The hot ticket is use the Merc puller. Jay Smith Racing makes a combination puller / lifting eye. You can get it here:<br /><br /> Jay Smith Racing <br /><br />c/6<br /><br />Hooty

I want to make my own puller and I need to know what size the big I/D of the flywheel is. It appears to be about 1 1/2 by? thread. I would like to make it at work today before I go home. Thanks

A friend just made one for me, he used a tool that has several blades with different thread sizes, he tried one and came up with the exact number of threads. worked great.

Just a suggestion, why don’t you buy a lifting eye from ebay for about $30.00 and drill and tap it to what you have available?
