The Multiquip EM502553 Lock Washer is a genuine OEM component designed for QP3TZ and QP2TZ trash pumps and MVH408DZ and MVH308DZ heavy-duty reversible plate compactors. As a factory-sourced part, it meets the same specifications as the original hardware used in production, ensuring a consistent, reliable fit every time. If you need to confirm compatibility, reference the model codes above against your machine's serial plate before ordering.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same material hardness and dimensional tolerances as the original fastener hardware, so holding force and corrosion resistance are not compromised.
- Drop-In Installation — Matches the original thread pitch and outer diameter exactly, seating correctly against mating fastener surfaces without rework or shimming.
- Broad Multiquip Fitment — Verified for QP3TZ, QP2TZ, MVH408DZ, and MVH308DZ equipment, covering both the trash pump and heavy-duty reversible plate compactor families.
- Fastener Integrity Under Vibration — Lock washers in high-vibration applications like compactors and pumps resist bolt back-out during operation; a worn or missing washer can allow fasteners to loosen and compromise assembly integrity.
- Sourced Direct from Multiquip — Supplied as a genuine OEM replacement, meaning part number EM502553 is traceable to Multiquip's own parts program for accurate order verification.
A lock washer is a small but critical piece of hardware placed beneath a nut or bolt head to resist loosening caused by vibration, torque, and thermal cycling. In equipment like plate compactors and trash pumps — which generate continuous vibration during operation — fasteners without proper locking hardware can back out over time, leading to component misalignment, fluid leaks, or mechanical failure. Replacing a worn, deformed, or missing lock washer with the correct OEM part restores the clamping integrity of the fastened joint and helps keep the surrounding assembly secure through normal working loads.
