Install the connecting rod cap by placing a piece of PG I type plastic gauge wire between the unlubricated bearing and the connecting rod washer.
Tighten the connecting rod cap bolt nuts. Remove the cover and, using the scale printed on the package, determine the size of the gap by the flattening of the wire.
Pull the pistons with connecting rods through the cylinders.
Insert the piston rings into the cylinders and check the piston ring gap with a feeler gauge. Check the gap between the piston rings and grooves with a set of feeler gauges, inserting the ring into the corresponding groove, observing their orientation (see picture). If the ring is labeled TOR («Top»), then install the ring with the mark up (to the bottom of the piston).
Lubricate the grooves on the piston and the piston rings with engine oil and install the rings on the piston, placing the ring locks at 180°.
Compress the piston rings with a mandrel and insert the pistons with connecting rods into the cylinders, after lubricating their walls with engine oil (point the arrows on the bottom of the pistons towards the camshaft drive).
Lubricate the connecting rod bearing shells to the connecting rod journals with engine oil. Install the connecting rod caps on the crankshaft journals and tighten the connecting rod bolts.
Install the oil pump.
Install the oil pan.
