Sourced directly from Multiquip, this bearing meets the exact fit and dimensional specifications of the original part. The 35x62x14mm profile matches the OEM bearing position precisely, supporting the input pinion shaft in the pump's drive assembly. If you're servicing or rebuilding a Multiquip diaphragm pump, verifying part number 335419400 against your model ensures a correct, no-guesswork replacement.
Key Features
- Exact OEM Dimensions: — 35x62x14mm profile matches the original #6007 bearing specification for precise seating in the input pinion position.
- Genuine Multiquip Part: — Manufactured to OEM tolerances, ensuring correct load rating and rotational accuracy for the input pinion shaft.
- Direct Drive Integrity: — Supports smooth torque transfer through the input pinion assembly, keeping pump output consistent under continuous operation.
- Confirmed Fitment: — Verified for MQD2H, MQD2HA, MQD3H, and MQD3HA Multiquip diaphragm pump models.
- Rebuild-Ready Component: — A go-to replacement during pump overhauls or scheduled bearing inspections to restore drive-end performance.
The input pinion ball bearing sits at the drive end of the pump's gear assembly, supporting the pinion shaft as it transmits engine power into the diaphragm mechanism. A properly functioning bearing allows the shaft to rotate freely under load while maintaining precise shaft alignment — critical for consistent pump stroke and flow rate. When this bearing wears or fails, it can introduce shaft wobble, increase internal friction, and ultimately cause accelerated gear wear or a complete loss of pump output.
