F2B ENGINE 67 T RAKKER E URO 4/5 PRINT603.93. 641 Figure 84 Figure 85 Place a piece of calibrated wire on the journal of the crankshaft (2), parallel to the longitudinal axis; install the lower crankcase (1), by hoist and appropriate hooks. 49022 - Lubricate inside screws (1) con UTDM oil, and tighten 47578 them by torque wrench to 140 Nm torque, thus with 60є angle closing, following the diagram in Figure 86.
Figure 86 FRONT SIDE Diagram showing the tightening order of the screws fixing the lower crankcase to the block 44898 Figure 87 Checking crankshaft end float Figure 88 - Remove the lower crankcase The clearance between the main bearings and the journals is obtained by comparing the calibrated wirelength (2) at the maximum deflection point, with the calibrated scale on the coating (1) containing the calibrated wire (1). Numbers shown on the scale specify the clearance in coupling millimeters. If the clearance obtained is different from the clearance required, replace the half-bearings and repeat this check.
47579 47588 End float is checked by placing a magnetic dial gauge (1) on thecrankshaft (2), as shown in the figure. If thevalue obtained is higher than specified, replace the rear thrust half-bearings and repeat this check. Print 603.93.641 Base q November 2006
