NOTE: The purpose of the following procedure is to correctly position the connecting 

rod assembly on the the motor shaft before the Loctite

® 

 bond has dried.

STEP 4. 

 Hold the sleeve down against the housing with one hand, and slowly rotate 

the eccentric with the other hand.  As the piston travels up and down it will also rock 

from side to side. This is a feature of the WOB-L Piston. If it rocks from front to rear, the 

connecting rod is misaligned on the eccentric. If front to rear rocking is detected, loosen 

the connecting rod clamping screw and repeat Steps 1, 2, and 3. If the connecting 

rod cannot be properly aligned, contact the nearest service center. 

STEP 5.

 Install the new O-ring into the 

bottom of the valve plate assembly, 

seating it firmly into the groove with 

your finger or blunt object. 

STEP 6. 

With the sleeve located and 

firmly seated on the housing, replace 

the valve plate as shown in Fig. #8. 

Make sure the top edge of the cylinder 

sleeve locates in the O-ring groove in 

the bottom of the valve plate.

STEP 7. 

Clean the inside of the head with 

a soft clean cloth. Install the new gasket, 

seating  it  firmly  in  the  groove  with  your 

finger or blunt object.

STEP 8.

 Place the head on the top of the 

valve plate. The exhaust fitting should be 

facing  the  rear  of  the  compressor,  and 

the smaller cavity inside the head will be 

over  the  curved  valve  restraints  on  the 

top of the valve plate. Install the 6 head 

screws  and  tighten  to  45  in-lbs.  NOTE: 

The  handle,  if  present,  should  extend 

over the exhaust fitting to provide proper 

balance.
