2. Inspect the bottom ends of the connecting rods to make sure the connecting rod caps and the connecting rods themselves are marked according to their position. If necessary, mark them yourself with a file or center punch.
3. Turn the crankshaft so that the two pistons are in the TDC. and two - in n.m.t., and unscrew the nuts of the connecting rod caps. Do this in sequence, starting with the first cover and removing it along with the connecting rod bearing shell. It may be necessary to pry off the cover to remove it, but be careful not to damage the cover and insert as this may cause damage. they may be suitable for further use. If you are going to use cylinder liners, you can remove the liner together with the connecting rod and piston, first removing the strips fixing it and swinging the liner to make it easier to remove. If you are not going to change the sleeves, you should push the piston with the connecting rod out of the sleeve with a hammer handle. Temporarily install the connecting rod cap with the bearing shell on the connecting rod and fix it with nuts (at the same time, you should check if the upper liner is left on the crankshaft - it must be removed and installed in the cover so that it is not lost.
4. Repeat the indicated operations on the remaining covers.
5. Pay attention to the fact that there are marks on the bottoms of the pistons indicating which liners they belong to and how they should be installed. The arrow on the bottom of the piston with the word DIST should look at the end of the engine where the timing chain is located. The correct position of the piston is of great importance, as the hole for the piston pin is slightly offset from the central axis of the piston.
6. Do not attempt to disconnect the piston from the connecting rod. Firstly, after the piston is disconnected, it will need to be replaced with a new one, and secondly, a special device and a certain heating mode are required to connect the piston. If you want to replace pistons, connecting rods or connecting rod pins, you should contact a specialist.
7. Please note that the 5 crankshaft main bearing caps are numbered from "1" before "5" (from timing chain side). Remove 10 main cap mounting bolts.
8. Remove the main covers, leaving half of the bearing shells in them.
9. Lift the crankshaft out of the upper halves of the bearing shells. Unlike the lower ones, these liners have grooves. Remove the top bearings and set them aside with the corresponding lower bearings and main caps. Remove the 2 half thrust washers from bearing no. 2, paying attention to the fact that they are facing the grooved surface towards the crankshaft webs. Tag pucks (but not on the bearing surface), so as not to confuse them during installation. On the latest models, there are additionally 2 more half thrust washers, standing in the bearing cap N 2.
