SERVICE MANUAL CONNECTING RODS, PISTONS, RINGS & SLEEVES Section 5 REMOVAL Remove    the    Connecting    Rods    and    Pistons    as follows: 1. Remove    the    cylinder    head    as    described    in Section 3. 2. Remove the drain plug and drain the crankcase oil pan. 3. Remove the oil pan and gasket. NOTE:      It   is   recommended   to   check   crankshaft bearing    bolt    torque    on    the    main    bearing    and connecting rod bolts anytime the oil pan is removed. 4. Check the main bearing and connecting rod bolt torques (prior to teardown) as follows: a. Using a direct reading torque wrench (Not a "CLICKER" type) place the socket over the bolt head and gently pull the wrench  in  the tightening direction to remove slack. 1. Mark the bolt and rod with the marks in alignment. 2. For    mains,    mark    the    cap    and    the socket. b. Loosen  bolts  1/4  turn.    Tighten  with  a  slow steady  motion  and  read  the  torque  at  the moment the marks are once again aligned. c. On the main bearing bolts if torque is found to be below 155 N•m (115 lbf-ft), and cap is not  to  be  removed,    back  off  1/4  turn  and retorque to 155 N•m (115 Ibf-ft).  Those at 155 N•m (115 Ibf-ft) or higher should be left with marks aligned. d. For  connecting  rod  bolts  if  the  torque  of both bolts is 175 N•m (1 30 Ibf-ft) or higher, and rod is not to be removed, they may be left with the marks aligned. e. If the torque of either bolt is found to be less than 150 N•m (110 Ibf-ft), the rod should be removed and inspected. f. If the torque of both connecting rod bolts is found  to  be  at  least  150  N•m  (110  Ibf-ft), but  either  or  both  less  than  175  N•m  (130 Ibf-ft), the cap should be removed and the bearing inspected. If bearing distress is noted or bearings are not a tight fit in rod and cap, new inserts should be used and the cap reinstalled.    If  no  bearing  distress  is  noted,  reinstall  the bearings and cap. NOTE: Before proceeding with piston and connecting  rod  removal,  inspect  the  sleeves  at  the upper  end  of  the  ring  travel  for  the  presence  of  a ridge.  This ridge must be removed with a fine emery cloth   and   a   carbon   scraper   before   the   piston   is removed.    This  prevents  damage  to  the  piston  ring lands  during  removal  and  also  prevents  damage  to new  piston  rings  when  installing  the  piston.    When removing a piston from the  crankcase,  do  not  allow the    piston    skirt    to    strike    the    crankcase    or    the connecting rod to strike the piston sleeve, as severe damage to the sleeve could result. 5. Remove  the  connecting  rod  bolts  from  the  rod caps  and  remove  the  caps  and  bearing  inserts from  the  rod  ends.    Keep  in  order  and  observe markings to prevent mismatching. 6. Push the connecting rod and piston to the top of the cylinder and remove them from the top of the crankcase with EXTREME CARE. 7.    Crank  the  engine  by  hand  and  remove  all  of  the remaining   pistons   as   outlined.      Be   sure   to replace   each   bearing   cap   on   its   respective connecting  rod  after  removal  of  the  piston  from the engine. NOTE:    It  is  advisable  to  wrap  an  oil-soaked  cloth around     the     crankshaft     connecting     rod     bearing journals  to  keep  them  as  clean  as  possible.    Wrap the  piston  and  connecting  rod  assemblies  in  clean cloth also to protect them until installation.
