I am still having power problems with the Swamp Fox. Today I noticed when I push and pull the drive belt to get the top and bottom of the belts to come together in the middle (like you are checking belt slack) the driver clutch that is attached to the shaft on the T20 will move which seems to be all the way open. To me this does not seem right. The Fox will move but I have high RPM's and no speed. Could this be a keyway problem?
Thanks
I take what you said to mean that when you squeeze the belt, the clutch opens up (movable sheve, moves toward the t-20). if that's the case, I suspect that your clutch spring has broken.

Thank you for your response. That is exactly what it does. I pulled off the clutch to check the key and that is good. I will check the spring it may be a good time to get the new red spring.Originally Posted by racerone3
PS. I have a 1974 uncut Bronco.
you might have just lost the snap ring from the back of the clutch... if the snap ring that keeps the helix on the clutch is in tact, then it's your spring. if you have to get a new one anyway, then it's the perfect time to upgrade to the red spring. i've never tried one, but i would like to change one of my machines out one of these days and see how I like it.
uncut broncos are getting real hard to come by! mine is a 71 sport. the po welded in 1/4" plate as a replacement to the rotted floor boards, but otherwise there has been nothing done to mine that couldn't be put back to stock very easily. as much as I hate to do it, i fear the Bronco might have to be the next toy to go up for sale

The green spring that was in the clutch of the Swamp Fox was in pretty bad shape too. The new red spring makes a world of difference in low end grunt. You can feel the power building and when the shift takes place. I think other than a racer, the red spring is the way to go on an amphib.
At one time I had an uncut '74 Bronco, lime green, straight 6 200 c.i., three on the tree. It had alot of style though. I put dual headers on it and by the noice you would have thought it was a 351 Cleveland. I miss the old Bronco. Have a '78 I.H. Scout 2 thats tricked out and will have that until my last days.
I am going to order a new spring on Monday and hope that fixes the problem. When I bought my Bronco my plans were to cut it and paint it lime green but then I decided to restore it. It has a 302 three on the tree. From what I read about replacing the springs a lot of the job is getting the clutch off the transmission. On the Swamp Fox it is one bolt and I had it off. I hope the rest goes smooth and it fixes the problem.
