Product Description

Komatsu Bearing or bushing 6150-31-3040

1. Product Overview

Komatsu Bearing or bushing 6150-31-3040 is listed under source title “BEARING, CONNECTING ROD 6D125”. It is classified for this pilot as bearing or bushing within the rotating-component support system. The source record does not establish an exact engine model. Confirm the complete engine model, serial number, arrangement, and installed reference before ordering.

2. Function and Operating Principle

A bearing or bushing supports a shaft, journal, gear, connecting rod, or other moving component while controlling alignment and friction. Geometry, clearance, load direction, lubrication, and material are specific to the installed position.

The bearing surface carries load across a controlled contact area and maintains a lubricating film or rolling contact. Correct oil supply, housing fit, shaft condition, and installed clearance are essential.

Knock, rumble, or abnormal rotational noiseMay indicate clearance, lubrication, alignment, or surface damage.
Metal particles in lubricantRequires prompt investigation of bearings and other wear components.
Low oil pressure or elevated temperatureCan involve bearing clearance, pump condition, restriction, or oil quality.
Scoring, wiping, pitting, or discolorationShows distress that requires root-cause analysis.

These observations are inspection triggers rather than a confirmed diagnosis. Evaluate the complete engine system and follow the applicable manufacturer service information.

5. Inspection and Replacement Guidance

  • Identify the exact bearing position and load class.
  • Inspect the shaft or journal, housing, oil passages, and adjacent thrust surfaces.
  • Measure using the manufacturer’s procedure and limits.

6. Information Required Before Ordering

  • Complete engine or equipment model.
  • Engine serial number and arrangement or configuration number.
  • Installed part reference and clear photographs of the identification label.
  • Installation position and related assembly information.

Compatibility notice: Verify 6150-31-3040 against serial-number-specific parts documentation before purchase or installation. Do not select the component by appearance or part-number similarity alone.
