BH604201L is the alternator pivot bolt for the Land Rover Series 3 fitted with the 3.5 V8 petrol engine, securing the alternator to its mounting bracket and providing the pivot point around which belt tension is adjusted. This bolt bears the load of alternator movement during tensioning and must maintain clamping force under sustained engine vibration. Using the correct replacement bolt ensures proper thread engagement with the bracket and prevents alternator misalignment or slippage under load.
