HELP! Wrist Pin Removal


Recommended Posts

Yeah - you can make a hook out of some thin bar stock and pull them out. I have a tool made by Shadow (he's not around much anymore on this board) that uses a split-arbor device to grab them and pull them out. It's an interesting device, but you need at least a small lathe and mill to make one....

 

Make your hook with a bend in the end that you can use a claw hammer on to "lever" the pins out.

You can make an uber-simple slide hammer from a piece of 3/8" threaded rod and a piece of 1/2" sch40 pipe, along with a couple nuts. It's the best way to pull them, I've tried to pull them by pressure before, and you really do need that -hit- from a slide hammer to get past the coked-on oil crud.

If all else fails split the block, tilt the halves as wide as they can on each side and remove 2 rods at a time. Then remove the pistons with the rod halves disconnected from the crank.

 

Did that for my old block to recycle it. No too bad, but either count on replacing the lifters, or keep close track of them, since they like to fall out of the case once it's split.

Thats what I ended up doing, and it worked. Now to do the same to my EA71! WooHoo!!
