As a direct OEM replacement, this lock washer meets the original engineering specifications Multiquip built these machines around, ensuring a secure, rattle-resistant connection in demanding compaction and pumping applications. Sourced directly through authorized Multiquip supply channels, part number 50255 is the correct service replacement for these models. Keep one on hand for scheduled maintenance or field repairs to restore fastener integrity quickly.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact material hardness and bite geometry specified for Multiquip equipment, delivering the clamping retention a lock washer must provide under vibration-heavy operation.
- Drop-In Service Replacement — Matches the original dimensions and thread engagement profile, so it installs directly without sizing adjustments on covered models.
- Broad Multiquip Fitment — Compatible with MVH308DZ, MVH408DZ, and MVH508DZ reversible plate compactors and QP2TZ and QP3TZ trash pumps, covering a wide range of common Multiquip service needs with a single part number.
- Vibration Resistance Where It Counts — Plate compactors and trash pumps generate sustained mechanical vibration that causes standard fasteners to back off over time; a properly functioning lock washer maintains clamping load and prevents loosening.
- Correct Part for the Application — Using part number 50255 ensures the washer spec matches the fastener assembly as engineered — critical in high-cycle equipment where an undersized or wrong-profile washer can lead to fastener failure.
A lock washer is a hardened fastening component placed beneath a bolt or nut to resist rotational loosening caused by vibration and dynamic loads. In equipment like reversible plate compactors and trash pumps — both of which operate under continuous vibration — lock washers play a quiet but essential role in keeping critical assemblies secure. When a lock washer is worn flat, missing, or substituted with an incorrect size, fasteners can gradually back out, leading to component misalignment, accelerated wear, or unexpected mechanical failure during operation.
