how on earth do you remove these????

[RightWinger]

I ordered some cylinder bearings for a 686 that I thought needed them, I installed them and it was so tight the action would not work, so now I need to remove them and I have tried a dental pick, and a wire bore brush, but I cannot get the dang thing out....any suggestions?

Cutting torch?

Seriously, I've never had any that were so tight that a dental pick would not work quite easily. Maybe somebody here can help, but this one is new to me. Sorry, and good luck!

Yep, a blast of air or aerosol cleaner (like brake cleaner) normally does it.

The end of the crane tube cuts a groove into the inside surface of the cylinder. That edges of the groove have to be smoothed down or the shims can't lay down flat and they will bind.

To get the shims out, I can usually reach in from the front with a tiny screwdriver and flip them loose (take the ejector rod out first).

Can you elaborate on what you would use to smooth the inside surface of the cylinder?

Thanks

I have a "W" size drill bit with the shank end ground flat with a piece of 320 grit sandpaper glued to it. A "W" bit fits the cylinder perfectly.

I made the same tool: I have a full set of drills with square cut ends on the shanks. I take the drill that fits inside the cylinder hole (where the ejector rod goes) just snug with a little clearance. I use double sided tape to attach sandpaper to the shank end and use it to flatten the inside surface of the cylinder. It takes a while and you have to replace the paper often. Once it is smooth, the washers will work properly.
