The Multiquip 07029-002 is a genuine OEM Split Lock Washer #8 designed for MQ Power Fuel and DEF Tank units, including the DEFTANK1, DEFTANK2, and DEFTANK302. As a factory-original component, this washer is manufactured to the same specification as the part it replaces, ensuring correct torque retention and a secure mechanical connection. If you are servicing or assembling any of these MQ Power DEF or fuel tank systems, the part is the correct OEM fastener hardware for the job.
Key Features
- Genuine OEM Hardness and Temper — Manufactured to the same material grade and spring tension spec as the original, maintaining proper clamp load under vibration and thermal cycling.
- Direct Hardware Match — #8 sizing corresponds exactly to the fastener positions on DEFTANK1, DEFTANK2, and DEFTANK302 assemblies, seating flush without shimming or modification.
- Verified Fitment — Confirmed for MQ Power Fuel and DEF Tank models DEFTANK1, DEFTANK2, and DEFTANK302.
- Vibration Resistance — The split lock profile bites into mating surfaces to resist loosening from engine vibration and equipment movement, keeping critical DEF and fuel system fasteners secure over time.
- Fuel and DEF System Safety — Loose or incorrect fastener hardware on fuel and DEF tank assemblies can result in leaks or non-compliance; using the correct OEM washer maintains a proper, sealed connection at every mounting point.
A split lock washer works by using its split, spring-tensioned profile to exert continuous pressure against the fastener and the mating surface, resisting loosening caused by vibration or repeated thermal expansion and contraction. On fuel and DEF tank assemblies like those in the DEFTANK series, this small but critical component helps maintain the integrity of every bolted connection across the tank structure and mounting hardware. When a split lock washer is worn, flattened, or missing entirely, fasteners can work loose over time, potentially compromising the security of the tank assembly and leading to leaks or structural instability.
