Re: Help! Rear cam plug/seal 1930 22A engine

Bob- I happen to have my transmission and clutch/flywheel assembly out right now and have a view of the rear of the motor.I'm replacing the ring gear on the flywheel(done) and "freshening" up the clutch components. The Welch plug on the back of the block looks to be about 2-3 inches in diameter, and is the convex "Welch" plug type, just like the plugs on the side of the block(like by the water pump). I don't think they used the core type cup shaped plugs in 1930. You measure the width of the hole and find a plug that will just fit, apply a little sealer and tap them in right in the center with a tool that will deform the plug enough to cinch it in tight.There is a hole in the bell housing where you can see all this and with the trans out you'll have access to tap the plug in(but it doesn't look like fun).Sorry if you know all this already. Not sure of the cam bearing fit, but the hole must face downward to allow drainage. I took a picture inside my bell housing of this plug, but I can't figure out how to post.(doesn't really show much)Ross

Thanks Ross.
With the flywheel off, I had access to the plug, or where the plug should have been. I also went to my spare 407 engine, removed the flywheel and looked at the cam plug there. Looked like the same set up.
I bought a new 2 inch convex expansion plug for 75 cents and installed it with the right amount of Permatex #2 (we all know how much that is!). I think it will work OK. I will put the flywheel, clutch, trans, etc back in tomorrow and give it a road test.
