The Multiquip 9036 is a genuine OEM Gearbox Cover designed for HDA Series walk-behind power trowels and Whiteman ride-on power trowel models including the JWN24HTCSL, JWN24HSCSL, and HTN series. As a factory-sourced component, it delivers an exact dimensional match to the original part, ensuring correct seating and a secure enclosure for the gearbox assembly. This part is verified compatible across the HDA Series, JWN24, and HTN series trowel families, making it a straightforward service replacement for both walk-behind and ride-on configurations. Sourcing genuine OEM parts like the 9036 keeps your trowel operating to its original design standard and avoids the fitment issues that come with unverified substitutes.
Key Features
- OEM-Matched Dimensional Accuracy — Cast and finished to the same specifications as the original gearbox cover, ensuring correct mating surfaces, bolt-hole alignment, and sealing contact on every install.
- Direct Bolt-On Replacement — Mounts using the existing fastener pattern with no reworking of mounting points, keeping service time to a minimum.
- Broad Trowel Family Coverage — Confirmed fitment across HDA Series walk-behind trowels, JWN24HTCSL, JWN24HSCSL, and HTN series ride-on trowels, covering both Kohler and Honda engine configurations.
- Gearbox Protection — Maintains the sealed environment the gearbox requires to retain lubrication and exclude concrete dust and debris — common causes of premature gear and bearing wear on trowels.
- Genuine OEM Sourcing — Supplied as an authorized Multiquip OEM part through DHS Equipment, with full traceability back to the original equipment manufacturer.
The gearbox cover on a walk-behind or ride-on power trowel seals and protects the gearbox housing that transmits engine power to the trowel blade arms. It keeps gear oil contained and prevents abrasive material — particularly concrete dust and slurry — from entering the gearbox and accelerating wear on internal gears and bearings. A cracked, warped, or missing gearbox cover will lead to lubricant loss and contamination ingress, which can quickly result in gearbox failure and costly downtime on the slab.
