THE GENERAL DATA

Cars without gear рейки on an arm

Because of increase in development of the electric power the alternating current generator, tension check клинового a belt became more important.

Following indicators should be defined at tension check клинового a belt at pressing on a belt by a thumb.

Klinovoj belt in length to 1000 mm, the maximum deviation and:

New клиновой a belt – about 2 mm

клиновой a belt which was in operation – about 5 mm

The klinovoj belt is longer, than 1000 mm, the maximum deviation and:

New клиновой a belt – about 10 mm

клиновой a belt which was in operation – about 15 mm

The resulted values are valid for cars of all updatings.

Adjustment
PERFORMANCE ORDER
1) ослабьте bolts
2) move the generator outside so that to receive the demanded maximum size of a deviation
3) tighten fastening bolts

Cars with the gear mechanism
PERFORMANCE ORDER
1) ослабьте bolts In, With and шарнирный a support bolt (it is not shown in drawing)
The prevention

Fastening bolts should be weakened enough, that the generator could move freely under the weight.
2) pull клиновой a belt rotating a tension gear wheel In by means of a wrench
3) a free hand check up the maximum deviation of a belt under the pressure of a thumb
For a new belt the deviation should be 8 mm
For an old belt the deviation should be 4 mm
4) twirl or turn off a tension gear wheel to achieve a necessary deviation
5) after that, tighten bolts of fastening till following moments of an inhaling:
The moment of an inhaling of a bolt In: 35 Н.м.
The moment of an inhaling of a bolt With: 20 Н.м.
The moment of an inhaling of a bolt of a support: 35 Н.м.
