Tool Daily 7/8-inch Shaft Vertical Pressure Washer Pump — 2400–2800 PSI, 2.3 GPM Aluminum

Tool Daily's 7/8" shaft vertical pressure washer pump is a direct-fit replacement pump kit engineered for vertical-shaft gasoline pressure washers, rated 2400–2800 PSI at 2.3 GPM for heavy-duty cleaning.

This replacement pump swaps into vertical gasoline-engine pressure washers when the original pump has worn out or failed. Built from an aluminum-alloy body and fitted with a thermal relief valve and included accessories, the unit is designed to restore strong, consistent water pressure for deck washing, siding cleaning, vehicle detailing, and other outdoor maintenance tasks. Note that this pump is specifically for vertical engines with a 7/8" shaft — it will not fit horizontal-engine models or electric pressure washers.

Will this pump fit my pressure washer?

Compatibility depends on engine orientation and shaft diameter. This pump is made for vertical gasoline engines that use a 7/8" shaft; it will not work with horizontal engines or electric units.

• Requires 7/8" shaft — confirm your old pump shaft size before ordering.
• Designed for vertical-shaft gasoline pressure washers only.
• Commonly compatible with many Generac, Honda, Briggs & Stratton, Troy-Bilt, and Craftsman models — check model fitment lists.

How does performance compare to my original pump?

This pump delivers working pressures between 2400 and 2800 PSI and a flow rate of 2.3 GPM, which aligns with many medium-duty consumer pressure washers. The aluminum-alloy housing balances durability with reduced weight, so you get reliable force without excessive bulk.

• 2400–2800 PSI working pressure for effective grime removal.
• 2.3 GPM flow rate suitable for routine exterior cleaning projects.
• Max operating fluid temperature up to 140°F for warm-water cleaning tasks.

What safety and longevity features are included?

The pump includes a thermal relief valve to prevent overheating and reduce stress on internal parts. It also ships with gaskets, a keyway, and mounting bolts so you can replace the pump with fewer trips to the parts store.

• Built-in thermal relief valve helps protect internal components from heat buildup.
• Aluminum-alloy body resists corrosion and keeps weight down.
• Comprehensive accessory pack (gaskets, flange bolts, keyway) for straightforward installation.

What comes in the package and how easy is installation?

The kit includes the replacement pump plus a set of fittings and hardware meant to simplify swapping units. While many users can complete the changeover with basic tools, having a service manual or referencing a model-specific guide is recommended.

• Included items: pump head, thermal relief valve, chemical injector siphon hose, gaskets, keyway, flange bolts.
• Adapter fittings: M22 14mm and 3/8" quick-disconnect fittings, 3/4" to 1/2" quick connect pieces, and plugs.
• Installation generally requires removal of the old pump, alignment to 7/8" shaft, and reattaching hoses and fittings.

Who is this for: The Tool Daily 7/8" shaft vertical pressure washer pump is aimed at homeowners, landscapers, and maintenance pros who own vertical-shaft gasoline pressure washers and need a reliable replacement pump to restore original cleaning power. Choose this kit if your machine uses a 7/8" shaft and you want an all-in-one replacement with safety features and the fittings required for a typical swap. If your pressure washer uses a horizontal engine or an electric motor, or if your shaft size differs, look for a model matched to those specifications instead.
