The Multiquip CD290033 Fourth Gear is a genuine OEM component designed for DM15A9C and CDM2CSA series core drill equipment. Sourced directly from Multiquip, this gear meets the original design specifications for exact fitment within the drivetrain. It is a direct replacement for the original part, ensuring proper engagement and operation within the gearbox assembly. Verify your model code against DM15A9C or CDM2CSA before ordering to confirm compatibility.
Key Features
- Genuine OEM Gear Integrity — Manufactured to the original tooth profile and hardness specs, maintaining proper mesh and load transfer within the transmission.
- Direct Drivetrain Fitment — Engineered to drop into the existing gearbox position on DM15A9C and CDM2CSA models without modification to surrounding components.
- Compatible with DM15A9C and CDM2CSA — Confirmed fitment across Multiquip drill rig stand and core drill configurations in this equipment family.
- Sustained High-Range Performance — Fourth gear governs the top-speed drilling range; a worn or damaged gear causes slippage, noise, and loss of drilling speed control.
- OEM Part Number Assurance — Part number this part is the Multiquip catalog reference, eliminating guesswork when cross-referencing your service manual or parts breakdown.
The fourth gear is a critical component within the core drill's multi-speed gearbox, responsible for transmitting engine power to the drill spindle at the highest speed ratio. It works in constant engagement or selective mesh with mating gears to deliver the correct rotational speed for high-range coring operations. When this gear wears or chips, operators will notice difficulty shifting into top range, unusual grinding noise, or a complete loss of drive at that speed setting — all of which halt productive drilling until the gear is replaced.
