KRYOTEC ENGINE 151 11. Tighten the bearing cap bolts (1a) using a suitable angle tightening tool (1b) to the proper (Torque Specifications). 12. Verify that the main bearing journal diameters are within specification (Refer to 09 - Engine/ Specifications). 13. Check that the lubrication channels in the crankshaft are free of debris and clogging. 14. Measure the crankshaft main bearing journal diameters and verify that they are within specification (Refer to 09 - Engine/Specifications). 15. If the crankshaft main bearing journal diameters do not fall within the specifications, correct by refinishing the diameter of the journal up to an additional 0.127 mm. NOTE Do not attempt to refinish a crankshaft main bearing journal diameter more than 0.127 mm. Diameter adjustments greater than this endanger the structural strength of the crankshaft. If the adjustment required is greater than 0.127 mm, it is necessary to replace the crankshaft. The bearing shells used for adjustments greater than 0.127 mm are no longer available as a spare (although the relative number is still shown). 16. Measure the crankshaft rod bearing journal diameters and verify that they are within specification (Refer to 09 - Engine/Specifications). 17. If the crankshaft rod bearing journal diameters do not fall within the specifications, correct by refinishing the diameter of the journal up to an additional 0.127 mm. NOTE Do not attempt to refinish a crankshaft rod bearing journal diameter more than 0.127 mm. Diameter adjustments greater than this endanger the structural strength of the crankshaft. If the adjustment required is greater than 0.127 mm, it is necessary to replace the crankshaft. The bearing shells used for adjustments greater han 0.127 mm are no longer available as a spare (although the relative number is still shown). 18. Select main bearings to achieve the proper bearing clearance. Do not attempt perform any adaptation to the bearing shells. If you encounter any scratches or traces of engagement, replace the bearing shells with bearings from the same scheduled class. 19. Verify the bearing shells are clean and install them in the engine block crankshaft journals. 20. Install the crankshaft into place. 21. Apply the calibrated wire (Plastigage) across the surface of the bearing journals (1). 22. Check one journal at a time without moving the crankshaft. NOTE The main bearing caps have engraved notches (zero to four from the front of the engine) which define the mounting position.
