I like to file flats on the shaft where the set screws touch . Plus they don't need to be to tight , just enough to keep it from slipping on the shaft .

With a drop of thread locker on the threads of the set screw.

The time to replace bearings will come soon. The Sa204-12 arrived today. One screw goes all the way through the collar. Then there's a hole in the collar that only goes part way through, coming from the outside. A little confused


Some more reading required

It doesn't take too long to find out that this type of collar is an excentric locking type. Installation instructions found online say that the collar locks in by turning, after which it gets set by punching in the blank hole in the direction of shaft rotation. Last step is to tighten the set screw.

I'll try that.

I couldn't figure out how the collar gets tightened on the shaft because the collar rotates freely around the inner race of the bearing. Until I looked more carefully at it. Iit's called excentric because, guess what?! - it is!


Look at the thickness of the inner race and collar recess around the circle. Now I see how it gets tight on the shaft when the collar rotates around the bearing race.

This is the correct tool for the job . The pin goes in that half drilled hole . But a punch works too , just not as nicely and gives you a reason to get out the hammer .

And if you want to buy one, it's called a "pin wrench".

Bob

I do not want to buy a pin wrench Sam I am.

But thank you

Bob, I found a pile of pin and hock wrenches at a garage sale. They are the best when removing parts that were over tightened and hammered.
These are a small sample of them.

Spike

I like the hammer and punch method, especially when taking one off. The punch leaves a mark so I know which way to turn it loose. Unless it has been on and off a few times
