Hi Larry,
I have considered a 35ID bearing, but this the following limitations:
- The area where the bearing sits is worn slightly smaller than the seal face, so in order to get the sleeve on, so the seal area on the journal would probably also have to be machined (I will check with the machine shop, maybe they can get it on without touching the seal face).
- The 35ID is easily available, but is 17mm wide instead of 19mm (this could be fixed with 2mm spacers)
Sleeving the journal to the original size would be simpler/cleaner.
My thinking is that this is not a highly stressed area, so reduction effective diameter might be acceptable?
I am assuming that the journal diameter was sized by Kawasaki based on the bearing requirements and the fit to the crank web, and not based on the bending and torsion stresses.
Hi Motorrad,
The people I have spoken to regarding hard chroming and metal spraying do not seem interested in working on a pressed crank ? I will however do a bit more research on what is available locally (Johannesburg South Africa).
