The Komatsu PC200 excavator is widely used in construction, earthmoving, quarrying, and general excavation applications. Its boom, arm, and bucket linkage components operate under repeated loads and movement. High-quality bushings are important for maintaining proper clearance, reducing friction, and protecting the surrounding linkage components.

Xiamen Doozer supplies durable aftermarket bushings for Komatsu PC200 excavators. Our bushings are designed for key pivot and linkage applications, including bucket, arm, and related hydraulic cylinder assemblies, depending on the machine configuration.

Komatsu PC200 models can use different bushing part numbers depending on the excavator generation, serial number, arm configuration, and installation position. Public parts references include 205-70-67150, 205-70-72180, 205-70-73180, 20Y-70-32410, and 20Y-70-32420 for different PC200 applications. In particular, 20Y-70-32420 is listed as a bucket bushing for PC200 and related Komatsu excavators.

Our replacement bushings are manufactured with controlled dimensions and precision machining to provide a consistent fit between pins and bores. Wear-resistant material and suitable surface treatment help reduce friction and slow down clearance growth during repeated operation.

A worn bushing can cause excessive movement, abnormal noise, uneven pin wear, and increased clearance in the linkage system. Replacing the bushing together with an inspected or renewed pin can help restore proper operating clearance and improve the service life of the linkage assembly.

Xiamen Doozer provides factory-direct aftermarket excavator bushings with different sizes and configurations available according to customer requirements. We can also supply matching excavator pins, seals, bucket linkage components, and other replacement parts.

Before ordering, customers should confirm the exact PC200 model, serial number, installation position, existing part number, and dimensions. This is particularly important because PC200-5, PC200-6, PC200-7, PC200-8, and other variants can use different bushing configurations.
