The Multiquip 45389 is a genuine OEM Hose Assembly 3/4" x 44" 12FJIC designed for LD6, LD6SL, and LD60 light-duty hydrostatic ride-on power trowels. As a direct factory replacement, this hose assembly is built to the exact length, diameter, and end-fitting specification required by the original hydraulic circuit. Sourcing a genuine OEM component means you get a part manufactured to the same tolerances as the unit that left the factory, ensuring a correct, leak-free connection. Confirm your model code against LD6, LD6SL, or LD60 before ordering to make sure 45389 is the right hose for your machine.
Key Features
- OEM-Grade Hydraulic Hose Construction — Built to withstand the pressure cycling demands of a hydrostatic trowel drive system, with hose wall integrity rated to match the original hydraulic circuit specifications.
- Exact 3/4" Bore x 44" Length with 12FJIC End Fitting — The fixed length and 12FJIC (female JIC) swaged end fitting allow direct installation into the existing hydraulic line routing without cutting, re-flaring, or adapting.
- Confirmed Fitment for LD6, LD6SL, and LD60 — Engineered specifically for Multiquip's light-duty hydrostatic ride-on trowel series; verify your model code before ordering.
- Maintains Hydraulic System Integrity — A correctly sized and rated hose keeps hydraulic pressure stable across the drive and blade-pitch circuits, preserving smooth trowel blade control and consistent machine travel.
- Hydraulic Leak Prevention — A cracked, swollen, or improperly fitted hose in this circuit can cause pressure loss, erratic blade response, or uncontrolled drive behavior; replacing with the OEM part restores safe, predictable operation.
This hose assembly carries hydraulic fluid between key components in the LD-series trowel's hydrostatic drive system. The 3/4" internal bore and 44" length are sized to maintain proper flow rate and pressure delivery across the circuit, while the 12FJIC swaged end fitting creates a metal-to-metal seal that resists loosening under vibration. When a hydraulic hose in this system deteriorates — through abrasion, heat cycling, or internal pressure fatigue — the resulting leak or pressure drop can cause sluggish or uneven blade pitch adjustment and loss of drive response. Replacing the hose with the correct OEM assembly, part number 45389, restores full hydraulic performance and keeps the trowel operating as intended.
