To overhaul the engine, we disassemble the cylinder block.

Disassembly of the cylinder block was discussed in the article - "Disassembly of the cylinder block"

After disassembling the cylinder block, it is necessary to determine the possibility of further use of the cylinder block, crankshaft and piston group.

The piston pin is installed with an interference fit in the upper head of the connecting rod and rotates freely in the piston bosses.

The engines are equipped with SMP pistons.

Piston pins are installed with an interference fit in the upper heads of the connecting rods and rotate freely in the piston bosses, so heat the upper head of the connecting rod to a temperature of 250˚ C

After we have prepared the nodes and the parts for assembling the cylinder block, we proceed to the assembly.

The assembly of a connecting rod with a piston is discussed in the article - "Piston assembly" .

Installing pistons with connecting rods

Lubricate the tops of the cylinders and the crankpins with engine oil.
