In process of rebuilding my 26 I replaced the low cam and low notch. After replacing the transmission cover (hogs head), I installed the link and found that when I move the low pedal it applies the low band just fine, but it does not move the clutch lever. I tried adjusting the length of the link and found no improvement. I checked my two other Model T's and found that the lever at the bottom of the pedal on them is 1 1/2 inch from the bendix cover (where it attaches to the hogs head) with the pedal all the way back. My pedal with the new cam and notch has the lever 2 inches back of the bendix cover and the pedal is in about the same position the others are when the parking brake is applied. Furthermore, there is no free play between the position with the pedal all the way back and the application of the low band, which would start to apply the low band as the pedal moved into neutral.
My proposed fix. Remove the hogs head (thank goodness I have not yet installed the engine in the car) remove the pin through the notch and grind off some of the metal on the back side of the notch. I will not grind the side which applies the low band, just the side which will allow the pedal to come back farther.
With the lever in the proper location, the link will move the clutch lever down and put it in neutral, then when the pedal is in the position it now is in, the link will no longer move the clutch lever, but the band will close to put the car in low gear.
Anyway, something else to consider when you are working to achieve a free neutral.
Take the linkage pin out at the high lever.
Pull the low peddle all the way back.
Adjust the linkage in or out to have the pin just slip in with out binding.
Then see what happens.
herm, that's not the problem. Without the pin, the pedal doesn't come back enough.
Norm, I suspect that you may have put the wrong notch (cam?) in. There are two different style notchs...one that goes inside and one that goes outside. I know that putting the wrong notch on the outside will totally throw off the geometry of the affected pedal. Does it nest perfectly with the cam? If not, then that would raise suspicions even more. Good luck.
If you installed a new shaft, some were made too short. They should still give a neutral but it is a short window. Did you try backing off the band? That would give more pedal moment.
Is the clutch release yoke in the correct slot? Is the ring facing the correct way?
The problem is in the pedal. When the pedal is all the way back toward the back of the car, it is about straight up and down. Same position it would be in when the parking brake is on. If you will notice the normal position will put the lever at the bottom forward of straight down. Then when you depress the pedal about an inch or inch and a half, it pushes the clutch lever down into neutral. If you push farther, the clutch lever will not move, but the low band will be applied. In my case, the rod does not move the clutch lever. I think grinding just a little off the notch on the back side, not touching the part which applies low, will allow the pedal to go back enough so that it will operate the clutch lever. Everything on the front side of the notch lines up perfectly and the low band works fine. It is just that the pedal needs to come back farther. I have two other Model T's which work fine and I will grind it so that it lines up the same way as they do. I replaced the shaft, the cam and the notch with parts from Langs and I suspect that maybe the holes were drilled wrong or the notch was not made correctly. Anyway, I am going to try to fit things and will keep you posted as the work progresses.
IT STAYS IN NEUTRAL WHEN IN REVERSE OR LOW. If it goes into neutral and tightens the band for low, except for the position of the pedal sounds like it working as it should. My pedal is now the same after I put the new shaft in but I am not worry and just drive the car.
I recently had a similar problem. Here's how I fixed it:
I think the hole on the low speed notch was drilled just a bit off. Anyway, first I found that pushing the pedal forward locks the low band as it should, so the problem is that the pedal does not come back as far as it should when in the high gear position. Therefore, the lever at the bottom does not push the clutch lever down into neutral. I filed the back side of the notch until I was able to get the pedal to move back to the normal high gear position. Then adjusted the link. I put the hogs head on and tried it. It moved the clutch lever. So I drove in the pin and then put the hogs head on with gasket and sealer.
Today I started the car and it works perfectly in both high and low. The reverse also works.
Anyway, working on a T is not always, "Just bolt on parts". Sometimes they take some fitting.
Norm: Your problem and diagnosis is correct. Some of the replacement low speed notch parts are not correct. I have found the same problem also.
