Lyman Designs MK 4 Power Feed
 |
Lyman MK 4 Power Feed is a 13‑speed gear drive unit used on Bridgeport milling machines for table feed control. Common failure points in this class of power feeds include worn or broken gear teeth, motor windings that have lost insulation, and damaged overload protection relays or contacts. For first‑check diagnostics, verify the unit’s input voltage and continuity to the motor; inspect the drive gears and motor shaft for wear or binding; and review any error codes or indicator lights on the control panel before proceeding with deeper electrical or mechanical repairs.[oss-gpt-20b] |
