Durco Units We Rebuild
We work on the full range of Durco equipment — from legacy units to current production models.
Our Durco Rebuild Process
Every Durco rebuild follows a documented process — from teardown through load test. No shortcuts, no guesswork.
Teardown & Inspection
Complete disassembly with photographic documentation. Every gear, bearing, shaft, seal, and housing is inspected and measured against OEM specifications.
Failure Analysis
We identify the root cause — not just the symptom. Overloading, misalignment, lubrication failure, contamination, and fatigue are all documented before rebuild begins.
Precision Machining
Worn bores are re-machined to OEM tolerances. Shafts are repaired or replaced. Housings are cleaned, inspected for cracks, and restored to spec.
Component Replacement
Worn or damaged components are replaced — gears cut in-house to AGMA standards, bearings and seals replaced with OEM-equivalent or upgraded parts.
Assembly
Rebuilt units are assembled to OEM torque specs with fresh lubricant and new seals throughout.
Load Testing
Every major rebuild is load-tested on our 500 HP test stand. Vibration, temperature, and flow are verified before shipment.
