PILOT VALVE
PILOT VALVE
Disassembly of the pilot valve should only be
performed when necessary for repair. The internal parts of the
pilot valve are small and fragile and must be handled with care.
If necessary, use a magnifying glass to inspect and work with
these parts.
After removing the grip frame from the body use a 1/4-inch
wrench to unscrew the valve cap. The pilot valve’s upper o-ring
[FIG. 29] will remain seated inside the valve body, and it may
be removed with an o-ring pick. Inspect, clean and if necessary
replace this o-ring. Like the other o-rings in the pilot valve, the
upper o-ring should be very lightly lubricated with GR33SE
TM
.
An o-ring pick can be used to remove the pin cage [FIG. 30E]
from the pilot valve cap. The pin cage keeps the upper o-ring
seated. The valve pin [FIG. 30D] is held in place by the its clip
[FIG. 30A] and spring [FIG. 30B]. To remove it, pry the clip loose
from the pin with an o-ring pick, taking care to retain both parts.
The pin may then be removed from the opposite side so that
the lower o-ring [FIG. 30C] may be cleaned, inspected and if
necessary replaced. Clean and inspect the valve pin to be sure
it is not bent, and has a smooth surface with no chips around
the edge of its top end or where it steps from a larger to smaller
diameter in its middle.
The valve cap’s outer o-ring should also be cleaned, inspected
and if necessary replaced when the valve is apart.
Reassembly of the pilot valve is done in the reverse order of
disassembly. Take care not to apply excessive bending stress
on the valve pin when reattaching its clip.
BOLT CONTROL
29
PILOT VALVE O-RING
BOLT CONTROL MANIFOLD
The bolt control manifold [FIG.
31E] connects the supply of regulated compressed air to the
pilot valve and the forward control section of the bolt assembly.
At the front of the bolt control manifold is the rebuildable quick
exhaust valve (QEV) [FIG. 31D] that vents air from the control
section when the bolt closes to fire the Shocker
®
CVO.
Using a 1/16-inch hex key, remove the QEV mount screw [FIG.
32A]. Using a 1/8-inch hex key unscrew the gas-though bolt [FIG.
32B] from the manifold inlet at the rear.
Once removed, the bolt control assembly may be further
disassembled as needed for repair. The QEV slides off of the
manifold. The QEV may be disassembled by removing its pin
[FIG. 31C], sliding out the QEV core [FIG. 31A] and pushing the
QEV diaphragm [FIG. 31B] out with a 1/16-inch hex key. The bolt
control manifold [FIG. 31E] slides out of the pilot valve [FIG. 31F].
The trigger return magnet is secured in the bolt control manifold
by dimpling the aluminum manifold body with a hardened steel
punch. It is non-removable.
REASSEMBLY
Before reassembly, lubricate o-rings very
sparingly with GR33SE
TM
. Excess lubricant can clog small gas
paths in the pilot valve or QEV, preventing proper operation. Do
not lubricate the QEV diaphragm.
Reassemble in reverse order of removal and disassembly.
When reassembling, be sure the cone in the center of the QEV
diaphragm is pointed back, toward the pilot valve.
