A friend of mine has a very stiff spring in his clutch. It is quite hard to push into low or neutral and very hard not to pop into high. Is there any way to reduce the tension of that spring?
Tell him to learn to use it as is and to exercise his left leg! And no, not without tearing down the transmission.
That's sad, because he has a bad left ankle. He has no problem with the spring in my car. I have driven his and, yes, it is much stiffer than the spring on any other T I have driven.
Wouldn't backing off the clutch adjusting screws help, as long as the clutch doesn't slip.
See Chapter XIV, page 139 of the Ford Model T service manual, it gives the in-car procedure for changing the high clutch spring.
You would still have to pull the motor foreword or pull the rear end to do the job.
The service manual procedure shows pulling the rear end back and pushing the ball down to get it out of line from the hogshead.
I think we will try adjusting the fingers and if that doesn't do the trick, change the spring. I wonder if he has a watts clutch or a jackrabbit clutch? Have no idea. He bought the car as it now is. I have a couple of standard Ford springs. Maybe one of them would work.
If you decide to do the swap, please be sure to check the load of the spring you take out and compare it to the standard Ford springs and let us know how they compare, thanks!
I wonder if some one has added one of these; https://www.modeltford.com/item/3340SP.aspx
give the spring a little more oomph. Norman; do you know what your spring compression weight is? Ball park is about 90 to 115 LBs when compressed to 2 inches. Adjusting the clutch fingers is not going to change the spring load as it has to be still compressed X amount to remove tension from the fingers. Watts or Jackrabbit, same thing, does not effect the spring tension. The part of easy to pop into high sounds like an adjustment, has too short of a window between low when the band is no longer contacting the drum and high.
Donald gave the right solution.
If it's one of the "original" Watts clutch springs that is "round wound" - too freaking much pressure !
Thanks Steve, it's been so long I had forgotten about the issues with the original Watts clutch spring, thanks for the reminder.
Odd, I use one of the "round wound" Watts springs with my Watts clutch, and I haven't got any problems with a hard pedal?
How long's it been in there Roger ? I replaced a Watts round spring from in a customer's speedster for being "tight" and it actually had worn the brass clutch throw out fork nearly in two from so much pressure against the throw out steel collar ! It had been in there since Watts (from Oregon) came out with his "friction" material clutch packs years ago.
The problem with the Watts clutch was mainly that they would slip off the sliding disc or spring retainer and loose compression.
