SERVICE MANUAL CALIBRATION Section 5 NOTE:    Balance  should  be  maintained  to  as   close   a tolerance as is reasonably possible to prevent readjustment in later tests. Fuel Delivery at Lo-Idle Check 23. This   is   an   operating   test   to   assure   that   the injection  pump  provides  the  proper  quantity  of fuel at lo-idle.  Test and adjustment are made as follows: a. Operate  test  stand  at  specified  RPM  with control  lever  in  lo-idle  position  (fully  back) for 1000 strokes. b. Record   fuel   delivery   from   elements   and compare   results   with   specifications   given on CALIBRATION CHART. c. Check  balanced  delivery  between  pumping elements    and    compare    imbalance    with specifications given on CALIBRATION CHART. d. Adjust   fuel   delivery   and   imbalance   (see Test 21). Check Fuel Delivery at Torque Check Speed 24. This is an operating test to assure proper pump and   governor   operation.      Perform   the   test   as follows: a. Operate     stand     at     specified     RPM     with control    lever    locked    in    full    load    (fully forward) position for 1000 strokes. b. Record   fuel   delivery   from   elements   and check for balanced delivery between pumping elements and compare with specifications given on CALIBRATION CHART.    If  not  within  specifications  repeat Steps 20, 21 and 22. Check Aneroid Controlled Power and Fuel (Cutback)     25. Check with boost line disconnected.  If not within specifications proceed as follows: a. Remove cap from rear of aneroid. Figure 10.  Adjusting Aneroid Cutback 1. KDEP 1048 2. Aneroid b. Using  KDEP  1048  (Figure  10)  turn  socket  head screw  clockwise  to  increase  power  and  fuel  or counterclockwise to decrease power and fuel. Check Low Speed Power and Fuel (Aneroid Controlled) 26. This adjustment is for correct spring preload.   If not    within    specifications    on    calibration    chart (Step 14) adjust as follows: a. Remove  recessed  hex  head  plug  from  top of aneroid.  Use a screwdriver as a lever for turning the star wheel. b. If   power   or   fuel   are   below   specifications engage  screwdriver  blade  with  star  wheel pushing  screwdriver  towards  engine.    This reduces   spring   preload,   increasing   power and fuel. c. If power or fuel are above specifications pull engaged   screwdriver   away   from   engine, increasing    spring    preload    and    reducing power and fuel. After adjustments are made make sure Steps 21 and 25 are still correct. CGES-375 Printed in United States of America Page 7
