WASHER - DRIVE UNIT LOCK (Raymond RA11828-05)

A worn drive unit lock washer can allow fastener loosening under vibration, risking component separation. This aftermarket replacement part references Raymond catalog number RA11828-05. The washer type provides a plain mechanical function: it creates tension between a fastener and its mating surface. A generic failure consequence is that a collapsed or deformed washer reduces clamping force, leading to joint slippage. In a usage context, such washers are often encountered during drive unit disassembly and reassembly. The part is a hardware washer, not a specialty fastener. Verify the serial number or application, then call (562) 693-7748.
