ball bearing size for clutch pushrod on hydraulic clutch?

the solution from the aftermarket for Kawasaki's, that I fitted to my recent KZ 650 rebuild, is almost exactly what you illustrate in your post, a bearing replacement. See it here    http://www.z1enterprises.com/Kawasaki-Roller-Clutch-Push-Rod-Kit-257.aspx

Cool, thanks! I knew someone else should have come to that solution years ago...  ;)

@ Piet: there are sealed version of this bearing existing according to the SKF catalogue. But even if not, one could machine away some "meat" of the original piston and make a press-fit cover that takes the same oil-seal that is sitting inside the main gear shaft that seals the push-rod against the main shaft, no? Shouldn't be to hard to make for a man with your skills...  ;) Happy to lent one of my bikes for the tests; preferably the 1000 SFC engine you wanted to fix the head of...  :D
 
There's one available for enfields:

I have one in bits in the garage at the moment - the clutch pushrod is the same diameter as a Laverda one.

For 8 quid, I might pick one up - I need to order a metric crapload of Enfield bits anyway....

i bought one for exactly this purpose a year ago for my brother's 3C. My local bearing shop sells balls individually for a few cents each. Actually I bought two, 1/4" and 5/16" because I didn't know the size.
If anyone wants individual balls, I can get some and drop them in the mail.

Seems a bit odd that your shops will only sell them by the bucket load. Are they wholesalers?

Cheers,

Hi Cam

yeah, best selection at the commerical trades supplier, I set up a commercial account with them years ago through one of my corporations, but usually I am buying things like a pair of wheel bearings etc, so no problems. Don't know why they have a silly rule re ball bearings in bulk, but I solved my issue at the bicycle shop, so no worries...
