The Multiquip 0040004000 is a genuine OEM Spring Washer 4MM designed for the GA6HR, GA6HRS, GA6HRSNC2, GA3.6HR, GA6HEB, and GA6HB series gasoline powered generators. As a direct Multiquip OEM part, it meets the exact material and dimensional specifications required for proper fastener tension and vibration resistance in these units. Sourcing the correct spring washer ensures the integrity of bolted connections throughout the generator assembly, preventing fastener back-out during sustained operation. If you are servicing any of the listed GA-series models, part number 0040004000 is the authorized replacement.
Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's specified hardness and spring-back rating, ensuring consistent clamp load retention across the fastener joint.
- 4MM Dimensional Accuracy — Sized precisely for 4MM fastener applications, dropping into place without modification against mating hardware.
- Broad GA-Series Coverage — Compatible with GA6HR, GA6HRS, GA6HRSNC2, GA3.6HR, GA6HEB, and GA6HB gasoline powered generators.
- Vibration Resistance — Spring washers are critical in generator applications where continuous engine vibration can loosen fasteners over time; a correctly rated washer maintains clamping force through extended run cycles.
- Corrosion-Resistant Construction — Built to withstand the heat and moisture exposure typical in generator service environments, resisting surface degradation that can compromise clamping performance.
A spring washer works by using its slightly curved or split profile to maintain tension between a fastener and the surface it secures. As the nut or bolt is tightened, the washer compresses, storing mechanical energy that continuously pushes back against the fastener — preventing it from backing out due to vibration or thermal expansion cycles. In a gasoline powered generator, where the engine runs continuously and vibration is constant, even a small loss of clamping force at a critical joint can lead to loose components, misalignment, or more serious mechanical failures. Replacing a worn, flattened, or corroded spring washer with the correct OEM-spec part restores that clamping integrity and keeps fastened assemblies secure through normal service intervals.
