Remove timing fixture plate (A) from housing. Put housing of injection pumps and governor into position, and install bolts. 8. Remove caps from injection pumps. Put lines into position, and tighten nuts (2) to 30 5 lb.ft. (4,1 0,7 mkg).9. Install the oil supply line and the oil drain line for the turbocharger.10. Install the crankcase breather pipe (3). Connect the control linkage (1) to governor. Install engine side cover.Separation Of Governor From Fuel Injection Pump Housing
start by: a) remove fuel injection pump housing and governor as a unit 1. Remove the cover (1).2. Remove the screw (2) for the rack stop collar.3. Remove rack stop collar (3).4. Remove the bolts (4) that hold the governor to the housing of injection pumps. 5. Remove the governor housing (5).6. Remove the governor spring and seat assembly from the guide in housing (5).7.

Push the cylinder and weight assemblies onto the location dowels. 3. Install the three bolts (4) and lock.4. Install the washer type spring (5) on bolt (6).5. Put the seat assembly and governor spring on guide in governor housing. The washer type spring (5) should be installed so the inside diameter of spring will be against the guide in governor housing (7).6. Put the governor housing (7) in position on housing of injection pumps, and install the bolts. 7. Install the rack stop collar (8) on bolt (6).8. Put the idle screw cover (10) in position on the governor housing so the dowel (11) in housing is engaged with slot (12) in the rack stop collar.9. Install the bolts that fasten the idle screw cover to the governor housing.end by: a) install fuel injection pump housing and governor as a unitb) make an adjustment to the rack and governor (See FUEL RACK SETTING AND GOVERNOR ADJUSTMENTS in TESTING AND ADJUSTING)
