AMT KIT 26 G. POWER UNIT (PWU) BASE PLATE REMOVAL AND RE-FITMENT ON BENCH: - Removal: Disconnect all the connectors of the system wiring harness (DC Motor, Cultch Position Sensor and Transmission Control Unit) and remove the ‘Plastic Clip’ pulling it out from its threaded hole on the ‘Power Unit Base Plate’ body. Remove the ‘Mechatronic Gear Actuator’ unit (MGA) first (refer the procedure. Mechatronic Gear Actuator Unit (MGA) Removal and ReFitment on Bench). Installation: Assemble the ‘Power Unit Base Plate’ on the fixture. 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 ‘Mechatronic Gear Actuator’ fixing screws. Assemble the O-rings on the connectors. Mount the connectors with O-rings in their seats on ‘Power Unit Base Plate’, after lubrication with new ‘CS Speed’ oil also lubricate the ‘Mechatronic Gear Actuator’ seats. Remove traces of oil from the ‘Mechatronic Gear Actuator’ seal surface in contact with gasket with care to avoid contamination from foreign materials (dust, metal burrs, etc.) or surface damages. Assemble the gasket on the ‘Mechatronic Gear Actuator’ with the correct orientation, inserting the centering pins into the fixing holes of the ‘Mechatronic Gear Actuator’ body. Position the ‘Mechatronic Gear Actuator’ with gasket over the ‘Power Unit Base Plate’ using the threaded rods for reference and moving it parallel towards the mating surface. When the ‘Mechatronic Gear Actuator’ body seats came in contact with O-rings, push it slowly, with appropriate load to complete the assembly. Unscrew the rods and screw the three screws for fixing the ‘Mechatronic Gear Actuator’ on ‘Power Unit Base Plate’ at the right torque 10 ± 1 Nm. Connect the connectors of the wiring harness on the ‘Transmission Control Unit’ and ‘Cultch Position Sensor’. Insert the plastic clip into its threaded hole on the ‘Power Unit Base Plate’ body and connect the connector of wiring harness on the DC Motor. Fill the ‘Oil Tank’ with new ‘CS Speed’ oil, at the Max. Level “@ 0 bar” (no pressure in the hydraulic circuit) and restore it after the purge procedure. Screw the ‘Oil Tank Cap’ at the right torque.
