I'll think of something.
I stuck this in an old thread, but I'm giving it a bump because I want some opinions on whether my idea on clutch-side bearings for an 056/045 would work. See below:
On a related but different note, I also noticed that somebody gives the 'standard' bearing number for the original bearing these saws had on the clutch side -- 527908A. It seems that some bearings shops might be able to get these:
This is an old thread; but maybe some people are still following it and I found something interesting I wanted to share.
I'm looking at an 056 I might take on as project saw -- I don't yet know the condition of the bearings, but I've been researching whether I can source them if I need to. And I've discovered that clutch-side bearings are all but impossible to find -- a 17mm id, 42mm od, 14.5mm wide bearing, single seal, reportedly.
Here's the interesting part -- apparently unicycles commonly used 42mm bearings that aren't readily available anymore. The solution for a unicycle is a 1mm x 12mm bearing shim that allows you to use astandard 40mm bearings in a housing meant for 42mm bearings. You can order them here: http://www.einradladen.com/Bearing-Shims-40mm-42mm
I think if you paired a shim with a standard (i.e. standard but a little more expensive than some others) 17x40x14.4mm, single-seal bearing(Timken or MRC/SKF make them), you'd have a clutch side solution for an 056 bearing. You probably need to use some Motoseal or the like on the shim to make sure it seals (or red loctite even).
Somebody who knows these saws well, tell me if I'm crazy -- I don't want misinformation circulating to unsuspecting victims, but if this would work it'd be good for people to know about it.

Hi. Does anyone know where can I buy crankshaft ball bearing for Stihl 045 chainsaw?
I think part number is 9523 003 0440
On the bearing is numberv 527908A FAG
