General information about six-cylinder engines (Nissan Terrano 1)

This Section describes the types of repair work performed on V6 engines that are carried out directly on the vehicle. All repair operations described below assume that the engine is installed on the vehicle.

The engine has a V-shaped arrangement of cylinders and 2 heads (one for 3 cylinders), located at an angle of 60°. Both camshafts (one in each head) have a toothed belt drive. The belt tension is adjusted by a spring-loaded roller with an eccentric. The force from the camshaft is transmitted to the valve via rocker arms mounted on the rollers and hydraulic tappets. The valves are self-adjusting. Each cylinder has 1 intake valve and 1 exhaust valve. The crankshaft is cast from malleable cast iron. The crankshaft main bearing caps are cast into a single frame, which is attached to the crankshaft housing (cylinder block). The ignition distributor is driven by a spiral gear mounted on the left camshaft nose. The oil pump drive gear is mounted on the crankshaft nose.
