4430 steering pump leak

[Dw King]

I’m working on a 4430. The steering pump is leaking oil at the plug on the side of the steering pump. I have removed the side rail, plate in front of the plug and the snap ring retaining the plug. The plug is being very hard to get out. I screwed the bolt into the plug and thought I could use it as a puller to get it started out but am afraid I’m going to strip the thread in the plug. The plug will move a fraction but stops! Anyone have any suggestions on a puller or any other advice on removing this? I believe Deere calls it a sleeve?

That plug should have an o-ring & backup washer on it. I'll suggest attaching a slide hammer to threaded hole in the plug & bump plug out of the bore

Loosen the oil line going to that end of the piston. Hydraulic suction will prevent pulling the plug out. Have also seen the snap ring roll a burr on the edge of the bore. Slide hammer is the best option.
