TECHNICAL DISCUSSION ON REPAIRING AND REWINDING MOTORS FOR YAESU G5400 / KR5400 ROTORS
AMSAT-BB MAILING LIST / AUTHOR: JOHN (M5ET) - REPLY TO JIM (WD0E)
DATE: OCTOBER 23, 2026
ISSUED VIA BPQ32 NODE HP2DFA-5 IN PANAMA
==================================================
1. OVERVIEW & G5400 MOTOR ISSUE
==================================================
JIM WHITE (WD0E) POSTED ON AMSAT-BB REGARDING TWO
YAESU G5400 ELEVATION ROTORS TOLD BY YAESU SERVICE
THAT REPLACEMENT MOTORS ARE UNAVAILABLE, A COMMON
ISSUE WITH NO DIRECT AFTERMARKET REPLACEMENTS FOUND.
==================================================
2. REPAIR & REWINDING SOLUTIONS
==================================================
JOHN (M5ET) NOTED THE OLD G5400 IS LARGELY IDENTICAL
TO KENPRO'S KR5400 (PAIRING A KR500 ELEVATION AND
KR400 AZIMUTH ROTOR).
- **MANUAL REWINDING**: IF A MOTOR WINDING IS BAD,
IT CAN LIKELY BE REWOUND BY HAND TO SALVAGE THE UNIT.
