3. Set dial gauge with magnetic base on the injector rocker roller and pre-load by 6 mm.
4. Turn crankshaft clockwise until dial gauge pointer reaches the minimum value.
5. Reset the dial gauge.
6. Turn flywheel anticlockwise until dial gauge reads cam lift 4.90 ± 0.05 mm.
7. If conditions not met, loosen camshaft gear screws, use slots and repeat the check.
8. Tighten the screws to the required torque.

⚠ Follow the sequence specified in the table and check position using pin 99360612

Tools: Polygonal wrench, Thickness gauge, Dynamometric wrench, Pin 99360612

1. Bring the cylinder to be adjusted to the firing (bursting) phase; symmetric pairs are 1-6, 2-5, 3-4.
2. Slacken the locking nut of the rocker arm adjusting screw.
3. Insert the thickness gauge blade and adjust the screw so the blade slides with slight friction.
4. Tighten the adjustment screw to 5 Nm (0.5 kgm).
5. Untighten the adjustment screw by 1/2 to 3/4 rotation.
6. Tighten the locking nut while holding the adjustment screw.
7. For injection rockers, loosen the nut of the rocker adjustment screw controlling the pump injector.
8. Tighten the adjusting screw until the pumping element reaches end-of-stroke.

⚠ Components can be damaged very quickly in presence of water or impurity within the fuel

1. Place a container underneath the filter.
2. Slightly loosen the pump screw-valve to drain water.
3. Drain the water contained in the filter bottom.
4. Lock the screw as soon as fuel starts bleeding.

⚠ Do not operate immediately after engine disconnection; wait for cooling

⚠ Protect eyes and skin from high pressure jet of cooling liquid

1. Check pipes from engine to radiator and vice versa when engine disconnected and running.
2. Note any seepage and the state of pipes, especially near coupling clamps.
3. Verify the radiator is clean and the fan flywheels work correctly.
4. Check for leakage from connectors, manifold and radiating unit.
5. Check cooling liquid density every year before winter and replace every two years.

⚠ Motor oil reaches very high temperature; wear protection gloves

⚠ Do not mix oils with different features when topping up

1. Drain oil when engine is hot.
2. Place a container under the drain plug (3).
3. Unscrew the plug, remove the dipstick (1) and inserting plug (2) to ease oil outflow.
4. After complete drainage, screw the plug and carry out clean oil filling.
5. Pour the prescribed quantity and quality of oil through filler (2) of tappet cover.
6. Check the level through the dipstick until next to the maximum level notch.

⚠ The oil filter contains a quantity of oil of about 1 kg

Tools: 99360314

1. Drain oil as described in Engine oil change chapter.
2. Use tool 99360314 to remove the oil filter.

5. Bleed air from supply system.

⚠ Filter cartridge must not be prefilled to prevent circulating dirt damaging injector/pump components

1. Disconnect electric connector.
2. Unlock prefilter and change it.
3. Before refitting a new cartridge, wet the seal with fuel oil or engine oil.
4. Lock cartridge by hand until in contact with support, then lock by 3/4 of a rev. at predefined tightening torque.
5. Bleed air from fuel filter.

⚠ Belt tensioner is automatic and requires no adjustment

Tools: Belt tensioner tool

1. Operate using a specific tool on the belt tensioner in the direction shown by the arrow to remove the belt.
