According to the service manual the D14 transmission takes 16qt of EP 80 and the clutch takes 10qt of SAE 20w. I bought these lubricants and began to change. I drained the transmission and noticed that it also drained the clutch compartment. How do you put different weight oils in each if they evidently join together?

If both compartments drained when you drained the transmission, that means the seals between the power director housing and the transmission housing are bad. The seals on both the main shaft and PTO will need to be changed. There are 2 seals back to back on each shaft. I replaced all 4 in my D-14 about 7-8 years ago. I don't remember for sure, but I think you can change the seals by splitting the tractor between the power director housing and transmission housing. If you are going to tackle this yourself, get an I-T manual or a reprint of the Allis Chalmers service manual from Sandy Lake Implement (they advertise on here). Don't be afraid to ask questions on here. There are alot of knowledgable people on here who offer good advice free of charge!

Jason, will it damage anything to fill compartments back with the EP 80 fluid I bought and run it temporarily until I fix it?

I would use a hytran fluid(basically a 20wt oil) in the whole thing. My WD45 has been that way since I replaced 3ed gear in it 28 years ago. The hytran will work just fine in the transmission and differential but 80 wt might be a little thick in the PD and hydraulics, unless you keep the tractor in a heated garage all winter. The only problem I have is there are a couple gaskets that need replaced and 20 wt will seep through easier than gear lube. Charlie

okay, thanks a lot. Just didn't want to damage anything. I'll do that until I decide what I want to do with it! Mark

I agree with Charlie. Put Hydraulic Transmission Fluid in both compartments. I use CaseIH HyTran Fluid. I would not do any really hard work with it until you get it fixed. It wasn't designed to be run with HyTran in the transmission and I don't think the hydraulic pump or power director would like 80 wt gear lube You will definetly find out how good your gaskets, axle seals, and PTO shaft seal are.

Jason, I have plowed with my 45 and even pulled a sled once in a tractor pull. I don't think you can hurt a transmission using it since it is used in the high HP tractors of today without any problems.

From what I've heard there are a few people that use the universal hydraulic/transmission fluid everywhere including in the transmission. I put 80-90W gear lube in the transmission because I split my tractor apart and replaced the seals on the upper and lower pinion shaft. That being said I wouldn't be scared to run the universal fluid everywhere without being worried about the transmission.

Think for yourself and be your own expert. Be willing to change your mind; however, willingness to change your mind doesn’t mean that you will. Blindly following any path is the pinnacle of insanity.

Rodger, gear oils are confusing as they are rated on a different scale. 20W hytran is equivalent to 70/75W gear oil in viscosity and includes the necessary high pressure additives (20w engine oil does not)
