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.

do you need to replace the trans spline or can it be cleaned up. :?:

as bad as those are wouldn't they have to be sheared off to make it lurch?

I think it was starting to fail and it was telling me it was time for a change.

I tend to agree, that wouldn't slip. They'd have to be broken off.

PS: however there's enough play to produce a lurching type behaviour, possibly. :?:

Good point, curious if new clutch plates will cure the issue

I'm glad you identified the problem and that it's an easy fix.

Fretting caused by the rear clutch disc appears more severe than the front... at least as far as the gearbox splines are concerned...

Wonder if it’s possible one of the discs would get cockeyed just enough to where the clutch wouldn’t lock up as it should on full release?

Regardless... that’s a new one on me... up til now all the issues I’m aware of both discs caused the same amount of wear on the splined shaft...

Pay attention and you’ll learn something new every day...

I had the same failure on mine. The splines were almost gone and the tranny shaft was badly damaged to the point I had to change it out. Yours is still OK and I would run it for now and just change the clutch plates out. They wore out rather quickly it seems, mine made it to about 80K klicks before it started acting up but by then the damage was complete. You caught it early enough to save the tranny shaft which will save you a bunch of money & frustration. :)

Those notches worn into the tranny shaft are not a concern?
