The Multiquip 42602-02 is a genuine OEM PTO Hatz 4H50TIC Flywheel designed for the STX6H and HTX6H hydrostatic ride-on power trowels. As a direct Multiquip OEM component, 42602-02 is manufactured to the exact tolerances required by the Hatz 4H50TIC diesel engine powering these machines. Confirm your model code against the STX6H and HTX6H fitment before ordering to ensure a direct installation match. DHS Equipment stocks this part to help keep your finishing equipment operating at full capacity.
Key Features
- Genuine OEM Flywheel Interface Integrity — Manufactured to Multiquip OEM specification, this flywheel PTO maintains the exact mass balance and bolt-pattern alignment that the Hatz 4H50TIC engine demands for smooth power transfer.
- Direct-Mount Fitment — Engineered as a direct replacement for the STX6H and HTX6H, this component installs directly onto the Hatz 4H50TIC engine without machining or adaptation.
- Confirmed Compatibility — Verified fitment for Multiquip STX6H and HTX6H hydrostatic ride-on power trowel models.
- Consistent Blade Drive Performance — A sound flywheel PTO delivers steady rotational energy to the hydraulic drive system; a worn or damaged unit can introduce vibration, erratic blade speed, and hydraulic pressure inconsistencies during finishing passes.
- Engine-to-Drive Safety at the Power Transfer Point — The flywheel PTO is the critical link between engine output and the trowel's hydraulic system; using the correct OEM part ensures the connection meets the load and torque ratings the machine was engineered around.
The PTO flywheel serves as the mechanical interface between the Hatz 4H50TIC diesel engine and the trowel's hydraulic or drive system, transferring rotational force from the crankshaft to downstream components. On hydrostatic ride-on trowels like the STX6H and HTX6H, this component must maintain precise balance and engagement to deliver consistent blade speed and machine control across the finishing deck. When the flywheel PTO wears, cracks, or loses its seating, operators typically experience vibration, loss of hydraulic pressure, or erratic trowel blade response — all of which compromise surface finish quality and can accelerate wear on adjacent drivetrain components.
