Yesterday, I had to replace the whole sprag clutch with a brand new KTM unit &, unfortunately, the SKF spring fix was completely shot; bits of it all over the place in there (nothing left that would be measurable).
I used another spring initially from a different company while waiting for the SKF to arrive; don't remember the name but still have this one intact.
- 1.52mm section diameter
- 56 to 57mm OD (it was installed for a few days so it may be stretched a bit)
Looks like the spring fix didn't last long since the excentric bearings slots were badly scorned initially ...thus grabbing & tearing up the new SKF oil seal spring.
Hope this helps!
