3161 GOVERNOR
TESTING AND ADJUSTING 7.
Use a soft faced hammer and hit the outer pump drive shaft so the pump snaps (moves suddenly) in place.
8.
Install the four bolts and tighten them to a torque of 10 N-m (90 lb. in.).
9.
Make sure the drive shaft turns freely after the bolts have been tightened.
GOVERNOR PREPARATION
OIL PUMP INSTALLATION 7. Roll pin. 8. Reference hole for roll pin. 9. Plug. 10. Location hole for roll pin to change pump rotation. 11. Strap to hold plug in position when pump housing is removed. To change the direction of pump rotation do the following steps:
The pump housing holds plug (9) in position. There is spring force on the plug. To prevent injury, mechanically hold plug (9) in the governor housing when the pump housing is removed. 1.
Remove the four bolts that hold the pump in place.
2.
Use two screwdrivers to lift the pump housing and O-ring seal from the governor.
3.
Pull roll pin (7) from the pump housing flange and install it in location hole (10) in the opposite side of the flange.
4.
Turn the pump housing and make an alignment of roll pin (7) and reference hole (8) in the governor base.
5.
Put a new seal on the oil pump housing. Put clean engine oil on the seal and install the assembly part way into the bore in the base of the governor.
6.
Make sure the external pump drive spline is in correct alignment with the internal coupling spline. If the splines are not in alignment, damage to the governor will be the result when the pump housing bolts are installed and tightened.
INSTALL COVER ON GOVERNOR 1. Location for bolt. 2. Cover. Because of the close clearance between the fuel control linkage cover and governor, the upper left hand bolt must be installed at location (1) before cover (2) is put on the terminal shaft and the governor is bolted to the drive adapter housing. The other bolts can be put in place after the governor is in position on the engine. Put clean engine oil on the lip of the seal and install cover over the governor terminal shaft.
CONTROL LEVERS 3. Lever. 4. Lever. 181
