Simpson OEM Technologies 90026 Vertical Axial Cam Pump Kit
When the pump on your gas pressure washer wears out, the Simpson OEM Technologies 90026 gets it spraying like new. This fully plumbed vertical axial cam pump kit is rated for 3000 PSI at 2.5 GPM (OEM rating up to 3100 PSI at 2.4 GPM) and bolts onto vertical-shaft engines with a 7/8-inch shaft, such as the Honda GCV160 and GCV170. It is a direct, ready-to-run replacement so you can rebuild your machine instead of buying a whole new unit.
Built for
- Gas pressure washers with a vertical engine and 7/8-inch shaft
- Honda GCV160 and GCV170 class engines
- Owners rebuilding a 3000 PSI class washer rather than replacing it
Why it lasts
The 90026 uses stainless steel pistons for longer seal life and high-performance double high-pressure seals to hold pressure under hard use. A maintenance-free crankcase means you never change the oil, and the fully anodized die-cast aluminum housing resists corrosion. The integrated stainless unloader with an easy-start system reduces pull-start effort. It carries a one-year limited warranty.
What is included
The kit ships with the pump, a siphon tube with filter, mounting bolts, shaft key, and an instruction booklet. Connections include a standard garden hose inlet and a threaded M22 male high-pressure outlet.
Frequently asked questions
Will the 90026 fit my pressure washer?
It fits vertical-shaft gas engines with a 7/8-inch shaft, such as the Honda GCV160 and GCV170. Confirm your engine shaft is vertical and 7/8-inch before ordering.
What pressure and flow does it deliver?

Do I need to add oil to the crankcase?
No. The 90026 has a maintenance-free crankcase, so there is no oil to change over the life of the pump.
