It's easy. The problem is getting to it.

It depends on the kind of job you do. If you are concerned about saving the low speed gear like I might, you would remove the gear sleeve from the drum and rivit it to another low speed drum. If not, then substitute another low speed drum, gear and all. If you do the latter, you need to install a new bushing and bore or ream it to fit. Whatever you do, you have to pull the engine and disassemble the tranmission. A critical tool to have is a driven gear puller.

Jay, where are you located? I have all the proper tools and a good used drum (magnafluxed and absolutely free of cracks) to do the job.

Do you have any idea, Jay, what caused the crack?

I do, heat! That drum is in the middle and gets hotter quicker for that reason and becuse it is used more. The reverse drum and band are usually like new. The brake drum may need lugs on the inside and may crack on occasion.

Kevlar bands can get hotter before they begin to smoke and smell. That situation may also often lead to a cracked drum, usually low.

The first secret to driving a Model T is to keep your feet off all the pedals as much as possible.

The second secret is to get the engine running well enough to go up hill in high gear. That usually requires having the coils redone and perhaps the carb rebuilt.

The third secret is to never drive in a slow parade that requires low gear to drive slow enough.

If you hold the pedal down hard and the band is adjusted right you should have no problem with the low drum. The problem is caused either by the adjustment being too tight which causes the band to drag while you are in high gear or neutral or by slipping the band by not depressing the pedal all the way, or having the adjustment so loose that it slips when the pedal is pressed down hard. With correct adjustment and the band and durm will not overheat.
