BLADE TRACK.
Blade track is the ability of one blade tip to follow the other, while rotating, in almost the same plane. Excessive difference in blade track - more than .0625 inch - may be an indication of bent blades or improper propeller installation. Check blade track as follows:
1.  
With the engine shut down and blades vertical, secure to the aircraft a smooth board just under the tip of the lower blade.  Move the tip fore and aft through its full “blade-shake” travel, making small marks with a pencil at each position. Then center the tip between these marks and scribe a line on the board for the full width of the tip.

2.  
Carefully rotate propeller by hand to bring the opposite blade down.  Center the tip and scribe a pencil line as before and check that lines are not separated more than .0625 inch.

3.  
Propellers having excess blade track should be removed and inspected for bent blades.  Constant speed propellers should be checked for parts of sheared “O” ring, or foreign particles, which have lodged between hub and crankshaft mounting faces.  Bent blades will require repair and overhaul of assembly.

PROPELLER GOVERNOR.
REMOVAL OF PROPELLER GOVERNOR.

1.  
Remove the upper engine cowl.

2.  
Disconnect the control rod rod end bearing from the governor control arm.

— Note —
Have a means available to catch oil that will drip from governor when the oil line is disconnected.
3.  
Disconnect the governor oil line from the governor.

4.  
Remove the governor mounting stud nuts.  It will be necessary to raise the governor as the nuts are being removed before the nuts can be completely removed.

5.  
Remove the mounting gasket.  If another unit not substituted, and the governor is to be removed for a considerable length of time cover, the mounting pad to prevent foreign matter.damage.

INSTALLATION OF PROPELLER GOVERNOR.
1.  
Clean the mounting pad thoroughly.  Ensure that there are no foreign particles in the recess around the drive shaft.

2.  
Place the governor mounting gasket in position with the raised portion of the screen facing away from the engine.

3.  
Align the splines on the governor shaft with the engine drive and slide the governor into position.

4.  
With the governor in position, raise the governor enough to install washers and start mounting nuts. Torque nuts 110 to 150 inch-pounds.

5.  
Connect the control rod rod end bearing to the governor control arm.

RIGGING AND ADJUSTMENT OF PROPELLER GOVERNOR. (Refer to Figure 61-3.)

1.  
Start engine. Park 90° to wind direction and warm in normal manner.

2.  
To check the high rpm, low pitch setting, move the propeller control all the way forward.  The governor (speed) control arm should be against the high rpm (fine) adjusting screw. (Refer to Figure 61-3, Sheet 1 of 2). With the throttle full forward, engine rpm should be 2700 rpm. If not, adjust the high rpm setting as follows:

A.  Shut down the engine.  Remove the upper engine cowl.
— Note —
One revolution of the fine adjustment screw will increase or decrease the engine speed approximately 20 rpm.
B.  Using the (fine) adjustment screw, adjust the governor to 2700 rpm.  Loosen the high rpm (fine adjustment screw) locknut.  Turn the screw clockwise to decrease engine speed or counterclockwise to increase engine speed.
C.  Install upper engine cowl.  Repeat step b to ensure proper rpm setting.
D.  After completing the high rpm adjustment, run the self-locking nut on the fine adjustment screw against the base projection to lock.
E.  Check that the governor control arm is adjusted to the proper angle on the control wheel as shown in Figure 61-3 (Sheet 2 of 2).
