102. Fit the big end bearings so that the markings on
the cap agree with markings on the connecting
rods. Oil the threads and tighten with a torque
wrench. The tightening torque is: 63 Nm (6.3
kpm). (46.4 lbf. ft.). NOTE! When fitting new
screws the tightening torque is 70 Nm (7.0 kpm).
(51.6 lbf. ft.). Then check that the crankshaft can

Oil pump
103. Fit a new sealing ring on the pipe for the oilpump.
Where necessary also change the sealing ring at
the other end of the pipe. Fit the pump. Make sure
that the seals are not damaged. The pump is to
mate properly with the crankcase before the
screws are tightened.
104. Fit a new sealing ring in the rear sealing flange.
Use tool 999 2817. The sealing ring is to be
pressed in sufficiently so that a new wear surface
is obtained against the crankshaft. Then fit the se-
aling flange with a new seal against the engine.
Lubricate the seal’s rubber lip and the opposite
surface on the crankshaft before fitting. Great care
must be exercised so that the rubber lip is not
damaged by the edge of the crankshaft or turned
inside-out so that the spring jumps out of position.
Cut off protruding parts on the seal.
105. Protect the inside of the flywheel with Tectyl or
similar fluid and refit the flywheel. The tightening
torque is 70 Nm (7 kpm) (51.6 lbf. ft.). Fit the bear-
ing for the ingoing shaft with tool 999 1426 and
then refit the washer and the lock ring for the
bearing.
