Cub149, Thanks for the measurements. I'll check the flywheel depth in the morning.
Jim's comment about the clutch pedal having to move the T/A crossshaft as much as the lever got me thinking and the cartoon light bulb over my head started to glow.
The tractor came with the modified T/A crossshaft shown on the right in the picture above. I replaced it because it looked like a broken part that had been improperly repaired.
Calculating the tangent of the angle that the modified shaft would turn using the motion of the clutch pedal gave the same amount of rotation as using the T/A lever. The shorter arm equals more rotation and more lift at the pressure plate.
I have not reinstalled the modified crossshaft yet because there seems to be an underlying problem that is not found on other 300s, or 350s (or SHTAs) that should be fixed...
To check if the T/A clutch was slipping due to the shimming, I hooked up a field cultivator and ripped up a patch of quackgrass while pulling up hill. The load was enough to stall out the tractor. Rather than use the T/A I pushed in the clutch, let the rpm recover and let the clutch out again. After about half an hour of this the T/A clutch temperature was 86 degrees F.
I think that the T/A clutch clamping pressure is adequate for the amount of power this tractor is making.
