TM 9-2815-225-34&P 3-63.  FUEL PUMP TESTING AND CALIBRATION (Contd) LOCATION/ITEM ACTION REMARKS i.  Throttle Lever Travel Adjustment 72. Slow switch (23) Depress until 500 rpm is indicated on tachometer (7). 73. Level and angle indicator Position on fuel pump main Use level and angle indicator (101) housing (51). (3375855) (101). NOTE Do  not  adjust  rear  throttle  stop  from  the  position  it  was  adjusted  to  under  THROTTLE LEAKAGE ADJUSTMENT.  The rear throttle stopscrew has already been set to provide the proper   deceleration   time   for   the   engine,   and   any   change   at   this   point   will   require recalibration of throttle leakage. 74. Throttle lever (48) a.  Using level and angle indicator The throttle lever (48) may be (101), set the idle position repositioned on the throttle centerline of throttle lever (48) at shaft (50) as required to attain 55 from the vertical on 55. the centerline of throttle shaft (50). b.  Move to full-throttle position. Check centerline travel of throttle At this position, the centerline lever (48).  Centerline travel from of the throttle lever must be idle position to full-throttle 27 as shown on level position must be 27.  If throttle and angle indicator (101). lever (48) travel is not correct, loosen jamnut (102) and adjust front throttle stopscrew (103) to attain 27 travel, then lock setting with jamnut (102). c.  Checking and adjusting throttle The throttle lever travel template lever (48) travel using tool 3375355, has two sets of matched holes for throttle lever travel template (116). lever alinement that may be used. The first and third holes, moving clockwise from MAX to IDLE on the template, will set lever travel for 27-29 movement.  The second and fourth holes, moving clockwise from MAX to IDLE will also set lever travel for 27-29 movement.  Either set of holes may be used, but do not use the first and last hole in combination or the second and third holes; otherwise an erroneous reading will result.  See figure B. d.  Position template (116) on fuel Move the throttle lever to idle pump housing as shown in figure A. position, and line up the hole on the throttle shaft lever with the idle hole on the template.  The throttle shaft lever may be repositioned on the throttle shaft as required to line up the holes. e.  Move throttle lever (48) to full Line up the hole on the throttle throttle position. lever (48) with the appropriate MAX hole on the template.  If throttle lever travel is not correct, loosen the jamnut (102) and adjust the front throttle stopscrew (103) to line up the holes. 3-498
