I find KROIL works better than PB Blaster. A 50/50 mix of acetone and ATF works just as good as KROIL too.

If it is stripped, use a "F" drill ( .257 ) to make a spot on the top set screw. Just go far enough to get full diameter . Change to a 13/64" or 3/16" drill and SLOWLY drill thru the set screws. Use oil take your time. If the drill bit gets dull, resharpen or use a new/fresh on.

Once thru, use the 13/64 " thru the hole and then use a 1/4-20 NC tap to clean the threads. Purchase all new set screws when you reassemble.

I've already had my fun with stripped set screws :bash2:

now how about this bearing. I read that I need to hit this inner part clock wise to loosen it but it does not seem to have to place to hit that I have seen in other pics.

Look at my picture with the hand drill in it. Behind the bearing at about 11:00 is a shallow hole. That is what you hit with a punch to get the eccentric loose.

Now I hit with a punch using that small hole as a target CCW correct? It's not moving so I just want to know if I can/should really give it a good whack. It's getting late here at the Cub repair shop which happens to be my garage directly under my daughter's bedroom so I'll have to hold off on the procedure till tomorrow.

Check to see if there is another hole 90* from the set screw and nut. If not, put the set screw and nut back in ( but not against ) and hit that so you don't mess up the threads.
