The main operations on repair of the engine are similar to operations on SOHC engine repair (see subsection 2).

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

Before engine repair it is necessary to remove from it:

– inlet and final collectors;
– arm of the pump of strengthening of a steering and generator;
– water pump;
– elements of fuel system;
– plait of wires and all electric switches, and sensors;
– oil filter;
– flywheel.

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

In need of carrying out complete major maintenance it is necessary to remove from the engine:

– inlet and final collectors;
– gear belt of a drive, pulleys and tension mechanism;
– head of the block of cylinders;
– flywheel;
– oil pallet;
– oil pump;
– pistons with rods;
– cranked shaft.
