The Multiquip 42602-85 Fuel Injection Pump HTX6H is a genuine OEM component designed for the HTX6H heavy-duty hydrostatic ride-on power trowel. Sourced directly from Multiquip, this pump meets the exact specifications required to restore proper fuel delivery and engine performance on HTX6H equipment. When the original pump wears or fails, swapping in the correct OEM replacement ensures the engine receives consistent, metered fuel flow — keeping your finishing operation running at full capacity. Confirm your model code against your machine's serial plate before ordering to ensure a direct application match.
Key Features
- OEM-Matched Fuel Metering Precision — Genuine Multiquip construction ensures the pump delivers fuel at the correct pressure and timing calibration required by the HTX6H engine, avoiding the rough running and power loss that come with an out-of-spec unit.
- Direct-Swap Installation — Engineered to the same mounting configuration and port dimensions as the original, so this pump connects to existing fuel and injection lines without reworking fittings or brackets.
- HTX6H Application Specific — Confirmed fitment for the HTX6H heavy-duty hydrostatic ride-on trowel, so you can order with confidence that this is the correct pump for that platform.
- Sustained Blade Speed Consistency — A properly functioning injection pump maintains the steady engine output the HTX6H hydraulic system depends on to hold consistent blade pitch and forward drive — critical during large-slab finishing passes.
- Fuel System Integrity — Using the correct OEM injection pump prevents unmetered fuel delivery that can foul injectors, accelerate internal engine wear, or cause erratic RPM behavior during troweling operations.
The fuel injection pump is responsible for drawing diesel fuel from the tank and delivering it to the engine's injectors at precisely controlled pressure and volume. On a hydraulically driven ride-on trowel like the HTX6H, consistent engine output is essential — the hydraulic system that drives both the blade pitch and the machine's travel depends on steady RPM and torque. When an injection pump wears out, symptoms typically include hard starting, loss of power under load, uneven idle, and increased exhaust smoke, all of which compromise finishing quality and can lead to broader engine damage if left unaddressed.
