RM500 Crankshaft problem
Posted: Wed Dec 04, 2019 12:25 pm
Hello All:
I have an 1983 Suzuki RM500D that has a problem. The inner race on the left hand crank bearing is loose on the crankshaft. I need to tie this bearing race down so that it spins with the shaft instead of the crank wheel spinning in the race.
By loose, I mean a slip fit. If the bearing lines up perfect, it pushes on with no effort.
There does not appear to be any wear on crankshaft where the bearing mounts.
I have been offered opinions on how best to accomplish this.
1. Replace the crank wheel. It is obviously too small. ( This is not cheap)
2. Peen up the shaft and push the bearing on. This was considered a short term fix. ( Seems somewhat brutal although i do trust the source)
3. Use Loctite 638 bearing locker. ( My personal favorite cause it is relatively cheap)
4. Use a proper OEM Suzuki bearing as they have different tolerances than garden variety bearings and may, I repeat, may, solve my dilemma.
Anyone care to offer an opinion on these methods?
I would like to keep the bike long term and would like to use the best repair possible consistent with my inherent cheapness.
Best Regards: Andy
