Repair Procedure

Each MOOG J761-004 undergoes reconditioning — disassembly, parts replacement, reassembly, and bench testing before shipment.

Key Details

We’ve serviced hundreds of MOOG J761-004 units over the years. Each one goes through the same controlled teardown, parts replacement, and testing process.

Frequently Asked Questions

Even if the tag is worn off, we can often match the unit based on shape, size, and internal configuration.

We confirm next steps with you if a unit can’t be rebuilt. No work proceeds without your approval.

Part of our intake includes troubleshooting to determine the failure point. We report findings before proceeding.

We recommend sending pictures, especially if the model number is unclear or there is visible damage.

If the main housing or board is intact, repair is usually the better option. We can restore most units to working condition with tested parts.

About Our Shop

NC Servo Tech specializes in both valves and electronic controls, which lets us operate without the delays of OEM service centers.

How We Rebuild This Valve

Each valve goes through teardown to expose wear and buildup. After mineral bath cleaning, we replace damaged parts and reassemble the unit to spec.

  • Teardown: Every valve is disassembled for internal inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Leak and Performance Testing

NC Servo Tech operates our 13-stand test facility, including setups for proportional and servo valves. Every valve goes through performance and leak testing using industry-standard fluids including MIL-5606 and Skydrol. Our pre-shipment testing verifies proper functionality.
