This pump may require 1/2" spacers when installed, depending on motor configuration. Spacers are used in the case that the pump arm(s) hits the engine or can't reach the under side of frame such as the engine has a longer shaft. If spacers aren't used when installing, the pump legs will break from stress (spacers & longer bolts are NOT included). If not using the new keyway, be sure to transfer the old square key or else the pump will not build pressure

This pump mounts vertical and is a front facing (water inlets/outlets come out of the front of the engine). Pump needs at least 6HP to handle PSI. Pump head can be flipped. Thermal relief valve comes pre-intalled. This is a sealed unit, no oil maintenance required. Please note it is not recommended to run any pressure washer pump above its maximum PSI rating. Doing so can result in damage to the pump (not covered by warranty) and/or serious bodily injury
