So I bought a allis dozer hd11e and it's getting transsmisson/Hydraulic fluid in the engine. Thought it was a seal on the pump so fixed the seal but now I have no steering and it's still putting transmission/ hydraulic fluid in the engine. Before I fixed it the steering clutches ran like a dream. Any help would be awesome.

Which pump? There are two, one for the trans on the torque converter and one on the engine for the steering clutches/brakes. And is the unit a EP?

Have you been on Minnpars website? Go to this catalog and pages 212 up for First type/second type. The steering pump is Engine timing cover mounted and usually ABOVE the trans oil level so ANY air inleakage will cause grief, loss of that pump's seals will put oil in the engine directly.

Thanks, no it's not a ep, it says hd11 e-ag. It's the steering clutch pump that I replaced the seal on. And thanks I will go check out that website.
