| Policy Point | Terms |
|---|---|
| Merchant Return Policy | All sales are final. No returns or exchanges. A wiring harness is a critical electronic component. Once departed from our controlled quality environment, we cannot verify it has not been partially installed, contaminated, or damaged. This ensures every customer receives a brand-new, untouched product. |
| DOA Quality Guarantee | Complete replacement for manufacturing defects reported within 7 calendar days of delivery. Harness must be in original, uninstalled condition. Physical damage from cutting, stretching, crushing, or incorrect installation voids the guarantee. |
| Pre-Shipment Confirmation | We send high-resolution photos of your exact harness laid out on our jig board for your written approval. No shipment is released without your explicit confirmation. |
Q1: What are the symptoms of a failing 0004911 main chassis harness on my ZAXIS 200?
A: Common symptoms include multiple unrelated fault codes appearing simultaneously, intermittent ECM or pump controller communication loss, specific hydraulic functions becoming slow or unresponsive, the monitor display flickering or showing erratic data, random engine derate or shutdown, visible chafing or melted insulation, green corrosion at connector backshells, and sensor values dropping out during a wiggle test with diagnostic software connected.
Q2: Is this harness compatible with the ZAXIS 200LC long carriage model?
A: In most cases, yes. The ZAXIS 200 and ZAXIS 200LC share the same upper structure and electrical architecture. The main chassis harness is typically identical. We will verify using your machine's complete serial number during pre-shipment confirmation.
Q3: What is the relationship between part numbers 0004911 and 0004912?
A: These are closely related part numbers within the Hitachi ZAXIS harness family. The 0004911 is specifically for the ZAXIS 200 platform, while the 0004912 is for the larger ZAXIS 230LC/270 machines. Our technical team will confirm the correct number for your specific machine.
Q4: Do you accept a trial order of a single harness?
A: Yes, absolutely. We welcome and encourage trial orders for single units. We understand the importance of verifying product quality, fit, and performance before committing to larger quantities.
Q5: What certifications does COGENG hold?
A: COGENG is an ISO 9001 certified manufacturer. Our quality management system ensures consistent manufacturing processes, rigorous multi-stage inspection protocols, and complete batch traceability for every harness produced.
