Allis "Forty Five" Grader Hydraulics Question

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

I'm looking for information on the hydraulic pumps on the Allis “Forty Five” grader that we've revived. 
The hydraulic pump(s?) are leaking back to the PTO case. I haven't pulled anything yet as it is good enough for ranch use at the moment. 
The grader was made by Allis's Australian plant, so the serial # goes 524/***. Which means comparing what we have to what is in US parts and service manuals to work out what we've got. 
The hydraulic pumps (one for steering, one for the “farmerised” hydraulic wheel lean and moulboard roll, which I'm presuming is the one used for the optional hydraulic moulboard shift) are different from those in US. They're both of the same pattern and size, the steering pump has narrower gears and a relief valve. The parts diagrams aren't much use for detail as they look almost hand drawn in the Australian "45" part book. 
The bigger pump is Hydreco 1512A13B12C7, and was made in Australia. 
I've had no luck here on seals – the best comment was “When you could get them they were expensive and now they're RARS (Rare as rockinghorse - - ). 
Any information you might have would be appreciated, a diagram of what is in the seal assembly would help. 
Thanks in anticipation.

	Steve, Got that and thanks. Will post progress. If necessary we will redesign the pumps and plumming - which currently looks like something by Heath Robinson (Rube Goldberg for US readers).
