3.1.4.2.5. Assembly of the CVH 1,8 engine of dm3

GENERAL INFORMATION

Prevention

Only the difference in comparison with the ONS engine is given.


Krivoshipno-shatunny CVH engine mechanism

1 – the piston with a finger and piston rings,
2 – rod,
3 – connecting rods,
4 – inserts of radical bearings,
5 – persistent half rings of a bent shaft,
6 – bent shaft,
7 – back sealing ring of a bent shaft,
8 – forward sealing ring of a bent shaft

CVH engine lubrication system

1 – oil filter,
2 – indexes of level of oil (with the alarm system
and without level alarm system),
3 – guide of the index of level of oil,
4 – oil pressure sensor,
5 – oil pump,
6 – oil return pipeline,
7 – laying,
8 – the pipeline of supply of oil to the pump,
9 – laying

After extraction of halves of inserts of radical bearings and persistent half rings of a bent shaft it is necessary to take from system of ventilation of a case an oil separator together with its spring.

Removal of a separator of oil from system of ventilation of a case of the CVH engine


Removal and installation of the oil pump

PERFORMANCE ORDER
1. To merge oil from the oil pallet.
2. To remove a casing of the drive of system of gas distribution and a gear belt.
3. To remove from a bent shaft maple a pulley, a pulley and the oil pallet.
4. To unscrew bolts of fastening of the oil pump and to remove the pump.
5. To wash up the oil pallet and a mesh oil filter, and then to perform operations in the return sequence in relation to removal process.
6. To put on a gear belt, paying attention to coincidence of signs on a bent shaft and a cam-shaft.

Removal of the pump of cooling liquid

PERFORMANCE ORDER
1. To disconnect a wire of weight from the accumulator and to merge liquid from the cooling system.
2. To take off maple a generator drive belt.
3. To rotate a bent shaft before coincidence of adjusting signs VMT of the piston of the 1st cylinder on a pulley of a bent shaft and a casing of the drive of system of gas distribution, and then to remove a casing of the drive of system of gas distribution.
4. To weaken the tension device and to take off a gear belt.
5. To disconnect the elastic pipeline of cooling liquid going to a radiator and the pipeline of cooling liquid going to a contour of heating of interior of the car.
6. To remove the tension device of a gear belt.
7. To unscrew four bolts of fastening of the pump of cooling liquid to the block of cylinders of the engine and to take the pump of cooling liquid.

Installation of the pump of cooling liquid

PERFORMANCE ORDER
1. To clear a laying prileganiye surface on the pump of cooling liquid and the block of cylinders of the engine.
2. To establish new laying and to screw the pump of cooling liquid on the block of cylinders of the engine.
3. To install the tension device of a gear belt.
4. To put on a gear belt.
5. To establish a casing of the drive of system of gas distribution.
6. To put on maple a belt of the drive of the generator and to pull it.
7. To connect elastic cooling systems of the pipeline, to fill the cooling system and to check its tightness.
