch vent hole upper inside of hub, for drips)
Compress driveshaft fully against spring in hub. (to open room for grease) using bar type sliding clamp. ( a really big one)
With c-v joint grease needle on grease gun, and slant of needle point away from driveshaft, (not to cut/nick seal),
carefully insert needle between shaft and seal into void created by compressing driveshaft.
Pump it up ! ! Do this in several spots around driveshaft.
Then remove clamp, and push/pull driveshaft to distribute the grease on splines (at least that's the plan) Do not over fill with grease,
it's gotta have some room to move.


schematic notes from other member post about trouble areas

my notes to correct the position of parts for better understanding of compressing shaft to gain a void for grease


Then do the 'Lamonster' driveshaft install: https://www.m109riders.com/forum/inde...pic,830.0.html I tried the 'stab' but no luck. RRH

ps: Put a little grease on U-joint splines too. IF you suspect that hub end of shaft is totally dry, and or damaged, buy a new seal, and pull it apart, or take it to dealer.

An auto parts store should have them. You can also try Sears.

Nice post ,I wish i understood my computer that good to do all that .

I would really recommend using Molybdenum Grease or engine assembly lube. You also should not pack this with grease about a table spoon and a half in around the spline is good. You do not want to bind this and if you put to much in it will blow out the dust seal and you do not want that

Bike has about 9800 miles on it and never looked at the drive line before so I ripped it apart. Whats one more winter fix while the bike is up on the jack. I think it looked good for the miles and had no problems no metal bits and had some moly on it. Cleaned ever thing and put on some engine assembly lube on it. aka moly graphite I would recommended using this on the drive line.

This is a pic of the splines when I opened it not too bad really.

I dont know if theres a trick to it or not but i had one hell of a time getting the drive shaft to line up with the u-joint at the other end of the tube?How did you guys manage that?

[Les7311]

How many miles on your 9 before you started that invasive surgery?

or how many miles recomended to do this............?

I tried and tried when I did mine. I think I could now that I've seen how it all goes together, but I ended up removing the secondary drive and leaving the final drive loose and pulled back some while reinstalling the secondary.

Does anyone have the original pics from this thread.
I want to see what he means by compressing the shaft and how he did it.
Thanks

Honestly, here is how I did it. Remove the rear wheel, which is easy and in the manual. Undo the 3 acorn nuts and just pull the whole final drive out. You will need c-clip pliers which you can get at sears or even harbor freight. You need to gently pull out the dust seal, or just buy a new one. I can get you a part number if you need. After you pull out the seal, there is basically a c-clip that you undo. Once you do that, the drive shaft just pulls out. There is a spring in there as well and you can take that out. I just greased everything up, and just put back together. I put plenty of grease on the splines and gear. Then put the spring in, put the drive shaft in and put your c-clip loosely in. Then, have someone hold the final drive up, and you push on the shaft and just squeeze the pliers and drop the c-clip in. It is done. then you just reinstall. I usually do it by the way of removing the secondary, or you can try and stab it in the swingarm and mate it up. The original poster decided to try and pump in without taking the shaft out. It is easier to just take it out. Hope this helps.

I bought that seal and never did it if anyone is interested.

My mechanic came up with the idea to drill a small hole close to the rear hub (close to the 3 acorn nuts) and thread in a plug, to have the possibility to squeeze some grease in and to avoid to dismantle the assembly.
But then he change his mind, as the material there is aluminium and he did not trust to do it.

So you don't really save much time by using the grease needle. Thanks for your help i might just get a new seal and do it properly then.

Sorry for the delay as I don't have tapatalk on my phone currently and haven't logged on. My thought on it is that I "preferred" to get in there and check the status of the splines. At that point I cleaned out the old grease and put new grease in. The needle can work, but I just don't like to do things half way.

[rynosback]

The seal part number is 09283-30026. I'm putting a add in the MD chapter for it.

How did you remove the old seal? I've tried a small hook tool but to no avail.

Got it out, grease on hub end was liquefied as others have said. Ordered seal and will do the Lamonster approach.

Well you might get answer... Thread is from 2008 and last reply was 2014!

[UVATom]

Make sure you check the bearings. They could be the cause of the seal going bad.
