FLEXILOCK hydraulic pump drive kit showing driveplate with polymer element and CLAMPLOCK hub

Flexilock Hydraulic Pump Drive kits for Diesel Engines

FLEXILOCK hydraulic pump drive kits are precision engineered single pump drive systems designed to interface SAE diesel engines with hydraulic pumps. Available in four power sizes and offering more than 300 standard configurations, FLEXILOCK provides one of the most comprehensive ranges of direct hydraulic pump drive kits in Australia.

Each FLEXILOCK hydraulic pump drive kit includes a steel flywheel driveplate with integrated polymer drive element, a precision-machined drive hub and an engine housing adaptor. For splined pump applications, kits utilise the CLAMPLOCK spline locking mechanism to secure the hub to the pump shaft and maintain correct engagement under load.

The specially formulated polymer element is designed to operate at engine temperatures while absorbing torsional vibrations, helping improve durability and long service life in demanding industrial and mobile applications.

To explore the full FLEXILOCK hydraulic pump drive kit range, installation resources and compatibility guides, visit the dedicated FLEXILOCK product page.

FLEXILOCK kits are supported by detailed installation instructions, SAE dimension guides and a Drive Kit Selection App to assist with correct engine and pump identification. 

CLAMPLOCK companion flange and yoke for driveline spline connection in industrial machinery

Driveline Innovation – CLAMPLOCK Technology 

CLAMPLOCK is an Australian engineered spline locking technology designed to improve the performance and reliability of heavy-duty driveline and drivetrain systems. By eliminating spline backlash and preventing fretting wear, CLAMPLOCK enhances torque transmission across critical driveline components.

Integrated across Dynagear driveline products including companion flanges, couplings, drive kits and yokes, CLAMPLOCK delivers a robust solution for mining, transport and industrial applications where reliability is essential.
