Dismantling and overhaul of the engine — general information This subsection discusses in detail the procedure for performing such work as dismantling the power unit from the car and overhauling the internal parts of the engines in question. Part of the procedures for removing...
Engine Specifications 2F and 3F-E engines (data for 3F-E motors are in brackets) Compression: – standard 9.8 kgf/cm 2 (9,8) - the greatest difference in compression in the cylinders 2.0 kgf/cm 2 (2,0) Oil pressure: - at idle (600 rpm) not...
Engine diagnostics with a vacuum gauge 1. Vacuum measurement is a reliable and relatively cheap way to diagnose an engine. According to the readings of the vacuum gauge, you can get an idea about the condition of the piston group, the tightness of the...
Cylinder compression check The results of the compression test in the engine cylinders allow you to judge the condition of the engine parts (pistons, rings, valves and seats, cylinder head gaskets). To obtain accurate test results, the engine...
Dismantling the power unit The engine is removed from the engine compartment by lifting, so the lifting equipment must be sized for the weight of the engine. Work should be carried out with an assistant who has certain skills. On injection...
Removal and installation of the engine Removing 1. Decompress the fuel system and disconnect the battery from the ground. 2. Remove the air filter. 3. Drain the coolant. 4. Label and disconnect all wiring connectors, vacuum and fuel hoses from the engine....
Overhaul Alternatives There are a number of options available for a major overhaul. The determining factor is the condition of the cylinder block, which in some cases it is advisable to replace. If the condition of the crank mechanism and...
Engine disassembly procedure Crank mechanism and piston group of 3F-E engines (2F motor arrangement is similar) 1. Lower compression ring; 2. Oil scraper ring expander; 3. Finger; 4. Connecting rod head bushing; 5. Camshaft bearing; 6. Compensation...
Cylinder head — disassembly, inspection and assembly Valve train parts 1. Crackers; 2. Plates; 3. Springs; 4. Umbrella caps; 5. Valves Disassembly Attention! It seems more appropriate to purchase a new block head than to disassemble, check and repair a used head. 1. To...
Valve repair — general information Due to the complexity of the work and the need to use special tools and equipment, it is recommended to repair valves, seats and guide bushings in a car service. It is advisable to independently carry out only...
Connecting rod and piston group — disassembly Attention! Before removing the pistons and connecting rods, remove the cylinder head, oil pan and oil pump. 1. Remove the shoulder formed as a result of the development and deposits of soot in the upper part of the...
Crankshaft — removal and inspection Dismantling Attention! The crankshaft can only be removed after the engine has been removed from the vehicle. Remove the flywheel first (or master disk), idler pulley, belt (chain), sump, oil receiver, oil pump, front...
Cleaning and checking the cylinder block Telescopic inside diameter gauge Cleaning Attention! The plugs of the channels of the cooling system are tightly pressed into the cylinder block. 1. Remove lids with liners, label them and store separately. 2. Carefully...
Cylinder honing 1. For honing it is recommended to use "brush". 2. Clamp the fixture into an electric drill. 3. Lubricate the surface of the cylinder well with oil, turn on the electric drill and periodically move up and down in the...
Connecting rods and pistons — check 1. Carefully clean the pistons from carbon deposits and carefully remove the rings. 2. Remove carbon deposits from the piston ring grooves using a tool (photo on the left) or old piston ring (photo on the right). 3....
Main and connecting rod bearings Main and connecting rod bearings must be replaced during engine overhauls, but used bearings should be carefully checked to restore the general condition of the engine at the time of repair. Causes of destruction of...
Engine assembly procedure The following assembly order for the engines in question is recommended: camshaft bearings (pressed in a car service); piston rings; crankshaft and main bearings; pistons with connecting rods; oil pump; camshafts and...
Installation of piston rings 1. Before installing new piston rings, sort the rings and check the gap in the joints (here on the left). To do this, push the ring through the piston head (photo on the right). The ring should be at the bottom of the...
Crankshaft — installation and inspection Installation 1. Position the block so that the bottom is facing up. 2. Turn out bolts of covers, get covers and lay them out in the order of their installation. 3. Remove the old liners from the covers and cylinder...
Rear oil seal — installation 1. Check the condition of the crankshaft journal. In the case of deep wear in the place of the edges of the stuffing box, it is recommended to replace the crankshaft. 2. Clean the groove under the oil seal in the...
Connecting rods and pistons — installation and assembly Arrangement of joints of piston rings 1. The upper disk of the oil scraper ring; 2. Top compression ring; 3. The lower disk of the oil scraper ring; 4. Lower compression ring; 5. Oil scraper ring expander; 6. Notch...
Starting the engine after repair and running in 1. After assembly is complete, double check the oil and coolant levels. 2. With the candles turned out and the ignition system turned off, turn the crankshaft until the oil pressure is registered by the sensor. 3. Screw...
