If a stand is not available, disassembly should be performed with the engine placed on a sturdy workbench or securely placed on a solid garage floor. When working without a stand, make sure that the engine does not accidentally tip over.
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 unit. The components that need to be re-installed include:
- a) Generator with brackets;
- b) Steering pump with brackets;
- c) Components of emission control systems;
- d) Distributor, high voltage wires and spark plugs;
- e) Thermostat with casing cover;
- f) Water pump bypass pipe/hose;
- g) Fuel injection system components;
- h) Inlet manifold and outlet manifold(s);
- i) Oil filter;
- j) Powertrain suspension supports;
- k) Clutch assembly (manual transmission);
- l) Flywheel/drive disk;
Note: When removing external components from an old engine, try to remember the characteristic features of their installation. Record in a notebook the mounting positions of gaskets, seals, spacers and bushings, pins, brackets, washers, bolts and other small parts.
When choosing a scheme using a reduced block kit consisting of a cylinder block with a crankshaft and connecting rod and piston groups installed in it, also remove the cylinder head, oil pan and oil pump from the old unit (see Section 1 for possible alternative schemes for performing major repairs) Alternative options for engine repair schemes).
When performing a complete overhaul of an old unit, disassemble it and remove all internal components. The optimal order for performing the engine disassembly procedure is given below:
- a) Intake manifold and exhaust manifold(s);
- b) Cylinder head cover(s);
- c) Timing belt covers with bolts;
- d) Timing drive (timing belt with toothed wheels);
- e) Assembling the rocker arms with the camshaft(s);
- f) Cylinder head(s);
- g) Water pump;
- h) Oil pan;
- i) Oil intake with mesh filter;
- j) Front cover/oil pump;
- k) Connecting rod and piston assemblies;
- l) Crankshaft and main bearings;
Before you begin disassembling the engine, prepare the following materials, tools and parts (see also Section Engine assembly procedure):
- a) Standard set of locksmith tools;
- b) A set of cardboard or plastic containers/polyethylene bags for organized storage of small components;
- c) Scraper for cleaning mating surfaces;
- d) Countersink for removing stepped wear on the top of the cylinders;
- e) Puller for dismantling the torsional vibration damper;
- f) Set of micrometers;
- g) Telescopic bore gauge;
- h) Dial plunger type meter (DTI);
- i) Valve spring compressor tool;
- j) Honing for processing cylinder mirrors;
- k) Tool for cleaning grooves for installing piston rings;
- l) Electric drill;
- m) Set of taps and guides;
- n) Wire brushes;
- o) Cylindrical brushes for cleaning oil galleries;
- p) Solvent.
