Do I really need to do this? Damn, it looks like a lot of work. 93, 135 miles, runs like a top, clutch feels fine and it's quiet. No record of it EVER having been done. Some one tell it's a waste of time.

[Tim (Midland Section)]

Isn't a waste of time. There are two splines to be done. IMHO the most important is the easiest. The drive shaft as it's under greater torque loads.
Nearly 70K on my bike, did them both @ 55K when I did the clutch. Prob do the shaft again when I retire.

Yes it is a major PIA and yes it needs to be done, supposed to be done every 40k.

I can't imagine the bike has gone that far and not had it done at least once. But who knows, even so, it would be due again by now.

Ten years ago my shop bill for that was $600....unless you enjoy pulling transmissions yourself, then it's only $10 worth of Moly.

Isn't there a way to lube the splines (input to the trans) without taking the whole bike apart?

[552255]

Yes Tarheel yes!, there is. Its not 'easy' but somewhat less work.

Briefly, you carefully 'slide' the tranny rearward, riding on pins(M8 bolts) about 2 inches +/-, from the engine/housing, thereby providing access to the elusive trans. input spline shaft. The (2)- longer bolts are put into the same place of the lower existing trans. bolts (the ones all around the housing/trans.) creating a sliding support, thereby protecting the clutch pushrod, and maintaining some semblance of alignment.

With a long 'thin' brush, you dab on the magical moly grease, 'working' it into the grooves. You rotate the rear wheel or reardrive while in gear, to coat the spline all the way 'round. A flashlight is needed to see the shaft, etc.

Then carefully push/slide tranny forward and bolt up...its heavy and a floor jack or jury-rigged dolly helps. Can require a bit of wiggling/rotating to get the splines aligned back up.

Bad news: it still requires all necessary detaching of parts which allow the rearward movement of the tranny....that's the real bitch of the deal, and unavoidable. In order of difficulty K1100: exhaust removal, abs/brake unit, footpeg floor plate, centerstand, battery, foot side plates, etc. You can leave rear wheel on...I think...if bike is supported right. I remove to get to the driveshaft splines--may as well do them too.

I've done it twice, figure it a winter project, will take several hours....
best of luck!!

We've done the Airhead splines twice and the K1100 once.

In each case I've never seen any signs of wear, and while they weren't slathered in grease, they were never dry.

Made me wonder why we bothered. But we enjoy our tech days and working on these beasts. And besides, splines lubes have become a ritual.

Now universal joints are another subject that, unfortunately, you can't do much about.

Live well, do good work, enjoy the ride.

[SugarHillCTD]

The work is slightly easier if your bike has ABS I.

It really isn't that difficult, just takes a bit of time.

Couple pictures from my combo spline lube/O ring/friction plate "tech session" on my previous K1100RS. It really all goes back together pretty easily. Read the shop manual and, of course, you know that any problems you encounter can be solved by some of our very tech savvy folks here.

But to be honest, I only did mine because the clutch started slipping.....

It's not that bad with ABS II. Instead of disconnecting and removing the ABS II control unit and having to reconnect and rebleed the brakes, you can just tie it out of the way to the left frame rail.



Sliding the drive train backwards a couple of inches does not give you the opportunity to check the condition of the clutch plate splines nor clean the old grease out of them. I'm as lazy as the next guy but it is worth the effort, to me, to completely remove the transmission.

Not incompetent or incapable, just old and lazy....oh and did I say CHEEP.

But I'll try to make it a winter project as with 93,000+ I'm sure it needs to be done, along with a couple other items.

Did I mention it still runs REALLY good?
