The Multiquip 42704 Hatz Engine ECU Mount Bracket is a genuine OEM bracket designed for HTX6H and STX6H hydrostatic ride-on power trowels and the RW1403HF roller. As a direct Multiquip OEM part, 42704 is manufactured to the exact dimensions and mounting configuration of the original component, ensuring a clean, hassle-free installation. This bracket is the correct replacement for any HTX6H, STX6H, or RW1403HF unit where the ECU mount has cracked, corroded, or been damaged in the field. Sourcing the genuine OEM part means you get the same bracket that left the factory — no guesswork on hole spacing, hardware sizing, or mounting geometry.
Key Features
- Genuine OEM Structural Integrity — Fabricated to the same material grade and dimensional spec as the original bracket, so the ECU sits securely without flex or vibration-induced stress.
- Direct Bolt-On Fitment — Mounting holes and hardware interfaces match the original Hatz engine bay layout exactly, allowing straightforward installation without reworking the mounting points.
- Confirmed Compatibility — Verified fit for HTX6H and STX6H hydrostatic ride-on power trowels and the RW1403HF roller.
- Protects Critical Engine Electronics — A properly mounted ECU bracket holds the engine control unit firmly in position, preventing connector fatigue, wiring strain, and vibration-related faults that can trigger unexpected shutdowns.
- Electrical Safety Assurance — Correct ECU mounting prevents accidental grounding, connector displacement, and wiring chafe that can cause electrical faults or engine management errors on diesel-powered equipment.
The ECU mount bracket is the structural anchor that holds the Hatz engine's electronic control unit in a fixed, vibration-resistant position within the engine bay. Without a sound bracket, the ECU is exposed to the constant vibration generated by the machine during operation, which can loosen connectors, fatigue wiring harnesses, and ultimately cause intermittent or permanent engine management faults. A damaged or missing bracket should be replaced promptly, as a dislodged ECU can result in unpredictable engine behavior or a no-start condition on the equipment.
