THE GENERAL DATA

THE PETROL ENGINE

The 6-cylinder petrol engine


1. The oil pump. Soaks up engine oil through soaking up filter and soaking up pipe from the oil pallet
2. The longitudinal oil channel to the oil filter
5. The main oil channel
To basic sites
6. Oil jets. Engine oil is injected from below for cooling in a direction to the bases of pistons
7. The delivery pipeline to натяжителю chains
8. The return blocking valve
9. Натяжитель chains
10. An aperture for an exit of gases in a sealing lining of a head of the block of cylinders
14. An oil jet for an operating chain
15. The delivery pipeline to a head of the block of cylinders
17. An oil throttle. Internal diameter of 4 mm
22. The oil channel. For greasing 12 тарельчатых pushers on the release party
23. The oil channel. For greasing 12 тарельчатых pushers on the admission party
27. A camshaft regulator
30. Hydraulic тарельчатый a pusher
And. The oil channel from the oil pump to an oil radiator
b. The oil channel from the oil filter to basic surfaces
With. A drain aperture in the oil pallet

Oil редукционный the valve is in the channel between the chamber всасывания and the chamber of compression of the oil pump. If pressure of oil from above 5 bar, the valve opens, and the oil part can back join the chamber всасывания the pump.

If at normal level of oil its pressure too little, check up the valve.

Removal
1. A vinitovaja stopper, SW22
2. A compression spring
3. A directing finger
4. The piston

PERFORMANCE ORDER
1. Disassemble the oil pallet.
2. Unscrew a screw stopper wrench SW22.
The prevention

The screw stopper is under the pressure of a spring of compression and can easily jump out.


3. Take the compression spring, directing finger and the piston.
The prevention

Тугоподвижный or the jammed piston it is possible to take by means of ring pincers.


4. Clean an aperture in the oil pump and blow compressed air.
5. The piston of an aperture of the oil pump some times move backwards-forward. If the piston moves hardly, slightly level its polishing cloth.

Installation

PERFORMANCE ORDER
1. If replace the piston check up ease of its course in an aperture. If necessary, remove agnails in the piston наждачным a cloth.
2. Establish the piston with a directing finger and a new spring of compression.
3. Screw up a screw stopper without a sealing ring and tighten with the moment 50 Н.м.

THE DIESEL ENGINE

Oil редукционный the valve is in the connecting channel between chambers of compression and всасывания the oil pump. If pressure exceeds 5 bar, the valve opens, and the oil part is poured in soaking up chamber. The valve should be checked, if at normal level of oil its pressure too low.

Removal


249. A vinitovaja stopper, 50 Н.м.
250. A directing finger
251. A compression spring
252. The piston

PERFORMANCE ORDER
1. Remove the oil pallet.
2. Unscrew a screw stopper.
The prevention

The screw stopper is under the pressure of a spring of compression and can easily jump out.


3. Take the compression spring, directing finger and the piston.
The prevention

Тугоподвижный or the jammed piston take out by means of an external ring grip.


4. Clean the cylinder of the oil pump and blow compressed air.
5. Some times move backwards-forward the piston in the cylinder of the oil pump. If the piston hard moves in the cylinder slightly polish the piston on fabric притире.

Installation

PERFORMANCE ORDER
1. If the piston is replaced new, check up the new piston on ease of a course in the cylinder. In case of need remove agnails on the piston наждачным a cloth.
2. Establish the piston with a directing finger and a new spring of compression.
3. Twist a stopper without a sealing ring and tighten with the moment 50 Н.м. The screw stopper is condensed конусной with landing.
