The Multiquip 05054700 is a genuine OEM Nut for Rocker Arm designed for QP3TZ, QP2TZ, MVH408DZ, and MVH308DZ equipment. As a factory-sourced component, it meets the exact specifications required to maintain proper valve train geometry and rocker arm function on Hatz diesel-powered trash pumps and heavy-duty reversible plate compactors. This part is a direct OEM replacement, ensuring correct thread pitch, torque retention, and dimensional accuracy for a proper fit on compatible engines. Verify your model and engine configuration against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Thread Specification — Sourced directly from Multiquip, this nut meets the exact thread pitch and hardness grade required for secure rocker arm retention on Hatz diesel engines.
- Drop-In Engine Replacement — Engineered to the same dimensional tolerances as the original hardware, allowing it to seat correctly on the rocker arm stud without reworking or adapting surrounding components.
- Broad Fitment Across Two Equipment Families — Compatible with QP3TZ and QP2TZ trash pumps as well as MVH408DZ and MVH308DZ heavy-duty reversible plate compactors sharing the same Hatz diesel engine platform.
- Valve Train Stability — A properly torqued rocker arm nut locks valve clearance settings in place, ensuring consistent engine breathing, smooth power delivery, and protection against valve train wear.
- Critical Fastener Integrity — A loose or damaged rocker arm nut can cause valve clearance drift, leading to rough running, power loss, or potential engine damage — making timely replacement with the correct OEM part essential.
The rocker arm nut is a critical fastener in the engine's valve train assembly. It secures the rocker arm to its stud and locks in the valve clearance adjustment, which controls how precisely the intake and exhaust valves open and close during each engine cycle. When this nut loosens or fails, valve clearance shifts out of specification, causing misfires, increased wear on valve components, and a noticeable drop in engine performance — problems that compound quickly under the sustained load conditions typical of compaction and pumping applications.
