Title: Bean Can Thrust washers
Post by: mimmo66 on August 25, 2009, 11:53:29 PM

I was cleaning up a spare Bean Can, and 'accidentally' broke one of those 'carbon like' Thrust Washers that sits between the two steel ones at the shaft end side.

Been looking online without much success yet.

These buggers are OD <1" ID .5" thickness .02"

Thank you for any help or suggestions,

They are not available, unless you have a 'donor' beancan to take parts from .

Dom, you done screwed the pooch. However, I would see about finding some sort of similar phenolic "carbon-like" material close to the thickness and go about making up my own. Maybe an electronics-style hobby shop. A Forstner bit would cut the i.d. hole easily. Then rough out the outer diameter, then gently sand to final size. That'll get it.

Coincidence you're messing with a bean can as I'm currently replacing the Hall sensor in one of mine.

This is a wild guess but if I was looking I would try someplace like McMaster-Carr, http://www.mcmaster.com/#thrust-washers/=3dbi63, Graingers, or a bearing supply house for a similar replacement.

Monte,
It was a good practice to open one up and see the guts out first hand though; I did install something up by splicing one up found at ACE.

I believe this spacer to be an insulating bit to disperse heat from the engine case, what do you think?

During my playtime I've noticed the black rubber bits holding the springs on the oscillating 'arm' to be slightly worn out. these spring retainers have two little rubber shoulders with a groove keeping the spring in; try to replace those!

I had some funny moments on reassembly, the darn thing would just not go in all the way; after some time I realized that the assembly was not seated in correctly.

The Hall Sensor has a metal bit on the inner face, it showed some oxidation/rust, I tried to clean it as best as I could, does it make any difference?

When the time comes will see if it works, planning on keeping it as a spare for the 'just in case situation'

Ah, yes... the local Ace Hardware & BMW Emporium has gotten many an Airhead back on the road.

Your guess is as good as mine on the "insulating" washer. Could be that or just a no-load spacer.

I'm sure the removal of corrosion is a good idea. The Hall sensor "senses" the opening in the rotating metal shield and that triggers the impulse up the harness.

Oughta work for you.  [smiley=thumbup.gif]   Monte
