WASHER - LOCK (Komatsu KO01601-11846)

A worn lock washer can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO01601-11846. The washer type provides a plain mechanical function by creating tension between a nut and the mating surface. A generic failure consequence of a degraded lock washer is that the fastener may back off, causing unintended movement or noise in the assembly. During routine service, a lock washer should be replaced if it shows deformation or loss of spring tension. Verify the serial number or application, then call (562) 693-7748.
