IH 504 Question + Advice needed BADLY

[used red MN]

There are operators and service manuals available on Ebay. Some are in CD format. Get one, it will make life more pleasant. My uncle had a 504 row crop, 1964 I think, it was a nice tractor. I managed to find a 1/16 die cast replica of it about twelve years ago.

Jim, per a PM she has manuals.

Thanks so much! So far it seems the hydraulic reservoir is 12gal. So I’d need 3 5gallon of HyTran? I found this alternative that says for use in Case/IH hytran that’s half the price of the IH branded HyTran. Thoughts? It’s
“Providence Automotive Premium Trans-Hydraulic Fluid for Case / IH 5.0G - PA-IH5HY” sold by Rural King.

Once I drain hydraulic fluid is there something I should do to flush the rest of the bad fluid out?

Thank you!

It’s been a while but don’t think their is anything special (no wet clutches or brakes) about a standard 5 speed trans and ta setup on a 504 so any quality trans/hydraulic fluid will work. You could even use dextron transmission fluid but would contaminate any tractor you shared hydraulic implements with

Getting the water out of the trans is a job as everything inside the trans doesn’t completely drain . The nooks and crannies can hold more than you think.

also the small displacement higher rpm engine didn’t provide the pulling power of the good old farmall m. But it was nicer to drive and had good hydraulics.
