3.2.18. Tense device of a maple ridge belt

Removal

PERFORMANCE ORDER
1. Remove the hydraulic coupling of the fan.

Prevention

The cap nut has the left carving.


2. Remove a fan casing.
3. Remove maple a ridge belt.
4. Wring out a screw-driver a locking cover of a tension roller.
5. Unscrew a tension roller.
6. Engine in volume of 2,0 l: unscrew a remenny pulley of the pump of cooling liquid.
7. Unscrew the shock-absorber of the device of a tension of a belt.
8. Unhook a stretching spring.
9. Unscrew a konusny bolt from the lever of a tension of a spring, previously having wrung out a locking cover.
10. Remove the lever of a tension of a spring, track thus safety of a sealing ring and a prokladochny washer.

Installation

PERFORMANCE ORDER
1. Establish the lever of a tension of a spring with a sealing ring and a prokladochny washer and tighten with the moment of 100 N of m.
Prevention

Clear a carving a wire brush before installation and cover with hermetic (the carving needs to be degreased).


2. Insert a locking cover.
3. Hang a stretching spring.
4. Twirl the shock-absorber of the tense device above with the moment of 25 N of m, and below with the moment of 20 N of m.
Prevention

If establish the new shock-absorber, previously from it surely remove air. For this purpose in the provision of installation several times move backwards-forward a piston rod.


5. Engine in volume of 2,0 l: twirl a remenny pulley of the pump of cooling liquid with the moment of 10 N of m (a bolt with an internal shestigrannik) or 15 N of m (a torsionny bolt).
6. Screw a tension roller with the moment of 25 N of m (the engine of 2,0 l) or 30 N of m (the engine of 2,2/2,5 l). Insert a locking cover.
7. Establish maple a ridge belt.
8. Establish a fan casing.
9. Establish the hydraulic coupling of the fan.
