504 Shifting Problems

I have a 1966 IH 504. Its getting harder and harder to shift between all gears, I have to really yank on the shifter to get into another gear. Especially between 1rst and reverse. Any ideas.
 
You were faster on the trigger tonight . When it comes to doing it by the book all depends on how much FIELD TESTING it had when new . And with that i am going to the kitchen and fix me my NERVE med's .
 
I agree with the others. We have had a 504 utility with T/A on the farm since new and difficulty shifting it out of gear is a sign of the T/A needing adjustment. I have done it many times. The tractor still has the original T/A and has never been repaired. I always adjust it according to the operator's manual instructions.
 

I think what tractorvet is saying is that there is probably some wear in the linkage, and you should do it by the book, but you need to compensate for that wear at the same time.
 
I bought a set of manuals off e bay but nothing in there about adjusting the TA clutch. Do you know if there is a link or something to the information ?
 
The process (as I do it): Set the clutch free play at 1 inch down from all the way up measured at the foot plate to cast
contact in the pedal arm. this can be felt by hand. In an open area with nothing to run into, use low gear, and measure with
a tape measure, the point that letting up on the pedal causes the tractor to begin to move. this is the engagement point of
the master clutch. The TA linkage is now adjusted so it begins to be released at this position of the foot pedal. further
depressing the pedal releases the TA clutch fully. (usually another 3/4" or so to an inch of foot travel. This assures that
the TA clutch is fully engaged when the master clutch applies power through it. It also assures that the full pedal
depression releases the TA clutch so shifting is not bound up. The lever should apply and fully release the TA clutch very
near the center of its travel. Doing this compensates for linkage wear and I have had no issues doing it this way. Jim
