2. If there is no stand, you can disassemble the engine on a stand, workbench, or even on the floor, placing it securely on supports. When working without a stand, be careful that the engine does not tip over or fall.
3. If you are going to buy a rebuilt engine, first remove all external parts from the old engine for subsequent installation on the new engine (if you want to do all the other work yourself). These exterior parts include:
- a) Wiring harnesses and engine mount brackets.
- b) Mounting brackets for the generator, starter, oil filter, power steering pump, etc.
- c) Thermostat and its housing.
- d) Oil dipstick tube.
- d) All electrical switches and sensors.
- e) Intake and exhaust manifolds.
- g) 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. Note the position of gaskets, seals, bolts, washers and other small items.
4. If you purchase an engine in a "small kit", which includes a cylinder block complete with a crankcase, crankshaft, pistons and connecting rods, then you must also 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, it can be disassembled in the following order.
- a) Intake and exhaust manifolds (see chapter 4A).
- b) Camshaft drive mechanism (chain, sprockets and tensioner).
- c) Cylinder head.
- d) Flywheel/faceplate.
- d) Oil pan.
- e) Oil pump.
- g) Pistons with connecting rods (see paragraph 9 of this chapter).
- c) Crankshaft (see paragraph 10 of this chapter).
6. Before you begin disassembling and repairing, make sure you have all the necessary tools. For further information, see the "Tools and Accessories" section at the end of the book.
