The Multiquip 335409001 Gear Box Output Half is a genuine OEM component designed for MQD2H and MQD3H diaphragm pumps. This is a direct OEM replacement sourced from Multiquip, ensuring it meets the original design tolerances and dimensional specs required for correct operation within the gear box assembly. Verify your model code against the fitment data — this part is confirmed for MQD2H and MQD3H series diaphragm pumps. Keeping the gear box assembly intact with the correct OEM half is critical to maintaining proper power transmission to the pump's diaphragm mechanism.
Key Features
- Genuine OEM Gear Mesh Integrity — Manufactured to original gear geometry specifications, ensuring the output half meshes correctly with mating gear box components without play or misalignment.
- Direct Drop-In Fit — Engineered to the same dimensions as the original, allowing straightforward installation into the existing gear box housing with no rework to mounting points or shaft interfaces.
- Confirmed Fitment for MQD2H and MQD3H — Verified compatibility with Multiquip MQD2H and MQD3H diaphragm pump models; always confirm your unit's model code before ordering.
- Sustained Power Transfer — A correctly fitted output half maintains consistent torque delivery from the drive shaft to the diaphragm mechanism, keeping pump output steady and preventing erratic or diminished flow.
- Reduced Wear on Adjacent Components — An OEM-spec output half preserves correct gear contact patterns, protecting bearings, seals, and the mating input components from accelerated wear caused by an ill-fitting replacement.
The gear box output half is one of two primary structural and mechanical halves of the diaphragm pump's gear box assembly. It transmits rotational power from the drive source through the gear train, converting it into the reciprocating motion that drives the pump diaphragm. When this component is worn, cracked, or dimensionally out of spec, the gear mesh breaks down — leading to vibration, power loss, accelerated internal wear, and ultimately pump failure. Replacing it with the correct OEM part restores the precise gear engagement the assembly was designed around.
