I agree with Tom.  If you are pulling both heads anyway, you might as
well do all four pistons.  If you have alot of patience and a little
luck you can use a big hose clamp as a ring compressor tool.  Go to
Home Depot and try to find one that is at least 3/4" wide and can close
down to 94mm without a ton of extra clamp (or just cut the extra clamp
off).  Put a bunch of oil on the piston and have fun.  After the first
couple of trys you should get the knack of it.  I have used this method
quite a few times and it works like a charm.  I have never pulled the
piston pins in any waterboxer (so far).  I have the nice Goetz rings if
you need a set.

Hope this helps,
