The 319006819 harness is manufactured using automated wire processing and assembly techniques that ensure consistent cut lengths, strip quality, and crimp integrity. Each terminal is crimped with a calibrated press that monitors force and position to guarantee a gas‑tight, low‑resistance connection that meets or exceeds OEM specifications. Connectors are assembled with factory‑specified seals and locking wedges, ensuring proper ingress protection and secure mating in grease‑rich environments.
The entire harness is then subjected to a 100% continuity and insulation resistance test to verify that every circuit is correctly routed and free of shorts or opens. After electrical testing, the harness is routed through a dimensional check fixture that confirms overall length, branch positions, and connector orientations match the original design. Protective sleeving and grommets are applied at specified locations, and all tie‑wraps are tensioned to a controlled torque.
The wire insulation is specifically formulated to resist lithium grease, gear oil, and other lubricants, ensuring that the harness maintains its electrical integrity even when exposed to grease leaks or spills. The outer loom is manufactured from grease‑resistant material that provides an additional barrier against chemical attack.
Sample harnesses from each production run undergo thermal cycling, flex testing (minimum 500,000 cycles), and grease immersion testing to validate long‑term durability and performance under harsh environmental conditions. The result is a secondary centralized filling wiring harness that delivers consistent, reliable electrical performance throughout the service life of your XCMG excavator.
The secondary centralized lubrication system is responsible for delivering precise amounts of grease to additional pivot points on the excavator, including extended boom sections, auxiliary attachments, and high‑wear areas that require supplemental lubrication. Proper lubrication reduces friction, prevents wear, and extends the service life of these components. The electrical system that controls the secondary lubrication pump and valves relies on the integrity of the wiring harness.
The 319006819 harness ensures that the auxiliary lubrication pump receives power and control signals reliably, enabling consistent grease delivery according to the machine’s programmed schedule. It also carries feedback from pressure and level sensors, allowing the control system to monitor system health and alert the operator to low grease levels or blockages.
Field data from heavy construction and mining operations shows that machines equipped with genuine XCMG secondary lubrication harnesses experience fewer lubrication system faults and reduced diagnostic time, improving machine availability and reducing component wear. The harness’s robust construction and sealed connectors protect against moisture, dust, and grease ingress, ensuring reliable operation even in the most demanding job site conditions.

By maintaining secure, reliable connectivity, this harness plays a vital role in ensuring safe, productive excavator operation.
The 319006819 centralized filling wiring harness is designed for a direct plug‑and‑play replacement. Before installation, disconnect the battery and ensure the secondary lubrication system is depressurised and cool. Remove the old harness, carefully noting the routing and all connector positions. Clean each connector receptacle and mounting clip location to ensure a clean, reliable mating surface.
Install the new 319006819 harness by laying it along the original routing path, securing it with the pre‑installed clips and tie‑wraps. Connect each branch to its corresponding component – the auxiliary grease pump, secondary solenoid valves, pressure transducers, and level sensors – ensuring that the connectors click fully into place and that the locking wedges are engaged. After all connections are made, route the harness carefully away from hot engine surfaces and moving parts.
During routine maintenance, inspect the harness for any signs of wear, chafing, or connector corrosion. Check that all tie‑wraps remain secure and that the harness is not under tension or rubbing against sharp edges. Periodic cleaning of the connectors and application of dielectric grease will help maintain low contact resistance and prevent corrosion.
