Parts in the timing case
The timing case is an integral part of the right-hand engine case on Harley-Davidson air-cooled V engines. The timing case contains the gears for the camshafts, the oil pump drive and the ignition and, of course, for the generator, as well as the bearing bushes or needle bearings for the gears and shafts. In the Twin Cam and Milwaukee Eight OHV engines, this also includes the timing chains. And on all models, the engine is vented via the timing case. The timing case is closed by the timing cover.
