The Multiquip 1231630000 WDF Key 5 X 16 is a genuine OEM component designed for Mayco concrete pump models C30HDNI and C30HDN. Sourced directly through Multiquip's authorized parts program, this key ensures an exact match to the original specification used on the production line. Confirmed fitment covers C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDN concrete pumps.
Key Features
- Genuine OEM Specification: — Manufactured to the exact dimensions and material grade of the original key, ensuring proper load transfer and shaft-to-hub engagement without slop or premature wear.
- Direct Drop-In Installation: — Sized at 5 x 16 to seat cleanly into the original keyway without filing or fitting adjustments.
- Broad Mayco Pump Fitment: — Compatible with C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDN Mayco concrete pump models.
- Maintains Drive Integrity: — A correctly fitted key locks the drive component firmly to the shaft, preventing rotational slippage that can cause accelerated wear to both the shaft and the mating hub.
- Verified Part Number: — Multiquip part number 1231630000 cross-references directly to this application, so you can order with confidence.
A woodruff or parallel drive key is a small but critical component that locks a rotating part — such as a pulley, sprocket, or gear — to its drive shaft, ensuring both turn as a single unit. Without a properly seated key, the mating components will slip under load, rapidly damaging the keyway and the shaft. On a concrete pump like the C30HDNI or C30HDN, where drive components operate under sustained hydraulic and mechanical loads, a worn or missing key can cause immediate loss of pump output and costly damage to surrounding drivetrain parts.
