The easiest way to disassemble the engine is to install it on a special mounting stand, which you can try to rent from a car service workshop. To install it on the stand, the flywheel is removed from the engine, after which the mounting bolts are screwed into the holes in the end of the cylinder block.
If there is no stand, the engine can be installed on a sturdy workbench, or directly on the garage floor - work carefully, trying not to hit the crankcase on hard surfaces.
When using a fully reconditioned unit, all auxiliary units and attachments should be transferred to it. The following components are subject to transfer:
Petrol engines
- a) Steering pump (if equipped accordingly - see Chapter Suspension and steering);
- b) Compressor K/V (see Chapter Cooling and heating systems);
- c) Generator (with support brackets) and starter (see Chapter Engine electrical equipment);
- d) High voltage wires and components of the ignition system, including all sensors, distributor, spark plugs, etc., depending on the configuration (see Chapter Engine electrical equipment);
- e) Components of the power supply system (see Chapter Power supply system);
- f) All electrical sensors, switches and actuators, as well as the main engine wiring harness (see Chapter Power supply system, Chapter Engine electrical equipment Chapter On-board electrical equipment);
- g) Inlet manifold and outlet manifold (see Chapter Power supply system);
- h) Engine oil level dipstick with guide tube;
- i) Powertrain supports;
- j) Flywheel;
- k) Clutch components (see Chapter Clutch).
Diesel engines
- a) Steering pump (if equipped accordingly - see Chapter Suspension and steering);
- b) Compressor K/V (see Chapter Cooling and heating systems);
- c) Generator (with support brackets) and starter (see Chapter Engine electrical equipment);
- d) Glow plugs/pre-glow system components (see Chapter Engine electrical equipment);
- e) All components of the fuel system, including fuel injection pumps, sensors and actuators (see Chapter Power supply system);
- f) Brake booster vacuum pump (see Chapter Brake system);
- g) All electrical sensors, switches and actuators, as well as the main engine wiring harness (see Chapter Power supply system Chapter On-board electrical equipment);
- h) Inlet manifold and outlet manifold (see relevant Section of Chapter Power supply system);
- i) Engine oil level dipstick with guide tube;
- j) Powertrain supports;
- k) Flywheel;
- l) Clutch components (see Chapter Clutch).
Note: When removing add-on components, pay attention to the smallest details of their installation, which may be useful during assembly. Try to remember the installation positions of all gaskets, seals, spacers, pins, washers, bolts and other small parts.
In case of purchasing an incomplete set (cylinder block with crankshaft and piston group), it is also necessary to remove from the old engine the cylinder head, oil pan with oil deflector, oil pump, timing belt/chain with covers, auxiliary drive belt, water pump, thermostat housing, cooling tract pipes, air cleaner housing and, if equipped, oil cooler.
In preparation for a complete overhaul, the engine is disassembled in the following order:
- a) Intake manifold and exhaust manifold;
- b) Timing chain/belt with sprockets/toothed wheels and tensioner;
- c) Cylinder head;
- d) Oil pan;
- e) Oil pump;
- f) Assemblies of pistons with connecting rods;
- g) Crankshaft.
