2. If there is no opportunity to use the stand, disassembly should be done by placing the engine on a solid workbench, or by placing it securely on a hard garage floor. When working without a stand, make sure that the engine does not accidentally tip over.
3. If you plan to replace the engine with a remanufactured one, remove all attachments and external components from the old one and transfer them to the replacement block. The components to be changed include:
- a) Generator with brackets;
- b) Components of systems for reducing the toxicity of exhaust gases;
- c) Distributor/coil assembly and spark plugs with BB wires;
- d) Thermostat with casing cover;
- e) Water pump;
- f) Injection system components (EFI);
- g) Inlet pipeline and exhaust manifold (s);
- h) Oil filter;
- i) Suspension support of the power unit;
- j) Clutch Assembly (RKPP);
- k) Flywheel/Drive Disc;
- l) Back plate of the engine.
Note. When removing external components from an old engine, try to remember the characteristic features of their installation. Record the seating positions of gaskets, seals, distance rings and bushings, pins, brackets, washers, bolts and other small parts in a notebook.
4. When choosing a scheme using an abbreviated block set consisting of a cylinder block with a crankshaft and connecting rod and piston groups installed in it, also remove the head from the old unit (And) cylinders, oil pan and oil pump (for possible alternatives to overhaul schemes see Section Alternative options for engine reconditioning schemes).
5. When carrying out a complete overhaul of an old unit, disassemble it and remove all internal components. The following is the best order for removing components when performing an engine disassembly procedure:
- a) Inlet pipeline and exhaust manifold (s);
- b) Lid (And) cylinder heads;
- c) Timing drive covers with bolts;
- d) front cover (And) and timing drive components (timing belt with gears;
- e) Head (And) cylinders;
- f) Oil pan;
- g) Oil pump;
- h) Balance Assembly (with appropriate equipment);
- i) Connecting rod and piston assemblies;
- j) Rear crankshaft oil seal with holder;
- k) crankshaft and main bearings;
6. Before disassembling the engine, prepare the materials and tools that will be required when assembling the unit (see Section Useful tips for engine reconditioning).
