ENGINE DIVISION SERVICE MANUAL TM 5-4210-230-14&P-1 ENGINE Fig. 139 Checking Camshaft End Play 1.  Camshaft gear 2.  Dial indicator 6. Wipe the backs of the cylinder block half of the bearings, making sure the dirt is removed.  Lubricate the block half of  the  bearings  on  both  sides  with  a  light  film  of  engine oil.  Place the bearing shell halves in position in the bore of the cylinder block, making sure the bearing shells are fully seated, the oil holes in the bearing shells line up with the oil holes in the cylinder block and the locking tangs on the   bearings   fit   into   the   recesses.   Follow   the   same procedure   and   place   the   bearing   shell   halves   in   the bearing caps.  Place a film of engine oil on both sides of the shell surfaces and Fig. 140 Aligning Timing Marks on Camshaft and Crank- shaft Gears 1. Camshaft gear 2. Timing marks 3. Crankshaft gear install  the  crankshaft,  aligning  itself  in  the  bearing  while, at  the  same  time,  aligning  the  timing  marks  of  both  the camshaft and crankshaft gears, Figure 140 NOTE:  If  crankshaft  gear  has  been  removed,  it  may  be installed with the crankshaft in the engine using SE-1900 Installer,  with  SE-1900-18  Adapter  and  thrust  bearing  to reduce friction, Figure 141. 7. Place the bearing caps and bearing lower halves over the crankshaft   journals.      Be   sure   the   bearing   caps   are properly installed with the number toward the left side of the crankcase and the arrow, pointing toward the front of the  engine.    Use  new  selflocking  bolts  for  installing  the bearing caps.  Finger tighten the bearing caps.  Using a soft  hammer,  tap  the  number  1,  2  and  4  bearing  caps until  the  rear  machined  faces  of  the  caps  are  flush  with the machined faces of the crankcase. Fig. 141 Installing Crankshaft Gear with SE-1900 Installer and SE-1900-18 Adapter 1.  Nut 3.  Thrust bearing 2.  Sleeve 4.  Gear Repeat  the  same  operation  for  bearing  cap  number  5  only aligning  the  front  face  of  the  cap  with  the  crankcase.  The number 3 bearing rear thrust flanges must be flush with each other.  Aligning  caps  in  this  manner  will  assure  proper  cap location.  Check this alignment at both sides (left and right) of the bearing cap.  Torque the bolts to specified torque using a tension wrench.  See "Torque Chart."
