Teardown and Rebuild Steps

We specialize in the overhaul of your MOOG D633-7381, including the replacement of all necessary seals and worn components.

Independent Repair Facility

Unlike OEM shops, we use our own inventory to handle most rebuilds. That cuts down on lead time and gets your unit back faster.

Frequently Asked Questions

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.

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

If a unit is beyond repair, we explain why and can discuss replacement or exchange options.

Most repairs are completed within 1 to 3 weeks, depending on workload and parts availability.

All repairs come with a 12-month warranty on parts and labor. Contact us for specifics on your unit.

Disassembly and Rebuild Procedure

Every MOOG D633-7381 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Teardown: Every valve is disassembled for internal inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Testing and Bench Verification

With thirteen in-house test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our pre-shipment testing verifies proper functionality.
