I'm thinking they are different than standard cast centers .I'd go with steel disc wheels you'd have to change tire sizes but since your replacing tires its cheaper

That seal in similar to the one on the input shaft on the pump they are a two piece ring a special tool is nice But i have put them in with other means and had no problem too get the housing very clean and shaft too use clean oil on the O-Rings and it will slip right in with out any problem then install snap ring

The AHC control can be turned off to check that

I would be pulling the header raise valve out and inspecting all the parts and poppet valves seats and springs

My 1460 does that also when you turn the steering wheel makes it kinda tough when hooking up to a header in tight places because you have to keep lowering the feeder house all the time , I think it is getting feedback thru the steering return somehow it only does it when there's no weight on the feeder house thou

Is the head on it also

Lots of things to check first oil condition , fill level , filter condition , does the other hydraulics work ok? check for a hard turning spindle or bad pivot bearing then check pressure maybe weak pump also

All you'll find for it is reliance engine parts

Alternator crapped out but do a voltmeter check also

I usually pull those switches out of a savage combine

Spray them with penatrating fluid and get tough on them they will either twist off or shut off

We still run a 7720 JD every year along with the newer machines its rock solid reliable Bin sample so clean on soybeans or wheat you can almost plant it so no complaints from me on those combines

Those bolt on fingers things are a joke , I updated headers years ago to full finger retractable fingers and that made a difference of day and night

This is what they eventually look like

I've had three of the splined couplers strip out thru the years you'll know when that happens it make a loud grinding noise and usually requires a new hydro shaft as well
