Primary drive is provided by a toothed timing belt from the crankshaft to the exhaust camshaft gears of each cylinder bank via two idler pulleys and a tensioner.

Timing belt adjustment is carried out by the eccentric type tensioner mounted on the right front face of the cylinder block.

The primary drive cover is secured to the front of the cylinder block, cylinder heads, intake manifolds and oil pump housing. The cover is sealed with a gasket. A bridge piece closes the back of the cover in between the cylinder heads.
