Disassembly / Reassembly 

 

 
 
 

 
 

 
 

 

 

 

 

Step 4

 

Remove air valve end cap to expose air 
valve spool by simply lifting up on end cap 
once air valve bolts are removed. 

 

 

Step 5

 

Remove air valve spool from air valve body 
by threading one air valve bolt into the end 

of the spool and gently sliding the spool out 
of the air valve body

Inspect seals for signs 

of wear and replace entire assembly if 

necessary. Use caution when handling air 
valve spool to prevent damaging seals. 

NOTE: 

Seals should not be 

removed from assembly.  

Seals are not sold separately. 

Step 6

 

Remove pilot spool sleeve 
retaining snap ring on both sides 

of center section with snap ring 
pliers. 

 
 
 

 
 

 
 

 
 

 

 

Step 7

 

Remove pilot spool sleeve from  
center section. 

Step 8

 

With o-ring pick, gently remove the o- ring 

from the opposite side of the “center hole” 

cut on the spool. Gently remove the pilot 
spool from sleeve and inspect for nicks or 
gouges and other signs of wear. Replace 

pilot sleeve assembly or outer sleeve o-rings 
if necessary. During re-assembly never 
insert the pilot spool into the sleeve with the 

“center cut” side first, this end incorporates 

the urethane o-ring and will be damaged as 
it slides over the ports cut in the sleeve. 

NOTE: 

Seals should not be 

removed from pilot spool.  
Seals are not sold separately. 

Step 9

 

Check center section Glyd™ 

rings for signs of wear. If 

necessary, remove Glyd™ rings 

with o-ring pick and replace.
