Model T Ford Forum: Forum 2017: Removing flywheel cap screws help needed
Top of pagePrevious messageNext messageBottom of page Link to this message  By Eric Dunlap - Orlando, Florida on Sunday, February 19, 2017 - 03:23 pm:

I need to remove the four flywheel cap screws. Every wrench or socket that I try to use seems to provide a poor fit and I cannot grip the head of the bolt. Any suggestions on how to remove these four screws so I can remove the magneto and transmission from the engine?

The Snap on socket might do the trick. Or try a socket with a universal joint.

I have used the 3/8 drive craftsman for years, have broke a few sockets and ratchets but they are thin walled six points and they do the job , hope this helps, the nice part they are guaranteed when you break them!!

Use the Ford wrench (5Z-210) or make your own. The head size is 11/16".

I have an old Montgomery Wards 1/2" drive socket set that I bought at a pawn shop in the late 1970's. The 11/16" socket combined with the breaker bar fits perfectly on the Model T flywheel bolts.

I ground the edges off an 11/16 inch socket so that it would fit and used a breaker bar. Success. All four of the bolts are removed. It appears that there are two dowels that need to be removed.. I am not sure which direction to drive them out.

The dowels stay in the flywheel. Once the bolts are out the transmission assembly will come off. I pull it off by hand if the assembly is horizontal; others prefer to have the assembly mounted nose down on an engine stand and use a come-along mounted overhead. The tranny assembly tips the scales at a few nicks shy of 100 lbs.

I figured it out. With the transmission facing up I hit the dowel pins and they separated the mag from the flywheel. Success. Thanks for all of your advice.

"I hit the dowel pins and they separated the mag from the flywheel" I hope you mean flywheel from crank shaft? You shouldn't have to hit anything, a little rocking back and forth usually gets it loose to remove.

Below are some pics from my adventure with removing the flywheel today. Thanks again to the folks above who were so quick with advice.

Below is the socket I ground a bit to fit over the flywheel cap screw/bolt heads.

Next are pics of the flywheel with one of the dowel pins still in place (definitely needs a new ring gear), the mag (definitely needs a rebuild), and a pic of where the mag attaches to the motor (including a wasp nest). There were lots and lots of metal shavings on the magnets.
