But I was an Aircraft Hydraulic mechanic in the military, and have "moonlighted" in that profession for 40 years. I have never heard of a "Earthmaster" hydraulic pump..so I believe that someone else made a pump for the Earthmaster brand. I've got dozens of parts books, for virtually every brand of hydraulic pump ever made,(though I specialized in Vickers) I may be able to help..but you'd have to identify the original make and model of the pump. First.. is it a gear, piston, or vane type of pump ?? [Reply]   [No Email]

Any info on shaft seals for a Hydreco 1512A13B12C7? Email reply might work, depending on rules? Thanks in anticipation [Reply]  [No Email]

I think they also made the pump. The Earthmaster part number is 18318 and the valve part number is 18583. I don't know if the Adel numbers are the same. [Reply]  [No Email]

National--471264-- .625 ID X 1.25 OD X .250 thick. National--470954-- .750 ID X 1.25 OD X .250 thick. One of these seals is slightly thicker than the OEM seal, but it worked fine and moved the wear groove to a different spot on the shaft. Hope this answers your question. Thanks for asking this is what the ERT does. Gene Davis Tennille, Ga. [Reply]  [No Email]
