Wondering what type of oil you use in a 240 utility transmission and rear end, is it all one type? I have a very leaky seal on my transmission output shaft, it appears to be leaking hydraulic fluid..??
 
I'd get a manual and double check.

My Super A manual says SAE90.
My 140 manual says SAE10 with additives, basically HyTran.

Since the Super C and 240 (even the utility) share the same basic internal transmission and differential designs as the Super A/140, I'd expect that the recommendations would've changed there too.

It's probably leaking because of large amounts of water in the rear end causing the level to be too high.
 
Mac: To start with the tractor transmission-rear end and hydraulic are two separate compartments. Use hytran in the hydraulics and gear oil in transmission-rear end. Forget about what Kirsch's manual says, mine says the same yet we all use gear oil in those little transmissions. If we didn't, we'd grind a lb. of gear steel everyday.

Your tractors transmission is probably overfull, 65% of transmission-rear end seal leaks are caused by too much oil in there. Usually it is a mixture of gear oil and water, because these tractors leak more water down the gear shift lever than down the stack if both are left uncovered in the rain. Put a bucket over the gear shift lever. If it's just overnight don't worry about the stack.
 
Yep Hugh. IH even recommends HY-Tran for the older tractors now days but it is no good in them. Gear oil is the way to go.
