Checking the axial free motion of the crankshaft

NOTE The test is conducted with a liner installed and removed the flywheel. Crankshaft freely installed in the engine block.

Measure the axial clearance.

Fig. 2.207. Measurement of the axial clearance of the crankshaft

Set the indicator type guard in front of the front contact surface of the crankshaft (Fig. 2.207). Measure the axial clearance by moving the crankshaft. Permissible axial clearance: from 0,100 to 0,202 mm. Checking roundness of crankshaft

NOTE Crankshaft removed and placed freely in the cylinder block

Disconnect the base of the cylinder block. 12 Loosen the mounting bolts M6. 10 Loosen the mounting bolts M8. Install LED watch type opposite the central neck.

Fig. 2.208. Measurement of

roundness of the clearance of the crankshaft

Measure the roundness turning the crankshaft (Fig. 2.208). Allowable roundness: 0,03 mm. Apply (gray) kremnievorganichesky sealant.

NOTE After drawing kremnievorganicheskogo sealant (gray) base of the cylinder block should be installed within 10 minutes.
