5.  Replace  belt. 

NOTE:  The  belt  must  be  centered  over  the  grooves  on  the 

flywheel and motor pulley.

6.  Turn  the  wing  nut  on  the  hold  down  plate  until  it  makes  contact  with  the 

washer, plus one additional turn.

7.  Replace the belt guard

.

MOTOR PULLEY/FLYWHEEL ALIGNMENT

NOTE: Once the motor pulley has been moved from its factory set location, the 

grooves  of  the  flywheel  and  pulley  must  be  aligned  to  within  1/16"  (1.6 mm)  to 

prevent excessive belt wear.
The air compressor flywheel and motor pulley must be in-line (in the same plane) 

within 1/16" (1.6 mm) to assure belt retention within flywheel belt grooves. To check 

alignment, perform the following steps:
1.  Set the Auto/Off lever to "Off", unplug unit and relieve all air pressure from the 

air tank.

2.  Remove belt guard.
3.  Place  a  straightedge  against  the   

 

outside of the flywheel and the motor 

drive pulley.

4.  Measure  the  distance  between  the 

edge of the belt and the straightedge 

at  points  A1  and  A2  in  figure.  The 

difference  between  measurements 

should be no more than 1/16" (1.6 mm).

5.  If the difference is greater than 1/16" (1.6 mm) loosen the set screw holding 

the motor drive pulley to the shaft and adjust the pulley’s position on the shaft 

until the A1 and A2 measurements are within 1/16" (1.6 mm) of each other.

6.  Tighten the motor drive pulley set screw. 
7.  Visually inspect the motor drive pulley to verify that it is perpendicular to the 

drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If 

they are not, loosen the setscrew of the motor drive pulley and equalize B1 

and B2, using care not to disturb the belt alignment performed in step 2.

8.  Retighten  the  motor  drive  pulley  setscrew.  Torque  to  70-100  in-lbs 

(7.9-11.3 Nm).

9.  Reinstall belt guard.

AIR COMPRESSOR PUMP INTAkE AND ExHAUST VALVES

Once a year have a Trained Service Technician check the air compressor pump 

intake and exhaust valves.

AIR COMPRESSOR HEAD BOLTS - TORqUING 

The  air  compressor  pump  head  bolts  should  be  kept  properly  torqued.  Check 

the  torques  of  the  head  bolts  after  the  first  five  hours  of  operation.  Torque  to 

28–39 ft.-lbs (38.0-52.9 Nm).
