Disassembling and assembling the starter (BMW 5 Series E12)

When disassembling and assembling the starter, follow the exploded view provided. Check:

• condition and degree of wear of the brushes. The brushes must move freely in the grooves of the brush holders.
• brushes fit to the collector and spring pressure on the brushes;
• appearance of the manifold. The manifold can only be cleaned with a clean rag soaked in gasoline or trichloroethylene. Sand the manifold only with fine-grained sandpaper. It is prohibited to use emery cloth for this purpose;
• condition of self-lubricating bushings of covers. Before installing new bushings, immerse them for at least 20 minutes in engine oil (SAE 30/40);
• appearance of the anchor and stator. Make sure that their windings have no breaks or signs of burning.
