GENERAL INFORMATION

Arrangement of bolts of fastening of a cover of a chain to the block of cylinders of the engine

Bolts of fastening are specified by shooters.

Removal

PERFORMANCE ORDER

1. Remove the top cover of a chain of the drive of the mechanism of gas distribution and an asterisk.
2. Remove a head of the block of cylinders. It is theoretically possible to uncover a gas distribution mechanism chain without removal of a head of the block of cylinders, however in this case the probability of damage of laying of a head of the block of cylinders is high.
3. Remove the cooling system pump.
4. Remove a pulley of a bent shaft. When weakening a bolt of fastening of a pulley temporarily take a pulley of blocking of a bent shaft, and after removal of a pulley establish into place a blocking pin.
5. Remove the oil pallet.
6. Remove the generator.
7. Remove the pump of the amplifier of steering.
8. Unscrew the lower head of a natyazhitel of a chain and take a chain tension mechanism plunger.
9. Unscrew bolts of fastening of a cover of a chain to the block of cylinders of the engine and uncover. Keep in mind that bolts have different length.
	10. Unscrew a hinged bolt and remove top (1) and the lower (2) natyazhitel of a chain.
	11. Unscrew bolts (are specified by shooters) and remove the lower guide of a chain from the block of cylinders.
	12. Temporarily remove an asterisk from the fuel pump and remove laying of a cover of a chain then establish an asterisk into place.

Installation

PERFORMANCE ORDER

1. Replace an oil sealing ring of a bent shaft.
2. Check that the interfaced surfaces of a cover and a head of the block of cylinders, the pure and dry and directing pins are in the nests.
3. Temporarily remove an asterisk from a shaft of the fuel pump, establish laying and arrange it on the directing probes. Establish an asterisk on a shaft of the fuel pump.
	4. Establish the lower guide of a chain.
	5. Establish natyazhitel of a chain and fix them by a hinged bolt.
6. Establish a chain cover into place, combine the drive of the oil pump with an asterisk of a bent shaft and pull a cover over the directing pins.
7. Gradually and consistently tighten bolts of fastening of a cover of a chain.
8. Establish a new sealing ring to the lower head of a natyazhitel of a chain.
9. Establish a pulley of a bent shaft.
10. Establish a head of the block of cylinders.
11. Establish the top cover of a chain and an asterisk.
12. Install the oil pallet.
