This lock washer is a crucial fastener component used in various Volvo engine and chassis applications to prevent loosening under vibration. It works by creating tension between the bolt head or nut and the surface, resisting rotational movement. A failed or missing lock washer can lead to fasteners vibrating loose, potentially causing component misalignment or failure.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The primary symptom of a missing or failed lock washer is the gradual loosening of the associated fastener. If left unaddressed, this can lead to increased vibration and potential misalignment of the connected components. The worst consequence is the complete detachment of a critical part, leading to operational failure and potential damage.
Always ensure the mating surfaces are clean and free of rust or debris before installing the lock washer. Do not reuse a lock washer that has been significantly deformed or flattened during previous use.
When replacing fasteners secured by lock washers, inspect the threads of both the bolt and the tapped hole for damage or wear.
