How the heck do you get those things on? The bearings/washers I ordered from Brownell's arrived today. They APPEAR to be smaller in diameter than the yolk stud. Am I missing something or are these the wrong bearings?

Maybe those are the crane (yoke) tube washers that are used to shim out end play in the cylinder? If so, they would be the same diameter as the crane tube the cylinder rides on.

If we are talking S&W, they go inside the cylinder from the front, around the ejector rod. They fit against the inside back of the cylinder and can be tricky to fit. The headspace on an S&W is controlled by the back of the cylinder arbor bearing on the inside back of the cylinder. To decrease headspace, a shim can be inserted, to increase (rarely necessary) trim the back of the arbor.

Thanks. That's what it is. The instructions include a section for new S&W revolvers, which shows the bearing fitting over the yolk stud -and they have a diagram illustrating that. After carefully re-reading the whole set of instructions, I finally understand. I'm getting to know my revolver better than I wanted to...although that's a good thing I guess. Thanks again. :D

Jim- It is a S&W. They go in from the front? Front meaning toward the barrel I assume. I've got to go to a parent / teacher thang right now, but I'll play with it later. Tips are greatly appreciated. Thanks!!
