E345GC Excavator Swing Drive Gearbox 536-7294 584-2681 5367294 5842681

The CAT345GC swing reduction gear (swing drive unit) is a core component of the CAT345GC excavator's swing system. Featuring a two-stage planetary gear reduction design, it delivers ample rated swing torque and a swing speed of 8.27 rpm, striking an optimal balance between swing power and operational smoothness.

The gears are precision-machined from high-strength alloy steel and heat-treated to ensure exceptional impact resistance; this enables them to withstand demanding construction site conditions while minimizing issues such as gear breakage, wear, and abnormal noise. A built-in swing cushion valve absorbs shock loads during startup and shutdown, thereby reducing machine vibration and protecting the swing bearing, large ring gear, and chassis structure, which ultimately lowers maintenance costs.

Optimized sealing and lubrication designs ensure long-lasting lubrication, extend maintenance intervals, and minimize the risk of oil leakage. Each unit undergoes rigorous factory testing; mounting flanges, oil ports, and mounting holes strictly adhere to OEM specifications, allowing for direct replacement without structural or piping modifications, ensuring easy installation.

Designed specifically for the CAT345GC large excavator, this product is available as a complete swing reduction gear assembly or as individual repair components (including planetary gears, sun gears, internal ring gears, bearings, oil seals, and gaskets).

All products are inspected prior to shipment and securely packed in reinforced wooden crates. We offer nationwide shipping; for export orders, we provide fumigated wooden packaging that meets quarantine requirements.

The swing part of excavator is one of the important components, and it needs regular maintenance to ensure its normal operation and extend its service life. Here are some common steps for maintaining the swing of excavator:

• Cleaning the swing part: Use a high-pressure water gun or detergent to clean the swing part to remove accumulated dirt, dust and other debris. Make sure it is cleaned thoroughly and be careful not to spray water directly into the electrical and hydraulic components.
• Lubricate the swing part: Check and lubricate the lubrication points of the swing part, including the swing bearing, gears and connecting parts. Use appropriate lubricants and lubricate according to the manufacturer's recommendations.
• Inspect the swing bearing: Check the wear and looseness of the swing bearing. Make sure there is no abnormal noise or excessive looseness of the swing bearing. If any abnormality is found, it should be repaired or replaced in time.
• Inspect the gears and transmission parts: Check the wear of the gears, chains and transmission parts of the swing part. Clean, lubricate or replace if necessary.
• Inspect the electrical system: Check the electrical system of the swing part, including the connecting lines, switches and sensors. Make sure the electrical system is working properly and there are no damaged or loose parts.
• Check the hydraulic system: Check the hydraulic system of the swing part, including the quality and level of the hydraulic oil. If necessary, replace the hydraulic oil and clean the hydraulic filter.
• Check the safety devices: Make sure that the safety devices of the swing part, such as warning lights, sound alarms and limiters, are working properly.

Please note that the above steps are only general guidelines, and the specific maintenance procedures and requirements may vary depending on the model, year and manufacturer. Therefore, it is recommended to refer to the user manual of the excavator or consult a professional technician to ensure the correct swing maintenance procedures. In addition, regular maintenance and inspections are essential to keep the excavator in good condition and safe operation.
