Workshop Manual S3.8 Engine A030K288 (Issue 2) 01-2010 pump away from the engine slowly when the flow of fuel decreases. Fig. 10 and ultimately the flow nearly stops, giving a drop in 15 to 20 seconds. Fig. 11. Check flywheel position once again to make sure that the yellow mark (18 before TDC) on the flywheel aligns with the pointer. 9. Tighten fuel injection pump bolts (4 numbers) carefully so as not to disturb the position of the fuel injection pump. 10.Turn crankshaft in the reverse direction by approx. 30 degrees. The fuel will start flowing freely. Then slowly turn crankshaft in the forward direction till the fuel flow nearly stops and a drop forms on the swan neck in 15 to 20 seconds.
Fig. 10 Fig. 11 The position should coincide with 20 degrees before TDC mark on flywheel aligning with the pointer. Fig. 12. This check confirms that the fuel injection timing has been correctly set. 11. Disconnect swan neck and fit back delivery valve, spring and peg after cleaning them. Fig. 13. Tighten delivery valve holder to 4.5 mkg. Fit delivery valve holder clamps. 12.Refit timing gear housing plug and clutch housing inspection cover. 13.Disconnect diesel bowl from the fuel injection pump gallery. 14. Connect fuel hoses to the feed pump and fuel injection pump main gallery. 15.Connect high pressure lines to injection pumps. Tighten cap nuts to 2.5 mkg.
Ensure that the high pressure lines are free from tension. If necessary, align high pressure lines with special tools, Part No 312 580 0085. Fig. 12 16.Bleed the fuel system as follows. Unscrew and operate hand primer (up and down strokes) until resistance is felt. Loosen the bleeding screw on the fuel filter and allow air to escape. Operate the primer slowly with the bleeding screw open till bubble free fuel starts flowing. Tighten the bleeding screw. Bleed the fuel injection pump gallery in the same manner and tighten bleeding screw. Operate the hand primer for a few strokes. Check for Fig. 13 32
