removing roll pins

Fri Aug 23, 2013 12:51 pm

I learned a trick for removing spring type roll pins today. I was working on the throttle of Jeff's (non mechanic neighbor) 444 today and needed to get the lower roll pin in this picture out to replace the friction disk.

In addition to it being hard to get too, there appeared to be some weld gobbed around the pin, which I had to cut off with the Dremel. I tried to drive it out with a punch, but couldn't move it due to not being able to backup the shaft and keep it from sprining. I tried drilling it, but all I accomplished was dulling my drill bit. After thinking a little bit I remembered Jeff mentioning he was wondering about using an air chisel. I grabbed my air chisel and ground the punch bit that came with it down to the size of the roll pin, and the pin popped out almost as soon as I pulled the trigger. I think I will get some extra punches to grind down to pin sizes as I need them.

Thanks, John. That is one to store for later use. Oh, I've never told you , but I really miss your musclebound avatar. :) :)

Never seen a roll pin on a cub, which is the reason I posted it here instead of the cub forum.

I know that.. it is still a great tip and one many of us can use. There are roll pins on different implements etc., and it is a good tip.

Your right Rudi, a good tip is a good tip. Thanks John for reminding me. I had used the air hammer on some at work before retirement but I had forgotten about it.

An air hammer is a great tool when used right. I almost always forget about it though. The other day I was watching the owner at the local garage hammering to no avail on a ball joint when I happened to think of the air hammer. A minute or so with it and out came the joint.

Now if I could just find someone that made them with assorted size punches so I didn't have to grind one down when I need a different size, because my grinding is not too exact.

John if I remember correctly Snap On used to have them in a few sizes, (don't remember how many though) and I would guess the other big name guys would probably have some also. Of course they're quite pricey.

I think it may have three! Others may beg to differ with you on "real cubs".

I also mentioned this on YTMAG.com (yesterdays tractors), and one of the replies was that the palm nailers also worked good plus you could use standard punches in them.
