The crankshaft main end and big end necks and bearing shells are made in two nominal
sizes.

Crankshafts, the main end and big end necks of which are made of the second nominal
size, have additional marking on the first cheek:

«2

Synchronization of the crankshaft and the HPFIP camshaft angle position
The necessity of synchronization of the crankshaft (torsional vibration damper with pulse
rim) and the HPFIP camshaft (fuel priming pump drive gear with pulse rim) angle posi-
tion may arise as a result of the HPFIP dismantling with its subsequent putting back in
place after current diesel engine repair.
Installation of a silicon damper with a pulse rim and a fuel priming pump drive gear with
a pulse rim maintains synchronization of the crankshaft and the HPFIP camshaft speed
sensors signals with linking the sensors signals to the common initial point of the shafts
positioning at the moment of the 1

cylinder piston coming through its TDC at the com-

pression stroke.
To install the pulse wheels correctly, it is necessary to make a device for fixing the fuel
priming pump drive gear with pulse rim as shown on Fig.1)

Fig. 1 – Device for fixing the fuel priming pump drive gear pulse rim
Remove the cylinder cover cap.
Place the 1

cylinder piston to the TDC position turning the crankshaft clockwise, using

the crankshaft pulley mounting bolt, till the axis of the 16

tooth of the pulse rim “crown”,

located on the torsional vibration damper housing, coincides (counting against the clock
from the pulse rim “crown” breaking segment) with the axis of sensor 2 (Fig.2).
At that, mounting 3 must be coincided with the “TDC” mark on the damper housing.
Make sure the 1

cylinder intake and exhaust valves are closed (there must be a small in-

take and exhaust valves rockers backlash). If the exhaust valve is open, rotate the crank-
shaft by a full turn and check the valves condition once again.
