Great idea, Keith. Great shot too, clearly demonstrating the application.
Good work!

agree totally with Dave's statement, if you don't use method 1 below you

I have had a couple of engines that required "some force" to remove the
wrist pin, and others that required more force than I could provide. This
lead me creating a simple tool to pry the wrist pin out. Get a long 4 mm
screw and a butterfly nut and thread it through a hard flat steel rod.
Screw the end of the 4 mm screw into the wrist pin and then turn the butterfly
nut down against the steel rod that is against the exhaust port.
To protect the side of the piston I also put popsicle sticks between the
piston and the inside wall of the crank case.</FONT></FONT> <FONT FACE="Arial"><FONT SIZE=-1>This
is sort of a reverse gear puller. See picture at link below:</FONT></FONT> <FONT FACE="Arial"><FONT SIZE=-1><A HREF="http://www.fototime.com/865BF0EA2103D32/orig.jpg">http://www.fototime.com/865BF0EA2103D32/orig.jpg</A></FONT></FONT> <FONT FACE="Arial"><FONT SIZE=-1>Keith

1st method is the way to go. If the second method works - it
is only because there is enough play in the conrod that the conrod (and/or
possibly the wrist pin, or piston) need to be replaced. The conrod
will most certainly need to be replaced if the "pry" method is used. Dave

Original message --------------One way, the way I have done it. Pull
the head and the sleeve, the sleeve should slide out; if not I put a wood
dowel in the exhaust port and nudge it up using a prop installed then you
can grip it and move it out. The sleeve is aluminum so use care. Go
in through the exhaust port with a narrow plier or hemostat and remove
the circlip holding the wrist pin in the piston, you can do this in a baggy
if you dont have a spare circlip cause the clip might get away from you.
Then use one of the head bolts and thread it into the wrist pin through
the exhaust port and pull the pin, this might take some force depending
on how much then engines been ran. If you can clean any crude out thats
in the pin area that might help. The piston will come off, the rod will
fall off the crank and come out the cylinder. An alternate way that
I have heard about is to remove the sleeve and position the rod so you
can pry it off the crank leaving the piston and rod together. Brian
