TESTING AND ADJUSTING housing with bracket assembly (10) as follows: Use a top cover bolt with three washers (as spacers under the bolt head) on it and put the bolt through the fixed diameter hole in the bracket. Fasten the bracket to the left side of the housing in the second threaded hole from the front. Put the dial indicator in the adjustable hole in the bracket assembly and position it so the indicator contact point (11) rests on the bolt head (12) of the torque control lever.

Check to make sure the cam follower is on the base circle of the governor torque rise cam. See Systems Operation section for a description of the base circle.
9.
Move dial indicator (9) until it reads zero and fasten it in place.
10.
Turn the synchronizing pin out of the engine front drive housing a minimum of half-way. As the synchronizing pin is backed out, dial indicator (5) will follow the fuel control linkage movement until the fuel control linkage stop lever contacts the fuel setting screw. Dial indicator (5) now shows the torque rise fuel setting. Make sure the torque rise fuel setting is correct. If not, an adjustment is necessary.
11.
Look in the Fuel Setting and Related Information Fiche for the full load setting for the engine you are adjusting.
12.
Turn the synchronizing pin in until dial indicator (5) reads the full load fuel setting. The full load setting is a reference position and is a temporary setting used to adjust the torque rise cam position.

Put dial indicator (5) with the 5P7263 Contact Point in the 5P4814 Collet. Install dial indicator (5) and the collet in the threaded hole for plug (3). When the contact point seats against the fuel stop lever, slide the dial indicator in or out until it reads zero. Now tighten the collet just enough to hold dial indicator (5) at this position.
REMOVE GOVERNOR TOP COVER 7. Cover. 8. Gasket. 6.
Remove the bolts that hold cover (7) in position. Lift cover (7) off the governor and remove gasket (8).
The purpose of this procedure is to hold the fuel control linkage at the full load setting while the torque rise cam is adjusted.

13.
Dial indicator (9) must read 1.00 + 0.05 mm, if it does not, an adjustment is needed. Loosen the bolt that holds the cam enough so the cam can be moved, but keep the bolt tight enough to provide a small drag on the cam.
14.
Slide the cam to cause the torque control lever and dial indicator contact to lift 1.00 + 0.05 mm.
15.
Tighten the bolt while the cam is held in place. This adjustment of 1.00 + 0.05 mm positions the torque control lever so the torque rise (additional fuel) begins to occur at the correct engine speed.
