Test is carried out with the established loose leaves and the removed flywheel. The cranked shaft is freely established in the block of cylinders.
|
Measure an axial gap.
Establish the indicator of hour type opposite to a forward contact surface of a cranked shaft.
Measure an axial gap moving a cranked shaft.
Admissible axial gap: from 0,100 to 0,202 mm.
Check of ovality of a cranked shaft
Disconnect the basis of the block of cylinders.
|
NOTE
The cranked shaft is removed and placed freely in the block of cylinders
|
Unscrew 12 bolts of fastening of M6.
Unscrew 10 bolts of fastening of M8.
Establish the indicator of hour type opposite to the central neck.
Measure ovality rotating a cranked shaft.
Admissible ovality: 0,03 mm.
Put (gray) kremniyevorganichesky hermetic.
|
NOTE
After drawing of kremniyevorganichesky hermetic (gray) the basis of the block of cylinders should be established within 10 minutes.
