The Multiquip 45437-SK LH Steering Valve with Switch Assembly is a genuine OEM component designed for the MD80, MD105, and LD60 hydraulic ride-on power trowels. As a direct factory replacement, this assembly ensures the left-hand steering circuit operates exactly as engineered, with the integrated switch delivering the correct signal response to the machine's hydraulic control system. Sourced directly through Multiquip's authorized parts network, the 45437-SK is built to the same specification as the original unit installed at the factory. If you're tracing a steering response issue or completing a full hydraulic steering rebuild on your MD or LD series trowel, this is the correct OEM part for the job.
Key Features
- Genuine OEM Hydraulic Valve: — Manufactured to Multiquip's exact pressure and flow specifications for the LH steering circuit — not a generic valve adapted to fit.
- Integrated Switch Assembly: — The valve and switch ship as a complete, pre-assembled unit, allowing straightforward installation into the existing hydraulic and electrical connections without sourcing components separately.
- Confirmed Fitment for MD and LD Series Trowels: — Directly fits MD80, MD105, and LD60 ride-on power trowels, covering both mid-sized and light-duty hydrostatic trowel platforms.
- Restores Full Steering Authority: — A failed or leaking LH steering valve causes sluggish, uneven, or non-responsive left-hand steering control; replacing it with 45437-SK brings the machine back to full hydraulic steering performance.
- Hydraulic System Safety: — Steering valve integrity is critical to operator control on a ride-on trowel; using the correct OEM-spec valve maintains the hydraulic pressure balance required for safe, predictable machine handling.
The LH steering valve with switch assembly controls the flow of hydraulic fluid to the left-hand drive circuit on hydrostatic ride-on trowels, translating operator input into directional machine movement. The integrated switch signals the control system to engage or modulate the left-side drive, allowing smooth, coordinated steering across the work surface. When the valve leaks, sticks, or the switch fails, operators experience unresponsive or erratic left-side steering — making this assembly one of the first components to inspect when handling performance declines on MD or LD series machines.
