to
6
are accessible.
Work step 1 for loosening bolts connecting
electric drive motor
V141
to sealing flange
Note
Arrow A
points to the wire of the

Bolts
1
to
3
are only accessible in the position as indicated by
arrow A
and
arrow B
.
Unscrew bolts
1
to
3
from engine, but leave them inserted in
electric drive motor

Work step 2 for loosening bolts connecting
electric drive motor
V141
to sealing flange
Note
Arrow A
points to the wire of the
drive motor temperature sender

Turn
electric drive motor
V141
in such a way that the two markings
arrow A
and
arrow B
are aligned as shown in illustration.
Unscrew bolts

Caution
Risk of damage to components.
The
electric drive motor
V141
is permanently attached to the intermediate plate which must thus not be damaged.
The
electric drive motor
V141
is pulled off engine and removed together with the intermediate plate.
Both mechanics must hold the assembly only on the
electric drive motor
V141
and not on the intermediate plate.
If not yet fitted, screw
guide pins
T10515
into engine as shown in illustration.
Note
A second mechanic is required for the next work steps.
Both mechanics must pull the
electric drive motor
V141
towards front out of the centring elements, without canting the assembly on the guide pins.
Caution
Risk of damage to components.
Place
electric drive motor
V141
on a clean surface with intermediate plate facing upwards.
Seal all open fluid passages on
electric drive motor
V141
and on engine with sealing plugs
