TM 5-3895-382-24 Start By: a. Remove the water pump.  Refer to Disassembly and Assembly, "Water Pump - Remove". b. Remove the fuel injection lines.  Refer to Disassembly and  Assembly,  "Fuel  Injection  Lines  -  Remove  and Install". c. Disconnect any wires to fuel injection pump. NOTE: For a complete description of Type 1 and Type 2 Engines, refer to the Disassembly and Assembly, "Engine Design" topic. NOTICE Keep all parts clean from contaminants. Contaminants    may    cause    rapid    wear    and    shortened component life. NOTICE Care  must  be  taken  to  ensure  that  fluids  are  contained during  performance  of  inspection,  maintenance,  testing, adjusting and repair of the product.  Be prepared to collect the   fluid   with   suitable   containers   before   opening   any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose  of  all  fluids  according  to  local  regulations  and mandates. 1. Ensure that the number 1 cylinder is at the top center position   on   the   compression   stroke.      Refer   to   the Testing and Adjusting, "Fuel System" topic for additional information. Illustration 37 Typical example Illustration 38 Typical example NOTE: Do  not  remove  hub  nut  (4)  from  the  shaft  of  the fuel injection pump.  The hub of the fuel injection pump is installed in the correct position from the factory  in  order  to  ensure  proper  timing.    If  hub nut  (4)  is  removed  and  the  hub  is  removed,  the hub  will  need  to  be  accurately  installed  on  the shaft    of    the    fuel    injection    pump.        Special equipment  is  available  at  your  Caterpillar  Dealer for this procedure. NOTE: Do not release torx screws (5).  If the torx screws are  released  and  the  timing  plate  is  moved,  the timing  position  that  is  set  at  the  factory  will  be lost.  If the torx screws are released, the number 1 cylinder must be set to the top center position on the  compression  stroke  before  the  torx  screws are tightened. 2. Slowly rotate the crankshaft until hole (6) in the timing gear and hole (7) in the hub are in alignment with hole (8) in the fuel injection pump body. NOTE: The  location  of  Tool  (A)  for  Bosch  fuel  injection pumps  will  be  located  toward  the  top  of  the  fuel injection pump.  The location of Tool (A) for Lucas and    Stanadyne    fuel    injection    pumps    will    be located  toward  the  bottom  of  the  fuel  injection pump. 3. Install Tool (A) through hole (6) in the timing gear and hole (7) in the hub.  Push Tool (A) into position in hole (8) in the fuel injection pump body.  If Tool (A) can be fully  seated,  the  fuel  injection  pump  timing  is  correct. No  resistance  should  be  felt  when  the  timing  pin  is inserted into hole (8) of the fuel injection pump body. 7-18
