The PTO is lubed by transmission oil. Hydraulic oil can leak into the transmission through the seal between the trans and hyd. reservoir. Early tractors had one seal
here, later ones had two, one facing in each way. There is a kit to install the double seal in early tractors. You can't just put two in early tractors the parts are a
little different. You have to split the tractor to do this of course. The hydraulic oil level is higher than the trans oil level so oil will tend to leak towards the
transmission from the higher hydraulic level. You don't say which clutch is dragging. If it is the hand clutch which runs in the transmission oil some dragging is normal.
To adjust you add or remove shims from the clutch. It is under the cover under the battery. You need a manual but basically you adjust (with shims) to get a reasonable
snap on disengaging/engaging. You don't have to set it so it is hard to work, an light/easy lever action is about right. If it is the foot clutch (engine clutch) it is a
"standard" type dry clutch and you adjust the free play with the pedal linkage so you have about 1" of "free play". I have seen the springs in the center hub of clutches
break and small pieces fall out and cause the clutch to not release at times. If this is happening you may see pieces of coil spring in the bottom of the clutch housing
under the clutch.
 
Thanks for the reply. I do believe the seal is leaking between the Hydraulics and transmission. Fluid comes out of my fuller plugs on both transmission and rear end. I dont believe hydraulic fluid will hurt anything??
The adjustment is needed on my engine clutch. Ill look tomorrow for a way to adjust the clutch pedal. I have only looked at the clutch shaft for adjustment there. And there is none on that clutch shaft. Any adjustment on the clutch itself? Ill open the inspection plate tomorrow, and look for spring parts etc.
 
You need a certain clearance on the clutch fingers. If memory serves, it's 1/4". You can access it from below but it's pretty tight.
