My 54 has 1954 on the tires. Never have I added air.

I changed the break in oil (30w) to T4 15w-40 and the noise is gone. It’s been in there 2+ years but very low miles.

I’ve done that! My Pertronix was fine, coil was bad.

I moved my M37 key to my daily driver keychain and that helps me remember to take the key.

Same noise with the belt off, and after torquing the manifold (several nuts were loose).

Same noise with the clutch in or out

Sounds like it's coming from the dizzy. I don't think it's the generator or water pump. This is at idle:

Anybody got ideas?

Here is what I did. Need a 3-way key switch.

I always start with John at Midwest.

You’re missing the hold down latches. They look like the hold down latches for the hood but with a different handle. Midwest Military has them im sure.

1st Parade!
I was worried about engine temps but that was not an issue. Hardest part was finding a good gear. 1st Low was too slow, 2nd low was too fast. I needed a 1 1/2 gear!

I’ve heard from several sources the engines were Chrysler Silver when they left the factory.

None, it is an interference fit. Once you put one on you’ll see there is no need for sealant.

Tank Renu was worth the money in my experience so far.

You can repair it by removing the flange. Most likely the seal has worn some grooves into the shaft. You’ll want to redi sleeve it as well as installing a new sleeve. Not a hard job, as long as you have big cheater bars.

Before cutting up the threads with the stud remover, did you try red loctite on the outer nut?
