Engine thrust washers are critical components in internal combustion engines, designed to manage axial loads and maintain proper alignment of rotating parts. These washers play a vital role in ensuring the smooth operation of the engine, particularly in the context of the crankshaft and camshaft assemblies.

The primary function of thrust washers is to absorb and distribute axial forces generated during engine operation. These forces can arise from various sources, including the movement of the crankshaft and the forces exerted by the connecting rods during combustion. Thrust washers help prevent excessive movement of the crankshaft in the axial direction, ensuring that it remains properly aligned within the engine block.
By providing a stable surface for the crankshaft to rest against, thrust washers help maintain the correct clearance between the crankshaft and other engine components. This is crucial for preventing wear and tear, which can lead to engine failure if not properly managed.

Proper lubrication is essential for the effective functioning of thrust washers. Engine oil circulates through the engine, providing a protective film that reduces friction and wear on the washer surfaces. Regular oil changes and using the correct type of oil are crucial for maintaining the health of thrust washers and the overall engine.

Over time, camshaft bearings can experience wear due to factors such as inadequate lubrication, contamination, or excessive load. Symptoms of failing camshaft bearings may include unusual noises, decreased engine performance, and erratic valve operation. Regular maintenance, including oil changes and inspections, can help identify potential issues early, preventing more severe engine damage.
