208-70-13141 Bushing for Komatsu PC400 & more

The 208‑70‑13141 bushing (also listed as 203‑70‑42182 / 2087013141) is a wear‑resistant cylindrical sleeve used in Komatsu heavy equipment to support pivoting or rotating connections. It acts as a bearing surface between pins and housings to reduce friction, absorb load, and protect more expensive machine components from wear.

Here’s a general guide for proper installation:

1. Park the machine on level ground and shut off the engine.
2. Support the assembly (such as the arm or linkage) to relieve load on the bushing location.
3. Remove any retaining hardware and extract the worn bushing using a press tool or suitable puller.
4. Clean the bore and mating surfaces to remove debris and corrosion.
5. Press the new 208‑70‑13141 bushing into place, ensuring it seats evenly and squarely.
6. Reassemble related components and torque all fasteners to service manual specifications.

The 208‑70‑13141 bushing is commonly used in Komatsu excavators, especially models such as PC400 series for boom, arm, and linkage pivot points. It’s part of the pin & bushing assemblies that support heavy loads and pivot action in digging and lifting systems. If you are still unsure, reach out to Propel Parts, our team will be happy to help you verify if this part fits your equipment.

Yes. This bushing is manufactured to meet or exceed OEM quality standards, built from durable materials and tested for fit and wear‑resistance. Aftermarket versions are checked to provide similar performance to original Komatsu bushings, helping ensure reliability and long service life.

Bushings should be checked during routine undercarriage, boom, or linkage maintenance. Inspect for signs of excessive movement, scoring, or wear at pivot points. Replace the bushing if it shows significant play or wear, as worn bushings can lead to accelerated wear on pins and housings and reduce machine precision.

Typical indicators include:

1. Loose or sloppy movement in articulated joints
2. Clunking or knocking noises during motion
3. Visible wear, grooves, or flattened surfaces on the bushing
4. Debris or wear particles around the pivot area

A quality bushing ensures smooth pivot motion, reduced friction, and better load distribution at critical joints. Parts that meet or exceed OEM specifications help prevent premature wear of pins and housings, improve machine precision, and extend uptime by reducing unscheduled maintenance.
