wrist pin removal

[spoolinhard]

I am rebuilding my 360 and need to know what the best way to remove the wrist pins. I would prefer not to go to a professional, and I own a press, although I know theres more to getting them out than simply pressing them.
any ideas?
thanks

You need to support the piston and it needs to be long enough for the pin to push through the ID of it until it clears the rod. The push pin needs to fit square with the wrist pin and the press ram. I usually press mine out cold unless they are overly tight but I do heat up my rods some what on assembly. My piston support is a round stand that's ground at the top to clear the piston head and has just enough room for the wrist pin to fit into it when pressed....

What do you heat up your rods with. I tried everything you said before I posted, and it acted like it was going to break something and didnt move the pin.

So far in the 20 years I've been pressing this stuff, I've never had to heat up a rod to get the pin out and yeah, sometimes it seems like it's not going to move but it will. On assembly, I have an aluminum cylinder 1/4" wall with a cut out on the bottom just big enough for it to go over the top of the rod and put a heat lamp on top of the cylinder. The lamp ends up about 1/4" away from the rod. It sits on top of a block of steel. It makes the rod too hot to hold and expands it just enough to make it easier to insert a new pin. You're only looking for a few tenths of a thousands of an inch expansion. Most shops turn the damn things blue on their rod heaters and I don't care for that but if you would like to heat it up some for disassembly, use a torch with a small tip and heat the end using a circular motion changing sides a few times. This will let the heat spread throughout the top. I would have it in the press at the time of the heating with some pressure on the ram and the rod will release the pin and then you can put the torch down and finish pressing. A buddy of mine does it like that but I've never had any problems doing it my way either.

well I got over my fear of dammaging the rods and really put the press to them. They made quite a bang breaking loose but came out no problem and without dammage.

I heated my rods up with a torch, and with the pin partially in the piston oiled up and ready to go, I just lined it all up and pushed the pin in by hand and centered it by eye.
