Weak charging, a flickering charging control lamp or noise from the generator are common symptoms that can point to worn brushes or tired bearings – typical checkpoints when the generator on an early 140 with B18B is to be reconditioned. This category gathers wear parts and mounting components that fit the generator with code 238621, a 12-volt system on twin-carburetor B18B cars.

The group includes brush sets, ball bearings and the flywheel bearing for the generator itself, the voltage regulator, plus nuts and spring washers for mounting and connections. During an overhaul, the brush length and spring pressure as well as the bearing play are the first points to measure. Since 238621 is a specific design, it is worth checking the generator code against the car before selecting parts, so that the brush holder and bearing dimensions match.
