The Multiquip 20630 is a genuine OEM Left-Hand Drive Motor Housing Complete designed for HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 hydrostatic ride-on power trowels. As a direct Multiquip OEM part, 20630 is manufactured to the exact specifications of the original component, ensuring correct fitment and full hydraulic drive function on HTX44 series machines. This housing assembly is a critical structural and functional component of the drive motor circuit, and sourcing a genuine replacement protects the integrity of your trowel's hydraulic drive system. DHS Equipment stocks this part to keep your HTX44 trowel turning blades and moving across the slab without compromise.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Multiquip's original specifications, ensuring correct port alignment, thread engagement, and internal tolerancing for the HTX44 drive motor circuit.
- Left-Hand Side Specific — Designed exclusively for the left-hand drive motor position; correct side-specific fitment eliminates installation guesswork and ensures proper hydraulic circuit routing.
- HTX44 Series Compatibility — Verified fit for HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 hydrostatic ride-on trowels — covering both Kubota and Yanmar engine configurations in this series.
- Drive System Performance — A sound housing assembly maintains proper hydraulic pressure containment at the drive motor; a cracked or worn housing causes fluid loss, loss of traction control, and uneven blade rotation across the deck.
- Complete Assembly — Supplied as a housing with assembly (W/A), reducing the number of individual components needed to complete a drive motor repair on the left-hand side.
The drive motor housing on a hydrostatic ride-on trowel serves as the structural enclosure for the hydraulic drive motor on one side of the machine, channeling pressurized hydraulic fluid to generate the rotational force that propels the trowel across the concrete surface. On HTX44 series machines, the left-hand and right-hand drive motors work in coordination to provide steering and forward motion, so a compromised housing on either side directly affects maneuverability and finish quality. When this housing cracks, leaks, or becomes damaged, hydraulic fluid loss leads to reduced drive force, inconsistent travel speed, and potential damage to the motor itself — making prompt replacement with a correct OEM part essential to keeping the machine productive.
