Model T Ford Forum: Forum 2014: Cracked '26 low speed band
Top of pagePrevious messageNext messageBottom of page Link to this message  By Warren Henderson on Monday, December 15, 2014 - 11:01 am:

I have two cracks in my low speed band and would like some advise as to what is best way to go. Should I try replacing with rebuilt band (from where or whom) or should I try welding the band I have?

Happy motoring,

Warren

Do not try to weld the drum. This can shatter and lock up the whole transmission with possibility of even destroying the engine or rear axle. I will show you pictures of what happened to one of mine.

Find either a good used drum, or spend the money to buy a new one and have it riveted to your good gear. If the gear is not good or the hub is cracked, find another.

As you can see, the drum is darkened in color. That was caused by the band slipping. Usually this happens if it is tightened too tight. but it could also happen if you are using the low for an extended time such as climbing a steep hill. If the band is too loose when you depress it it slips. So either too tight or too loose adjustment can lead to this failure.

Be sure the cam and notch are good and that the pedal is not bent so that the band is completely tight when the pedal is one inch above the floorboard, but when the pedal is in the neutral position it is completely loose. You should be able to crank the engine when in neutral without the car moving forward and also be able to push the car in neutral without the engine turning.

See my pictures.



When that happened, I skidded to a stop in the middle of the road and could not even push the car out of the way. We had to get a trailer and jack up one rear wheel on a floor jack to be able to winch it up onto the trailer. Fortunately nothing else but the transmission was broken.
This happened twice before I finally found out that the best place for the low pedal adjustment was below the floorboard. From many years of wear and bending of the pedal, the parts had worn. I replaced the shaft, the cam, and the notch and also bent the pedal back toward the seat to fix it.

Warren,

You say 'band' but show photo of the transmission drums, what is it the band or the drum?

If it is the drum replace same with the band. If you need a replacement band or drum let me know; as I have both good used.

Thank you Norm, looks like you really dodge the bullet that time. I have three great friends (Ken, Paul & Steve, fellow CNHMTC club members) who have been helping me with my coupe. So far they have helped (did most of the work and supplied the needed expertise) to rebuild the rear end and were going to help put in new Kevlar bands when we found the cracked low speed drum.

Happy motoring,

Warren

Warren, that's a cracked low gear drum I'm looking at in your pic. You've already removed the bands.

The bad news is you've got to replace that drum. Requires a tear-down. Probably shouldn't weld the drum. I'm sure it's been done before but those things can blow apart while you're driving and wreck your whole transmission.

Good used drums are pretty readily available. Dave Huson often advertises them in the classified section. Others as well.

Dave's Restoration, ph # 740 360-1904, makes new transmission drums, about $200 for a low.

Good luck, Bob

Andy & Bob, thanks for the help. I obviously need a lot of help, calling it a band when what I mean is a drum!

Happy motoring,

Warren

Warren,

Is that in the "new" coupe?
If so bummer.....I would definitely go to a newly made drum and not look back

Good luck.
Larry

Don't let your friends drive on cracked drums.


We make new drums with new gears.

Warren: I would also check the reverse as typically the drums crack in pairs.

Thanks again to everyone for their helpful suggestions! I must say that the Model T owners / members are all a great help and a wonderful group to be associated with. Dick Welch ( a very long time friend and Model T expert) who helped me with the '17, has always been more than willing to help me with parts and his expertise. In fact he is the one who got me started in the wonderful world of Model T's. To all the newbies I highly recommend joining your local Model T club, where members will help you with any problems you need solving.

Happy motoring,

Warren

PS: Larry, yes and that is a great looking touring!

Check out Daves Restoration and machine. He makes quality drums. If your hub is still good on your cracked drum he will sell you a new drum with your good gear for 225.00 plus tax and shipping.
740-360-1904

He advertises in the vintage Ford magazine.

Ralph, based on Warrens comments above, just the thought of getting Kevlar bands cracked that one!

I bought a used drum to replace my cracked low drum but have since bought new low and reverse drums from Dave Nolting. The new parts are beautiful and meaty looking. Everything looks reinforced compared to the original design.

I would have to say that kelvar bands did not crack that drum. Perhaps the fact it is 88 years old... A perfect used drum, or an even better idea would be go new and never worry about it for another 88 years.
