Crankshaft assembly
Locate the ring (C1) from tool 885035 on the crank-
shaft flange with the correct side of the ring towards
the sealing ring. If the sealing ring is to be installed
in the front position (see paragraph 4), install the
socket with the end with diameter markings turned
to the sealing ring. Install the plate (C2) from the
tool 885035 and use the locknuts to tighten the
studs in the crankshaft flange. Slacken off the lock-
nuts, ensure that the plate is installed perpendicular
to the crankshaft and use the front nuts to press the
sealing ring into position. The nuts must be tight-
ened in stages and evenly.

Crankshaft axial clearance,
checking (14A-04)
The axial play of the crankshaft is controlled by two
sectioned thrust washers on each side of the cen-
tral main bearing (B). The axial clearance can be
checked with a feeler gauge between a thrust wash-
er and the crankshaft. A better method is to use a
dial indicator and measure axial clearance against
one of the crankshaft ends (A). For the correct axial
clearance, see Workshop Manual, “Technical data”.
