3.2.17. Maple ridge belt

GENERAL INFORMATION

Maple belt (a standard design)

1. Tension roller
2. Remenny pulley of a cranked shaft
5. Remenny pulley of the generator of a three-phase current
7. Remenny pulley of the pump of the amplifier of a steering
8. The Remenny pulley of the pump of cooling liquid

The maple belt puts in action all additional units of the engine. Ridge maple the belt is wider, than usual maple the belt and has many edges on inside. Ridge maple the belt stretches by means of the automatic tense device consisting of a spring of stretching, a tension roller and the shock-absorber. The shock-absorber provides a uniform tension of a belt in all range of turns of the engine. Depending on the equipment of the car maple the belt has various length.

Removal


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

Prevention

The cap nut has the left carving.


2. Release tense device, turn off a nut with a fillet (378).
3. Insert into an opening of the lever of a tension of a spring (374) core and press them against effort of a spring of stretching (380) to the left (in the direction masloizmeritelny щупа) while the bolt (375) will not unload so that it it will be possible вытолкнуть in the direction of an inlet pipe. As a core it is possible to use a wrench from the onboard tool of the car or the lever in length about 300 mm and diameter of 12-13 mm.
4. Slowly release the lever of a tension of a spring, wring out a tension roller and remove maple a belt.

Installation

PERFORMANCE ORDER
1. Check profiles of belt pulleys on absence of damages and pollution if it is necessary, clean or replace pulleys. Thus pay attention to holes in belt pulleys and the loosened places of fastening of the tense device.
2. In the presence of holes on a pulley replace it. Replace also the tension device if fastening support are loosened.
3. The ridge maple belts having pollution between ledges of edges, belts with cross-section cracks and the broken edges surely replace.
4. Slightly raise a tension roller, turn a belt from the back party so that the small loop was formed, and push it between belt pulleys of the pump of cooling liquid and a cranked shaft.
5. Strong press ridge maple a belt to a belt pulley of the pump of cooling liquid and at the same time turn a remenny pulley to the left (shooter) while the belt will not appear on a tension roller.

6. Impose maple a ridge belt on a tension roller and a remenny pulley of a cranked shaft. Then, turning a free part of a belt, impose it on belt pulleys of the cooling compressor, the pump of the amplifier of a steering, the pump of cooling liquid and the generator of a three-phase current.

7. By means of a core (1) turn to the left the lever of a tension of a spring (2) while it will allow a bolt (3). So the belt tension is carried out. (4–a stretching spring)
8. Tighten a nut with a fillet (1).

9. Check durability of landing of a maple ridge belt on belt pulleys.

10. Establish the hydraulic coupling of the fan.
