ENGINE DIAGNOSTIC TEST PROCEDURES Section 6 LINKAGE  ADJUSTMENT:    (With  Bellcrank)  Refer  to Figure   5a   for   Version   "I"   Linkage,   Figure   5b   for Version   "II"   Linkage   and   Figures   5b   and   5c   for Version "III" Linkage. IMPORTANT BALL JOINTS AND BELLCRANK SHAFT MUST ROTATE FREELY WITHOUT    BINDING    OR    STICKING. THE BALL JOINTS, BELLCRANK SHAFT, BORE AND BUSHING INSERTS  MUST  BE  FREE  OF  PAINT, GREASE,  OIL,  DIRT,  RUST,  OR  ANY OTHER FOREIGN MATERIAL.  CLEAN OR REPLACE PARTS IF NECESSARY. IMPORTANT MAKE THE FOLLOWING ADJUSTMENTS  AFTER  ENGINE  HAS BEEN RUN-IN AND INJECTION PUMP HAS BEEN SET. Version     "I"     Linkage     With     Standard     Regulation Governor (Figure 5a) 1. Postion   bellcrank   bracket   and   control   lever   as follows: a. Locate  bellcrank  shaft  centerline  15.82"  + 0.06"  from  front  finish  of  flywheel  housing (cranking    motor    pad).        Loosen    bracket mounting   hardware   for   this   adjustment   if required. b. Insert   3/16"   dia.      (1.875"   drill)   gauge   pin through   the   holes   (17,   Figure   5a)   of   the bellcrank bracket and control lever. 2. Assemble throttle lever on pump shaft.  Do NOT position lever in shaft groove. a. With    pump    shaft    in    low    idle    position, relocate the pump lever to gauge dimension shown in Figure 5a. Do  not  force  lever  into  over-travel  for  this positioning (Figure 5b). b. Spacer (23, Figure 5a) must be installed on the lever clamping bolt inside the lever slot to prevent lever breakage. Tighten clamping bolt to 55 Ibf-in.  (27, Figure 5a). 3. Install control rod assembly as follows: a. Hold  injection  pump  lever  against  low  idle stop   (do   not   force   pump   lever   into   over- travel position). WARNING Exposed threads above either control rod nut must not exceed 0.42 in.  (29, Figure 5a). b. Position the control rod ends so that the ball joint banjo face is aligned parallel with lever mounting face.  Then tighten the control rod nuts. c. Remove gauge pin. 4. Observe operation of linkage: a. Rotate  control  lever  counterclockwise  from low  idle  to  high  idle  and  past  high  idle  to max.  over-travel. b. Observe   max.   over-travel   at   the   injection pump lever.  The injection pump lever tang bottoms  in  the  lever  slot  when  max.    over- travel  is  reached.    DO  NOT  force  beyond this  point.    Pump  lever,  pump,  or  linkage components  will  be  damaged  if  excessive force is used. c. Release the control lever and let the springs return the linkage to low idle. d. Repeat   4a   thru   4c   two   more   times.      If linkage   has   been   properly   adjusted,   the linkage will return to low idle position.  The gauge     holes     will     be     aligned     and     the injection pump lever tang will be centered in the slot. IMPORTANT BEFORE    STARTING    THE    ENGINE, ENTER THE OPERATOR’S COMPARTMENT  AND  DEPRESS  THE THROTTLE  PEDAL  SEVERAL  TIMES TO   CHECK   FOR   SMOOTH   ACTION AND FULL RETURN OF THE THROTTLE LEVER & THROTTLE PEDAL. THIS MUST BE DONE ANYTIME COMPONENTS ARE REPLACED, REASSEMBLED OR ADJUSTED. CGES-240-4 Printed in United States of America Page 12
