Shim for the starter motor at the transmission housing of classic Citroën vehicles. Used on models with similar engine mounting and casing. The shim corrects alignment between starter motor and flywheel. This reduces mechanical stress and supports reliable gear engagement. The dimensions fit small diameter shafts and bushings. The thickness allows accurate setting of axial distance in the assembly. The material is suitable for long term use in the engine bay. The ring is applied during service, overhaul or restoration of older vehicles with a comparable design and similar starter drive layout.
