Bring your tired pressure washer back to life with this 7/8 in. vertical-shaft replacement pump, rated for up to 3400 PSI pressure and 2.5 GPM flow - more than enough muscle to blast caked concrete, mossy decks, siding, fencing, and dirt-coated farm equipment. The standard SAE bolt pattern fits most rear-outlet 196-230cc gas-powered pressure washers, including popular Honda, Simpson, RYOBI, Briggs & Stratton, Subaru, and Craftsman compatible models, so swapping out a worn pump is straightforward for both DIY homeowners and Pro landscapers. A maintenance-free crankcase eliminates the chore of changing pump oil, while strengthened plunger hardness improves wear resistance and prolongs the life of the water and oil seals - small details that translate to fewer service calls and longer seasons of clean. Easy cold-start engineering means you do not have to bleed pressure before firing the engine, and the included detergent tank adds a soap-down soft-wash mode for cars, vinyl siding, and patio furniture. Whether you are restoring a neglected pressure washer in the shed or upgrading a tired pump on a daily-driver work tool, this replacement kit is the kind of practical fix that pays for itself by the second job.
