Complete Gearbox

When an excavator travel or slewing gearbox breaks down on site, the whole job quickly slows to a halt. Taking apart heavy undercarriage parts, cleaning up leaked oil, and struggling with ill-fitting replacement units are common headaches for every maintenance team. Many aftermarket gearboxes fail early simply because they are not built to match original specs, leading to weak power, unstable movement and extra repair costs down the line.

We supply genuine replacement complete gearbox for heavy excavators, covering travel drive gearbox and slewing reduction gearbox for mainstream machine models. Every unit is manufactured to match original installation dimensions and working parameters, so it can be mounted directly without extra cutting, drilling or on-site modification. Matched gear ratio and torque output ensure steady performance under heavy load and rough working conditions.

Before shipment, every complete gearbox goes through manual inspection. Our workers run gear rotation checks, measure backlash, confirm seal installation and inspect housing integrity. We strictly screen out defective units to prevent internal wear or hidden faults from reaching customers. Considering the harsh conditions of international logistics, all gearboxes are packed with reinforced export packaging, reducing collision and damage risks during long-distance shipping.

Most regular models are kept in stock to meet urgent replacement needs. In-stock orders can be arranged for shipment within one working day, and bulk orders will be finished and dispatched within two weeks. All our excavator gearbox parts come with a 6-month warranty period. If any quality problem occurs during use, we will provide practical after-sales solutions in a timely manner.

Instead of choosing universal adaptive parts with unstable quality, selecting model-specific complete gearbox can better adapt to your machine's original working performance. If you cannot confirm compatibility, send us your equipment model and the part number of your old gearbox. We will check the cross reference and help you find a suitable replacement to get your excavator back into normal operation quickly.
