The Multiquip 335409101 Gear Box Input Half is a genuine OEM component designed for MQD2H and MQD3H diaphragm pumps. As an authorized Multiquip replacement part, it is manufactured to the same specifications as the original, ensuring a direct, correct-fit installation in the gear box assembly. This part is verified to fit the MQD2H and MQD3H models, giving you confidence you are ordering the right component for your machine.

Key Features

  • Genuine OEM Construction — Machined to the exact tolerances of the original gear box input half, maintaining proper gear mesh and load transfer within the drive assembly.
  • Direct Drop-In Replacement — Engineered to mate with the existing gear box housing and output half on MQD2H and MQD3H diaphragm pumps without modification.
  • Confirmed Fitment — Verified compatible with Multiquip MQD2H and MQD3H diaphragm pump models.
  • Sustained Drive Performance — A correctly functioning input half delivers consistent torque from the engine to the pump mechanism; a worn or damaged half causes gear slippage, vibration, and loss of pumping output.
  • Durable Material Integrity — Produced from the same grade of material as the factory original, resisting wear and fatigue under continuous pump operation cycles.

The gear box input half is the driving side of the gear box assembly, receiving rotational power from the engine and transmitting it through the gear set to the pump's diaphragm drive mechanism. It works in close tolerance with the output half to convert engine speed into the reciprocating action that moves fluid through the pump. When the input half becomes worn, cracked, or damaged, gear engagement is compromised, leading to reduced pumping efficiency, increased noise, and potential gear box failure if left unaddressed.
