If no TDC mark on flywheel, How will you check pump timing?

IN MAIN ENGINE

  • Make a marking between cross head and guide Shoe while they are before TDC and also mark at the flywheel.  
  • Turn the crank shaft in the same direction until the crosshead and guide shoe are at the previous mark (coincide) 
  • Make the second marking on the fly wheel. We got two marks on the flywheel mid point between the two points is TDC.  
  • I will divide 360C around the flywheel.

  IN AUX ENGINE
  •  Remove the fuel valve  
  • Insert the rod onto the piston (mark on rod and flywheel)  
  • Turn crank until the rod previous mark  
  • Make the second marking on the fly wheel  
  • Mid point between the two points is TDC
