Snow Plow Pump Motor for Boss Skidmore JS Barnes 12V 1.7kW CW Replaces HYD1563 W-8958 Lester 6046

Controller says up. Blade stays down. You cycle it a few times, hear the pump whine, then nothing. On a Boss plow, that is usually the motor, not the pump.

This one bolts in its place. 12 volts, clockwise, and here is the headline: 1.7kW. That is 2.28 horsepower, a step up from the 1.2kW motors most plows run. Boss pumps work hard, lifting and angling a loaded blade hundreds of times a night, and the extra output shows up as snappy response when the oil is cold. Field housing is 114.3mm across, 4.5 inches, overall length 189mm. Shaft is a 15.85mm slotted end. Terminal post is 5/16-24.

Numbers it covers: HYD1563. HYD001563. Prestolite 46-2432, 46-3564, 46-812, MDY6125S, MDY7030, MDY7058. Lester 6046. WAI 6046N. Arrowhead LPL0013. Western W-8958. DB 430-20023. M-2600, E-5622-1, 82-6870, 160-718. Any of those on the label or in the parts book and this is your motor. Fits Boss plows across the board, plus Skidmore equipment and JS Barnes hydraulic power units.

Now the part that saves you a return. Boss used two versions of this motor. The one on this page has a bushing on the drive end. The other version runs a ball bearing there, and the two do not interchange. Look at the end of your old motor before you order. Bushing, you're in the right place. Ball bearing, this is not your part.

Swapping it is straightforward. Two bolts hold the motor to the pump. Move the coupler over, reconnect the cables to the 5/16-24 post, done. No splicing. No adapter plates. Cycle the controller and the blade should move like it did when the truck was new.

What you get: a brand new motor, copper windings, sealed housing against slush and salt. Built in an ISO 9001 and IATF 16949 certified plant, CE marked, twelve months of warranty. The OEM version runs $125 to $225 depending on who's selling it. This one leaves a good chunk of that in your pocket.

In the box: motor x1. Mounting bolts and coupler come off your original unit and get reused.
