Sometimes, creativity is necessary. I once had to find a piece of pipe that fit over my roll pin punch, and then another long rod that fit in the other end of the tube to temporarily add about a 3' extension to my roll pin punch so I could get it out where I could swing a large hammer. It might be something to consider. If you can't swing the hammer or can't get a big enough hammer in there, you'll never get it out.

Well, the week long battle is finally over! It turns out all I needed was the proverbial BIG F'ing Hammer! My neighbor came over with a small hand sledge and with a few hits the spirol pin came out. Then it was a bear to get the rockshaft out of the tractor because it was rusted to the lift arms. Once everything was apart I cleaned the rockshaft up well with the wire wheel and put everything back together. It wasn't too easy getting those spirol pins in either, it was a pain getting the holes lined up just right. Anyway, it is done. The only problem I now have is this: when the hydraulic piston is fully extended, the clevis will just hit the hydro fan. Does that mean that my fan is in the wrong place? It never hit with the old clevis. Any ideas? Now I just need to mount up a mower deck or the tiller to try it out. Thanks for the ideas and encouragement.

Another option, maybe?
 

I'm engaged with making a 1650 from an 1100. This entailed removal of the 4 speed manual Peerless trans and rear and installing the ported hydrostat. When I removed the brake rockshaft (the brake and clutch arms are reversed on the shaft), I needed to drive the roll pins out. I supported the shaft with a jackstand as close as possible to the arm with the base on the concrete floor and the roll pins were easier to drive out.

From reading the postings in this forum, it's unclear if the posters did this and from my experience, you can beat the roll pins til the cows come home without much success because the tires absorb the shock needed to get the pins moving. Perhaps I'm misreading between the lines, but PB Blaster and a 3# hammer along with the support of the jackstand usually work quickly for me. Give it a try!
