GENERAL INFORMATION

It is the most convenient to perform works on the engine if it is installed on a special bed.

Before repair of the engine it is necessary to remove from it:

 – generator;
 – thermostat and branch pipe of an exit of cooling liquid (petrol engines);

If it is necessary to make only repair of the block of cylinders, the crankshaft, pistons and rods, then it is necessary to remove a head of the block of cylinders, the oil pallet, the oil pump and a gear belt.

 – inlet and final collectors;
 – gear belt, pulleys and mechanism of a tension;
 – head of the block of cylinders;
 – flywheel;
 – oil pallet;
 – oil pump;
