I may need a new clutch

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Not yet, mine were worn badly and it was still working, not great but worked. I took the opportunity while I had it apart to change it out but I could have gotten away with it for a bit longer but figured with my luck it would fail a month later and I would be taking it all back apart again. I got 80K out of the first one so I hope I can get near the same again with all new parts. I lubed the heck out of it and hope that will extend the life some. Wierd that only one plate wears on the shaft.

conundrum is the word for this seemingly common issue. takes some KMs to do the fretting damage and its a expensive PITA to fix. Don't think when the time comes for me i could replace the clutch with the fretting, it would drive me nuts. i probably would try myself or send it to a good Ural dealer. anyway its a weak link in the Ural drive line among several. with IMZ working to update the new bikes would like to see this addressed. :cheers:

Maybe after 50,000KM I will replace the shaft...

+1 on the Staburags paste for BMW dry clutch splines. Does Ural apply anything to the splines during factory assembly, or recommend anything at designated service intervals?

doubt if its done at the factory, and haven't seen any maintence schedule on the output shaft spline. IOM, a real shame the issue hasent been addressed. better shaft metallurgy and different clutch spline teeth. the issue seems to be unique to Ural with a few exceptions,(dry clutch) rather than wet. :cheers:

Moly and clutch splines has come up a lot lately...from another post post...
I have used the thinnest coating of Jet Lube MP-50 on my trans splines and that seems to be keeping them alive.

It is a high temp, high moly paste grease.
I clean the hell out of the splines with solvent and let it dry thoroughly.
Then I use a flux brush and paint on the thinnest coating possible.
I'm talking a large pea-sized amount painted into and onto the splines and shaft.
It should look like matte black chrome when you are done.
No globs or excess to fling onto the plates.

Whenever I have any of the slip joint or wheel splines exposed for repairs, I do the same.
Again a very thin coat on the splines. For wheel and 2wd shaft splines I add Mobile 1 red synthetic grease to keep water and grit out.

I just installed the third clutch and the transmission splines look good, but I'm probably burning mine up more from off-road wheel slippage, so less stop-start/downshifting wear and tear than a high mile street bike.

But I attract a lot of crud in all my splines from mud and dunking in dirty water; the MP-50 definitely protects against the corrosion and wear.

Just IMHO, I don't think anything is going to stop splines being indented, thru sheer pressure, short of not riding the bike. :(

As I said earlier Moto Guzzis have exactly the same problem, only difference is the gearbox splined boss is a separate part, so not the whole shaft has to be replaced.
However the driveshaft has 4 splined joints, 2 either side of the UJ and 2 at the FD pinion, and they all get hammered. Altho they can still last a long time, albeit with a fair amount of slop.

I could be wrong, but I think Jason or Nik told me the factory uses moly on the clutch splines for a couple of years now.

Well, I replaced the clutch and it went together well.....
Now the Engine is racing like the throttle is wide open. That was the underlying problem, but the clutch was worn out.
I am looking at all of the connections but Fuel Injection is very mysterious to me.
I have made an appointment for repair.... May 15th

There must be too much air getting in then. A common occurrence is a cable ferrule getting hooked up on the 1-into-2 throttle cable splitter, i.e. it's not fully home in its hole. Unfortunately the splitter is in an awkward place under the tank so difficult to see and fix.

thanks Van, wonder if and when the factory might have taken the advice to add lube at assembly. like to know if my 2016GU maybe got a application of moly. wishful thinking! :cheers:
