As the final stage of my 1985 Fuji del Rey restoration I decided to do the bottom bracket. The wheels and head were done.
I found the hook lock ring very tight. I soaked it several times with Liquid wrench few days before to loosen it up. The hook wrench just was not enough. I finally got it off using a chisel and a 5lb mini sledge. That too took a few whacks and the lock ring notches got damaged. The bearings were loose not caged. So I tried to get the other side off using the wrench so that I could reload the bearings . Not even the hammer could budge it.
This the tool for the stock crank side.

Tried getting caged bearings as putting in loose bearings from the opposite side and the seal was just impractical. Also wanted a new notch lock ring.
Both not available, however the dealer had Shimano UN54 sealed bracket of correct size (68X127) and that was a good choice.
He had a heavy duty removal tool that I have not seen anywhere and he too had to use a big hammer. The tool bolted through the bb and held the large attached wrench in place than a few whacks with a hammer .
There was not much rust they just were very tight, mostly.
It was similar to the below tool but more heavy duty.Anyone see any special tools for this. I could not find anything much besides bb wrenches .

BTW I was surprised at the UN54 tightening torque figures 0f 400-600 inch lbs. My Motorcycle heads are only 300 inch lbs. WOW.
