D14 Hydraulic, transmission oil

I finally have the tractor running. The clutch was rusted to the transmission shaft, so I had the tractor split, and the clutch replaced (removed with a torch). It cost more than I like, but was completed in a couple days. the shop even picked up the tractor, fixed it, and brought it back to the farm.

Many folks use a good grade of hydraulic fluid for the hydraulic system. Allis speced out 20 weight non detergent and hydraulic fluid is about the same viscosity. I use 30W non detergent with excellent results in both my D-14 and D-17. The power director also calls for 20W non detergent. I've never had to add fluid to the power director so I don't know if there would be an adverse effect in using 30W or hydraulic fluid. I would think you would be safe with 30W but if you live in the far northern US, it may a bit stiff in the winter. I would not suggest motor oil which has detergent. The power steering also calls for 20W non detergent oil. Detergent oil (motor oil) in the power steering will cause foaming and a mess.

The transmission calls for 90W gear oil. It is hard to find but again I've had excellent results with 85W-130W gear oil which is a multi viscosity gear oil.

I was thinking about using synthetic outboard low end lube for the final drives. I have used it in worn out lawn mower engines to reduce oil consumption. It seems to work well for the last couple years. I may try it in the final drives.

Thank you for all of your help

Final question, what do people do to keep the clutch from freezing to the pres plate? I had to have the clutch plate cut off to get the thing changed. Dont want to do that again.

Thanks in advance.

I have a sticking problem on my 8N Ford. I just put a cinder block on the pedal a few hours before use. After a few hours it releases and works fine. Some leave the cinder block on all the time. Try a few hours and if it doesn't do the trick, leave it on there all the time. It is a problem caused by the clutch disk itself and a new disk may solve it. The one on my 8N looks like new but it sticks after sitting for a while.

Thanks for the clutch advice. I guess the idea is to disengage the clutch so it dosent stick to the pplate.

Thanks for the information
