KRYOTEC ENGINE 153 33. Check that the axial clearance (1a) between the first and second ring (1b) and ring groove on the piston (1c) is within specification (Refer to 09 - Engine/ Specifications). 34. Check that the axial clearance between the scraper ring and its ring groove on the piston is within specification (Refer to 09 - Engine/Specifications). 35. Install the connecting rod caps (1b) to the connecting rods (1a) and tighten the bolts (1c) to the proper (Torque Specifications). 36. Verify that the diameter of the connecting rod big end (2) is within specification (Refer to 09 - Engine/ Specifications). 37. Reassemble the piston and connecting rod assemblies (Refer to 09 - Engine/Engine Block/ROD, Piston and Connecting/Disassembly and Assembly). 38. Inspect meshing teeth indications on the ring gear. If unusually worn, replace it. 39. Install the engine block on the 1871000000 maintenance stand. 40. Install the piston oil cooling jets in the engine block and tighten the screws to the proper (Torque Specifications). 41. Place the thrust bearings in their seats on the third main bearing journal. NOTE A new crankshaft is provided without bearing shells but is identified with journal and connecting rod dimensional class values in order to choose the bearing shells to assemble with "normal" journal and connecting rod bearing clearances. For the selection of main journal bearing shells the numeric code is printed on the crankshaft adjacent to the pins. Use only the codes related to the legend, all other codes present on the tone wheel must not be used. 42. The following is an example of a class identification of the main journals. • Crank pin identification (1): The number on the left refers to the first pin on the timing side. The "N" at the end is a code not significant for 4-cylinder engines. • Crank journal identification (2): the first number on the left refers to the first journal on the timing side. The "N" at the end is a code not significant for 4-cylinder engines. • Number blocks (if any), in groups of two digits (3), indicate the size (thousandth part) of the main
