D17 clutch adjustments, both engine and hand

The power director clutch on my D17 does not stop the transmission. I changed the oil in it last winter, but this did not improve the situation. I've read in the I&T shop manual how to adjust the clearances on this clutch. It looks fairly simple. Could there be some other problem other than needing to make this adjustment?

The bigger problem is the engine clutch. It does not fully disengage. If I've got the engine running beyond just slow idle, I have difficulty shifting. Getting into reverse is very difficult. My opinion is that this is a worn clutch plate and perhaps a need to adjust the release mechanism. This requires splitting the tractor at the torque housing.

Here are several questions. First, could there be some other problem causing the trouble with the engine clutch? If I do need to split the tractor, how much time should I allow to complete the job? My shop is very modest indeed, so it would probably take longer than with a well equipped and arranged shop. Before I wade into this, is there any other problems I might look for or work I might want to do while I've got the tractor split.

Any advice or guidance would be greatly appreciated.

By the way, it is a series I d17.

According to the IT manual, the linkage adjustment does not affect clutch free-play. It simply adjusts the pedal position for operator comfort. The section in the IT manual is very long and I must leave now so don't have the time to study it. I checked the parts manual and it shows no other adjustment. Your analysis may be correct but I can't confirm.

If you have a level concrete floor, a wide front end (wide front makes keeping engine vertical easier) and, an adequate means of support for the front and rear, the clutch replacement can be done in less than four hours with three people. I wouldn't try this one with only one person but I'm sure it has been done.
