A washer for a crankshaft pulley is a flat or specially shaped component placed under the fastening bolt. Its function is to distribute the clamping force evenly, ensure secure fastening, and help maintain proper alignment of the pulley.
Key specifications include inner and outer diameter, thickness, material (typically hardened steel), and compatibility with the bolt and pulley system. It must withstand high clamping force and engine vibrations.
Replacement is recommended when the washer is worn, deformed, or damaged, or when it is specified as a single-use component during service. A faulty washer can affect bolt tension and pulley stability.
