Caterpillar Engine Cooling System Components. Water pump. Oil cooler. Passages through block and . Temperature regulator and regulator housing. Radiator. Pressure cap. Hoses and pipes. Caterpillar Engine Cooling System. Coolent flows through the passages in the cylinder block in to the cylinder head. Water seals between the head and cylinder block prevent coolent leaks. Some engines have water ferrules to direct coolant to critical areas. Caterpillar  Engine  Cylinder  cooling  system. Coolant flows arround the cylinder liners. Absorbs heat from the combustion chamber. Prevents break down of oil film between pistons and cylinder liners.

Valve System Components.  The valve system components control the flow of the inlet air and of the fuel into the cylinders and the flow of exhaust gas out of the cylinders during engine operation. (2) Valve bridge. (3) Valve rotator. (4) Valve spring. (5) Pushrod. (6) Valve. (7) Cam follower. (8) Camshaft lobe. The crankshaftt gear drives the camshaft gears through idler gears. The camshafts must be timed to the crankshaft in order to get the correct relation between the movement of the piston and movement of the valves. The camshafts have two camshaft lobes (8) for each cylinder. As the camshaft turns, the camshaft lobe causes cam follower (7) and pushrod (5) to move up and down. The pushrod moves rocker arm (1). Movement of the rocker arm causes valve bridge (2) to move up and down on a dowel in the cylinder head. This movement operates valves (6). The valve bridge enables one rocker arm to operate two valves simultaneously. There are two inlet valves and two ...
