If in the conversation between the drivers phrases are heard: "to sort out the engine", "overhaul of the engine", then the engine has already outlived its usefulness. As a rule, in the process of repairing this automotive unit, most of the parts of the old engine are thrown away and replaced with new ones.
Necessary
- - spare parts;
- - tools.
Instructions
Step 1
Remove the engine. Then remove the bolt securing the frame, which is installed to remove the engine. Then loosen the clamp and disconnect the fuel pump hose.
Step 2
Unscrew the nuts securing the fuel pump, then remove the pump, the spacer (it is installed under the pump) and the gasket (located between the BC and the spacer). Then remove the wires going to the spark plugs and unscrew the nut that secures the ignition distributor.
Step 3
Remove the KRZ plate. Disconnect the hose from the vacuum regulator, then remove the ignition distributor. Then remove the generator and remove the belt from the pulleys, and then remove the carburetor hose and the hose designed to supply vacuum to the vacuum regulator, as well as the hose of the crankcase ventilation system.
Step 4
Carefully loosen the oil filter tightening, remove the breather cap, then remove the pressure sensor, then the crankshaft pulley. If a gasket remains on the BC, be sure to remove it. Then unfold the tabs of the lock washers.
Step 5
Remove the cylinder head fixing bolts and remove the flywheel. Then remove the oil sump gasket and the pump itself. Then remove the drive gear and oil separator with drain tube.
Step 6
Remove the pistons and connecting rods, then remove the main bearing cap and crankshaft. Remove the bushings and upper compression ring from all connecting rods. Then remove the remaining rings and pull out the piston pin.
Step 7
Use a hammer to dislodge the piston pin. But this should be done carefully so as not to damage the part. You will need a lathe to process the block: boring can take several hours.
Step 8
Heat the connecting rod necks in oil to press the new fingers into the pots. Then put the rings on them. After replacing all defective parts, reassemble the engine in reverse order.
