5 Turn the crankshaft 30° clockwise
from the top dead cen-
tre of cylinder no. Al (in this position the crank pin of cylinder
1 points straight upwards).
6 Re-install the end cover with help of the guiding pins.
Check that the hose seal against the underneath surface of the
end cover comes to its place properly and that the under edge
of the pump cover comes 0.15 ... 0.55 mm above the under edge
of the engine block. Do not forget to fasten the end cover also
from the inside of the block (4 screws).
7 Re-install the water pumps. Provided the assembly has
been carried out correctly the counterweights now point down-
wards and the crank pin of cyl. 1 straight upwards, see Fig
11-7.
11.4.3 Checking
1 Turn the crankshaft 45° clockwise (from the position
when the crank pin of cylinder 1 points straight upwards). The
counterweights rotate with a speed twice the speed of the
crankshaft. This means that the counterweight on bank A
should point straight to the side. The scribing mark on the
counterweight is now visible through the hole (14) provided the
assembly is correct, see Fig 11-6 View C and Fig 11-7.
2 Turn the crankshaft further 90° clockwise. The scribing
mark of the counterweight on bank B should now be visible
through the hole (14), otherwise the assembly is to be repeated.
3 Check the backlash of the gear wheel (12) and the
backlash of the water pump gear wheel through the holes in
the cover (see section 06.2 pos. 19 and 23 b).
4 Re-install the lube oil pump, pipes and before start check
that the bearings get lube oil.
Note! When dismantling a water pump(s) it will affect the counter-
balance system as it gets its driving force via the gear wheels
of the water pumps.It is most convenient to turn the crankshaft
30° clockwise from the top dead centre of cylinder 1 (to the
position when crank pin no. 1 points straight upwards and the
counterweights point straight downwards). In this position the
water pump(s) can be removed and installed without affection
to the counterbalance system.
