VALVE REMOVAL

head. Remove the reed.

VALVE INSTALLATION
a. Attach discharge reeds and valve backing plate to valve seat. Torque screws to 12-15
inch-lbs. Inspect to see that valve rests flush against seat.
b. Apply a light film of appropriate grease to the new O-rings.
c. Install the large o-ring in the head and the small one on the valve seat assembly. Install
the valve seat with the discharge side of the seat going into the head and the spring pin
entering the small hole in the valve seat
d. Set the suction reed on the valve seat using a small amount of compatible O-ring grease,
which will hold the reed in place when the head is installed on the cylinder. If a new reed
is used, bend the tab to a 45 degree angle into the slot provided in the valve seat. Do not
put grease on or near the valve finger. Note: a 2nd o-ring can be installed to assist in
holding the suction reed in place during assembly.
e. Replace the O-ring on the cylinder liner. Note: if cylinder has been removed, make sure
valve cutout in top of cylinder is oriented to coincide with suction valve in head.
f. Carefully install the head assembly, making sure the suction reed valve does not fall out
of place.
Note : it may be easier to mount the head on the cylinder off the compressor
and then install the two together. Install nuts and tighten sequentially in 5 ft-lb.
increments to 30 ft-lbs.
