The Multiquip 42602-04 is a genuine OEM Fuel Pump for the Hatz 4H50TIC engine, designed for HTX6H and STX6H Whiteman ride-on power trowels. As a direct Multiquip OEM part, 42602-04 is manufactured to the exact specifications required by the Hatz 4H50TIC engine, ensuring consistent fuel delivery and dependable operation on the finishing floor. This part is a confirmed fitment for both the HTX6H heavy-duty hydrostatic trowel and the STX6H super-sized hydrostatic trowel. Sourced directly through authorized distribution, you can order with confidence knowing you are receiving the correct part for your machine.
Key Features
- Genuine OEM Fuel Delivery Precision — Engineered to exact Hatz 4H50TIC engine tolerances, ensuring correct flow rate and pressure for consistent combustion performance.
- Direct-Mount Replacement — Matches the original mounting configuration on the Hatz 4H50TIC engine, allowing straightforward installation without adaptation.
- Confirmed Fitment for HTX6H and STX6H — Verified for Whiteman heavy-duty and super-sized hydrostatic ride-on trowel models powered by the Hatz 4H50TIC engine.
- Sustained Engine Performance — A properly functioning fuel pump keeps the Hatz engine running at full power through long finishing runs; a failing pump causes hard starts, rough idling, and loss of hydraulic drive response.
- Fuel System Integrity — OEM construction materials resist fuel degradation and maintain sealed connections, reducing the risk of leaks in a high-vibration trowel application.
The fuel pump is responsible for drawing fuel from the tank and delivering it to the engine at the correct pressure and volume for combustion. On the Hatz 4H50TIC engine fitted to these hydrostatic ride-on trowels, the pump must operate reliably under continuous load conditions to sustain the hydraulic systems that control both blade pitch and machine drive. When the fuel pump weakens or fails, the engine may struggle to start, run erratically under load, or stall — directly interrupting concrete finishing operations and risking surface defects in time-sensitive pours.
