Thought I"d treat the Allis to an oil change, all round. What"s the recomended oil grade for engine and gearbox/diff, climate temp range 50-110F.
Our Allis has a single cylinder hydraulic cylinder tpl. Where is the oil supply for that - does it use the diff oil?

for the motor i use 10w-40 engine oil. i just get the generic brand at Wal Mart. For the transmission- hydrauilcs- pto, all are the same cavity. 3 drains under the boxes, one fill by your left foot thru the 1 inch plug. Original was 20 wt motor oil, these days most people use universal hydraulic fluid, HyTrans, or similar hydraulic- transmission fluid from Case, JD, etc.

Changing all the fluid would be a good thing to do as many don't do it. Two places that are always neglected are the oil bath for the rear tires. Locate this by laying under the tractor and by each tire is a plug. I bet the oil hadent been changes in many years on the one I bought. I came out like a thick goo. Took off the covers and cleaned it out real good. The other is not a fluid but a grease zirk that is always missed. Up under the torque tube just behind the engine is a cover (or should be. Look up in there and looking back toward the seat is the throw out bearring that needs grease. It is also the place that you can see the cluch and adjust if needed. Good luck with the job. We're here if you need us.

Tranny hyds. and rear end use the same oil. I use hytran in my Cs and it works well
