Hydraulic oil

Postby Snuffdipper » Mon Oct 12, 2020 2:10 am

I’m gonna rebuild my touch control unit and pump today. Can I use delo 15w40 motor oil in the touch control as hydraulic oil? I’ve heard of the hydro pump leaking into the crankcase so was wondering if I could just use the same oil in both so if it ever leaked into engine it would all be the same oil. Thanks

You can, since that was the question. But shouldn't.

Use Hytran compatible hydraulic oil.

ISO 32 hydraulic oil is equivalent to SAE 10 weight engine oil.
I have an excuse. CRS.

Besides, if your hydro unit/pump leaks into your engine, then you're engine's oil level is overfull and your hydro unit is below what it should be to operate properly.

Use hydro fluid (Hy-Tran or other as Eugene stated) in the Touch Control and engine oil in the engine. And seal the leak if one is found. Tractor Supply has their house brand hydraulic fluid which is what I use.

Hi,
15W-40 motor oil is too thick for the Touch Control, it is supposed to have thin hydraulic fluid.
Case IH Hy-Tran fluid is thin. :)

Well I rebuilt my hydraulic pump and box today. Found out why hydraulics didn’t work. Pulled pump off and the gear was inside tractor so it fell off the pump. I took oil pan off to make sure pump gear nut wasn’t in the pan and it wasn’t. Can’t find it anywhere. So I’m guessing whoever had pump off before forgot to put the stupid nut back on. So I’ll order new pan gasket put it back together and start it up. Hydros should work now. I’ll keep you updated

Did you find the tabbed lock washer that keeps the nut from loosening?

No was just the gear inside. Never found nothing else. The kit came with new nut but not a tab lock washer so I just put red lock tight on the threads and impacted the nut on. Shouldn’t come off. Hope not anyways

Hi,
The pump gear nut originally uses a lock washer that you bend part of it over 1 flat of the nut, to lock it on the shaft.

Below is a listing at TM Tractor for the lock washer.

Below is a pic from TM Tractor of the lock washer in position. :)

I would highly recommend getting the correct tabbed washer to lock the gear and nut on. Locktite is great for nuts and bolts subject to vibration but not so good for rotational forces

Ok I’ll call Paige tractor here in tx. I’m sure they have one in stock or they can order me one. They will get it faster than I can but pretty sure they’ll have one in stock. They’re only like 30 min away from my house
