The Multiquip 20985 Housing Complete, Drive Motor Right Hand is a genuine OEM component designed for STX55J6 and STX55Y6 hydrostatic ride-on power trowels. This part is sourced directly through Multiquip's authorized parts program, ensuring it meets the exact design specifications of the original component. Compatible fitment is confirmed for the STX55J6 and STX55Y6 series, making it a direct replacement for the factory right-hand drive motor housing assembly.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material specifications of the STX55 hydrostatic drive system, ensuring correct tolerancing and housing integrity at the motor interface.
- Direct-Mount Replacement — Engineered to bolt into the existing right-hand drive motor position without modification to surrounding hydraulic or structural components.
- Confirmed STX55 Series Fitment — Verified compatible with the STX55J6 and STX55Y6 hydrostatic ride-on trowel models.
- Protects Drive Motor Alignment — A properly seated housing maintains precise drive motor positioning, which is critical to consistent blade speed and smooth machine tracking on the slab.
- Hydraulic System Integrity — The housing assembly forms a sealed interface within the hydrostatic drive circuit; a cracked or damaged housing can result in hydraulic fluid loss and loss of drive function on one side of the machine.
The drive motor housing on a hydrostatic ride-on trowel serves as the structural and sealed enclosure for the hydraulic drive motor on the right-hand side of the machine. It maintains correct motor positioning, supports the hydraulic connections that deliver fluid pressure to drive the trowel across the slab, and protects the internal motor components from contamination. When the housing is cracked, warped, or worn at the sealing surfaces, the machine can lose hydraulic pressure to the right-hand drive circuit, causing uneven tracking, loss of forward motion, or a complete drive failure on that side.
