Calling Greygoat
I saw your list of hydraulic credentials on an “Orphans/Earthmaster hydraulic pump” thread, and hope you might have some information on the 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.
The bigger pump is Hydreco 1512A12B13C7, 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.
Thanks in anticipation.
