TM 10-3930-671-24 3. Apply a light coat of cement (national oil seal or EC-847) to the butting ends of the crankshaft oil seal   halves.      Allow   to   become   tacky   before assembling.    Lightly  coat  the  crankshaft  contact edge of the seal with graphite grease to prevent damage prior to use. 4. Install crankshaft. 5. Apply  a  light  coating  of  RTV  gasket  material  to surface  "B"  and  graphite  grease  to  the  oil  seal lip.  Carefully install the combination rear bearing cap and filler block on to the dowels.  Insert the capscrews and torque to 150-162 N•m (110-120 Lb. Ft.) 6. After the rear cap is in place and torqued, inject RTV  into  each  side  seal  slot  "D"  as  shown  in illustration.    Force  the  RTV  into  the  channels until   a   steady   flow    comes    out    the    corner chamfers. NOTE 0il leakage will occur if any voids are left along these slots. 7. Dip   the   curing   insert   in   clean   water.      Install curing  insert  until  approximately  5/8"  protrudes from slot.  Cut off flush with pan rail.  This insert insures complete cure of the RTV. 8. Prior to installing oil pan,  apply  a  small  bead  of RTV  material  to  the  rear  bearing  cap  and  filler block as shown. OIL PUMP The  oil  pump  is  assembled  to  the  front  of  the  cylinder block and front main bearing cap and is held in place by capscrews. The  pump  is  driven  by  a  hardened  key  mounted  in  the crankshaft. F-182
