Shaft Bearing End Clearance
Tighten adjusting nut to remove all clearance and seat bearing cups. At this point shaft should turn with dry bearing at torque of 60 lb. in. (6.8 N m) in addition to seal drag. Then back off the adjusting nut the number of notches indicated in the chart and install the lock. Drive the front bearing cup to the front by striking the output end of the shaft with a soft hammer. The end clearance should now be as indicated in the chart. Where shim adjustment is used, tighten the retainer without shims until shaft turns with dry bearings at torque of 60 lb. in. (6.8 N m) in addition to seal drag. Measure the space between the retainer and carrier and add .013 in. (0.33 mm) to this measurement. Remove the retainer, then install shims and retainer and cap screws with locks. Drive the front bearing cup to the front by striking the output end of the shaft with a soft hammer. The end play should now be .006 to 010 in. (0.15 to 0.25 mm).Clutch and Mounting Adjustment Check
At time of installation, check the flywheel and flywheel housing face and bore run out.Electronic Overspeed Switch

ELECTRONIC OVERSPEED SWITCH
5. Verify button. 6. Reset button. 7. "LED" overspeed light. 8. Seal screw plug (overspeed). 9. Seal screw plug (crank terminate).1. Remove lockwire and seal from seal screws (8 & 9). Remove seal screw (8) from access hole for overspeed adjustment screw.2. Use a small screwdriver and lightly turn O.S. (overspeed) adjustment potentiometer twenty turns in the direction of "MAX ARROW" (clockwise). The overspeed adjustment screw is made so that it can not cause damage to the potentiometer or be removed if the adjustment screw is turned too much.3. Run engine at 75% of desired overspeed setting rpm. Make reference to the SPEED SPECIFICATION CAHRT.4. With engine at 75% of overspeed setting rpm, push VERIFY pushbutton (5) and hold in. Turn O.S. (overspeed) adjustment potentiometer in the direction opposite of "MAX ARROW" (counterclockwise) slowly until "LED" overspeed light (7) comes on. Engine will shut down if speed switch is connected to the fuel shutoff solenoid and/or air inlet shutoff solenoids.5. To reset speed switch, push in reset button (6). Air inlet shutoffs must be manually reset.6. Slowly turn O.S. (overspeed) adjustment potentiometer approximately one turn clockwise and do Steps 3, 4 and 5 again. More adjustment may be needed to get the correct setting. Turn adjustment potentiometer clockwise to increase speed setting and counterclockwise to decrease speed setting. Turn adjustment potentiometer very slowly only a small amount at a time until adjustment
