Cleaning the crankcase
– Remove all screw plugs from the oil-
ways and, after cleaning the crankcase
by immersion in a cleaning bath or with
high-pressure cleaning equipment, blow
it dry with compressed air; flush out all
oilways particularly thoroughly and blow
through them, so that no particles of dirt
or swarf remain.
– After this, insert all screw plugs again
and check that the aluminium or sheet-
metal plugs for the oilways are firmly
seated. In case of doubt, renew them;
apply sealant E to all plugs before inser-
ting. To ensure firm location, secure the
aluminium plugs with light punch-marks
at the edge of the hole in the housing.
Oil spray jets
– First check for firm location and accura-
te spray direction; if necessary, re-align
the spray jet with light hammer-blows or
bend it carefully by hand until the cor-
rect position is reached. Check this with
the gauge - 41 -or work from the dra-
wing shown here (Fig. 171).
If oil spray jets have broken off or are loo-
se, new ones must be inserted. Proceed
as follows:
– Remove pieces of the old jet from the
drillway (with a suitable drift or similar
tool); degrease the entire area tho-
roughly; insert the new spray jet and
drive it in initially app. 6 - 8 mm farther
than its final position. Strike the projec-
ting end lightly with a hammer to bend it
slightly and ensure a firm seating in the
bore (Fig. 172).
