Track Chain for KOMATSU PC300-6 Excavators – 48-Link Assembly

This track chain for KOMATSU PC300-6 excavators is a model-specific undercarriage replacement option featuring a 48-link configuration. It is intended for buyers identifying a replacement track chain by machine model, link quantity and reference part numbers. For excavator parts distributors, equipment maintenance teams and repair workshops, confirming these details before purchasing helps reduce the risk of ordering an incompatible assembly.

The track chain forms the continuous linked structure of the crawler undercarriage. Its pins and bushings connect individual links, allowing the assembly to articulate as it travels around the drive sprocket and front idler. The chain also works with the track rollers and track shoes as part of the complete undercarriage system.

When sourcing a KOMATSU PC300-6 track chain assembly, the 48-link configuration is an important identification reference, but it should not be used as the sole basis for confirming fitment. The machine's serial number, original part reference, chain pitch and joint dimensions should also be checked.

PC300-6 Track Chain Specifications and Part Number References

The following identification information is associated with this product listing. Buyers should cross-check the references against the original machine parts catalog before confirming an order.

Part number verification: The references above should be treated as identification and cross-reference information, not as confirmation that every number is interchangeable across all machine configurations. Confirm the applicable reference for your specific PC300-6 excavator before placing an order.

How to Confirm the Correct 48-Link Track Chain

For a replacement order, the link count is only one part of the identification process. The following checks help establish whether the proposed track chain matches the machine's existing undercarriage.

1. Verify the Machine Version and Serial Number

Start with the complete KOMATSU PC300-6 model designation and machine serial number, where available. Production variations and previous undercarriage replacements can affect the parts required. The original equipment parts catalog or maintenance records can help establish the correct reference.

2. Confirm the 48-Link Configuration

Check the number of links on the existing assembly and compare it with the replacement requirement. Confirm whether the specified quantity refers to one complete track chain and whether the order covers one side of the machine or both sides. Do not assume that matching link counts guarantee dimensional compatibility.

3. Check Chain Pitch and Joint Dimensions

Track pitch determines the spacing between adjacent chain joints and affects engagement with the drive sprocket. Pin diameter, bushing dimensions and joint construction also influence compatibility. These details should be confirmed against the applicable technical specification rather than estimated from the machine model alone.

4. Clarify the Track Chain Supply Scope

Confirm whether the requested product is a complete track chain assembly or individual track links for repair. If the existing track shoes will be reused, verify their mounting-hole arrangement, bolt spacing and compatibility with the replacement chain. If new shoes or fastening hardware are needed, specify whether they should be included in the quotation.

Undercarriage Components to Check Before PC300-6 Track Chain Replacement

Replacing the track chain is also an opportunity to inspect the adjoining components that guide, support and drive the crawler assembly. Their condition can affect the installation and service performance of the replacement chain.

• Drive sprocket: Inspect tooth wear and verify that the sprocket profile is compatible with the replacement chain.

• Track rollers: Check for abnormal wear, damage and uneven support along the chain's running path.

• Front idler: Inspect the guiding surface and alignment for visible wear or damage.

• Track shoes: Verify the mounting dimensions and condition of the shoes if they will be transferred to the new assembly.

• Track adjustment system: Check its condition and follow the machine manufacturer's procedure for setting the correct track tension after installation.

Worn adjacent components can affect chain engagement and contribute to uneven wear. The decision to replace additional parts should be based on inspection findings and the applicable service limits, rather than automatically replacing every undercarriage component at the same time.

Replacement Planning for PC300-6 Parts Distributors and Maintenance Teams

For B2B buyers handling multiple excavators, scheduled maintenance or recurring spare parts orders, accurate identification can simplify quotation and inventory management. A confirmed track chain reference also helps distinguish the required PC300-6 configuration from other PC300-series models.

When requesting a quotation, prepare the following details where available:

• Complete machine model and serial number.

• Original part number or existing supplier reference.

• Confirmation of the required 48-link configuration.

• Known chain pitch and pin-and-bushing dimensions.

• Required quantity and whether one or both sides of the machine need replacement.

• Whether track shoes and associated fastening hardware are required.

• Destination country and shipping requirements.

For repeat orders, retain the confirmed machine identification details and approved part references in your purchasing records. This makes it easier to review subsequent orders and helps reduce the risk of mixing different undercarriage configurations in stock.

Frequently Asked Questions About KOMATSU PC300-6 Track Chains

What does 48-link mean for a PC300-6 track chain?

It identifies the specified link quantity of the track chain assembly. However, link count alone does not establish fitment. The chain pitch, joint dimensions, machine version and other installation requirements must also match.

Are part numbers 207-32-00151 and 207-32-00310 interchangeable?

Interchangeability should be verified against the applicable KOMATSU parts catalog and machine serial number. Although both numbers appear in this product's title, buyers should confirm the correct replacement reference for their particular machine before ordering.

Can this 48-link track chain fit other PC300-series excavators?

Compatibility with other PC300-series models should not be assumed. Different model versions may use different link quantities, pitches, joint configurations or other undercarriage dimensions. Confirm the required specifications for each machine individually.

Can I request a quotation without knowing all the track chain dimensions?

Yes. Start by providing the machine model, serial number if available, original part number and required quantity. Photographs of the existing chain, dimensional drawings or additional measurements can help clarify the required configuration if the original reference is unavailable.

Should I order track shoes together with the PC300-6 track chain?

That depends on the condition of the existing shoes and the intended replacement scope. If the shoes are being reused, verify their mounting compatibility with the replacement chain. If they also require replacement, specify the required shoe configuration and confirm whether the shoes and fastening hardware are included in the quotation.
