The Multiquip 45326 Hydraulic ELD 1.5H Heat Exchanger is a genuine OEM component designed for LD6, LD6SL, and LD60 series hydrostatic ride-on power trowels. As a direct factory replacement, part 45326 maintains the hydraulic system's thermal management performance to the same specification as the original unit. This part is sourced from Multiquip and is verified for compatibility with the LD-series light-duty hydrostatic trowel lineup. Keeping the hydraulic system within its correct operating temperature range is critical to consistent blade control and drive response on these machines.
Key Features
- Genuine OEM Thermal Specification — matched to the exact cooling capacity required by the LD-series hydrostatic system, ensuring the hydraulic fluid stays within its designed operating temperature range.
- Direct-Fit Replacement — engineered to mount in the same position and connect to the same hydraulic and airflow pathways as the original 45326 unit, simplifying installation.
- Confirmed LD-Series Compatibility — verified for use on LD6, LD6SL, and LD60 hydrostatic ride-on power trowels.
- Protects Hydraulic Components Downstream — a properly functioning heat exchanger prevents fluid breakdown and protects pumps, motors, and control valves from heat-related wear.
- Fuel System Safety Relevance — overheated hydraulic fluid in a ride-on trowel can cause erratic blade pitch response and loss of drive control; this OEM exchanger restores safe, predictable machine behavior.
A hydraulic heat exchanger removes excess thermal energy from the hydraulic fluid as it circulates through the system. In a hydrostatic ride-on trowel like the LD6 or LD60, the hydraulic circuit controls both blade pitch adjustment and machine drive, so fluid temperature directly affects how precisely and consistently the operator can control the machine. When the heat exchanger becomes blocked, leaks, or fails, fluid temperatures rise beyond safe limits, leading to fluid degradation, seal failure, sluggish or unpredictable blade response, and potential damage to pumps and motors throughout the hydraulic circuit.
