The Multiquip 337009101 Gear Box Input Half is a genuine OEM component designed for MQD2HA and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. It is confirmed compatible with the MQD2HA and MQD3HA pump models, making it a straightforward direct replacement for worn or damaged input halves. Keeping this component in proper working condition is critical to maintaining consistent pump output and drivetrain integrity.
Key Features
- Genuine OEM Construction — Machined to the exact tolerances of the original gear box input half, ensuring proper gear engagement and load transfer within the drivetrain.
- Direct Drop-In Replacement — Engineered to mate with the existing gear box housing and output half on MQD2HA and MQD3HA pumps, requiring no modification to the pump assembly.
- Confirmed Fitment — Verified for use on MQD2HA and MQD3HA Multiquip diaphragm pumps.
- Sustained Pump Drive Performance — A correctly functioning gear box input half delivers smooth, consistent power transfer to the pump mechanism; a worn or cracked half causes gear slip, vibration, and loss of pumping capacity.
- Genuine Multiquip Part Number — Part number 337009101 is the correct OEM reference for this component, eliminating guesswork when ordering a replacement.
The gear box input half is one of two mating halves that together form the gear box housing on a diaphragm pump. It transmits rotational power from the engine-driven input shaft into the gear set, which in turn drives the diaphragm back and forth to move fluid through the pump. When this component cracks, wears at the mating surface, or develops play, it disrupts the alignment of the gear set and can lead to accelerated wear on surrounding components or a complete loss of pump function. Replacing it promptly with a genuine OEM part restores the drivetrain to its original operating condition.
