Step 8

Install the cylinder sleeve into the 

grooves of the compressor body 

and line up the holes for the piston 

retainer plate. Use two of the new 

screws provided to secure the piston 

retainer plate (Recommended 

Torque: 34-38 in lb). Repeat Step 4 

thru 8 for the second cylinder before 

moving on to Step 9.

Step 7

Place the retainer plate and and 

piston cup on top of the new piston 

cylinder sleeve. Flip over to ensure 

the piston cup is properly aligned 

within the cylinder sleeve.

Step 9

Use a small pick tool to remove 

the two o-ring gaskets and two 

cylinder gaskets from the bottom 

and top of the valve plate.

Step 10

Remove the leaf valves. The leaf 

valves are originally installed with 

threadlock. We recommend using a 

propane torch or other heat source 

to soften the threadlock before 

removing the screws. Apply heat 

for approximately 5-20 seconds and 

gently remove the screws (Fig. 1). 

Save the screws but discard the leaf 

valves (Fig. 2). Repeat this process for 

all four leaf valves. NOTE: On the top 

leaf valves, also save the valve limiter 

as this is needed when reinstalling 

the new leaf valves.
