14X-71-12240 Komatsu Bushing

The 14X‑71‑12240 bushing is a wear‑resistant sleeve designed for use in Komatsu heavy machinery. It provides a smooth bearing surface between moving parts (such as pins and linkages), reducing friction and wear while protecting the machine’s structural components.

Here’s a general installation overview:

1. Park the machine on level ground and turn off the engine before servicing.
2. Support the relevant assembly (e.g., linkage or pivot arm) to remove load from the bushing area.
3. Remove retaining hardware and carefully extract the worn bushing.
4. Clean the bore and mating surfaces of dirt, debris, and corrosion.
5. Press the new 14X‑71‑12240 bushing into place using a bearing press or suitable driver, ensuring it seats squarely and flush.
6. Reassemble all components and confirm smooth movement.

The 14X‑71‑12240 bushing is compatible with a range of Komatsu dozers and other heavy equipment where this part number is specified. It is often used in blade, linkage, or pivot assemblies on machines such as D60, D61, D63, D65, D65EX, D65PX, D65WX, D85E, and similar models. Always check your parts manual to verify compatibility before ordering. Check your manual or reach out to Propel Parts for help verifying fitment.

Yes. This bushing is manufactured to meet or exceed OEM quality standards to match the fit and durability of the original Komatsu part. It is made from wear‑resistant materials and undergoes quality checks to ensure reliable performance under demanding working conditions.

Inspect bushings during routine maintenance or anytime related assemblies are serviced. Look for signs of excessive wear, looseness, or play in pivot joints. Replace the bushing if substantial wear or movement is detected to protect pins, housings, and other components from premature failure.

Typical indicators include:

1. Excessive play or looseness in pivot joints
2. Grinding or knocking noises during movement
3. Visible grooves or deformation on the worn surface
4. Metal debris around the pivot area

A quality bushing ensures smooth motion, reduced friction, and proper load distribution across moving parts. Parts that meet or exceed OEM specifications help extend machine uptime, reduce maintenance costs, and improve stability especially in heavy‑duty applications with high loads and frequent motion.
