REMOVAL PROCEDURE - BELT TENSIONER

No.	Procedure	Instructions
1	Removing air cleaner assembly.	Undo the hose clamp on the throttle body. Remove connector from mass air flow meter. Unclip electrical lead on throttle body.
2	Removing air cleaner assembly.	Unclip oil filler neck. Undo hexagon-head bolt M6 x 20 and remove entire air cleaner assembly.
3	Loosening belt pulley	Undo three hexagon-head bolts (M8 x 12) by approx. one half turn.
3		Note The belt pulley can also be loosened with a restraining strap after removal of the drive belt.
4	Removing drive belt	Mark belt travel direction with a coloured pen. Slacken belt, turning the tensioning pulley (wrench size 24 mm) clockwise, hold still and simultaneously take the belt off the drive pulleys.
5	Loosening three-phase generator	Undo right-hand fastening screws (in direction of travel) and unscrew.
5		Undo left-hand fastening screw (with deflection roller) by three turns. A gentle tap on the fastening screw loosens the threaded bushing in the generator arm (use aluminium mandrel).
6	Loosening air conditioning compressor	Undo front compressor fastening screws (2 ea.) and disconnect electrical plug connection.
		Lift generator up and out of the slotted generator bracket. Unscrew fastening screw and remove with deflection roller.
		Note Do not disconnect electrical connections or plug connection.
7	Loosening air conditioning compressor	Undo compressor fastening screw between the intake pipes of cylinders 4 and 5.
8	Removing throttle body	Disengage accelerator cable and remove throttle body. Pull off vacuum check valve.
9	Removing supply tank of the power steering system	Suck fluid out of the upper supply tank until the level is below the joint. Turn bayonet lock ring counter-clockwise.
10	Removing supply tank	Detach bracket from supply tank and B+ disconnection point and set aside. Pull supply tank up and off. Suck off fluid level of the lower supply tank and then immediately close the opening with a suitable plug ( "PHI" 30).
11	Detaching steering return line	In order to detach the line from the supply tank, push the red unlocking ring forward (arrows) and simultaneously pull out the line. Use two plastic spatulas to press the unlocking ring.
12	Detaching steering return line from the supply tank with tool	The line can also be detached using a commercially available tool. The removal tool from Messrs. Snap-on, for example, is recommendable. Insert tool between line and the red unlocking ring and unlock. Pull line to the rear and simultaneously press the tool against the red ring. Carefully protect the line against dirt and scratches with a cap.
13	Detaching hydraulic pump and steering supply line	Undo steering supply line (wrench size 17); simultaneously counter at the body (wrench size 27). Undo three hexagon-head bolts (M8 x 12) and remove hydraulic pump to the rear.
		Note If coolant hoses come into contact with Pentosin, clean them thoroughly without delay.
	Removing bracket with tensioning element	Undo flange for oil filler neck at the left rear bracket fastening screw. Immediately seal bore on the crankcase. Undo four hexagon-head bolts and remove bracket with tensioning element.
