KRYOTEC ENGINE 154 journals: the first two numbers on the left refer to the first journal on the timing side. • For the identification of the class of journals you should refer to the numerical code of reference (2). • In the case of the example, numbers 11111N indicate that all five pins are Class A (red). 43. Another method of identifying the class of the pins is to read the reference (3). In the case of the number 94 (the first on the left) corresponds to the dimensional value of 52.994 of the first journal that identifies the Class A (red color). The same method should be applied to other groups of two figures (97 - 95 - 95 - 94). BEARING CLASS • Crankshaft journal class A (normal), 52.99453.000 mm, RED, code 1 (94 00) * • Crankshaft journal class B (normal), 52.98852.994 mm, BLUE, code 2 (88 94) * • Crankshaft journal class C (normal), 52.98252.988 mm, YELLOW, code 3 (82 88) * • Crankshaft journal class D (refinished 0.127 mm), 52.867-52.873 mm, BROWN, code 6 (67 73) * • Crankshaft journal class E (refinished 0.127 mm), 52.861-52.867 mm, GREEN, code 7 (61 67) * • Crankshaft journal class F (refinished 0.127 mm), 52.855-52.861 mm, BLACK, code 8 (55 61) * (*): Last two numbers (part thousandth) is the size of the main journals. NOTE When using a crankshaft which has been refinished to the maximum value of 0.127 mm by the operation of grinding and lapping, the class must be chosen by means of dimensional measurement of the pin diameter as previously described. The clearance between journal and bearing shell, obtained by the selection method indicated above, must be within the following values: Minimum: 0.011 mm - Maximum: 0.071 mm. This value may be measured, as a final check, using the calibrated wire (Plastic Gauge). 44. Install the lower bearing shells in the engine block. 45. Install the crankshaft onto the bearing shells in the engine block. NOTE The main bearing caps have engraved notches (zero to four from the front of the engine) which define the mounting position. 46. Install the upper bearing shells into the bearing caps and install the bearing caps. 47. Tighten the bearing cap bolts using a suitable angle tightening tool to the proper (Torque Specifications). 48. Install the 1860815000 crankshaft rotation tool. 49. Rotate the crankshaft with the tool until the affected cylinder is at BDC. NOTE: Position the rod and piston in the engine block so that the discharge on the skirt of the piston is aligned with the oil jet mounted on the engine block. Select the appropriate bearing shell class based on the following measurement procedure. 50. Install the rod and piston (1a) complete with bearing shell using a ring compressor (1b). 51. Repeat the proceeding steps for installation of the remaining rod and piston assemblies into the engine block.
