Unhappy Re: key pullers

I have one I could send a photo of if you like. It is hardened steel about 1/4" thick and is shaped like a half moon. It is pointed at one end and gradually increases in size. You put it under the head of the gib key and use a large adjustable wrench to keep it in place as you drive it in with a hammer. Put the wrench across the puller and the shaft to hold the puller against the key. Those keys are a pain especially if someone cuts the head off. I have welded large bolt rods to the end of broken keys and pulled them off with nuts and washers over a small pipe nipple for a spacer. In some cases I have had to drill out the key and collapse it in place. If I can be of any help please let me know. I have removed many of those buggers and I hated every one.
Jeff

Mark Mahoney told me I can use a cold rolled steel chisel. Chip it away I guess?

You use the chisel at right angles to the shaft between flywheel hub & head of key and use taper of chisel to wedge key out.
Some people also use a lock ring remover tool used on truck tire with split rims ... I have not had much luck with one.
The one I use most often was sold by Harvey Cain who used to advertise in GEM. It is similar to one sold by Hit & Miss but has a 10 degree bevel that keeps tool in place without having to use the large adjustable wrench.
Photo shows it being used to remove a Stover Duro flywheel. Works slick if you have a good head on the key.

Doug, is the bevel on the overall length of the puller, or on the side where it engages the head?

Frank,
The bevel is working on the head of key in photo. Tool is bevelled along the whole length of the side facing camera. It digs into gib head holding the tool in place & saves using that third hand to hold the wrench. Use plenty of oil. Tool has to be driven from right to left.

Thats a really good idea to keep the puller from pulling out. Thanks for clarifying that. Ill have to put a bevel on mine instead of using the 24" adjustable on the big cranks.
Thanks Doug!!
