3.31. Dismantle of the conrod and piston group (CPG) of the engine on the car

 PERFORMANCE ORDER

If necessary dismantle of ShPG of the engine can be executed on the car, without removing the engine.

Work is carried out on a viewing ditch or the elevator.
We remove the engine case pallet (see Removal of the pallet of a case and the oil pump of the engine on the car).

Head "on 14" we turn off two nuts of fastening of a cover of a rod (the piston at the same time has to be in NMT).

With plastic brisk (or the hammer with brisk of soft metal) we strike with the hammer easy blows to side surfaces of a cover to weaken its landing on conrod bolts.

We uncover a rod.

We shift a rod up.

Resting the wooden handle of the hammer against the socket of the lower head of a rod, we push a rod up to a piston exit from the cylinder...

... also we take out the piston with a rod assembled.

Similarly we dismantle pistons with rods of other cylinders.
The ShPG installation is carried out in the return sequence (see also Dismantling and assembly of the engine).

Before installation of the piston with a rod in the cylinder a mandrel it is squeezed piston rings.

We install a rod with the piston in the cylinder.

Resting the hammer handle against the piston bottom, we push the piston in the cylinder.

Further assembly is carried out in the return sequence.
