Key Features
- Genuine OEM Fastener Integrity — Manufactured to Multiquip's original torque-retention specification, ensuring the washer maintains clamping load under the continuous vibration experienced during pump operation.
- Direct Drop-In Replacement — Matches the original hardware profile for straightforward installation during routine service or full pump reassembly without fitment guesswork.
- Broad MQ600 Series Coverage — Confirmed fit across the MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP trash pump models.
- Vibration Resistance — Lock washers in pump assemblies resist loosening caused by engine vibration and operational loads, keeping fastened components properly secured through extended run cycles.
- Fastener System Reliability — A failed or missing lock washer can allow critical fasteners to back out, leading to misalignment, leaks, or component damage — using the correct OEM part protects the integrity of the full assembly.
A lock washer is a hardened fastener component placed beneath a nut or bolt head to prevent the fastener from loosening due to vibration, thermal cycling, or dynamic loads. In trash pump applications, where engines and impellers generate sustained vibration, lock washers play a critical role in keeping housing panels, engine mounts, and pump components properly torqued. When a lock washer becomes deformed, corroded, or is lost during service, the fastener it secures can gradually back out — potentially causing misalignment, fluid leaks, or damage to surrounding components.
