Fig.  9  Engine Lifting Sling 1.  Lifting sling ENGINE INSTALLATION Prior   to   installation   check   to   be   sure   that   all   lines, cables  and  parts  are  installed  on  the  engine  assembly  that were    connected    to    and    removed    with    the    engine.         If maintenance was performed, be sure all adjustments affected are  made  correctly.    If  any  components  of  the  engine  were removed   and   installed,   check   all   connections   and   related parts to insure the installations were accomplished correctly. In general, the installation of the engine is performed in the   reverse   order   of   the   removal.      When   positioning   the engine  in  the  chassis,  special  care  must  be  exercised  during installation  to  avoid  pinching  of  the  wiring  harness  between the engine and frame assembly. Lower  the  engine  to  align  the  transmission  main  drive gear  spline  with  the  clutch  driven  disc.     The  weight  of  the engine   assembly   must   be   supported   until   the   twelve   bolts securing  the  bell  housing  are  installed.     Connect  the  wiring harness,   lines   and   linkages   that   were   disconnected   during removal. Install  the  radiator  assembly  and  shroud  and  connect the   upper   and   lower   radiator   hoses   on   the   conventional chassis.
