Engine Compatibility — What Drives the RRV35G36-PKG

F24 SAE J609a. 1″ Hollow Keyway Shaft. 13–15 HP Range. Predator-Compatible.

The RRV35G36-PKG‘s F24 SAE J609a direct-drive flange accepts a 1″ hollow keyway shaft rated for 13–15 HP gasoline engines. The 3.5 GPM / 3,600 PSI output requires more horsepower than the compact 3.0 GPM sibling — this engine range reflects that demand:

• Harbor Freight Predator 420cc / 13 HP — the primary Predator pairing for the RRV35G36-PKG. Falls at the base of the 13–15 HP compatibility range. Direct value-priced replacement for Honda GX390, Briggs & Stratton XR2100, and Kohler CH440. Compatible with the F24 1″ keyway shaft — the natural choice for contractors building Predator-powered mobile wash rigs and flatbed stations with the RRV35G36-PKG.
• 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 RRV35G36-PKG F24 1″ keyway shaft — the preferred single-cylinder Predator pairing for sustained high-pressure continuous-duty operation.
• Honda GX390 — 389cc, 13 HP, 1″ SAE J609a keyway shaft. The benchmark commercial pressure washer engine in this HP range. Direct-mount compatible with the RRV35G36-PKG F24 flange.
• Briggs & Stratton XR2100 / Vanguard series — 420cc and above, 1″ SAE keyway. Direct-mount compatible within the 13–15 HP range.
• Kohler CH440 / Command series — 429cc, 14 HP, 1″ SAE keyway. Direct-mount compatible with the RRV35G36-PKG F24 flange.
• Compatible 13–15 HP diesel engines — any gas or diesel engine within the 13–15 HP range with a 1″ SAE J609a horizontal keyway shaft at 3,400 RPM is compatible with the RRV35G36-PKG F24 direct-drive flange.

Built for the Predator-Powered Contractor Rig

Balanced Output. Mid-Range Flow. Flatbed Ready. Maximum Value Per Dollar.

• Build your own balanced system — 3.5 GPM at 3,600 PSI — a Predator 420cc / 13 HP paired with the RRV35G36-PKG delivers 12,600 cleaning units of professional output — more flow than the compact 3.0 GPM package, more pressure than lighter-rated alternatives, in a balanced configuration suited for contractors, fleet detail operations, and agricultural wash programs where the mid-range output hits the right specification without oversizing the engine.
• Right-sized for the 13 HP Predator platform — the RRV35G36-PKG’s 13–15 HP engine range is the natural home of the Predator 420cc. Contractors already running Predator 420cc engines on their rigs can spec the RRV35G36-PKG with confidence that the engine is appropriately matched to the pump output — not undersized, not oversized.
• Standardize mid-output stations on a mixed flatbed — contractors running mixed-output flatbed rigs can pair RRV35G36-PKG stations alongside higher or lower output packages, all sharing the same RRV Series rebuild components and the same AR North America parts network. One service call covers every station.
• AR North America national parts network — every wear component in the RRV35G36-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.
