IH 454 hydrolics

Mel in KS · Apr 21, 2013

I have a new to me North American made IH 454 diesel with IH 2050 loader. The 3-point arms leak/drop to their lowest level when the tractor is shut off. In changing filters and oils I found the Hydro By-pass Valve and screen to be missing from the hydro filter canister and I hope to replace it. Are these conditions related or is the drop down some other issue I should look for? Thanks for thoughts.

Hi Mel, the 454 Diesel could be assembled in USA but D-179 Diesel engine was made in Neuss Germany, main frame axles/trans/diff/torque tube were made in Doncaster UK.

Re 3pt leaking down could be lift cylinder or 3pt lift control valve leaking. Problem is only a nuisance, must remember to lower 3pt implement before shutting engine off, sometimes hydraulic will jerk up if really bad leak. My brother has 454 that has 3pt leak down for at least 25 years now with no other problems.

The big problems with those models of tractors is the Operator forgets to release the parking brake and drives tractor with parking brake engaged and the parking brake band gets chewed up in the transmission. The bits of chewed up brake band ends up clogging up hydraulic filter and other small hydraulic orifices. Later models have a flashing park brake engaged lamp on the dash.

Thanks for the information Jim. My mistake; assembled vs. made. Seems to be very well designed and made. I hope to give it better care than it has been used to.
