Injection system pipes and fuel injection pumps
1. Bracket; 2. Tube; 3. Flange; 4. Key; 5. Bracket
Attention! To perform the procedure, you will need an indicator with a division value of 0.001 mm with a special extension MD998384.
Installation
1. Set the piston of the 1st cylinder to TDC of the compression stroke.
2. Loosen the injection tube fittings on the pump.
3. Loosen the bolts and nuts securing the pump to the engine.
4. Check the protrusion of the indicator extension rod, which should be 10 mm, adjust if necessary by turning the nut.
5. Remove the plug from the pump head and screw in the MD998384 tool.
6. Carefully turn the crankshaft counterclockwise, 30° before TDC. The mark (notch) should be facing approximately 11 o'clock.
7. Set the indicator scale to 0 and turn the crankshaft slightly in both directions – the indicator arrow should remain stationary. Otherwise, repeat the crankshaft setting by 30° before TDC, ensuring that the arrow remains motionless.
8. Turn the crankshaft clockwise, aligning the mark with the 5° after TDC division – in this position of the crankshaft, the indicator reading should be 0.997–1.003 mm.
9. If the indicator reading differs from the specified one, then move the pump body to set the required indicator readings, then tighten the nuts and bolts securing the pump.
10. Repeat the installation procedure and check the injection timing several times - each time the crankshaft is set to 30° BTDC and 5° ATDC, the indicator reading should be 0.997–1.003 mm.
11. Replace the copper gasket and tighten the plug to 8 Nm.
12. Tighten the bolts and bleed the air.
