Rebuild Steps

The repair process for the MOOG 73-102A includes disassembly, diagnostic review, and replacement of failed seals, spools, or other elements. Final assembly includes leak and function testing.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Leak and Performance Testing

Each MOOG 73-102A is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our functional testing verifies proper functionality.
