LOCKWASHER (Komatsu KO01602-21142)

KO01602-21142: A worn lockwasher can allow threaded fasteners to loosen under vibration. This aftermarket replacement part references the Komatsu catalog number KO01602-21142. A lockwasher is a type of hardware washer that creates tension between a nut and the mating surface. Its plain mechanical function is to resist rotational loosening by biting into the fastener and the joint. A common failure consequence is that a missing or collapsed lockwasher leads to fastener back-out and joint separation. During routine disassembly, a lockwasher may appear flattened or cracked and should be replaced. Verify the serial number or application, then call (562) 693-7748.
