(7)  Check  end  play  of  the  crankshaft  using  a  dial indicator. Tap   crankshaft   with   a   soft-headed   hammer in  one  direction  to  take  up  slack  or  end  play.  After dial   indicator   is   set   in   place,   force   crankshaft   with   a pry  bar  in  opposite  direction  to  obtain  end  play  read- ing.  The  end  play  is  0.007  to  0.013  inch.  The  end play  is  controlled  by  thrust  flanges  at  the  center  main bearing.  If  end  play  is  not  within  the  allowable  range, replace   thrust   flanges. Thrust  flanges  are  available in  standard  thickness  (0.  126  to  0.  127  inch)  and  0.005, 0.010,  and  0.  015  inch  oversize. (8)   Install   piston   and   connecting   rod   assembly. (para  14-83.) (9)   Install   crankshaft   gear   and   timing   gear housing.   (para   14-75.) (10)  Install  flywheel  housing.  (para  14-70.) (11)   Install   oil   pump   and   oil   pan.   (para   14-67.) (12)   Install   crankshaft   pulley   and   vibration dampener.   (para   14-63.) (13)   Refer   to   Operator   and   Organizational Maintenance  Manual  and  install  electric  starter, winterization  kits  (if  installed),  manifolds,  turbo- charger,   radiator   and   housing. c.   Camshaft   beari ng    installation. (1)  Position  new  bearing  so  that  oil  hole  in bearing  lines  up  with  oil  hole  in  cylinder  block. (2)   Front   bearing   must   be   installed   so   that   bear- ing  end  is  flush  with  or  below  front  side  of  cylinder block. (3)   The   rear   and   intermediate   bearings   are   alike. The  rear  bearing  should  be  installed  with  the  bearing end  flush  with  the  front  side  of  the  cylinder  block  bear- ing  bore. NOTE When  a  new  camshaft  rear  bearing  is  installed in   place,   the   old   rear   bearing   will   remain   partly in  the  cylinder  block. Use  a  punch  and  collapse the   old   bearing,   preferably   at   the   seam,   and remove  the  old  bearing  with  pliers. (4)  Install  remaining  bearings. (5)  Install  cylinder  sleeve.  (Refer  to  step  a. above.) (6)  Install  cylinder  head  and  valve  operating mechanism. (para   14-79.) (7)   Install   crankshaft.   (Refer   to   step   b.   above.) (8)   Install   piston   and   connecting   rod   assemblies. (para   14-83.) (9)  Install  timing  gears  and  housing.  (para 14-75.) (10)   Install   flywheel   and   housing.   (para   14-70.) (11)  Install  oil  pump  and  oil  pan.  (para  14-65.) (12)   Refer   to   Operator   and   Organizational Maintenance   Manual   and   install   valve   cover,   manifolds. turbocharger,   radiator,   electric   starter   and   housing. d.   Oil   Pressure   Regulating  Valve   Installation   and Adjustment. (1)  Thoroughly  clean  valve  bore  in  cylinder block,   lubricate   valve   piston   with   clean   oil   and   install the   regulating   valve   components   in   the   reverse   order of   removal. (2)   Turn   valve   adjusting   screw   into   cylinder block   the   same   number   of   turns   required   for   removal. (3)   With   the   engine   re-installed   in   the   generator set,  start  the  engine  and  allow  it  to  reach  normal operating    temperature. Adjust  oil  pressure  regula- tion  screw  to  obtain  oil  pressure  of  45  psi.  No  further adjustment   should   be   necessary. e.   Oil   Pressure   R egulating   Valve   Removal. Remove  oil  pressure  regulating  valve  in  the  order  of sequence   numbers   (items   31-36,   figure   14-41, sheet  3). (1)   Thoroughly   clean   the   area   around   the   cylin- der  block  where  the  pressure  regulating  valve  is  lo- cated. (2)  Loosen  jam  nut. (3)   Remove   regulating   valve   screw, ber   of   turns   required   for   removal. (4)   Withdraw   the   spacer,   spring   and noting  num- piston. f.   Oil   Pressure   Regulating   Valve   Cleaning Inspection   and   Repair. (1)  Wash  valve  parts  in  cleaning  solvent  and  in- spect   carefully   for   wear   or   damage. (2)  Inspect  the  valve  seat  in  the  cylinder  block and   clean   if   necessary. (3)  Replace  any  necessary  parts. 14-96  Change  8
