Model T Ford Forum: Forum 2013: Gear Problem- Car doesn't move?

I had an odd experience and wanted to put it to the Fordians here- I have a 1927 T and I have been having issues setting the Kevlar Bands just right, wants to creep badly and so I re-adjusted the band so when I go from low to high gear it picks up the gear smoothly- got that set.

The new issue is this- when the car is setting still and idling with the hand-brake in the neutral sweet spot, I cannot move the car in reverse by depressing the pedal. The band engages, as I can hear it, but the car will only back-up when I move the hand-brake all the way forward. Any ideas? Seems odd.

Thanks,
Jim

Readjust parking brakes.

Actually, when the car is off and the hand-brake is pulled it won't hold until I am on the last tooth- so that shouldn't be it.

Jim,
Are you sure you have all the bands and clutch adjusted correctly? If the brakes are free then the difference between the neutral hand brake position and how you hold your foot on the left peddle must be different. With the floor boards removed look closely at the clutch lever and peddle positions to see what is different.

First thing to do is remove the clevis pins from the hand brake so that when the lever is pulled it is always in neutral. Now with the engine warmed up, the car should not creep forward or backward in neutral. If it does, you have either the bands too tight or the clutch adjustment wrong. Once you get the neutral adjusted and the bands correctly set, then connect the hand brake.

I would have thought that maybe the transmission brake is out of adjustment, but since it will move with the hand brake all the way forward, it sounds more like a neutral problem.

The only thing which changes when you pull the brake into neutral is the low pedal goes down part way and disengages the clutch. It could be moving too far and applying the low band. Maybe the bolt on the clutch lever out of adjustment. Try backing it out a little and see if that will fix your problem.

All three bands should go down far enough that the pedal comes almost to the floorboard before the band tightens. About one inch above the floorboard. Sometimes if you have wear on the cams in the hogs head or if one or more of the pedals are bent, the band is still too tight even at one inch above the floorboard. If so try removing the floorboard and then loosening the bands to where it will have a free neutral but still move when you push the pedals. If that point is below the floorboard, you have a problem with cams and or bent pedals.

"Maybe the *bolt on the clutch lever out of adjustment. Try backing it out a little and see if that will fix your problem."

*Approximately what is the amount of bolt that should extent below the clutch lever?

I never though of that issue.

The simple answer is "Far enough to put it into neutral".:-) There's not really a measurement, per se, on the bolt. The service manual says to adjust it such that when you pull the lever back, the clutch pedal goes down 1-3/4".

As to the 1-3/4 inch on the clutch pedal. It all depends on how much wear is on the link or the clevis. The bolt needs to be in far enough to raise the clutch lever on the side of the hogs head just enough to put it into free neutral. No more.

I have it now- backed the bolt off about 1 1/2 turns and she is right on- many thanks! This is a very helpful forum!

Their nomenclature for the clevis adjustment is lousy.
"Adjust yoke to have a 1/16" PLAY"?
That's not "play".......that's roughly a half hole short which is much easier to understand.
