There must be a ghost in the ******....

I have been working on a friend's 1923 Ford Model T Touring car over the winter and into the spring now, and it has severe difficulty in getting the car to go in reverse.

I replaced the old cotton bands with Kevlar bands over the winter, but never adjusted them other than running it up on jack stands and tightening them by how much pedal travel each band had (it was 10 degrees outside, no way am I that tough to run it around in those temps). It ran OK in all gears, but reverse was a bit grudging, I figured it would work in once the spring came and my friend put some miles on the bands.

According to the owner, this car has never really had a true nuetral in the 10 years he has owned it, and it has always creeped forward. The reverse has worked fine in the past, but not now. Now that these new bands are in, it still has a forward creep, although adjusting the bands can eliminate it for a while, but the creep returns once it has run just a minute or two.

The ghost in the ****** now will simply not let reverse engage unless you let it slip some, with lots of accelerator. Giving it full oomph on the reverse pedal and lots of gas, it will just kill the engine. It is as if the forward is fighting the reverse, and the reverse loses. I have replaced the low speed linkage, and adjust the bands and it behaves for a minute or two, then goes back to its evil ways.

I have heard that perhaps a bad reverse drum is at work here, but do not know how that would be diagnosed. If anyone has seen this before, let me know how you remedied the problem, as this is very frustrating for all involved (especially the owner).
 
The symptoms you describe might be due to the clutch lever screw needing adjustment. This is the hex head bolt that rides on the cam on the hand brake cross shaft. The blue book says to turn it in until the low speed pedal moves 1 3/4 inches downward when the hand brake is pulled back all the way.

It says that if the car still creeps after doing this adjustment, the clutch might be adjusted too tightly.
 
OKay. First off adjusting the bands by their travel in relation to the floor isn't correct. They have to be free or released from the drum. You can't tell this by the method you used. They could be dragging. Don't mess with the clutch screws. If the car moves in low & high they might be OK. Once your sure the bands are free you must adjust the shift linkage for what's called "Free neutral". I'll try to add the diagram for it here. Understand this: even with everything adjusted properly you still might have a slight forward creep. It's the nature of the beast but it should be SLIGHT! I believe you have a dragging band. Check it out and ask more questions before worrying about warped or broken drums. (sorry. can't figure out the image thing. Go to the MTFCA forum site and search free neutral The diagrams there).
 
Here are the instructions for adjusting for a free neutral.

Or you can put the cotton bands back on, and have some body crank the car while you adjust the bands. That way you can see the drums moving, and when you over tighten them youll know you have gone to far when the drums stop. Always work for me. :rolleyes:
