If there is no stand, then you can disassemble the engine by securing it on a sturdy workbench or on the floor. When disassembling without a stand, be very careful when handling the engine.
If the engine is to be repaired, then first all the units must be removed in order to install them later in exactly the same order as during an independent overhaul. These units include:
- 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 installation. Mark gaskets, seals, spacers, shafts, washers, nuts, etc. to return them to their original positions. 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:
