Transmission Bands

Hello everyone. I purchased a 1912 touring this weekend and have started to get into the engine. The pictures below are of the transmission bands. Are the bands supposed to line up exactly over each drum? I have tried to highlight where the bands appear to be slightly off the drums. I will be changing the lining to Kevlar this weekend, but was curious to see if anyone had any thoughts on whether or not this was a problem. I appreciate your input. Mike in Houston

Here is a picture showing the brake band and its position relative to the drum. The arrow shows how far over the band is.

It sure looks like just the difference in where the metal ring was rivited to the ear.i would look and see if they were not put in an orentation other than where they should be.i dont think it will hurt much if when you reline you compensate and cheat the lining over just that hair.either way i think it is no big deal but a different band that is centered would be better yet.but that is just my opinion.
 
Brake bands before the improved model used the drive plate as part of brake drum. So it looks normal. The low band looks ok except the spring is forcing it back. I would put a washer between the spring and ear on the band. You might do the same for any spring that is doing the same thing. I don't think new springs will help this. The ears are worn some. If it doesn't have quick change bands now you might want to get some and install now. It will save a bit of work later.
 
Thanks guys for the quick replies.

Redmodelt - I was curious about your statement "brake bands before the improved model used the drive plate as part of the brake drum." By "drive plate," are you meaning the "transmission driving plate assembly." The brake band definitely hangs out over this plate. When did the improved model you refer to come out?

Thanks again for your help.
 
The improved model t refers to late 1925 to 1927.
By "drive plate," are you meaning the "transmission driving plate assembly." Yes.
 
Don't waste your money on quick change bands. The early transmission covers do not have clearance to remove or install them.
 
The early t's are the ones before starters were available' older than about 18. I have not tried the bands with the button type ear attchment.
 
I forgot to add, if you put quick change bands in you will have to change to the 25 to 27 outside adjuster for the low band. Check the photo, this car has the larger tapered door type cover. The removable ear goes on the drivers side (US cars). the aluminum and pre starter cast iron hogs head should have the same amount of room inside as the starter type. Yes the tab type are a bit hard to get in with fresh lining. I had quick change bands in my 1918 with the non starter hogs head and I could change them with out pulling it.
 
Part of the "joy" of owning an early car... but it's amazing how adept you get at pulling and replaceing that hogshead.
 
I got to the point where I was really good at it and folks brought me a lot of cars of every year to replace band linings. Early ones are a pain. Take your time. Stuff lots of rags in there to catch wayward parts and count the rags going in and coming out. You can do it in an hour or you can do it in a day. Just be patient and keep your cool.
