Multiquip 4684 Pulley Washer

The Multiquip 4684 Pulley Washer is a genuine OEM component designed for MVH series reversible plate compactors and select HTN and HHN series ride-on power trowels. Sourced directly from Multiquip, this washer matches the exact material and dimensional specifications of the original part installed at the factory. Compatible models include MVH508DE, MVH508GV, MVH508GH, MVH508DZ, MVH408DE, MVH408GV, MVH408GH, MVH408DZ, MVH208GH, MVH158GH, MVH128GH, HTN28K, HTN27K, HHN34TVD, HHN31V, and additional HTN and JWN series machines. Ordering by part number 4684 ensures you receive the correct washer for your specific machine configuration.

Key Features

• Genuine OEM Material Integrity — Manufactured to Multiquip's original hardness and thickness tolerances, ensuring the washer seats and clamps correctly against the pulley without deforming under belt tension loads.
• Drop-In Installation — Matches the original bore diameter and outer profile exactly, slipping into place on the pulley shaft without any modification to the surrounding hardware.
• Broad MVH Series Coverage — Confirmed fit across MVH128GH, MVH158GH, MVH208GH, MVH408 and MVH508 variants, spanning both Honda and diesel-powered reversible plate compactor configurations.
• Maintains Drive System Alignment — A correctly seated pulley washer keeps the belt or drive element properly positioned on the shaft; a worn or missing washer allows lateral movement that accelerates belt wear and causes slippage.
• Part Number 4684 — Verified OEM Reference — Cross-reference this number against your machine's parts manual to confirm fitment before ordering, eliminating guesswork on multi-model platforms.

A pulley washer is a precision spacer and clamping element that sits between the pulley hub and an adjoining shaft component, maintaining correct axial positioning of the pulley on the drive shaft. It distributes clamping load evenly so the pulley is held firmly without concentrating stress on the shaft threads or hub face. When this washer is missing, undersized, or deformed, the pulley can shift laterally under load, leading to misaligned belt tracking, accelerated belt and pulley wear, and in more severe cases, unexpected drive slippage that reduces compaction force or disrupts blade speed on trowel applications.
