9. Examine the LEVER ARM (9) and compare it with a new one to
ensure that it is not bent or distorted in any way. Discard if
distortion is found.
10. Examine the POPPET SPRING (7) with a magnifier and com-
pare it with a new one to ensure correct tension and length.
Discard if found to be weakened or corroded.
11. Remove the POPPET SEAT (5) from the POPPET (6) with the
use of a dental probe and discard (Fig. 4). DO NOT attempt to
reuse it.
12. Examine the internal threads of the HOUSING'S Inlet Tube (8)
that holds the POPPET Assembly to ensure they are clean and
in good condition. Refer to the Cleaning Section of the General
Procedures (Doc. No. 12-2202) for instructions regarding the
cleaning of these Threads.
13. Inspect the overall condition of the HOUSING (8) to ensure it is
free of any stress cracks or other distortions, and that the Outer
Threads are in good condition. Discard if distortion is found.
14. Using the flat end of a brass O-ring Tool or a thin plastic probe,
carefully lift the Retaining Tab Slats of the EXHAUST COVER
(13) from the Retaining Tabs located on the Base of the HOUS-
ING (8) (Fig. 5). Once the EXHAUST COVER is disengaged
from the Retaining Tabs, push straight down on the Exhaust
Porting of the EXHAUST COVER to remove it from the HOUS-
ING.
15. Inspect the overall condition of the HOUSING (8) and the
EXHAUST COVER (13) to ensure they are free of any stress
cracks or other distortions. Ensure that all Threading on the
HOUSING is in good condition. Discard either if any distortion or
damage is found.
16. Using a soft probe, inspect the condition of the EXHAUST
VALVE (14) to ensure that it is supple and free of any tears or
corrosion, and that it seals completely around the seating sur-
face of the HOUSING (8).
NOTE: If the EXHAUST VALVE (14) is in good condition, it is
not necessary to remove it. The HOUSING (8) may be
cleaned with it attached.
17. If the EXHAUST VALVE (14) requires replacement, it may be
removed by grasping it at the Flange and pulling it straight out,
snipping the Retainer Stem if necessary. Discard.
