The Multiquip 42612 Fixed Pump 19 CC and 8 CC Gear Charge is a genuine OEM hydraulic pump assembly designed for the HTX6H and STX6H hydrostatic ride-on power trowels. As a direct Multiquip OEM component, 42612 is manufactured to the exact specifications required to maintain proper hydraulic system operation on these machines. This pump is a critical drive-system part, and sourcing the correct OEM replacement ensures your trowel performs the way it was engineered to from day one. DHS Equipment stocks this part to keep your finishing crew moving without extended wait times.
Key Features
- Genuine OEM Hydraulic Specification — Matched to the precise 19 CC fixed displacement and 8 CC gear charge volumes required by the HTX6H and STX6H hydraulic circuits, ensuring correct system pressure and flow output.
- Direct-Fit Replacement — Engineered as a bolt-in replacement for the original pump assembly; mounts and ports align to the existing hydraulic plumbing without modification.
- Confirmed Fitment for HTX6H and STX6H — Validated for Multiquip heavy-duty hydrostatic ride-on trowel models HTX6H and STX6H, covering Hatz diesel-powered finishing machines in this series.
- Sustained Blade and Drive Control — A correctly functioning fixed pump maintains consistent hydraulic pressure to the blade pitch and drive circuits, enabling smooth, controlled finishing passes across large concrete slabs.
- Verified Multiquip Part Number — Sold under the exact OEM part number 42612, eliminating cross-reference guesswork and reducing the risk of receiving an incompatible pump.
The fixed pump on a hydrostatic ride-on trowel is the heart of the machine's hydraulic system. It delivers pressurized hydraulic fluid at a fixed displacement to drive both the blade pitch control and the machine's propulsion circuit, giving the operator precise command over speed and finishing angle. When this pump wears or fails, the trowel loses hydraulic pressure, resulting in sluggish or unresponsive blade adjustment and reduced drive performance — both of which compromise finish quality and operator control on a live concrete pour.
