20Y-06-31470 Wiring Harness for Komatsu PC200 PC210 PC220 PC270 Excavator Part

Part number 20Y-06-31470 is the Wiring Harness used on Komatsu PC200, PC210, PC220, PC270 excavators. This aftermarket replacement from TOPARTS is designed to fit in place of the original without cutting, splicing or rerouting.

How It Works on Your Machine

Wiring harnesses rarely fail all at once. They wear out gradually through heat, vibration and abrasion until a connection becomes unreliable. Replacing the Wiring Harness restores the circuit to as-new condition in one job.

This harness carries power and control signals between the components it connects on the excavator, keeping the related circuits running reliably under everyday working conditions.

Komatsu excavators are known for long service lives, and many keep working well past the point where their original wiring has aged. A new harness is often the key to keeping an older Komatsu reliable.

Installation Guide

  1. Disconnect the battery before starting work.
  2. Take photos and label connectors before removing the old harness.
  3. Secure the new harness with the original clips and keep it away from heat and sharp edges.
  4. Test all related functions before refitting covers.

Frequently Asked Questions

How long does shipping take?
Orders are shipped by express courier such as DHL, FedEx, UPS or TNT, and you will receive a tracking number by email as soon as your parcel leaves our warehouse.

Is this a genuine or aftermarket part?
Please see the Condition line in the specifications above. Every part is checked for fit and continuity before shipping.

Do I need special tools to install it?
Standard hand tools are usually enough. Labelling connectors and taking photos before removal makes the job much easier.

How to Tell It Is Time for a New One

You may notice:

  • Signs of heat damage or melted sections
  • Recurring fault codes linked to this circuit
  • Cracked, hardened or chafed insulation
  • Electrical functions working intermittently

When diagnostics point to a circuit fault rather than a failed component, replacing the wiring is often the most cost-effective repair.

Why a New Harness Beats Patching

Patching wiring takes time: tracing the fault, cutting, crimping and sealing, often in an awkward position. When the insulation is hardened along the whole length, that time is better spent fitting a new harness that solves every weak spot at once.

Reducing Downtime

Electrical problems tend to get worse rather than better. Replacing a deteriorating harness at a planned service interval is far cheaper than dealing with a breakdown in the middle of a job, especially on remote sites.
