Engine Assembly

Install the main bearing shells in the bed of the block, lubricate with engine oil and lay the crankshaft in the bearings. The axial movement of the crankshaft is selected on the third support, the bearing shells of which have two thrust collars.

Pick up the main bearing caps with liners and install them on the bed of the block, tighten the bolts of their fastening to a torque of 6.5 kgf·m.

Install three piston rings into the corresponding grooves in the pistons, placing their locks through 120°.

Orient the piston ring locks forward or backward in the direction of the vehicle. There is a mark on the lower compression and oil scraper rings «top» or «oben» («top»), which must face upwards when the ring is installed in the groove.

Install the pistons, orienting the arrow pressed out on the bottom of the piston, forward in the direction of the car (towards the camshaft drive).

Lubricate pistons and piston rings with engine oil, compress the piston rings in the grooves with a suitable mounting sleeve and insert the pistons with connecting rods into the cylinders.

Install the liners in the connecting rods and connecting rod caps in accordance with the marks made during disassembly, if worn liners are used.

Install the connecting rods and covers on the crankshaft journals, while the sagging on the covers should be directed towards the camshaft drive.

Lightly tighten the nuts of the connecting rod bolts, then finally tighten them to a torque of 3.0 kgf·m and tighten them by 90°.


Install the rear oil seal holder with a new cardboard gasket. Using tool 2003/1, press the oil seal into the holder.

Install flywheel.

Install a new cylinder head cover gasket. Install the oil pump cover so that the pinion lugs engage with the flats on the crankshaft.

Install the oil pickup tube.

Install the oil pan with a new gasket.

Install water pump, thermostat and thermostat housing.
