The Multiquip 01345400 Cooling Air Duct Assembly is a genuine OEM component designed for MVH406, MVH-406DSZ, and QP4TZ series equipment. As a direct OEM replacement, this assembly is built to the same specifications as the original, ensuring proper airflow routing and thermal management across compatible machines. Sourced directly through authorized channels, the part is the correct replacement when the original duct shows cracking, heat damage, or airflow restriction. Verify your model code against the fitment list to confirm compatibility before ordering.
Key Features
- OEM Airflow Geometry — Engineered to the original duct profile, maintaining the correct air channel dimensions that the engine cooling system depends on for consistent thermal performance.
- Direct-Fit Replacement — Designed to mount in the same position and orientation as the original assembly, with matching attachment points for a clean, straightforward installation.
- Broad Fitment Coverage — Compatible with MVH406 and MVH-406DSZ reversible plate compactors, as well as the QP4TZ trash pump, covering multiple Multiquip equipment families with a single part number.
- Protects Engine Operating Temperature — A properly functioning cooling air duct directs airflow precisely where the engine needs it; a cracked or displaced duct allows heat to build unchecked, accelerating wear on engine internals.
- Genuine OEM Quality — Manufactured to Multiquip OEM standards, ensuring the material grade and structural integrity match what was originally installed on the machine.
The cooling air duct assembly channels air from the engine's recoil or intake side directly over the cylinder fins and other heat-generating components, maintaining safe operating temperatures during sustained use. Without a properly sealed and correctly routed duct, airflow is lost to the surrounding environment rather than directed to where it is needed, causing the engine to run hotter than designed. Over time, an degraded or missing duct leads to overheating, reduced power output, and accelerated engine wear — making timely replacement essential to keeping the machine running at full capacity.
