The Multiquip 42728 Module Left Hydraulic Cooler is a genuine OEM component designed for the HTX6H heavy-duty hydrostatic ride-on power trowel. As a direct OEM replacement, part 42728 is manufactured to the exact specifications of the original unit, ensuring a proper fit within the HTX6H hydraulic cooling system. If your machine is running hot or showing signs of hydraulic overheating, replacing a worn or failed cooler module with the correct OEM part is the surest path back to full operation. DHS Equipment stocks genuine Multiquip parts so you can get your HTX6H back on the slab without delay.
Key Features
- Genuine OEM Construction — Manufactured by Multiquip to the exact material and dimensional specifications of the original cooler module, ensuring consistent thermal performance in the HTX6H hydraulic circuit.
- Direct Drop-In Replacement — Engineered as the left-side cooler module for the HTX6H, this part installs in the same position and connects to the same hydraulic lines as the original, with no improvised fitment.
- Confirmed HTX6H Fitment — Verified for the Multiquip HTX6H heavy-duty hydrostatic ride-on power trowel; always cross-reference part number 42728 before ordering.
- Protects Hydraulic System Integrity — A functioning cooler module keeps hydraulic fluid temperatures within safe operating range, preventing viscosity breakdown, seal damage, and pump wear that can result from sustained overheating.
- Critical for Continuous-Duty Troweling — Ride-on trowels operate under sustained hydraulic load; a compromised cooling module can cause progressive system degradation, making timely replacement essential for full-shift productivity.
The hydraulic cooler module is responsible for dissipating heat generated by the HTX6H's hydrostatic drive system during operation. As the machine's hydraulic fluid circulates under pressure to control blade pitch and drive movement, it accumulates heat that must be managed to keep viscosity and system pressure within specification. When the cooler module fails or becomes restricted, fluid temperatures rise, accelerating wear on pumps, motors, and seals throughout the hydraulic circuit and potentially causing the machine to lose drive or blade-pitch control mid-pour.
