1.5.5.2. Replacement of an auxiliary driving belt on the 4-cylinder engine

GENERAL INFORMATION

Arrangement of a bolt of fastening of the mechanism of a tension of an auxiliary driving belt (1) and nut of a regulator (2) on 4-cylinder engines

Arrangement of an auxiliary driving belt on the 4-cylinder engine without the amplifier of a steering

Sequence of installation of a driving belt on pulleys:

1–pulley of the mechanism of a tension;
2–pulley of a cranked shaft;
3–generator pulley;
4–water pump

Arrangement of an auxiliary driving belt on the 4-cylinder engine with the amplifier of a steering, but without air central air

Sequence of installation of a driving belt on pulleys:

1–pulley of the mechanism of a tension;
2–pulley of a cranked shaft;
3–generator pulley;
4–pulley of the pump of the amplifier of a steering;
5–pulley of the water pump

Arrangement of an auxiliary driving belt on the 4-cylinder engine with the amplifier of a steering and air conditioning

Sequence of installation of a driving belt on pulleys:

1–pulley of the mechanism of a tension;
2–pulley of a cranked shaft;
3–pulley of the compressor of central air;
4–generator pulley;
5–pulley of the pump of the amplifier of a steering;
6–pulley of the water pump

PERFORMANCE ORDER
1. Remove a krylchatka of the fan of a radiator and a casing.
2. Weaken a bolt of fastening of the mechanism of a tension of an auxiliary belt on a turn quarter (see fig. An arrangement of a bolt of fastening of the mechanism of a tension of an auxiliary driving belt (1) and a nut of a regulator (2) on 4-cylinder engines).
3. Rotating counter-clockwise, weaken a nut of a regulator and unscrew a regulator so that the auxiliary driving belt was completely weakened. Remove an auxiliary driving belt from pulleys.
4. Establish a new driving belt on pulleys, since a mechanism pulley on tyazheniye and further in the sequence shown in drawings the Arrangement of an auxiliary driving belt on the 4-cylinder engine without the amplifier of a steering, the Arrangement of an auxiliary driving belt on the 4-cylinder engine with the amplifier of a steering, but without air central air, the Arrangement of an auxiliary driving belt on the 4-cylinder engine with the amplifier of a steering and air conditioning.
5. Adjust a tension of an auxiliary driving belt as follows.

Models with a large-scale ruler on the tension mechanism

Adjustment of a tension of an auxiliary belt on 4-cylinder engines
For adjustment of a tension of an auxiliary belt on 4-cylinder engines rotate a nut of a regulator (1) before combination of the index (2) with the fifth label on a large-scale ruler (3).

PERFORMANCE ORDER
1. On cars without the amplifier of a steering rotate a regulator nut clockwise before combination of the index of the mechanism of a tension with the fifth label at the left on a large-scale scale (see fig. Adjustment of a tension of an auxiliary belt on 4-cylinder engines).
2. On models with the amplifier of a steering rotate a regulator nut clockwise until the index of the mechanism of a tension will not be established between the 8th and 9th label at the left on a large-scale ruler.
3. Tighten a bolt of fastening of the mechanism of a tension the demanded moment.
4. Establish a krylchatka of the fan and a casing.

Models with the unique thick label

Adjustment of a tension of an auxiliary belt on the 4-cylinder engine
For adjustment of a tension of an auxiliary driving belt on the 4-cylinder engine rotate a nut of a regulator (1) while the index (2) will not be combined with the thick line (3).

PERFORMANCE ORDER
1. Rotating a regulator nut clockwise, combine the index of the mechanism of a tension with a thick label (see fig. Adjustment of a tension of an auxiliary belt on the 4-cylinder engine).
2. Tighten a bolt of fastening of the mechanism of a tension the demanded moment.
3. Establish a krylchatka of the fan and a casing.
