Recommended fixtures:
1 - clamp for crankshaft 0194-A;
2 - pin for blocking the camshaft 0194-B;
3 - fixation from rotation of the flywheel 0194-C;
4 - calibration pin of the high pressure fuel pump pulley 0194-A.
Remove:
- front right wheel;
- front right fender liner;
- accessory drive belt (see corresponding operation).
Insert tool 3 into the hole located on the bed block of the crankshaft main journals (1).
Remove the implement drive pulley.
Move the electrical harness away from the upper timing case.
Remove the lower and upper timing cover.
Remove the engine speed sensor (2).
Note. magnetic track «A» must not show any signs of damage and should not be approached by magnetized objects, otherwise the crankshaft pulley must be replaced.
Remove the bolt (3) corner bracket to prevent displacement. Install the attachment drive pulley bolt.
Remove tool 3.
Rotate the crankshaft at the attachment drive bolt clockwise.
Set the camshaft to the control point using tool 2.
Lock the crankshaft pulley with tool 1 with the pin.
Set the injection pump pulley to the reference point using tool 4.
Remove:
- engine mount assembly (5) and locking bracket of the travel limiter (6);
- right intermediate engine mount (4).
Loosen the mounting bolt (7) tensioner pulley by holding it in the taut position with a hex wrench.
Remove the timing belt.
Installation
Note. The pistons should be at half stroke when adjusted at the reference point.
Attention. The pin must be at the top (vertical position): 90°to the position at the checkpoint to close the intake and exhaust valves in cylinder no. 1.
Check the tightness of the sealing sleeves at the level of the oil pump and camshaft. Make sure that the rollers and the coolant pump rotate freely without gaps or burrs.
Also check that the rollers are not making noise and/or splattering grease.
Also check the condition of the surface of these rollers.
Install and tighten well in the following order:
1. Timing pulley.
2. Guide roller.
3. Camshaft pulley (making sure that the belt is firmly pressed against the roller).
4. High pressure pump.
5. Pump of the cooling system.
6. Tension roller.
Note. Make sure the back of the belt is tight against the idler pulley and that the belt leg between the crankshaft pulley and the camshaft pulley has only 33 teeth free.
Remove the bolt (7) tension roller.
Use the hex wrench to move the pointer (8) tension roller to the middle of the control zone «b». turning the tensioner counterclockwise.
tighten bolt (7) tension roller.
Remove tools 1 and 2. Check that the timing pulley is firmly pressed against the crankshaft, turn the crankshaft 10 revolutions.
Install tools 1 and 2.
Make sure the index is in the correct location (8) on the dynamic tensioner, otherwise repeat the timing belt installation procedure.
Remove tools 1 and 2.
Install in place:
- bracket of the mechanism that prevents the engine from stopping (3);
- speed sensor (2);
- right intermediate engine mount (4);
- engine mount assembly (5) and locking bracket of the travel limiter (6);
- lower casing of the gas distribution mechanism;
- fixture 3 on the flywheel;
- attachment drive pulley;
- then angle tighten 180°.
Remove tool 3.
Install the accessory drive belt.
Proceed in reverse order to removal.
