2.2.2. Tension of a maple belt
Cars without gear lath on an arm
Because of increase in power generation by the generator of alternating current, check of a tension of a maple belt became more important.
The following indicators have to be defined when checking a tension of a maple belt when pressing on a belt by a thumb.
Maple belt up to 1000 mm long, maximum deviation and:
new maple a belt – about 2 mm
maple the belt which was in operation – about 5 mm
Maple the belt is longer, than 1000 mm, the maximum deviation and:
new maple a belt – about 10 mm
maple the belt which was in operation – about 15 mm
The given values are valid for cars of all modifications.
Adjustment
PERFORMANCE ORDER 
1) weaken bolts 
2) move the generator outside so that to receive the required maximum size of a deviation 
3) tighten fastening bolts 

Cars with the gear mechanism
PERFORMANCE ORDER 

1) weaken bolts In, With and a hinged bolt of a support (it is not shown in the drawing) 
Prevention
Bolts of fastening have to be rather weakened that the generator could move freely under the weight.

2) pull maple a belt rotating a tension gear wheel In by means of a wrench 
3) a free hand check the maximum deviation of a belt under pressure of a thumb for a new belt the deviation has to be 8 mm for an old belt the deviation has to be 4 mm 
4) twirl or turn off a tension gear wheel to achieve a necessary deviation 
5) after that, tighten fastening bolts till the next moments of an inhaling: the bolt inhaling moment In: 35 N. of m. the bolt inhaling moment With: 20 N. of m. support bolt inhaling moment: 35 N. of m.
