Apply grease to the crankshaft journals.
Install:
- thrust semi-rings with grooves towards the cheeks of the crankshaft;
- crankshaft;
- caps of main bearings with an arrow towards the timing drive;
- old crankshaft main bearing cap bolts and tighten to specified torque.
Make sure the crankshaft rotates freely without binding.
Mount the indicator on the holder. Install a feeler gauge on the surface of the flywheel to the crankshaft.
Install the crankshaft on the support half ring by moving the shaft in the longitudinal direction towards the timing drive.
Calibrate the indicator to zero.
Install the crankshaft on the other support half ring by moving the shaft in the longitudinal direction towards the flywheel.
Check the axial movement of the crankshaft. Its value should be in the range from 0.10 to 0.30 mm.
Remove:
- old crankshaft main bearing cap bolts;
- liners assembled with crankshaft bearing caps.
Install the crankshaft.
