After a swing motor failure, what hydraulic cleanup should be done before fitting parts?
Short Answer
After a swing motor fails internally, metal debris can remain in the tank, filters, hoses, valve spool, and case-drain circuit. JIAJUE recommends cleaning and inspection before fitting replacement parts, because debris can damage the new motor or make the swing spool stick.
What To Check
- Inspect hydraulic filters, tank bottom, suction screen, pilot filter, case-drain line, and swing hoses for debris.
- Check whether swing pressure is low, inconsistent, or very different from boom and arm relief pressure.
- Before ordering a motor, valve, or filter kit, provide contamination photos, motor tag, machine serial number, and oil condition.
