Built for homeowners and pros who want a no-fuss pressure washer pump replacement, this 3300 PSI / 3.0 GPM unit drops onto 7/8 in. vertical shaft rear-outlet engines with a standard SAE bolt pattern, fitting most 196-230cc, 6-8 HP gas power plants. The cast aluminum pump body resists corrosion and is rated for up to 150 hours of continuous operation, while the maintenance-free crankcase removes the chore of oil changes so you can keep cleaning siding, fences, decks, driveways, and vehicles instead of servicing your pump. Five quick-connect nozzles let you switch spray patterns for soaping, rinsing, and detail work, and the included siphon tube, shaft keys, washers, and M8 hex bolts and nuts give you the hardware to seat the pump on the first try. With a 3/4 in. NH garden hose inlet, M22 x 1.5-14mm outlet, 6.42 lb. net weight, and a 2600 PSI recommended working pressure, this replacement pump head fits compatible RYOBI, Honda, and Briggs and Stratton style engines without sacrificing flow or pressure. If you have been worried about whether a new pump will line up with your existing motor, the standard SAE bolt pattern and 7/8 in. shaft profile keep installation predictable and the cold-water-only design keeps service life on track.
