Attention! Before removing the pistons and connecting rods, remove the cylinder head, oil pan and oil pump.
1. Remove the shoulder at the top of the cylinder (photo).
11.1 Removing the shoulder in the cylinder using a reamer
2. Turn the engine over and check the end play of the connecting rods (photo), inserting feeler gauges between crankshaft and connecting rod. The axial play will be equal to the total thickness of the probes at which the play disappears. If the end play of the connecting rod exceeds the standard value, then the connecting rod should be replaced. If new connecting rods are installed (or co-lenval), then the axial play may be less than normal (in this case it is necessary to grind the connecting rods, if necessary, consult a car service workshop). Repeat the procedure for the rest of the connecting rods.
11.2 Checking the end play of the connecting rod
3. If there are no marks on the connecting rods and connecting rod caps, mark them with the number of the corresponding cylinder (photo).
11.3 Marking the connecting rod with the cylinder number
4. Loosen the cap nuts by loosening them 1/2 turn at a time until the nuts can be unscrewed by hand. Remove the cover from the connecting rod of the first cylinder together with the liner, do not remove the liner from the cover. Push the piston with the connecting rod and the liner through the top of the cylinder, after putting the hose pieces on the bolts (photo).

5. Repeat the procedure for all other cylinders.
6. Assemble connecting rods with caps, hand-tighten cap nuts.
