Multiquip 544006 Drive Shaft Splined H-13 - OEM Replacement Part

This splined drive shaft transfers rotational power from the engine to the blade assembly in Multiquip concrete saws, providing the precise torque transmission needed for demanding cutting applications. Manufactured from heat-treated H-13 tool steel, this shaft is engineered to withstand the extreme stress and heat generated during heavy-duty concrete cutting operations.

The splined design ensures positive engagement and power transfer while allowing for thermal expansion during extended use. H-13 steel is specifically chosen for its superior hot hardness, wear resistance, and toughness—critical properties for components subjected to high rotational speeds and shock loads. When drive shafts fail, operators typically notice excessive vibration, unusual noise during operation, or difficulty maintaining consistent blade speed under load.

This drive shaft is compatible with the following Multiquip saw models:

• SP605716
• SP6457

Regular inspection of the drive shaft for wear, spline damage, or heat discoloration can prevent unexpected downtime and costly secondary damage to transmission components. Genuine Multiquip OEM part, sold by an authorized dealer.
