Powertrain Engines

• The crankshaft gear and the fuel high-pressure pump gear are equipped with friction

gears. The spring-loaded friction gears eliminate the backlash between the meshing

gears, reducing gear noise.

NOTE: Before removing the fuel high-pressure pump gear, the friction gear must be fixed to

the fuel high-pressure pump gear using a detent bolt (M6 x 1.0, length approx. 16

mm) to prevent it from rotating due to the spring force.
