Track Link Chain For Komatsu PC120 Excavator

Track Chain for KOMATSU PC120 Excavators

This track chain for KOMATSU PC120 excavators is designed for replacement requirements involving compatible PC120-series crawler undercarriages. It connects the track links through the pin-and-bushing joints, forming the continuous chain assembly that works with the drive sprocket, front idler and track rollers.

For equipment parts distributors, excavator repair workshops and fleet maintenance buyers, accurate model identification is essential when sourcing a replacement track link chain. The current product listing covers multiple PC120 configurations, including PC120-5 and PC120-6 variants. However, different machine versions may use different undercarriage specifications, so compatibility should be confirmed before ordering.

Part Number Cross-Reference and Compatibility

The product listing references the following part numbers and cross-reference codes:

• 203-32-00101

• 203-32-00102

• 203-32-K0020

• 203-32-K0021

• 20E-32-K1150

• KM1262/42

• E4012701M00042

These references should be checked against the original part number and the machine's identification details. Do not assume that every reference is interchangeable across all PC120 models or production versions. If you are replacing an existing track chain, providing the original part number and machine serial number helps establish the correct fitment.

Key Details to Confirm Before Ordering

Before purchasing a KOMATSU PC120 excavator track chain, confirm the following details with your supplier to reduce the risk of ordering an incompatible assembly.

• Machine identification: Provide the complete excavator model designation and serial number, including the relevant model suffix.

• Original part number: Check the parts catalog, existing component markings or maintenance records for the applicable reference number.

• Chain pitch and link count: Verify the pitch and total number of links against the original assembly or the applicable technical specification.

• Chain dimensions: Confirm the required guide width, pin and bushing dimensions, and other installation-critical measurements where necessary.

• Supply configuration: Clarify whether the quotation covers the track chain assembly alone or includes track shoes and associated fastening hardware.

• Order quantity: Specify whether you require one track chain or a complete set for both sides of the excavator.

The current listing specifies a product weight of 266.6 kg. Confirm the applicable weight basis and packaging details with the supplier before using this figure for freight calculations. Chain pitch, link count and other dimensional specifications should likewise be verified for the exact machine configuration rather than assumed from the general PC120 model name.

Track Chain Replacement and Undercarriage Compatibility

When replacing a KOMATSU PC120 track chain, checking the condition of the surrounding undercarriage can help identify related wear that may affect the replacement assembly. Particular attention should be given to the engagement between the chain and drive sprocket, as well as the supporting rollers and idler.

• Drive sprocket engagement: Check sprocket tooth wear and confirm compatibility with the replacement chain.

• Track roller and idler condition: Inspect the supporting components for abnormal wear or alignment issues.

• Pin and bushing wear: Examine the existing chain joints for excessive looseness, wear or other signs of deterioration.

• Track shoe mounting: If existing track shoes will be reused, confirm that their mounting dimensions and fastening arrangement match the replacement chain.

• Track tension: Follow the excavator manufacturer's maintenance procedure when adjusting the installed track.

Replacement Track Chains for Parts Distributors and Repair Workshops

For B2B buyers managing excavator parts inventory, maintenance projects or recurring replacement orders, reliable part identification is important for quotation accuracy and purchasing efficiency. Supplying complete machine information at the inquiry stage can help reduce repeated specification checks and avoid unnecessary ordering delays.

When requesting a quotation for a KOMATSU PC120 track chain, please provide:

• Machine model and serial number.

• Original OEM or reference part number.

• Required quantity and intended replacement scope.

• Available photographs, technical drawings or dimensional measurements.

• Destination country and shipping requirements.

For repeat purchases, keeping the confirmed part number, machine configuration and approved dimensions in your purchasing records can also help maintain consistency across future orders.

Frequently Asked Questions About KOMATSU PC120 Track Chains

Does this track chain fit every KOMATSU PC120 excavator?

Not necessarily. The product listing covers multiple PC120-series configurations, but compatibility may vary by model version and serial number. Confirm the original part number and machine identification details before ordering.

How can I confirm the correct track chain part number for my PC120?

Check the original parts catalog, existing chain markings or equipment maintenance records. If the part number is unavailable, provide the full machine model, serial number and photographs of the existing chain for further identification.

Are track chain part numbers interchangeable between PC120-5 and PC120-6?

Interchangeability should not be assumed based on the PC120 model designation alone. Verify the applicable part number, chain dimensions and undercarriage configuration for the specific machine before confirming a replacement.

Does the track chain include track shoes?

The supply scope should be confirmed when requesting a quotation. Specify whether you need the track chain assembly only or a complete configuration that includes track shoes and fastening hardware.

What information should I provide for a bulk track chain inquiry?

Provide the machine model, serial number, original part number, required quantity and destination country. For orders covering multiple machines, a model-by-model parts list can help clarify fitment requirements and simplify quotation preparation.
