We disassemble the block head for subsequent repair or replacement.
When disassembling, you need to lay out the spare parts of the head in order, taking into account their further use.
Usually, we start checking and replacing hydraulic pushers when increased engine noise occurs.
This is usually a ringing sound at the top of the engine.
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.
Below are the catalog numbers of the original spare parts that are most in demand during maintenance and repair of the engine.
The main dimensions of the crankshaft are given in Figure 1.
Crankshaft - cast, cast iron, five-bearing.
It is possible to regrind the crankshaft journals during repairs with a diameter reduction of 0.25; 0.5; 0.75; and 1 mm.
The fuel supply system filters the fuel and distributes it evenly among the engine cylinders in metered portions at strictly defined moments
The main dimensions of the connecting rod and piston group are shown in Figure 1.
The piston is cast aluminum. The mass of the pistons is strictly maintained in the manufacture.
