Removing bracket for generator
Removal
CAUTION: Risk of short circuit with battery connected.
- The battery must be disconnected before any work is carried out on the engine.
1. Drain coolant. Open cap of coolant expansion tank. Unscrew coolant drain plugs on left and right and drain the coolant. After draining the coolant, fit new sealing rings on the drain plugs.
Drain plug tightening torque: 10 to 15 Nm (7.5 to 11 ftlb.)
2. Remove air cleaner housing. Undo hexagon-head bolt M6 x 34. Undo the hose clamp on the throttle body. Remove connector from hot film mass air flow meter.
3. Removing drive belt.
4. Unclip the cable from the hot film air flow meter on the expansion tank of the hydraulic pump and lay it aside. Detach the holder from the oil filler neck.
5. Undo fastening screws on the expansion tank -upper arrows- (two M8 screws) and the four screws -lower arrows- (three M8 screws and one M6 screw) on the hydraulic pump. Pull the expansion tank with hydraulic lines and with connected lines up out of the fastening bracket and lay aside to the right-hand side.
6. Remove holder for oil filter bracket. Unscrew the M6 screw and undo the M8 screw for this purpose. Lift the holder out.
7. Separate the B+ disconnection point -arrow- under the cover for this purpose. Unscrew the left fastening screw. Unscrew the right fastening screw by approx. 1 cm. Then drive it in with gentle taps of a hammer until the screw head makes contact with the generator again. Now unscrew fastening screw completely. Lift the generator upwards out of the engine compartment.
8. Remove air conditioning compressor from the bracket for the generator. Unscrew the three screws -arrows- for this purpose. The throttle body can be swung upward for better accessibility to the front screw. To do this, the two hose clamps must be removed.
NOTE: Do not open air conditioning system:
9. Remove the compressor. Disconnect the electrical connection on the compressor. Unplug compressor. Lift the compressor out of the engine compartment and lay it aside with the leads still connected. Protect the body from damage with a cover.
10. Unclip coolant hose. To do this, unclip the safety bracket on the coolant neck with a screwdriver and pull the coolant hose up and out.
11. Detach the coolant outlet neck of cylinder bank 4 to 6. Undo the two hexagon-head bolts on the coolant outlet neck for this purpose.
12. Detach bracket for generator. Unscrew the four fastening screws -arrows- on the bracket for the generator.
13. Pull off the hose clamp -arrow- on the coolant connecting hose. Take bracket for the generator out of the engine compartment upward and to the right.
14. Separate bracket for the generator. The bracket can be disassembled in the event of leaks. Unscrew the three screws -arrows- for this purpose. Pull the two parts apart. Make sure that the two dowel sleeves are not lost. Use a new O-ring with Vaseline when assembling the bracket for the generator.
Tightening torque of the three screws: 23 Nm (17 ftlb.)
Installing bracket for generator
1. Install bracket for the generator. Replace the four O-rings on the connecting sleeves between the two coolant outlet necks and the bracket for the generator. Insert the bracket into the coolant outlet neck of cylinder bank 1 to 3 from the right-hand side. Then screw in the four fastening screws.
Tightening torque: 65 Nm (48 ftlb.)
NOTE: Insert the front right screw -inset- with Loctite 574.
2. Push on the coolant connecting hose between the oil/coolant heat exchanger and the bracket again and tighten the hose clamp -arrow-.
3. Fit coolant outlet neck of cylinder bank 4 to 6. Insert the neck with the connecting sleeve into the bracket for the generator for this purpose. Tighten the two fastening screws on the coolant outlet neck.
Tightening torque: 10 Nm (7.5 ftlb.)
4. Insert retaining clip. Insert the retaining clip -arrow- into the groove provided as shown. Replace the O-ring on the coolant hose.
5. Push on coolant hose. Align the connection neck of the coolant hose as shown in the illustration. -lug/groove arrow- Press the coolant hose firmly against the connection neck. The clip must audibly engage. Pull the hose slightly to check for secure seating.
6. Fit air-conditioning compressor. To do this, move the compressor into installation position. Tighten the three fastening screws -arrows- of the air conditioning compressor.
Tightening torque: 23 Nm (17 ftlb.)
7. Install generator. Return the generator to its mounting position. Connect plug connection and connect the B+ line.
Tightening torque for M8 hexagon nut: 15 Nm (11 ftlb.)
Tightening torque for M10 hexagon-head bolt: 46 Nm (34 ftlb.)
8. Install holder for oil filter bracket. To do this, push in the holder in downward direction.
9. Install hydraulic pump. Return the hydraulic pump with connected lines to its installation position and tighten the fastening screws -arrows-.
Tightening torque for M8 fastening screws: 23 Nm (17 ftlb.)
Tightening torque for M6 fastening screw: 10 Nm (7.5 ftlb.)
Tightening torque for M8 fastening screw on the expansion tank: 23 Nm (17 ftlb.)
10. Refit oil filler neck and clip the cable from the hot film mass air flow meter into the holder on the hydraulic expansion tank.
11. Install drive belt.
12. Install air cleaner housing. Refit air cleaner housing into the mounts in the body. Tighten hexagon-head bolt. Tighten the hose clamp on the throttle body and push the plug onto the hot film mass air flow meter.
Tightening torque for hexagon-head bolt M6 x 34: 10 Nm (7.5 ftlb.)
13. Connect battery. Reconnect the battery ground cable.
14. Fill in coolant. Fill in coolant through the expansion tank. Carefully bleed the vehicle.
