2. If there is no stand, you can disassemble the engine on a stand, workbench or even on the floor, placing it steadily on props. When working without a stand, be careful that the engine does not tip over or fall.
3. If you are going to purchase a remanufactured engine, first of all, remove all external parts from the old engine for their subsequent installation on a new engine (if you want to do all the other work yourself). These outdoor parts include:
- A) Wiring harnesses and engine mount brackets.
- b) Brackets for fastening the generator, starter, oil filter, power steering pump, etc.
- V) Thermostat and its body.
- G) Oil dipstick tube.
- d) All electrical switches and sensors.
- e) Intake and exhaust manifolds.
- and) Coils and spark plugs.
- h) Flywheel or faceplate.
Note: When removing external parts from the engine, pay attention to the installation features that may be useful during assembly. Notice the position of gaskets, cuffs, bolts, washers and other small things.
4. If you purchase an engine in "small set", which includes a cylinder block assembly with a crankcase, crankshaft, pistons and connecting rods, it is also necessary to remove the cylinder head, oil pan, oil pump and camshaft drive chain from the old engine.
5. If a complete overhaul of the engine is planned, then it can be disassembled in the following order.
- A) intake and exhaust manifolds (see chapter 4A).
- b) Camshaft drive mechanism (chain, sprockets and tensioner).
- V) Cylinder head.
- G) Flywheel / faceplate.
- d) Oil pan.
- e) Oil pump.
- and) Pistons with connecting rods (see paragraph 9 of this chapter).
- h) Crankshaft (see paragraph 10 of this chapter).
6. Before starting disassembly and repair, make sure that you have all the necessary tools. For further information, see the section "Tools and fixtures" at the end of the book.
