Multiquip 456437920 Pulley Washer

The Multiquip 456437920 Pulley Washer is a genuine OEM component designed for MVH-series reversible plate compactors, including the MVH304GSB, MVH408DZ, MVH408GH, MVH508DZ, and MVH508GH. Sourced directly from Multiquip, this washer is manufactured to the exact tolerances required for proper pulley seating and drive system alignment on these heavy-duty compaction machines. Confirmed fitment across the MVH304, MVH408, and MVH508 model lines means you can order with confidence and get back to work without second-guessing compatibility.

Key Features

• Genuine OEM Dimensional Accuracy — Produced to Multiquip's exact thickness and bore specifications, ensuring the pulley seats flush and maintains correct belt tension across the drive system.
• Drop-In Replacement — Matches the original mounting configuration on MVH-series compactors, fitting directly into the existing pulley stack without modification to adjacent hardware.
• Broad MVH-Series Fitment — Compatible with MVH304GSB, MVH408DZ, MVH408GH, MVH508DZ, and MVH508GH reversible plate compactors, covering both gas and diesel variants in the MVH lineup.
• Drive System Integrity — A correctly installed pulley washer maintains proper spacing and load distribution at the drive shaft, preventing uneven belt wear and preserving compaction output over extended use.
• OEM Parts Traceability — Part number 456437920 is the factory-assigned Multiquip reference, making reordering straightforward and ensuring you receive the correct component every time.

A pulley washer sits between the pulley and its mounting surface on the drive shaft, providing the precise spacing and load-bearing support needed to keep the pulley running true. On reversible plate compactors like the MVH series, the exciter drive system operates under significant rotational stress, and even minor misalignment at the pulley can accelerate belt wear or cause vibration inconsistencies that reduce compaction effectiveness. When this washer wears thin or is lost during service, replacing it with the correct OEM part restores proper pulley geometry and protects the broader drive assembly from premature wear.
