OEM bearings are manufactured to JIS 0, a good general purpose bearing. Bearings with more demanding loads and RPM ratings are JIS 5 or better. Often industrial bearings are superior to OEM bearings as well as cheaper because they are not from Honda or any extra middle man.
I wash them in hot with a good degreasing soap then bead blast at home then take them for hydro blasting. This brake plate was a pitted mess. You can get the level of shine you want.
My missus has a horse. I highly recommend this as the horse costs more and is a bigger pain in the ass that I could ever be. Hence I have five bikes. It's a great system.
Very Timely thread. I'm considering a Rickman build and 836 is the way to go. It's a tough choice all around. I'd end up with a machine to valuable to keep that would tap out the pension for a year. Damn it would be great though.
I have a chance at a Rickman kit for a 1974 Honda 750. The kit might be for sale once I know the exact condition and the completeness of the parts. Just putting this out there to see if there is any interest. A Rickman build, a proper one, is a pricy project. I'd like to flip it to fund other...
The $7 ( Canadian ) makes getting new ones pretty easy. The old ones are shot. One might be serviceable but the other one is crunchy. The original bearings are not sealed and I can see dents in the ball retainer. I am going to repack the final drive bearing as it looks pretty good. The hub is...
Thanks for the reply. I've been reading about bearing tolerances and classes, ABEC ratings etc. and I might be over thinking it. Bearings for industrial applications often need higher tolerances for load and RPM and usually have a higher ABEC rating than those manufactured for wheel bearings...
The 1977 model has a hard to find 17 inch rear wheel. Will an 18 slide in without modification? The stock 17 is looking pretty good, ready for powdercoating but I may want to go higher end as the bike is in great restoerable shape.
Restoring a 1977 CB750K on a budget. Wheel bearings are running $30-$50 on line (6304LU bearing) but I can get the 6304 2RS at Princess Auto for $7, same dimensions, 2RS indicating they are sealed on both sides. Is anyone using these bearings? They sure look and feel good
