Engine Compatibility — What Drives the SXMV4G40-PKG

F24 SAE J609a. 1″ Hollow Keyway Shaft. Predator-Compatible. Broad Engine Range.

The SXMV4G40-PKG‘s F24 SAE J609a direct-drive flange accepts a 1″ hollow keyway shaft. At 4,000 PSI and 4.0 GPM, engine horsepower is critical — the right pairing protects both engine and pump at continuous operating pressure. Confirmed compatible platforms include:

• Harbor Freight Predator 420cc / 13 HP — widely used in contractor builds and micro-OEM pressure wash systems. Direct value-priced replacement for Honda GX390, Briggs & Stratton XR2100, and Kohler CH440. Compatible with the SXMV4G40-PKG F24 1″ keyway shaft — confirm engine HP is appropriate for your intended duty cycle at 4,000 PSI before building.
• Harbor Freight Predator 459cc / 15.8 HP Max Performance — up to 10% more torque than the standard 420cc. Direct replacement for Honda GX390, Briggs & Stratton XR2100, and Kohler CH440. Compatible with the SXMV4G40-PKG F24 1″ keyway shaft — the preferred single-cylinder Predator pairing for sustained high-pressure continuous-duty operation.
• Harbor Freight Predator 670cc / 22 HP V-Twin — the preferred Predator pairing for sustained 4,000 PSI continuous-duty operation on contractor flatbed rigs and fleet wash installations. Replaces Honda GX630/660/690 and Briggs & Stratton Vanguard at substantial cost savings. The Predator 670cc delivers the overhead needed to keep the SXMV4G40-PKG running at rated pressure across full-day commercial cleaning programs.
• Honda GX390 — 389cc, 1″ SAE J609a keyway shaft. Direct-mount compatible with the SXMV4G40-PKG F24 flange.

• Kohler CH440 / Command series — 429cc, 1″ SAE keyway. Direct-mount compatible.
• Compatible diesel engines — any gas or diesel engine with a 1″ SAE J609a horizontal keyway shaft at 3,400 RPM and sufficient horsepower for 4,000 PSI operation is compatible with the SXMV4G40-PKG F24 direct-drive flange.

Built for the Predator-Powered Contractor Rig

Flatbed Build. Multi-Unit. Maximum Output Per Dollar Invested.

• Build your own system — own the savings and the quality — a Predator 670cc paired with the SXMV4G40-PKG delivers 16,000 cleaning units of sustained commercial output at a fraction of the cost of a comparable OEM-assembled pressure washer. The contractor who builds their own system specifies the components, controls the quality, and keeps the margin.
• Standardize your flatbed for maximum uptime — contractors running multiple identical Predator/SXMV4G40-PKG stations on a flatbed pickup or trailer gain standardized parts, standardized procedures, and standardized performance across every unit. One rebuild kit serves every pump on the rig.
• AR North America national parts network — every wear component in the SXMV4G40-PKG is stocked through AR North America’s domestic distribution. Rebuild kits, packing kits, valve assemblies, C2 unloader service parts — available nationally. The rig keeps running.
• SXMV reinforced platform for high-demand rigs — contractors who push their equipment hardest benefit from the SXMV Series’ strengthened construction. At 4,000 PSI across multiple daily cleaning programs, the reinforced XMV platform delivers the durability margin that keeps production schedules intact.

93% Volumetric Efficiency and Dual Redundant Packing — Why This Pump Runs Longer

More Output Per HP. Less Heat Under Load. Extended Service Intervals.

• 93% volumetric efficiency at 4,000 PSI — the SXMV4G40-PKG’s precision internal hydraulic design transfers approximately 93% of engine input energy into usable water flow at the outlet. At 4,000 PSI, efficiency directly impacts operating temperature — a more efficient pump runs cooler, extending ceramic plunger life, packing life, and valve seat life across high-demand commercial duty cycles.
• Dual redundant packing system — two independent sealing stages on each plunger deliver twice the sealing protection of single-stage designs. Extended service intervals and reduced leakage risk across the stop-start cycles of contractor and fleet cleaning operations at 4,000 PSI.
• Thermal relief protection — built-in thermal relief safeguards protect the SXMV4G40-PKG pump head from overheating during extended bypass periods, increasing seal life and preventing heat damage during idle intervals common in mobile wash operations.
• Oversized crankshaft bearings — stabilize the drivetrain at 3,400 RPM, reducing wear and vibration across long daily duty cycles on contractor rigs and fleet wash systems. Accessible valve caps allow rapid servicing and on-site rebuilds without removing the pump from the frame.
