Note: Before removing the piston + connecting rod combination, disconnect the cylinder head(s), oil pan and pump as recommended in the relevant sections of Chapter 2 of Part A or IN.
1. Completely remove the protrusion at the top of each cylinder using a special expanding tool (see picture). Trying to remove the piston + connecting rod combination without removing the protrusion may result in piston breakage.
2. After removing the protrusion, turn the engine over so that the corresponding part of the crankshaft is visible.
3. Before removing the connecting rods, check the end clearance with a feeler gauge. Insert the feeler gauges between the first connecting rod and the crankshaft until you find one of the appropriate thickness (see the figure). The end clearance is equal to the thickness of the feeler gauge. If the clearance exceeds the appropriate limit, new connecting rods must be installed. After installing new connecting rods (or a new crankshaft), the end clearance value may be below the permissible limit (in this case, the connecting rods should be treated by removing a layer of metal from them). Repeat the procedure for the remaining connecting rods.
4. Check the identification marks on the connecting rods and caps. If there is no single color marking, use a small punch to make a numerical mark on each connecting rod and cap.
5. Loosen each connecting rod nut a half turn until they can be loosened by hand. Remove the first connecting rod cap and bearing shell. Be careful not to drop the shell from the cap. Place a short piece of plastic or rubber hose over each bolt to protect the crankshaft journals and cylinder walls when removing the piston (see illustration). Push the piston and connecting rod assembly out the top of the engine. Use the handle of a wooden mallet to tap the upper bearing shell in the connecting rod. If resistance is felt, double-check to see if the lug in the cylinder has been removed.
6. Repeat the procedure for the remaining cylinders. After removal, reassemble the units from matching connecting rods, caps and bearing shells, tighten the cap nuts. This will help protect the connecting rod bearing surfaces from accidental impacts and scratches.
