Toyota Camshaft Assembly

The camshaft is a rotating shaft running along the cylinder bank consisting of teardrop-shaped cams, bearings, and bearing journals. Its primary function is to open and close the intake and exhaust cylinder valves at specific times for a specific duration while the engine is operating. The Toyota 5A engine utilizes dual overhead camshafts (DOHC) with separate intake and exhaust camshafts. Constructed from chilled cast iron for wear resistance and dimensional stability under engine operating conditions.
