2. Wash the reed valves, stopper, and cage assembly in
parts-cleaning solvent and blow dry.
3. Inspect the reed stopper height. Using a caliper, mea-
sure the distance from the seat to the bottom outer tip
edge of the stopper. Measurement must not exceed
specifications. If measurement is not within specifi-
cations, either bend or replace the reed stopper.
4. Inspect the reed-to-seat clearance. Using a feeler
CM161
gauge, measure the clearance. Clearance must be less
than 0.008 in. If clearance is not within specifica-
tions, replace the reed valve.
5. To assemble, place the reed valves on the cage with its
clipped corner positioned to the lower right hand corner
of the cage. Place the reed stopper assembly into posi-
tion and secure with the screws tightened to 8.5 in.-lb.
