(2) Timing Method 1. This is a means for calcu- lating the correct button thickness before the pump is installed. It requires the port closing dimensions and button thickness from the pump being replaced. Sub- stitute the dimensions for those in the formula below and calculate the new button thickness. Determine the button code letter from table 7-1. Example Formula: Port closing dimension of old pump (removed from engine) . . . . . . . . . . 1.093 TM 5-6115-584-34 NAVFAC P-8-622-34 TO-35C2-3-456-2 TM-0568C-34 NOTE Always use button thickness closest to this dimension. Install the correct button in pump (figure 7-33) and install pump following the instructions under injec- tion pump installation above. (3) Timing Method 2. Flowing the Pump. (a) Install a Number 12 or M timing button in injection pump and install pump on engine, following instructions under injection pump installation above. Button thickness of old pump . . . . . . . +0.119 1.212 Port closing dimension of new pump . . . . -1.089 When removing tappets which contain timing Button thickness of new pump . . . . . . . 0.123 buttons, do not allow the portion of the injec- tion pump which has the face gear to be lifted Use button M from its position.
