(4)   Install six screws securing vibration damper (3).  Torque conical screws to 70 to 80 foot- pounds (95 to 108 joules).  Torque hexagon head  capscrews  to  100  to  120  foot-pounds (136 to 163 joules). NOTE Crankshaft must be kept to front or rear limit of thrust clearance while wobble is being checked. CAUTION Do not pry against or strike damper. (4)   With   a   dial   gauge   mounted   to   gear   case cover     and     arm     resting     on     the     inner machined   surface   of   the   outer   member, check    vibration    damper    eccentricity    and wobble   at   points   (1)   and   (2)   as   show   in figure   13-32.      Wobble   must   not   exceed 0.009  inch  (0.23  mm)  per  inch  of  radius. Eccentricity   must   not   exceed   0.030   inch (0.76 mm). Figure 13-32.  Vibration Damper Wobble Check Points 13-19. ENGINE  FRONT  SUPPORT.    To  inspect  and replace  the  engine  front  support,  refer  to  figure  13-33, and proceed as follows: a.     Inspection.  Inspect the engine front support for signs   of   cracking   or   other   signs   of   damage. Replace if necessary, as follows: b. Removal. (1)   Refer  to  Chapter  2,  Section  IV  to  remove engine assembly. (2)   Remove screws (4), lockwashers (5), screws (6), and lockwashers (7). (3)   Remove screws (1), nuts (3), and lockwashers (2). c. Installation. (1)   Install  new  engine  front  support  screws  (1), lockwashers (2), and nuts (3). (2)   Replace engine assembly. (3)   Install lockwashers (7), screws (6), lockwashers (5), and screws (4). 13-20 OIL PAN ASSEMBLY.  To replace or repair the oil pan assembly, refer to figure 13-34, and proceed as follows: a. Removal. (1)   Drain oil in accordance with the Operator/Crew and Organizational Maintenance manual. (2)   Disconnect  temperature  sensor  (34,  figure 13-34) electrical connector.  Remove screw and   washer   securing   temperature   sensor cable  clamp,  then  move  and  secure  cable away from work area. (3)   Disconnect engine preheat hose coupling on radiator line and two couplings on preheater assembly,   then   remove   three   screws   and washers    securing    preheat    hose    support brackets    to    engine.        Move    and    secure preheat hoses away from work area. (4)   Remove     four     nuts     and     washers     from preheater assembly V-bolts, then move and secure preheater assembly away from work area. 13-64
