Dismantling of a drive of the gas-distributing mechanism

 PERFORMANCE ORDER

We merge from the engine oil and cooling liquid, we remove a mudguard and a belt of a drive of auxiliary units (see appropriate sections).
We remove a radiator, the fan, the pump of cooling liquid and the generator (see appropriate sections).
We remove a pulley of a cranked shaft (see. Replacement of a forward cuff of a cranked shaft).
The forward cover of the block of cylinders can be removed, without removing a head. But damage of laying of a head as at assembly glue-hermetic was put on the top end face of a cover of the block of cylinders is thus possible. Besides, the head disturbs at cover installation — difficultly to achieve exact centering of a cuff on the plug of a cranked shaft that will result in its fast wear. Therefore, assorting a drive of the gas-distributing mechanism, we remove a block head (see. Removal of a head of the block of cylinders).

Head «on 14» we turn on four bolts of fastening of the amplifier of a case of coupling to the block.

Keys «on 14» and «on 17» we turn on two bolts of fastening of the amplifier to a coupling case …

… also we remove the amplifier.

Head «on 13» we turn on four nuts...

... and a key «on 12» – eleven bolts of fastening of the pallet of a case to the block of cylinders.

Accurately, trying not to damage laying, we remove the pallet from hairpins and we put on a cross-piece.

We remove a gidronatyazhitel of the bottom chain (see. Removal and installation of gidronatyazhitel).

Six-sided key «on 6» we turn on seven screws of fastening of a cover of the block of cylinders.

Having hooked a screw-driver, we uncover.

Six-sided key «on 6» we turn on an axis of a boot of a gidronatyazhitel of the top chain, holding the extension piece a key «on 14».

We remove a boot of a natyazhitel.

We remove the top chain from an asterisk of an intermediate shaft.

If necessary a key «on 14» we turn on the extension piece of an axis of a boot.

Six-sided key «on 6» we turn out an axis of a boot of the bottom gidronatyazhitel and we remove a boot.

Chisel we unbend edges of a lock plate.

Screw-driver holding an asterisk of an intermediate shaft, a key «on 12» we turn on two bolts.

We remove an asterisk together with the bottom chain from an axis of an intermediate shaft.

Six-sided key «on 6» we turn on two screws and we remove an uspokoitel of the bottom chain.

Before assembly of a drive of the gas-distributing mechanism we clear the privalochny planes of the block of cylinders and a chain cover of the laying and hermetic remains.
Assembly we carry out in return sequence.

Asterisks of intermediate and cranked shaft should be exposed on marks (see. Engine assembly).
