Hamm Drive Disc - OEM Number: 78240210

The Hamm Drive Disc (OEM 78240210) is a genuine replacement drivetrain component designed for use on selected Hamm compaction equipment. The drive disc forms part of the machine's drive assembly, transmitting rotational force between connected components to ensure smooth, efficient, and reliable power transfer during operation.

Manufactured to OEM specifications from high-strength steel, the drive disc is engineered to withstand continuous torque, vibration, and the demanding conditions encountered on construction and civil engineering sites. Precision-machined for an accurate fit, it is designed as a direct replacement component to restore the performance and reliability of the drive system.

• Transmits drive between connected drivetrain components
• Ensures smooth and efficient power transfer
• Maintains correct alignment within the drive assembly
• Withstands high torque and operational loads
• Resists vibration and harsh working conditions
• Designed for heavy-duty compaction applications

Always verify compatibility using the machine model, serial number, and OEM part number before ordering, as drive discs can vary in diameter, thickness, mounting arrangement, and application between machine models and production revisions.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, serial number, and drive system specification before ordering, as drive discs are manufactured to precise dimensions and tolerances. Installing the correct component is essential to maintain reliable power transmission, minimise wear, and ensure safe machine operation.

Common signs that a drive disc requires replacement include excessive wear, cracking, distortion, scoring, corrosion, or vibration during operation. When replacing the drive disc, it is recommended to inspect the associated shafts, bearings, couplings, mounting hardware, and surrounding drivetrain components for signs of wear or damage. Replacing any worn associated components at the same time will help maximise the reliability and service life of the complete drive assembly.
