TA6300 AMT KIT 8 7 MECHATRONIC GEAR ACTUATOR UNIT (MGA) REMOVAL AND RE-FITMENT ON 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.
