Multiquip JDT111383 Fuel Filter STH-55JD-TC

The Multiquip JDT111383 Fuel Filter STH-55JD-TC is a genuine OEM fuel filter designed for the STX55J6 and STX55Y6 super-sized hydrostatic ride-on power trowels. As a direct OEM replacement, JDT111383 is sourced and verified to meet Multiquip's original build specifications, so you get a part that installs exactly as the original did with no guesswork. DHS Equipment stocks this part as an authorized Multiquip OEM component, giving you confidence that you're ordering the correct filter for your machine.

Key Features

• OEM Filtration Integrity — Engineered to the same filtration rating and element media as the original, ensuring consistent fuel cleanliness entering the engine's fuel system.
• Direct-Connect Replacement — Matches the original inlet/outlet fittings and mounting orientation on STX55J6 and STX55Y6 trowels for a straightforward swap during scheduled service.
• Confirmed STX55 Series Fitment — Verified for the STX55J6 (John Deere diesel) and STX55Y6 (Yanmar diesel) super-sized hydrostatic ride-on trowel models.
• Protects Engine Fuel Delivery — A clean, functioning fuel filter prevents particulates from reaching injectors and fuel system components, maintaining steady power output and smooth trowel operation.
• Fuel System Safety Compliance — Using the correct OEM-specified filter helps ensure the fuel system operates within the pressure and flow parameters the engine was designed for, reducing the risk of fuel delivery faults on the jobsite.

The fuel filter's role is to remove dirt, debris, and water contamination from the fuel supply before it reaches the engine's injection or carburetion system. On hydrostatic ride-on trowels like the STX55 series, consistent and clean fuel delivery is critical to maintaining steady hydraulic power for both blade pitch control and machine drive. A clogged or degraded fuel filter restricts fuel flow, which can cause rough running, loss of power, hard starting, or stalling mid-operation — interruptions that affect both productivity and surface finish quality.
