The last engine I took apart had little ridges built up around the circlip
groove. I couldn't get these pins out either. I made a tool to pull the
pin out. It consited of a 3/8" bolt and a 2 washers. One washer was cut to
make a "C" shape, while the other is normal. You just slip the bolt through
the pin and then slip on the C washer. By tightning a nut on the bolt, the
pin will be pulled out. Once the pin has reached the outside of the piston,
You have to put a socket on the bolt and start tightning again.
The only other thing I had to do is file slightly on the bolt's head
(at the points) so it would slip through the pin. The bolt had a 9/16"head.
It is best to use a bolt with threads the whole length, as you could put
the socket on first, and pull the pin in one fell swoop.
After the pin was out I noticed that the little ridge had been cut
right out of the pistons. H very sharp piece of aluminum, so be carefull.
Good luck.
