I have a lot of new KTM parts,but this i really dont have: Bearings M30. they were mounted as the main crank bearings in all 560 type engines from 79 to 84 like 350,420 and 495 engines. i could replace them by the new LC 4 crank bearings,but its not original! Anyone has an idea,where to get it? I lost hope to find them,and im searching for over 5 years.... Thanks Dr.2Stroke

I also asked almost every bearing seller in Europe any holes in their stomaches for these bearings. they were made only by Steyr in Austria. strange,isnt it? Maybe it was one of these special patented bearings,which KTM also builts in in the new 2 stroke engines. Maybe any dealers have some in their "old"parts stock .thanks for helping anyway Dr.2stroke

Doc, I got a set of main bearings from Alan Buehner for my 420. They are SKF bearings #NJ 306 ECP/C3. By the way, my piston questions?? Under the forum "400 pistons.
Thanks

Mike, did you set up the roller bearings to the same specs as the originals or did you use another technique? Also, have you had any problems with the SKF roller bearings?

Found some info as I went shopping for Magneto bearings at one point:
Try Consolidated Bearings, they dist FAG/SKF STEYER....
M25 = 25x62x17
L30 = 30x62x16
M20 = 20x52x15

Hope this helps...
