Multiquip 335412000 Gear Output - OEM Replacement Part

The output gear is a critical transmission component in diaphragm water pumps, responsible for transferring power from the engine crankshaft to the pump's reciprocating mechanism. This precision-machined gear ensures proper pump operation by maintaining the correct speed reduction ratio and timing for the diaphragm assembly, directly affecting flow rate, pressure output, and overall pump performance.

When an output gear fails or wears beyond tolerance, symptoms include unusual grinding or rattling noises during operation, inconsistent water flow, reduced pumping capacity, or complete pump failure. Regular inspection of the gear teeth for wear, pitting, or damage is essential during routine maintenance to prevent unexpected downtime on job sites.

This output gear is specifically engineered for Multiquip D2H and D3H series diaphragm pumps, manufactured to exact OEM specifications for proper fitment and durability. Using genuine Multiquip components ensures compatibility with existing transmission assemblies and maintains warranty coverage.

Compatible with the following Multiquip models:
