For Komatsu 6D170 S6D170 Engine Parts 6162-23-2210 Cylinder Liner

6162-23-2210 is a replacement cylinder liner used in selected Komatsu 6D170 and S6D170 diesel engine applications. It is intended for engine overhaul and cylinder block rebuilding where the liner specification matches the original Komatsu part configuration.

Because Komatsu 170-series engines were used across different machine types and production versions, buyers should confirm the engine model, machine model and serial number before ordering.

Komatsu 6162-23-2210 Cylinder Liner Specifications

Dimensions and application should be verified against the original liner, engine specification or Komatsu parts information before ordering.

How to Confirm the Correct Cylinder Liner

Before ordering a Komatsu engine cylinder liner, please provide as much of the following information as possible:

• Original part number

• Engine model

• Machine model

• Machine serial number

• Photos of the removed cylinder liner

• Liner bore and overall dimensions, if available

• Engine nameplate photo

For older Komatsu equipment, checking the engine version and serial number is especially important because different engine generations may use similar-looking liners with different dimensions or sealing arrangements.

When Should a Cylinder Liner Be Replaced?

Cylinder liners are normally inspected during engine overhaul or when abnormal cylinder wear is found.

Replacement may be required when inspection identifies:

• Excessive cylinder bore wear

• Scoring or deep vertical scratches

• Cracks or physical damage

• Corrosion or pitting

• Poor piston-ring sealing

• Abnormal oil consumption

• Reduced compression

• Damage discovered during engine rebuilding

The cylinder block, piston, piston rings and liner sealing surfaces should also be inspected before installation.

Installation and Inspection Notes

Before installing a replacement cylinder liner:

1. Clean the cylinder block liner seating area completely.

2. Inspect the block for corrosion, cracks and damaged seating surfaces.

3. Compare the new liner dimensions with the removed component.

4. Check the applicable seals or O-rings according to the engine configuration.

5. Measure liner protrusion according to the engine service specification.

6. Inspect piston and piston-ring condition before final assembly.

Installation dimensions and procedures should follow the applicable Komatsu engine service information.
