The Multiquip 22901 Honda GX160 Engine is a genuine OEM engine assembly designed for Whiteman and International walk-behind and ride-on power trowel models. This is a direct-replacement engine built to the original configuration, confirmed for use with CA4HM, CA4HC, CA5BC, J36-M30, J3036H55, JS60C, JH90C, JH55C, and CS24H55E series trowels. As a genuine OEM component sourced through Multiquip, part 22901 carries the same specification as the engine installed at the factory. When your trowel engine fails or reaches the end of its service life, replacing it with the correct OEM unit ensures the machine returns to full operating performance without compromise.
Key Features
- Genuine OEM Engine Assembly — Sourced directly through Multiquip, this Honda GX160 unit meets the exact output and displacement specification required by Whiteman power trowel models — not a generic substitute.
- Broad Trowel Series Compatibility — Confirmed fitment across CA4HM, CA4HC, CA5BC, J36-M30, J3036H55, JS60C, JH90C, JH55C, and CS24H55E, covering both walk-behind and ride-on Whiteman and International trowel families.
- Drop-In Engine Replacement — The 22901 matches the original mounting configuration and output shaft arrangement, allowing technicians to swap the engine without custom adaptation or fabrication work.
- Trowel Performance Restored — A correctly rated engine maintains the blade speed and torque delivery that float finishing demands. An underpowered or worn engine causes uneven blade rotation and poor surface results.
- Honda GX160 Dependability — The GX160 is a proven commercial-grade engine widely supported in the field, with readily available service parts and a strong track record on concrete finishing equipment.
The engine is the core power source of a walk-behind or ride-on power trowel, driving the gearbox and blade assembly that floats and finishes concrete surfaces. On trowels fitted with the Honda GX160, the engine must deliver consistent rpm and torque to keep the blades rotating smoothly through wet and curing concrete. When the engine loses compression, develops a fueling fault, or fails outright, the trowel cannot maintain the blade speed required for quality finishing — making a full engine replacement the correct course of action when repair is no longer practical. Replacing with the OEM-specified unit, Multiquip 22901, ensures the drivetrain receives the same power input it was engineered around.
