SERVICE MANUAL TIMING, GEAR TRAIN & FRONT COVER Section 7 6. If the injection pump gear was removed install it as  follows:  (For  engines  equipped  with  Robert Bosch Model MW Fuel Injection pump) a. Be sure that engine crankshaft timing is set at  specified  static  timing  prior  to  going  any further. b. Using drive gear bolts and washers, loosely  install’  injection  pump  drive  gear  to injection   pump   meshing   it   with   the   idler gear (1, Fig.  27b).  Make sure drive gear is positioned   in   gear   slots   (Fig.      27c)   so   it allows for adjustment. c. Align timing pointer (1, Fig.  27a) with timing mark   (2,   Fig.      27a)   by   rotating   injection pump clockwise (as viewed from drive gear end). NOTE:    For   engines   equipped   with   Robert   Bosch Model MW Fuel Injection Pump the timing pointer is located on the injection pump mounting adapter and the timing mark is located on the drive hub. d. Holding the pump shaft with a socket wrench (3, Fig.  27b) torque drive gear bolts to 47 N•m (35 Ibf-ft). e. Rotate  engine  crankshaft  counterclockwise  900 then  rotate  clockwise  until  pump  timing  pointer and timing mark align. f. Observe   engine   to   injection   pump   timing   on crankshaft    pulley    (Fig.        27d).        Refer    to specifications (introduction) for correct alignment (or see Chart 1,  Section 11, Page 16). 7. If   the   tachometer   drive   gear   was   removed, proceed   as   follows:   (UTDS*   Model   100   Fuel Injection Pump) a. Insert the gear onto the dowel. b. Slip the spacers over the mounting studs or bolts. c. Place the thrust plate over the studs and gear. d. Install  and  tighten  nuts  to   27   N•m   (20   Ibf-ft) torque. 8. Using  a  new  gasket,  install  the  crankcase  front cover. -Full Front Cover- (See Fig.  5) a. For front covers with "ears" install the gasket as shown   in   Fig.      28.      DO   NOT   remove   ears (shaded areas). Figure 28.  - Front Cover Gasket (Rear View) - Earless Front Cover - (See Fig.  6) b. When   the   gasket   (Fig.      28)   is   used   on "earless"  front  cover  applications,    install the gasket and front cover then remove the ears (shaded areas on Fig.  28). NOTE:            If    the    "EARS"    are    removed    prior    to installation, gasket misalignment may result: NOTE:  Improper front cover installation will result in cover distortion or loose engine mounting bolts. *United Technologies Diesel Systems (formerly AMBAC) CGES-185-3 PRINTED IN UNITED STATES OF AMERICA Page 15
