Difficult Shifting

BUT you noted that you have a hang up with the TA in either position which leads to other possibilities also. I have personally seen where the original full faced fiber clutch disk (main clutch) has been replaced with a metallic button clutch disk. These button clutches were sold on the premise that they reduced the heat created by a slipping fiber disk and that they could handle higher horsepower better in hard use situations like under loaders. What I have noted is that these clutch disks are harder than the flywheels and pressure plates and wear a curve into the pressure plate and flywheel surfaces. Tearing the clutch apart and installing a new disk, pressure plate, and resurfacing the flywheel will cure the issues for a while unless you put a full faced fiber clutch back in. I have theorized that this curved area causes the clutch to “drag” when released and even may get “sucked” against either the pressure plate or flywheel. Some have had some reduction in this phenomenon by grinding an X shape in each pad on the clutch disk.

I usually put up with poor shifting until I have the tractor apart for another reason, then I reface the flywheel, replace the pressure plate and the clutch disk with the original style full faced fiber disk. This seems to offer the best solution when adjusting the TA won’t take care of this problem.

My nickels worth.

The principle here is quite simple. Many guys report they cant shift gears until they pull back on TA lever. Technically what that short linkage does is shift TA to low as you push clutch pedal in. So rather than having to pull TA lever each time you adjust so clutch pedal does it all. Truth is none of the older Farmalls will shift easy when TA is technically still in high.
