Topic: gears grinding with a new clutch

  I have a 1951 Ford f 2 pickup. I had a new clutch installed and still have gear grinding about 60 percent of the time. The tranny is a 4 speed floor shift, non syncro mesh. Is it necessary to double clutch when shifting? I have tried double clutching and not. does not make any difference. THANKS

  Yes, you will have to double clutch this non-synchro transmission when shifting gears. With practice your shifts will get smoother.

  If your sense is that there is no difference double-clutching or not, it may well be that your new clutch isn't set up correctly and that it is not disengaging completely. It's a somewhat widespread problem these days, especially if the flywheel has be resurfaced.

  you will need to go slow, double clutching is an art. clutch in- go to neutral- clutch out-clutch in go to next gear and release clutch to continue. it took a few days of grinding for me to get used to it in my 41' 1 1/2 ton

  One of the usual problems associated with a non-synchro (crash box) transmissions is a too high idle adjustment. A heavier transmission oil can also help by curbing the difference between the rotating parts and the cluster gear. Most of us old timers learned how to "double clutch". Be sure the adjustment of your new clutch for the correct action, including the free play between the clutch (throwout) bearing and the crutch release arms, is correct. It will change with wear.
