RE: Saito 82a Ceramic Bearing Failure
Good points Don.
On seating the bearings. When the components are hot / cold the bearings will simply fall out of the case until the temperature of the case / bearings normalize. Given that the case is 350 degrees it was difficult to keep the bearings seated. In retrospect I'm thinking that this is what happened to the rear bearing. When the temps normalized the bearing was not seated for the entire 360 degrees.
My concern is if the rear of the crank is given a whack the total of that force will be on the small race that is seated on the crank - not the outside race that is incorrectly seated in the case. How about using the backside of a socket whose outside diameter matches the outside diameter of the bearing? Obviously, the front bearing can be seated with a standard bearing driver (just using a small hammer).
Thanks again for the input - this hobby has so darn many learning opportunities!!!!!!!!!!!!!
PS - I should probably disassemble both the Saito 91 and Saito 100 and re-seat the bearings!
