Remove the front right mudguard. Remove the engine support bracket. Remove the poly V-belt tensioner roller. Remove the poly V-belt pulley from the crankshaft.
Caution! To avoid damaging the toothed ring, screw in the crankshaft poly V-belt pulley mounting screw only with the "T10368" mandrel.
Screw back the crankshaft poly V-belt pulley mounting screw using the T10368 mandrel.
Warning! Risk of engine damage. Do not turn the crankshaft from the TDC position with the pulley removed, as this may change the valve timing.
Release the "arrow" retainer of the wiring harness. Unscrew the "1" screw. Release the dipstick guide tube from the mount on the upper timing chain cover "arrow". Remove the dipstick guide tube from the upper timing chain cover.
Casing with 8 screws
Unscrew screws -1...8-.
Casing with 15 screws
Unscrew screws -1...15-.

Using a sharp flat spatula, cut the sealant in accessible places around the lower timing chain cover. Using a spatula, carefully release the lower timing chain cover in several stages so as not to deform it.
Installation
Note: Silicone sealant. Pay attention to the expiration date of the silicone sealant. The lower timing chain cover must be installed within 5 minutes after applying the silicone sealant. Replace the bolts and screws that are tightened by turning to the specified angle. Replace the O-rings, gaskets and self-locking nuts. Remove any remaining sealant from the mating surfaces on the cylinder block, upper part of the oil pan and on the lower timing chain cover with a chemical solvent for sealants. Degrease the mating surfaces. Check that both pins "arrows" for centering the lower timing chain cover are present.
Cut off the tip of the tube of sealant at the front mark (hole diameter about 3mm). Apply silicone sealant to the clean mating surfaces of the lower timing chain cover -arrow 1- and to the surfaces -arrow 2-, as shown in the figure.
Casing with 8 screws
- Thickness of sealant bead: 2...3 mm.
Casing with 15 screws
- Thickness of sealant strip: 2...3 mm.
Note: The lower timing chain cover must be installed within 5 minutes of applying the silicone sealant. The sealant bead must not be wider than specified, otherwise excess sealant will enter the oil pan and clog the mesh filter in the oil pickup tube.
Tightening order of the lower timing chain cover with 8 screws
Tighten screws -1 through 8- in 2 stages in the sequence shown.
1. Tighten the screws to a torque of 8 Nm.
2. 45° (tighten by 1/8 turn.).
Tightening order of the lower timing chain cover with 15 screws
Tighten screws -1 through 15- in 2 stages in the sequence shown.
1. Tighten the screws to a torque of 8 Nm.
2. 45° (tighten by 1/8 turn.).
Note: After installing the lower timing chain cover, allow the sealant to dry for approximately 30 minutes. Only then can you add engine oil.
Installation in reverse order. Install the poly V-belt tensioner roller. Adjust the power unit supports. Fill with engine oil.
