Removing the Flapper Valves

Note: We  recommend  you  remove  and  replace 

one flapper valve at a time. This will help to 
simplify  the  repair  process  and  orient  the 
flapper valve correctly on the valve plate. 

1. If you are replacing a flapper valve on the  t o p 

side of the valve plate (side facing the head), 
remove the flapper valve screw (1) with a 1/4" 
hex socket, lift off the valve keeper strip (2), lift 
off the valve restraint (3), and lift off the flapper 
valve (4).

2. Remove any debris from the valve plate with 

a damp, lint free cloth. (Soaps and detergeants 
should  not  be  used  due  to  the  potential  for 
corrosion from soap residue.)

3. Place the valve plate on the compressor housing 

and orient it as illustrated.  Note the orientation 
of the valve ports.

4.  Orient  a  new  flapper  valve  (1)  over  Port  1. 

Observe the location of the notches (2) at the 
end of the flapper valve.2.  Orient  a  flapper 
valve (1) over Port 1. Observe the location of 
the notches (2) at the end of the flapper valve 2. 
Orient a flapper valve (1) over Port 1. Observe 
the location of the notches (2) at the end of the 
flapper valve.
