Teardown and Rebuild Steps

Rebuild Steps

Every MOOG D663-5001 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Teardown: Every valve is disassembled for internal inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Diagnostic Testing

Each MOOG D663-5001 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our pre-shipment testing verifies proper functionality.

Parts and Inventory

With over 17,000 valves in stock, we can often provide faster turnaround by sourcing parts in-house rather than waiting on OEM lead times.
