TM 5-3895-382-24 8. Install   the   fuel   transfer   pump   on   the   cylinder   block. Clean  the  threads  of  the  bolts  or  the  studs  and  nuts. Apply 4C-4030 Thread Lock Compound to the first three threads  of  the  bolts  or  Suds.    Refer  to  Specifications, "Fuel  Transfer  Pump"  for  the  torque  for  tightening  the bolts or the nuts and studs. Setting The Top Center Compression Position For No.  1 Piston Set The Top Center Position By Temporary Marks On Type 1 Engines and 9RM Engines NOTE: For a complete description of Type 1 and Type 2 engines,  refer  to  the  Systems  Operation,  Testing and Adjusting Module, "Engine Design" for more information. Illustration 28 Setting top center compression position. (1) Temporary pointer (2) Dial indicator 1. Fasten a temporary pointer (1) to the cover of the timing case.  Put the tip of the pointer close to the outer edge of the crankshaft pulley or the damper. 2. Rotate the crankshaft in a clockwise direction when you face the front of the engine.  Rotate the crankshaft until the pushrod for the inlet valve of the rear cylinder begins to lift the rocker lever. 3. Remove the rocker cover. 4. Remove the spring clip and the spacer from the front of the rocker shaft.  Release the fasteners of the two front pedestals of the rocker shaft.  Remove the front rocker lever.    Tighten  the  fasteners  of  the  pedestals  on  the rocker shaft. 5. Remove the valve springs from the front valve. NOTE: Place a suitable collar near the top of the valve in order to hold the valve if the crankshaft is rotated too far.  Use care in rotating the crankshaft.  The number 1 inlet valve will be held in position on top of  the  piston.    If  the  crankshaft  is  not  properly positioned,  the  valve  may  fall  from  the  cylinder head. 6. Allow the valve to be held by the top of the piston. 7. Fasten  a  dial  indicator  (2)  to  the  cylinder  head.    The contact of the dial indicator must be in contact with the top of the valve stem.  The dial indicator must indicate a reading  which  is  greater  than  zero.    Slowly  rotate  the crankshaft  in  a  clockwise  direction  until  the  clockwise movement of the dial indicator pointer stops. 8. Make   a   suitable   temporary   mark   on   the   crankshaft pulley or the damper in order to align the mark with the temporary pointer.  Continue to rotate the crankshaft in a   clockwise   direction   until   the   dial   indicator   pointer barely begins to move in a counterclockwise direction. Make   another   temporary   mark   on   the   pulley   or   the damper  in  order  to  align  the  mark  with  the  temporary pointer.  Mark the center point between the two marks on  the  pulley  or  the  damper.    Remove  the  other  two marks. 9. Rotate the crankshaft by approximately 45 degrees in a counterclockwise  direction  when  you  face  the  engine from the front.  Then rotate the crankshaft in a clockwise direction until the mark on the pulley or the damper is aligned with the pointer.  Number 1 piston is now at the top center on the compression stroke. Set The Top Center Position By Reverse Pin Timing On Type 2 Engines and 7BJ Engines NOTE: For a complete description of Type 1 and Type 2 engines,  refer  to  the  Systems  Operation,  Testing and Adjusting Module, "Engine Design" for more information. Table 3 Tools Needed Timing Pin 150-3993 (Lucas and Stanadyne) 1 The timing position that was set at the factory is used to set the engine  at  the  top  center  on  the  number  1  cylinder  of  the compression stroke before the fuel injection pump is removed. 6-52
