General
The gear drive is located on the output side of the engine. This
design allows the majority of major assemblies to be placed on the
engine side.
The following components and major assemblies are driven by the
crankshaft (1) via the gear drive:
f
Oil pump (2)
f
Double intermediate gear (3)
f
Compressor (4)
f
Intermediate gear (5)
f
Power steering pump (6)
f
Fuel high pressure pump (7)
f
Double intermediate gear (8)
f
Intermediate gear (9)
f
Exhaust camshaft (10)
f
Intake camshaft (11)
The driving power for the individual major assemblies and
components is spatially transferred to the following levels:
f
Level 1 (A)
f
Level 2 (B)
f
Level 3 (C)
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Level 1 (A)
Level 1 (C) includes the drive gear for the crankshaft (1), the drive
gear for the oil pump (2) and the double intermediate wheel (3).
The gears for level 1 (A) are helically geared.
Level 2 (B)
Level 2 (B) includes the intermediate gear (5), the double
intermediate gear (8) as well as the drive gear for the fuel high
>
pressure pump (7) and the compressor (4).
The gears for level 2 (A) are straight geared.
Level 3 (C)
Level 3 (C) includes the intermediate gear (9), the drive gear for
the exhaust camshaft (10) and the drive gear for the intake
camshaft (11).
The gears for level 3 (A) are straight geared.

Torque curve
The drive for the gear drive takes place over the crankshaft (1):
The drive gear for the crankshaft (1) drives the gears of Level 1 (A),
that is the drive gear for the oil pump (2) and the double
intermediate wheel (3).
The gears for
Level 2 (B), that is the drive gear for the compressor (4) and the
intermediate gear (5) are driven over the double intermediate
gear (3), and the double intermediate gear (8) and the drive gear
for the fuel high
>
pressure pump (7) are driven over the
intermediate gear (5).
The double intermediate gear (8) drives the gears for level 3 (C),
that is the intermediate gear (9), and via the intermediate gear
(9), the drive gear of the exhaust camshaft (10) and the drive gear
of the intake camshafts (11).
The power steering pump (6) is driven over a driver by the fuel
high
>
pressure pump (7).

The gear drive can be adjusted using a suitable special tool.
