unconventional transmission brake bands

[dhosh]

Not that I plan on trying anything different .... this is a question out of curiosity, as I wasn't able to search the old forums to appease myself ...

I would imagine Ford tested lots of materials for the transmission bands. I wonder how leather would work as a band material? I would think it might be a little squishy, or slimy, and possibly disintegrate, being bathed in oil. I know Chevy used leather as a clutch material ...

Please ... no dart throwing. This is just curiosity. I am not out to re-invent what has worked for 100 years. I run cotton bands.

People have used leather for temporary replacement linings, but as you said, being in a hot oily environment they would not hold up. The Chevrolet leather faced cone clutch was in a somewhat dry environment.

A cone clutch in a flywheel out in the open would also run about fifty degrees cooler than the inside of a hot running motor. Oil soaked under pressure and friction (as in a model T transmission) would turn leather to mush in a short time. A good cone clutch with an occasional squirt of neatsfoot oil can last for tens of thousands of miles if not abused too much.

Some weeks ago , I opened a 1911 engine and found these Trans. brake bands .
What do you think about these ????

Toon,
I have tore engines down with them in it, the brass that is imbedded in the material comes off and goes into the babbitt and then you would know what that looks like. They do work and hold well but pre engine failure from it.

My dear ole Dad mentioned using a tight weave cotton belt material such as was used in the military. Sounds logical. Just Sayin’

Comment to Anthonie,
I opened a 27 transmission and found a similar band to the one you posted a photo of. I also found the transmission full of the brass looking material woven in the band. I never found a manufacturer who made them but the ones on this T looked almost new when I took them out. I didn't put them back in because of the material coming off them and settling in the transmission.

[Mark Gregush]

They look to be brake band material sold by some company's. For applications such as car/truck etc service brakes or brakes used in power transmission boxes for industrial applications. The brass wire help keep the lining cool dissipating the heat.

Joe & Jim ; Thanks for your reaction , that is something to THINK about !!!!!

BTW. Joe , we have two model T's comming from OHIO

I thought this was about using leather for band lining ?
“Turn to mush”. ? I don’t think so. Think of frying bacon ! Heat and oil would eventually turn leather brittle and glazed, likely losing its ability to grab the drums efficiently. Times past, there have been posts about using harness leather (presumably with some success) - emergency repairs and depression era stories, I’d guess.

FWIW, “leather” covers a wide range of very different materials processed from the hides of animals. What kind of “leather” ? Bull shoulder ? Steer hide ? Top grain ? Skivers ? Belly leather ? Oak tanned ? Chrome tanned ? Vegetable tanned ? Latigo leather ? And that’s just “cow” hide. Horse hide and that of other species (goat, deer, elk) have very different properties and characteristics.

I’m sure I’ve seen pictures of cork inserts in T bands. Having just finished making a couple of cork inserted clutch discs I’m curious!

[Les Schubert]

Just for the heck of it, I might try making a cork inserted conventional T clutch. It would probably get 3 or 4 corked discs (each one would be about 1/4” thick when finished)

I can get the discs laser cut and I now have all the tools and knowledge for finishing it!

Regarding using military web belts for band lining... If you are considering this, be sure you use the old all-cotton web belts. When I first joined the Marines in 1972, we were issued cotton web belts. Around 1974, nylon web belts were issued, as they were easier to clean. The newer web belts, made of woven nylon and are not suitable to use as band linings as they will not absorb the cooling oil and will melt, causing a terrible mess. I have used the same set of Guinn’s wood bands for 10 years and would not use anything else. Jim Patrick

You can use leather for a rod bearing replacement to get back home if your traveling back to Canada from the States.

[Rich Bingham]

Here you go Les ! NOS

I would have used them but they smell funky and I think have damp rot. There were several brands marketed with cork inserts “back in the day”.

[Les Schubert]

Thank you Rich for the posting. I was sure I had seen a picture of them!

[Joe Bell]

Rich, Les, I have pulled many down with the cork in them, always wondered how the held up? What ever was between the cork crumbled but the cork was still good.

Potentially cork a Scandinavia band. It would be a interesting experiment. Another thought is to take a strip of Teflon and cork insert that

[Jerry VanOoteghem]

An "old timer" told me once that he used to punch holes in Scandinavia and glue in his own cork discs, which he cut from wine bottle corks. He said they lasted "forever".

[Rich Bingham]

Like Joe, I’ve found old cork insert linings in my parts stash. They didn’t look very much worn at all.
