574 IH Transmission

Gazz · Jan 29, 2017

I have recently purchased a 574 IH tractor, after servicing and checking over I found the main transmission cracked, before I go any further I have a (Unserviceable) 584 but has a good transmission. My question obviously is will the 584 transmission fit the 574, the 584 is fully synchromesh and the 574 only partial synchromesh, but housings look the same, and I have to find out why the torque amplifier on the 584 does not work, suggestions please!

With the T/A the first thing to check after testing by putting it in torque and applying brake is. Did it stop and make a noise? If it kept going the adjustment may be just off. The older tractors you
could leave them in direct and use them for a long time before repair as usually the spraque clutch failed from free wheeling. We only had the 574 so I do not know how the 584 works. If you have it split
to put the motor in your half way to replacing the T/A. Try adjusting the t/a first if the motor will move the tractor; but if it is dead testing the T/A clutch by turning the engine backwards in direct
doesn't always prove if it is good if this has a hydraulic T/A It will keep you from turn the engine backwards very far). Again I have very little experience with that series. Always like the 574 when we
had it.
