Removing a stubborn fixed cup...MiamiJim's technique:
 
This is the poor mans version of the Stein tool. For those of you not familiar with it, the Stein tool holds a fix cup tool in place. It has 2 unique features, first is its abilty to anchor onto both nutted and bolt style spindles and its second feature is a threaded collar to compensate for different axle lengths.

Step 1: Picture 1. Loosen the adjustable cup a touch
Step 2: Picture 2. Place dedicated fixed cup tool onto fixed cup
Step 3: Picture 3. Place large washer over spindle. Washer must be a large enough diameter to cover the fixed cup. I use a 2" diameter washer.
Step 4: Picture 4. Stack smaller washers on top of larger washer. Use enough washers to cover the end of the square taper. I use 1 3/4" washers.
Step 5: Picture 5. Secure washers in place with either the spindle nut or bolt
Step 6: Picture 6. Apply torque. For this cup I used a size 10 1/2.

you think that is funny you should see the cheater bar on my fixed cup wrench.

thanks miami, I have been trying to think of the company that made that tool for weeks.

I wish I had a 34mm wrench to remove the friggin' fixed cup on my itty bitty Moto.
I'll keep this in mind when I do need something like this.

Can I send you a Cilo with the R cup "fixed"? I really need it off.

Can I assume that the fixed cup in picture six is not a British threaded cup with left hand threads?

Nice, thanks for that tip! I've yet to encounter a fixed cup that is unmoved by my mighty bench vise though...

That's a sweet looking car you have there Jim.

Probably a good method for installing the cups on italian threaded BB as well (and course french too I guess) in order to tighten them down good without the wrench slipping and busting your knuckles on something that your BB doesnt work loose 10kms down the road.

Back in my shop days we had a 4 foot cheater bar!! If you work on alot of bike the Stein tool is well worth the money.

I've used my bench vice as well but on occasion the cup flats aren't thick enough for the vice to get a good grip on.

Good catch!!! Thats actualy a re-assembly pic. Upon re-assembly its crucial for the adjusting cup to be loose, it's tight and the fixed side is tightened down you'll crush the bearings.

Thanks, it'd be sweeter if it wasnt leaking oil.....and transmission fluid.

I wish I would've see this about an hour ago. I just got done struggling to keep the tool on with this setup attached below. Good tip for future reference.

This may be a stretch, but I'm going to guess French. Also, why does the lock ring on the other side have to be loosened?

Its British. Thats actualy an assembly pic but it works the same for removal. Loosening of the adjustable cup prevents accidental binding of the bearings.
