The Caterpillar Cat 235C EXCAVATOR (Prefix 5AF) Service Repair Manual (5AF00001 and Up) provides information on engine configuration, which is a four-stroke, straight six cylinder, turbocharged diesel engine with charge air cooling and wet cylinder liners. It uses Common Rail fuel injection controlled by an electronic control unit. The cylinders are numbered consecutively from the flywheel end and the engine rotates counterclockwise. The engine identification plate provides the model and serial number. Key components include the air inlet, alternator, fuel pump, and exhaust manifold. Removing and replacing the engine requires draining fluids, disconnecting components, lifting out the old engine, and installing the new engine by reconnecting components.
