A: The small intermediate gear that drives the power
steering and the fuel feed pump is supported by a
twin-race ball bearing (1) and is held in place by a bolt
(2). The bolt passes through the bearing and holds it
against the timing plate and is fastened in the cylinder
block.
B: The lower intermediate gear comprises two gear-
wheels assembled together. The gearwheels are pre-
installed on a hub (4) and supported by two conical
roller bearings (5). The locating sleeve (6) guides the
intermediate gear in the timing plate.
This intermediate gear with two gear wheels, bearing
and hub is a complete unit that cannot be disassem-
bled but must be replaced as a complete assem-
bly.

Engine timing intermediate gear
C: The adjustable intermediate gear is supported by
a bushing (7) on the hub (8). The bushing and the
thrust washer (9) are pressure lubricated via a duct
(10) that runs between the cylinder block and the tim-
ing plate. A locating pin (11) in the lower part of the
hub keeps gear lash constant between the two gear
lash measurement. Therefore only the gear lash
against the camshaft gear need be set when adjust-
ing.
