The camshafts are driven by separate chains from the crankshaft drive sprocket.
The engine features a balance shaft, which reduces unwanted vibrations for the engine. The shaft is mounted above the camshaft on the front cylinder head and is driven by a separate chain from the camshaft sprocket.
The engine is lubricated by an oil pump located in the oil pan. The pump is driven by a separate chain from the sprocket on the crankshaft (see illustration 1.0a).

The intake and exhaust valves of all engines are actuated by camshaft cams via hydraulic tappets, which automatically adjust the valve clearances and keep them constant. For this reason, valve clearance adjustment is not required during vehicle maintenance.
Plate A with the engine number and designation is located on the left side of the right cylinder block (see illustration 1.0b).
