LC4 rear axle/chain slider - fabricate or buy?
« on: December 08, 2015, 08:51:54 am »
On trying to remove wheel for balancing, spotted my rear axle chain adjuster is cracked through on right side  :crybaby2:
Got the bike recently, and axle nut is way overtightened, suspect this is the reason for the crack.

According to parts listing, axle and left chain adjuster are one unit, and cost R677.56 from KTM  :o

Anyone have a spare one lying around?
Thoughts on getting it machined out of EN18/25? Or am I wasting my time given the KTM price?

What does the opposite side cost, part #41.
I am sure a good engineering shop can get the broken part off the shaft and fit that instead?


Side note... KTM, why overcomplicate a simple part? Both the tensioners should be interchangeable!

Good idea thanks!
Right side tensioner is R151.
Let me take a closer look to see if they can be swopped

The right hand one is not threaded.

I also had the same problem. Had a shop do the thread for me. The rest I made to shape with a saw and a file. Next time don't over tighten it.

Rost offroad also sells. http://rostoffroad.co.za/?product=chain-tensioners

Thanks. Quality looks good and fair price.
If the axle is fine, Rost tensioners look like a good option.

Agreed, 450 bucks is in the same ball park as what an engineering shop my ask to modify in any case.
