Bracket For Generator
Removing and installing bracket for generator - GT3
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. Open coolant drain plugs on left and right and drain the coolant. After draining the coolant, fit new sealing rings on the drain plugs.
Tightening torque: 10 to 15 Nm (7.5 to 11 ftlb.)
(the illustration shows only one drain plug)
2. Remove air cleaner housing.
Undo hexagon-head bolt M6 x 34. Undo the hose clamps on the throttle body. Remove connector from mass air flow meter.
3. Remove drive belt.
4. Unclip the cable from the air flow sensor on the reservoir of the hydraulic pump and lay it aside. Detach oil filler neck from the holder.
5. Undo fastening screws on the reservoir (two M8 screws) and four screws (three MS screws and one M6 screw) on the hydraulic pump. Pull the expansion tank with hydraulic pump and 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. Remove generator.
Separate the B+ disconnection point under the cover for this purpose.
Unscrew the left fastening screw. Undo right fastening screw by approx. three turns.
Loosen the threaded bushing in the alternator swivel arm with a light tap on the screw head.
Then unscrew the fastening screw. Lift the generator out.
8. Remove compressor from the bracket for the generator. Unscrew the three screws for this purpose. The throttle body can be swung upward for better accessibility to the front screw. To do this, the two inner hose clamps must be removed.
9. Remove the compressor. Disconnect the electrical connection on the 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.
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 - 6. Undo the two hexagon-head bolts on the coolant outlet neck for this purpose.
12. Detach bracket for generator.
Unscrew the four bracket fastening screws.
13. Loosen the hose clamp on the coolant connecting hose and pull the hose off. 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 leakage. Unscrew the three screws for this purpose. Pull the two parts apart. Make sure that the two dowel sleeves are not lost. Use a new O-ring when assembling the bracket for the generator.
Tightening torque of the three screws: 23 Nm (17 ftlb.)
Installation:
1. Install bracket for the generator.
Replace the four O-rings on the two 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 1-3 from the right-hand side. Then screw in the four fastening screws.
Important: The front right screw must be inserted with Loctite 574 (as shown in the illustration).
2. Tighten the four fastening screws to 65 Nm (48 ftlb.).
3. Push on the coolant connecting hose between the oil/coolant heat exchanger and the bracket again and tighten the hose clamp.
4. Fit coolant outlet neck of cylinder bank 4 - 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 9.7 Nm (7.0 ftlb.)
5. Insert retaining clip.
Insert the retaining clip into the groove provided as shown. Replace the 0-ring on the coolant hose.
6. Push on coolant hose.
Align the connection neck of the coolant hose as shown in the illustration (lug/groove). Press the coolant hose firmly against the connection neck. The clip must audibly engage.
7. Fit compressor.
Coat the spacer sleeve of the rear fastening screw with grease to keep it from falling out. Lift the compressor back into its installation position and push on the electrical connection.
8. Fasten the compressor.
Tighten the three compressor fastening screws to 23 Nm (17 ftlb.).
If the throttle body has been turned it must be returned to installation position.
9. Install generator.
Return the generator to its mounting position. Reconnect the plug connections and screw on the B+ lead.
Tightening torques:
Hexagon nut, M16 x 1.5, 65 Nm (48 ftlb.)
Hexagon-head bolt, M10, 46 Nm (34 ftlb.)
Hexagon nut, M8, 15 Nm (11 ftlb.)
Deflection roller, M10, 46 Nm (34 ftlb.)
10. Install holder for oil filter bracket.
To do this, push in the holder in downward direction.
Tighten the M6 screw to 10 Nm (7.5 ftlb.) and the M8 screw to 23 Nm (17 ftlb.).
11. Install hydraulic pump.
Return the hydraulic pump with connected lines to its installation position.
Tighten the four fastening screws. Tighten the three M8 screws to 23 Nm (17 ftlb.) and the M6 screw to 10 Nm (7.5 ftlb.).
Tighten the two fastening screws on the reservoir to 23 Nm (17 ftlb.).
12. Insert oil filler neck in its holder again. Clip the cable from the air flow sensor into the holder on the hydraulic expansion tank again.
13. Install drive belt.
14. Install air cleaner housing.
Insert air cleaner housing in its holder again.
Tighten the M6 x 34 hexagon-head bolt to 9.7 Nm (7.0 ftlb.).
Tighten the hose clamp on the throttle body and push the plug onto the hot film mass air flow sensor.
15. Connect battery.
Reconnect the battery ground cable.
16. Fill in coolant.
Fill in coolant through the coolant expansion tank. Carefully bleed the vehicle.
