Fuel Pump

Valve stem seals prevent oil from contaminating the air/fuel mixture in the engine’s combustion chamber. They also prevent intake and exhaust gases from contaminating the oil in the cylinder head and the rest of the engine. Valve stem seams are like any other round seal, only much smaller.

A disk or short cylinder fitting closely within a tube in which it moves up and down against a liquid or gas, used in an internal combustion engine to derive motion, or in a pump to impart motion.

The water pump pushes coolant from the radiator through the coolant system, into the engine and back around to the radiator. The heat that the coolant picked up from the engine is transferred to the air at the radiator. Without the water pump, the coolant just sits in the system.

A glow plug is a heating element that heats incoming fuel and air to encourage efficient fuel combustion in a diesel engine. The fuel combustion starts your engine so that you can drive.

Oil pump gears are powered by the crankshaft and in high horsepower or high revving applications the stock oil pump gears can fail due to the increased harmonics, or oscillating of the gear from the added power and revolutions of the crankshaft.

Piston rings maintain gas compression between the piston and the cylinder wall. Piston rings seal the cylinder so that combustion gas generated at the time of ignition does not leak into the opening between the piston and the cylinder.

The function of a synchronizer is to enable meshing gears to be changed, on a moving vehicle without negative consequences for gears mechanical integrity and interior noise. During synchronization the friction clutch must be disengaged.

A diesel fuel lift pump is a priming pump that transfers fuel from the tank to the fuel injection system. They are called lift pumps, because in most equipment the tank is located below the engine, the fuel has to be lifted up from the tank to the engine.
