To do the job, you need a soft metal bar with a diameter of 21 mm.
Disassembly
1. Remove the piston rings from the piston (see "Piston rings and connecting rod bearings - replacement").
2. With an awl, we hook and remove the piston pin retaining rings from the grooves.
3. With a soft metal bar of a suitable diameter, we push out the piston pin.
4. Remove the piston from the connecting rod.
Assembly
1. We assemble the piston with the connecting rod in the reverse order. After assembling the connecting rod with the piston, the cylinder number on the connecting rod and its cover should be on the right side of the piston when looking at the arrow stamped on it. When installing the piston in the cylinder, the connecting rod with the cylinder number should face the side of the block on which the tide for installing the oil filter is located, and with the catalog number towards the front end of the crankshaft.
2. We put rings on the piston and install the piston in the cylinder (see "Piston rings and connecting rod bearings - replacement").
