This crankshaft thrust shim is designed for specific Citroën engines. The shim limits axial play of the crankshaft and supports correct alignment of rotating parts. With its fixed thickness, the part contributes to constant bearing clearance and prevents excessive movement. Its dimensions match the crankcase and bearing seat. The material is selected for even wear and stable operation inside the engine. The shim is used during overhaul or repair of the crankshaft bearing system and forms a defined element in the bearing stack. This keeps crankshaft positioning stable under changing mechanical load and operating conditions.
