ASA KNOB
The ASA Knob may occasionally need to be removed
for cleaning or lubrication, especially if the Shocker
®
CVO has
taken a hard dive into a muddy or sandy bunker, driving debris
into the ASA around its knob. As with all maintenance, this must
be done only with the Shocker
®
CVO unloaded and degassed.
Unscrew the ASA Knob, as if turning the air supply off, but
continue unscrewing until the knob comes free of the ASA
[FIG 18].
The screw threads of the ASA may be lubricated with GR33SE
TM
,
but only place an extremely thin layer of GREESE
TM
on the
pin. Excess grease can clog the ASA’s filter. Take care when
reinstalling the ASA knob, to be sure it is not cross-threaded.
ASA POSITION
The ASA position may be adjusted to achieve
a custom balance or fit with different air systems. To move
the ASA, remove the ASA knob, and use a 3/32-inch hex key to
loosen the ASA lock screw [FIG 19] one-half turn. Slide the ASA
to the desired position, then lock it in place by tightening the ASA
lock screw. Reinstall the ASA knob.
REMOVAL
To remove the ASA, follow the ASA position
directions, but further loosen the ASA lock screw until it allows
the ASA to slide free of the grip frame. When reinstalling the
ASA, very lightly lubricate the air rail seal assembly face with
GREESE
TM
and press it into the frame with thumb pressure to
make sure it sits flush with the rail. Slide the ASA forward until
it is flush with the front of the grip frame, then tighten the ASA
lock screw.
DISASSEMBLY
Full disassembly is only necessary to replace a
leaking pin o-ring. This is accomplished by using a 7/64-inch hex
wrench to unscrew the stainless nut from the back of the ASA.
Seated in the front of the stainless nut is the ASA pin o-ring. This
should be inspected and replaced if it shows any signs of wear
or damage.
Removal of the regulator’s internal components is an advanced
maintenance procedure that should only be performed when
needed to repair a leak or lubricate seals if velocity becomes
inconsistent with fresh, good quality paint and a clean bolt
assembly.
SPRING PLATFORM REMOVAL
With the Shocker
®
CVO
unloaded and degassed, use a 5/16-inch hex key to unscrew the
spring platform base [FIG.. 21] from the vertical regulator portion
of the marker’s body. If the hex key cannot fit far enough into the
spring platform to get a good grip, use a 5/32-inch hex key to
turn the velocity adjuster inward (counter-clockwise, it is reverse
threaded) to expose more of the hexagonal flats in the spring
platform. The adjuster spring is now attached to the back of the
reg piston (VRG205) and will not drop freely.
SPRING PLATFORM ASSEMBLY
Additional parts will come
out, stacked inside the spring platform. These include the
spring guide [FIG. 22A], regulator washer [FIG. 22B], relief valve
[FIG. 22C], relief valve spring [FIG. 22D] and velocity adjuster
[FIG. 22E]. The spring guide acts as a positioning seat for the
regulator spring. The velocity adjuster is the base on which the
spring guide sits. Turning the velocity adjuster changes the
elevation of the spring platform to put more or less pressure
on the regulator spring, ultimately determining the gas pressure
inside the Shocker
®
CVO. The relief valve is a miniature, non-
adjustable regulator that vents air out through the middle of the
velocity adjuster if the Shocker
®
CVO is in danger of becoming
over-pressurized.
REGULATOR PISTON
Reach inside with an o-ring pick or
needle nose pliers and pull the piston out by its spring to pull the
regulator piston out [FIG. 23]. This is a difficult step. Patience
and a gentle hand are required to achieve success. Take care not
to slip and scratch the inner walls of the regulator body, as this
may cause non-repairable leaks that will prevent the regulator
from working correctly.
