Diesel timing belt alignment marks
1. Tensioner; 2. Bolt; 3, 7. Vibration damper roller sprocket; 4. Tensioner B; 5. Belt; 6. Belt B; 8, 9. Tags
1. Disconnect the battery from ground.
2. Remove the drive belts, unscrew the bolts and remove the coolant pump and crankshaft pulleys.
3. Remove the top cover, paying attention to the location of the bolts.
4. Set the piston of the 1st cylinder to TDC of the compression stroke. From this point on, rotation of the crankshaft is not allowed.
5. Remove the crankshaft pulley.
6. Remove the lower belt cover.
7. Loosen the tensioner, move it towards the cooling pump, tighten the bolts.
8. Remove the camshaft and fuel pump sprockets, preventing the shafts of these units from rotating.
9. Remove the timing belt.
10. If the vibration damper belt is removed, secure the rollers by removing the plug on the right side and inserting a rod (8mm diameter screwdriver). On the left side, remove the cover and insert a thick rod (wrench extension).
11. Mark and remove the roller sprockets.
12. Check the condition of the belts; replace them if any defects are found.
Installation
1. Install the vibration damper shaft sprocket on the crankshaft, put on the pulley and tighten the bolt to a torque of 70 Nm.
2. Install the fuel pump sprocket, bushings (cone inward) and roller sprockets. Tighten the sprocket bolts to 38 Nm (1 - tension side; 2 – cooling pump).

3. Align the marks on the roller sprockets (1 – marks; 2 – tension side; 3 – belt B; 4 – tensioner B). Check the tension of the roller belt at location A.
4. Fit the belt (B) so that there is slack on the side where the tensioner rests.
5. Check the alignment of the marks by pressing on the belt with your finger. Without releasing the tension, loosen the tensioner bolt and nut. Tighten the nut first, then the bolt.
6. Check the tension of the roller belt (deflection 5–7 mm).
7. Check the alignment of the sprocket marks on the camshaft and pump belts and put the belt on, stretching it between the crankshaft and the pump (during installation, an assistant holds the pump sprocket).
8. Loosen the tensioner bolts and take up the slack in the belt. Tighten the bolt in the tensioner groove, then the axle bolt. Check the fit of the belt to the camshaft sprocket (2), the belt may be loose in the 10 o'clock sector. Make sure that the belt does not touch the adjacent parts (1 - pump sprocket).
9. Check the alignment of the sprocket marks, remove the belts and align the sprockets if necessary.
10. Turn the crankshaft so that the camshaft sprocket moves 2 teeth from the timing mark and return it back, setting the sprocket to its previous position.
11. Check the belt tension (the deflection should be no more than 4–5 mm).
12. Install the covers and other removed parts. Tighten the crankshaft pulley bolt to 64–73 N·m.
