Reliable CAT Swing Drives (Without Motor) for Excavators – OEM & Aftermarket Solutions

TOSOG supplies high-quality CAT Swing Drives without motors that are precision-engineered to deliver exceptional durability, smooth and controlled rotation, and extended service life in some of the most demanding operating conditions. Our swing drive gearboxes are designed to perform reliably in heavy earthmoving, mining, quarrying, civil construction, and plant hire applications throughout South Africa, where equipment is subjected to high loads, constant rotation cycles, abrasive environments, and extreme operating hours.

Each CAT swing drive supplied by TOSOG is manufactured or sourced to meet OEM-equivalent performance standards, ensuring optimal torque transfer, minimal backlash, and consistent swing motion. By supplying the swing drive without the hydraulic motor, we provide a cost-effective repair and replacement solution that allows customers to reuse an existing, serviceable CAT swing motor. This approach significantly reduces capital expenditure while restoring full swing functionality and operational efficiency to the excavator.

Our swing drives are ideally suited for repairs, retrofits, component overhauls, and fleet maintenance programmes, particularly where the swing motor remains in good condition but the gearbox has suffered wear, noise, oil contamination, or internal gear failure. Replacing only the swing drive gearbox shortens repair turnaround times, minimizes machine downtime, and avoids the unnecessary expense of replacing an entire swing motor assembly.

Whether you operate a large Caterpillar excavator fleet in mining or construction, manage plant hire equipment, or maintain machines within a heavy-equipment workshop or rebuild facility, TOSOG delivers dependable, application-specific swing drive solutions backed by technical support and part-matching expertise. Our focus on quality, compatibility, and availability enables customers to maximize machine uptime, extend component life, and reduce overall operating and maintenance costs without compromising performance or reliability.

What Is a CAT Swing Drive (Without Motor)?

A CAT Swing Drive (without motor) is the gearbox assembly responsible for rotating the excavator upper structure (house) relative to the undercarriage. Supplied without the hydraulic motor, this unit is designed to interface directly with your existing swing motor—making it a cost-efficient option when the motor is still serviceable.
