BENCH:-
Removal:
CAUTION
Ensure there is “NO PRESSURE” in the hydraulic
circuit.
Disconnect the connector of the wiring harness
from the ‘Transmission Control Unit’.
Drain the hydraulic oil from the “Oil Tank”, by first
unscrewing the “Oil Tank Cap” and then remove
hydraulic system and drain oil in to canister.
Unscrew and remove the three screws fixing
“Mechatronic Gear Actuator” on “Power Unit Base
Plate”.
Remove the “Mechatronic Gear Actuator” by
pulling its body by hand in vertical direction; pay
attention that a small quantity of oil will flow out
from the tank port.
Remove the oil port’s connectors with O-rings and
the flat gasket. In the pictures below is an
example of dismounting, where the gasket and
one O-ring remain in the “Mechatronic Gear
Actuator” seat and the other parts remain in the
“Power Unit Base Plate” Seats.
Installation:
NOTE
Verify that the gearbox is in neutral gear position,
because the “Mechatronic Gear Actuator” spare
part is provided in this position; otherwise rotate
the gearbox command lever by hand to achieve
the position corresponding to the spare part
before mounting.
In order to guarantee right “Mechatronic Gear
Actuator” translation during the mounting, to avoid
O-rings damages, screw three rods φ6x100 mm
length, with 15 mm threaded M6, in the “Power
Unit Base Plate” holes used by right “Mechatronic
Gear Actuator” fixing screws and shown in the
picture below.
Remove traces of oil from the “Power Unit Base
Plate” seal surface in contact with the spare
gasket, with care to avoid contamination from
foreign materials (dust, metal burrs, etc.) or
surface damages.
Assemble the spare parts O-rings on the spare
parts connectors (see the detail on below picture).
Mount the spare parts connectors with O-rings in
their “Power Unit Base Plate” seats (see picture
below), after lubrication with new ‘CS Speed’ oil.
