The fitting of bearings and camshaft is carried out analogously but in reverse se-
quence to the removal, whereby the following points require special attention:
The camshaft can be installed in every position, however:
D
all parts to be fitted must be clean and undamaged!
D
for the assembly apply oil to bearing shells, thrust bearing ring halves and
camshaft.
D
take care of the designations of reused bearing shells.
D
fit bearing shells, so that their bores provided for dowel pins 17 in the bearing
covers point to the same side (Fig. ’C’ and ’D’).
D
in order to align the bearing shell, centring device 94566b provided for this
purpose is inserted into the corresponding tap hole of the waisted screw as
shown in Fig. ’M’.
D
take care of bearing cover numbering and meshing of dowel pin 17 (Fig. ’D’).
D
apply oil to the threads and seating surfaces of waisted screws 7 and tighten
these equally with a torque of 1450 Nm (for the application of torque amplifier
20 see section 6).
After tightening the waisted screws there must be no clearance at ’x’ (Fig. ’D’,
