Long story short, this was a loaner E-58H I kept on hand. The thing is, it NEVER got loaned out, not even once. So time for it to go. Meyer moved on from the E-58H a long time ago. I kept it as a spare for my E-58H new plow customers under warranty. Some corrsion on the bottom of the gear pump. One of the nuts on back still has the shipping cap on it. It was on a new Meyer Drive Pro, on a Tacoma, and I swapped a brand new one in place of it as the owner had a lot of trouble with the plow overall. He came in with his pants ripped and his hand bleeding. A month old plow. He could not get the plow to lower. I tried a couple of things and due to time constraints, and how new it was I gave him a new one. Put this on the test stand and all is well. So it became a loaner that never got loaned out. Just drained the M1 fluid and filled with synthetic low temp hydraulic fluid. Put it on the test stand and it is making 1900psi @170 amps. Ready to go to a new home. We offer a kit if you are replacing an E-47, E-57, or E-60 with this H Model. Read on if you are.... You will need THIS coupler kit. The one Meyer offers is wasteful and expensive. We sell what you need to put this in place of what you have now (47, 57, 60). The same Pin Type Couplers will thread into this unit. We include the wiring adapter as well. So (2) Sets of Pin Type Couplers, (2) adapters (assembled with Coupler Set), and 15912 Adapter. Click on Related for it. Scroll lthrough all the images. The first ones were with the run around hose on it to keep it full and sealed. It was removed for the fluid change and testing in the later pics.
