Multiquip 20445 Helical Service Oil 24 Oz

The Multiquip 20445 Helical Service Oil 24 Oz is a genuine OEM fluid designed for ride-on power trowel models including EHHNK5, HHN34TVD, HHNG5, HHXD5, and HHXDF4-DF5. As a factory-specified lubricant, it delivers the exact viscosity and additive profile required to protect the helical gear sets found in these machines. Sourced directly through Multiquip's OEM supply chain, 20445 ensures your trowel's gearbox receives the fluid it was engineered to run on. Confirm your model code before ordering to ensure this is the correct service fluid for your unit.

Key Features

• OEM-Specified Viscosity and Additive Package — Formulated to the exact lubrication requirements of Multiquip helical gear assemblies, not a generic gear oil substitute.
• Direct Fitment for Ride-On Power Trowel Gearboxes — Sized and specified for the helical gear systems used in EHHNK5, HHN34TVD, HHNG5, HHXD5, and HHXDF4-DF5 trowels.
• Convenient 24 Oz Service Quantity — Pre-measured volume aligned with typical gearbox service intervals, so you use the right amount without estimating.
• Protects Against Gear Wear and Heat Buildup — Proper lubrication keeps helical gears operating smoothly under the continuous load demands of concrete finishing work.
• Genuine Multiquip OEM Product — Supplied under the Multiquip part number 20445, so you can cross-reference your service manual and confirm the correct specification with confidence.

The helical gear oil in a ride-on power trowel lubricates the internal gear sets that transfer engine power to the rotating trowel blade assemblies. These gears operate under sustained mechanical load during concrete finishing passes, generating heat and surface stress that require a correctly specified lubricant to manage. Using an incorrect or degraded fluid leads to accelerated gear wear, increased operating temperatures, and ultimately gearbox failure — an expensive repair that proper fluid maintenance prevents.
