If there is no stand, you can disassemble the engine by securing it on a sturdy workbench or floor. When disassembling without a stand, be very careful when performing operations on the engine.
If the engine is supposed to be repaired, then first all the units must be removed, so that they can be subsequently installed in the same order as during an independent overhaul. These units include the following:
- generator and brackets;
- exhaust gas toxicity reduction systems;
- ignition distributor, spark plugs and high-voltage wires;
- thermostat with housing;
- water pump;
- carburetor;
- intake and exhaust manifolds;
- oil filter;
- fuel pump;
- engine mount parts;
- flywheel with clutch mechanism.
Caution! When removing engine attachments, pay particular attention to any parts that may be needed for engine installation or for auxiliary mounting. Apply marks to gaskets, seals, spacers, shafts, washers, nuts to install them in their original position.
If an incomplete cylinder block is to be installed, i.e. a cylinder block with the crank mechanism and piston group installed, then the cylinder head, oil pan and oil pump must also be removed. The list of parts to be removed is determined by the accepted repair option.
If a complete overhaul is planned, the engine must be completely disassembled and the engine parts removed in the following order:
- timing belt covers for gas distribution mechanism drive;
- toothed belt;
- cylinder head cover;
- front and back covers;
- cylinder head and camshaft;
- oil pan;
- oil pump;
- connecting rod and piston group;
- crankshaft.
Before disassembling and performing major repair procedures, you will need the following tools and equipment:
- standard set of tools;
- small boxes or plastic bags for storing parts;
- spatula for removing gasket residue;
- countersink reamer;
- impact puller;
- micrometers;
- pointer indicator with mounting system;
- spring compressor;
- cylinder honing device;
- piston ring groove cleaning tool;
- electric drill;
- set of taps and dies;
- wire brushes;
- solvent.
Attention! New and repaired cylinder heads are available for sale. Since disassembly and inspection require specialized tools, and replacement parts are sometimes difficult to find, it is better to purchase a new cylinder head than to disassemble it, inspect it, and repair individual components.
