EZJOB's 7/8" shaft vertical pressure washer pump is a ready-to-install replacement that restores up to 3000 PSI and 2.5 GPM for compatible gas pressure washers.

If your pressure washer shows weak spray, pulsing, or visible leaks, this vertical shaft pump from EZJOB is built to revive performance without complex maintenance. It fits vertical 7/8" shafts and rear-facing ports, arrives pre-filled with oil and key components, and is engineered for gasoline engines in the 180–196cc (6.5–7 hp) range. The pump provides a practical, cost-effective alternative to OEM units for many popular brands when part numbers and dimensions match.

Which machines will this EZJOB pump fit?

Compatibility depends on shaft size, port orientation, mounting pattern and original output specs. This pump targets gas pressure washers with a 7/8" vertical shaft, rear-facing inlet/outlet, and an original output around 2700–3000 PSI.

• Fits engines ~180–196cc (6.5–7 hp) and vertical axial configurations.
• Compatible with many models from Ryobi, Briggs & Stratton, Husky, Craftsman, Homelite, Simpson, Generac, Honda and others (verify model numbers).
• Matches common OEM part numbers listed in the product features — confirm keyway and mounting hole alignment before ordering.

How does installation and startup work?

The pump ships pre-filled with oil and includes a shaft key and necessary fittings for a straightforward swap. Prepare the system by connecting hoses, purging trapped air, and never running the pump dry.

• Includes pre-filled oil — no initial oil change required for the supplied fill.
• Comes with unloader, thermal relief, EZ start valve, M22 outlet and 3/4 NH inlet fittings for typical hose connections.
• Simple mounting: align 7/8" shaft and keyway, secure flange, attach rear ports, then purge air before first run.

What performance and durability should I expect?

This EZJOB pump is rated up to 3000 PSI and 2.5 GPM at about 3400 RPM, restoring high-pressure spray for common cleaning tasks. The housing is fully die-cast aluminum to resist corrosion, and the double-seal system helps prevent leaks during operation.

• Delivers up to 2.5 GPM at 3400 RPM for effective cleaning power.
• Double-seal construction and die-cast aluminum body improve reliability and corrosion resistance.
• Pre-filled oil and sealed design provide roughly 150 hours of initial running time before service considerations.

Are there maintenance or usage tips I should follow?

Although the pump is pre-filled and sealed, observing standard pump care will extend service life. Avoid running dry, drain before freezing temperatures, and check hose connections regularly.

• Always purge air and verify water supply before starting the engine—never run the pump dry.
• Drain the pump if storing in freezing conditions to prevent internal damage.
• Inspect seals and fittings after the first few hours of use to ensure proper seating and no leaks.
