Removing
CAUTION!
There is a risk of injury. The pressure in the R tronic hydraulic system may be up to 50 bar.
• Always reduce system pressure first before working on the R tronic hydraulic system => [ Hydraulic System, R Tronic, Building System Pressure ] Procedures.
• When installing, bring all cable ties back to same positions.
- Move the selector lever into "N".
- Remove the air ducts - 1 - and - 2 -.
- Remove the front noise insulation - 2 -.
- Remove the left and right rear wheel housing liners.
- Remove the rear bumper cover.
- Body Protectors, Installing. Refer to => [ Body Protectors, Installing ] Body Protectors, Installing.
- Remove the left - 1 - and right - 3 - engine compartment trim.
- Remove the engine cover - 2 -.
- Remove the air filter housing.
- Remove the bolts - 1 - and the heat shield - arrow -.
- Disconnect electrical connectors - 2 - and - 3 -.
• Disregard - 1 and 4 -.
CAUTION!
There is a risk of mixing up the electrical connectors.
• To prevent the electrical connectors on the gear selection valves from getting mixed up, they are identified by color. If the color marking is no longer visible, mark the electrical connectors before removal so they will not get mixed up.
Color identification:
- 1 -, "blue"
- 3 - , "white"
- 4 -, "green"
- Disconnect electrical connectors - 1 through 5 - on the sensor and on the valves.
- Remove bolts - 1 through 3 -.
- Remove bracket - A -.
• To collect escaping hydraulic oil, lay a clean cloth under the separating points.
- Loosen the hydraulic line threaded connection - 1 -.
- Remove the hydraulic line threaded connector - 2 -.
- Remove the hydraulic line threaded connection - 4 - to the clutch slave cylinder.
CAUTION!
There is a risk of destroying the hydraulic return line connection.
• Only remove the hydraulic return hose using the method described.
- Remove the hydraulic return hose - 3 - from the R tronic shift actuator. Refer to => [ Hydraulic Return Hose ] .
- Remove the bolts - arrows - and the R tronic shift actuator.
Install the shift actuator.
Tightening specifications:
• Refer to => [ Shift Actuator, R Tronic Assembly Overview ]
• Refer to => [ Hydraulic Unit, R Tronic Assembly Overview ] Hydraulic Unit, R Tronic Assembly Overview
• Refer to => [ Heat Shield Over the R tronic Shift Actuator,
Tightening Specifications ]
• Bracket for the R tronic shift actuator on the transmission. Refer to => [ Hydraulic Lines, R Tronic Assembly Overview ]
- Bring the selector rod in the R tronic shift actuator into the position shown.
• The shift finger - 2 - must be centered between the locking fork - 1 -.
- Bring the selector rods in the transmission into the position shown.
• The openings in the selector rod yokes - 1 through 4 - must align.
• When installing, bring all cable ties back to same positions.
CAUTION!
There is a risk of contaminating the hydraulic system.
• Cover open parts of the R tronic shift actuator and transmission.
- Remove the sealant residue on the R tronic shift actuator and transmission.
- Clean sealing surfaces; they must be free from oil or grease.
• Use Sealant (AMV 174 004 01).
• Pay attention the expiration date on the sealant.
- Cut off the tip of the sealant tube at the first marking (nozzle diameter approximately 1 mm).
- Make sure both alignment sleeves - 1 - are installed.
CAUTION!
There is a risk of plugging the hydraulic system with excess sealant.
• Do not apply the sealant bead thicker than what is specified.
- Apply the sealant bead - arrow - to the clean transmission sealing surface as shown in the illustration.
• Sealant bead thickness: 1.5 mm.
• Install the R tronic shift actuator within 5 minutes of applying the sealant.
- Insert bolts - 1 - and - 2 - with Sealant (AMV 174 004 01) and tighten by hand.
- Insert bolts - 3 through 8 - with sealant (AMV 174 004 01) and tighten by hand.
- Tighten the bolts to the specification in the sequence - 1 through 8 -.
Further installation is in reverse order, paying attention to the following:
- Check the oil level in the R tronic hydraulic unit and fill. Refer to => [ Oil Level in R Tronic Hydraulic Unit ] Description and Operation.
- Install the rear bumper cover.
- Install the rear wheel housing liners and front noise insulation.
- Install the air filter housing.
- Install the engine compartment trim.
- Perform gear selector basic setting. Refer to => [ Gear Selector Basic Setting ] Testing and Inspection.
