Note: When disassembling, mark the removed parts that are suitable for further use so that when reassembling, you can install them in their original places and positions.
Remove the intake manifold and exhaust manifold.
Remove the coolant pump.
Remove the oil pan, then the crankshaft pulley and the camshaft timing belt protective covers.
Loosen the timing belt tension roller axle mounting nut and remove the belt.
Remove the cylinder head.
Loosen the bolts securing the clutch housing to the flywheel and remove the housing together with the pressure plate. This will release the driven clutch disk.

The arrows show the marks for orientation in the cylinder of the connecting rods and pistons, which should be directed towards the camshaft drive
Loosen the connecting rod bolt nuts and remove the connecting rod caps.
Remove the pistons with connecting rods through the cylinders.
Remove the connecting rod bearing shells and determine the degree of wear of the shells. If the shells can be reused, mark the shells to determine their position ("top", "bottom") and mark the corresponding connecting rods.
Unclamp and remove the piston pin retaining rings using round-nose pliers and press out the pins using a mandrel.
Check the axial free play of the crankshaft.
Loosen the main bearing cap mounting bolts and remove the caps together with the lower bearing shells.
Remove the crankshaft from the bearing seats, and then the upper bearing shells.
The main bearing caps are marked with numbers 1-5, indicating the order in which they were installed during engine assembly. If the main bearing shells are to be reused, both the lower and upper shells must be marked in the same way.
