|
|
|||
|
1. Disassembly of the internal trigger mechanism.
|
|||
|
|
|||
|
a. Remove the stocks from the pistol grip.
|
|||
|
|
|||
|
b. Remove the open ends of the trigger spring from beneath the
|
|||
|
trigger safety cam block. There are grooves on the bottom of the
|
|||
|
safety cam block that the open ends fit into.
|
|||
|
|
|||
|
c. The grip safety must now be fully AFT. Push out the trigger axle
|
|||
|
pin from the left to the right (as viewed from the rear). Lift
|
|||
|
out the trigger with its attached safety cam block and the
|
|||
|
trigger spring. The trigger spring will still be under slight
|
|||
|
tension, so be careful.
|
|||
|
|
|||
|
d. Drive the sear axle pin out from left to right. Lift out the
|
|||
|
sear, sear spring and the trip limit block. The trip limit block
|
|||
|
points to the rear of the trigger mechanism and sits between the
|
|||
|
sear spring coils.
|
|||
|
|
|||
|
e. Remove the spring from the grip safety. This completes the
|
|||
|
disassembly.
|
|||
|
|
|||
|
|
|||
|
2. Reassembly of the internal trigger group.
|
|||
|
|
|||
|
a. Make certain the sear spring is correctly positioned in the sear
|
|||
|
itself. The flat side of the sear is the bottom of the sear. The
|
|||
|
open portion of the sear points rearward. This position exposes a
|
|||
|
hole in each of the rearward pointing "arms. Insert the ends of
|
|||
|
the sear spring into their respective holes so that the closed
|
|||
|
loop portion of the spring is above the two coils in the spring.
|
|||
|
|
|||
|
b. Seat the sear by increasing the spring tension. Do that by
|
|||
|
pressing the closed loop against the inside front face of the
|
|||
|
trigger housing.
|
|||
|
|
|||
|
c. Holding the sear and sear spring in this position, begin feeding
|
|||
|
the sear axle pin in from the right side. The right end of the
|
|||
|
sear axle pin has the screwdriver slot in it.
|
|||
|
|
|||
|
d. After positioning the sear axle pin through the rightmost sear
|
|||
|
spring coil, set the trip limit block down between the two coils,
|
|||
|
pointing rearward. Then push the sear axle pin on through the
|
|||
|
trip limit block, second sear spring coil and the rest of the
|
|||
|
sear until the pin is set flush with the outside trigger housing
|
|||
|
surface.
|
|||
|
|
|||
|
e. Rotate the sear axle pin using a screwdriver until the flat face
|
|||
|
on the sear axle pin is positioned so that the grip safety bar
|
|||
|
will slide under the sear axle pin.
|
|||
|
|
|||
|
f. Position the trigger spring so that the open ends are pointing
|
|||
|
rearward AND the straight portion connecting the two coils is
|
|||
|
resting near the inside bottom of the trigger housing.
|
|||
|
|
|||
|
g. Drop the trigger into its slot in the trigger housing and between
|
|||
|
the two coils in the spring.
|
|||
|
|
|||
|
h. Assure that the grip safety is positioned FULLY REARWARD and then
|
|||
|
start pushing in the trigger axle pin with its screwdriver slot
|
|||
|
end on the right (as viewed from the rear of the trigger
|
|||
|
housing).
|
|||
|
|
|||
|
i. Push the trigger axle pin through the first coil of the trigger
|
|||
|
spring. Hold the trigger so that the trigger axle pin may be
|
|||
|
pushed through the trigger and the second coil. Look at the left
|
|||
|
side of the trigger housing. Using a screwdriver of the
|
|||
|
appropriate size, insert the screwdriver into the trigger axle
|
|||
|
pin's slot (right end) and rotate the pin until the flat side of
|
|||
|
the trigger axle pin is parallel to the top flat portion of the
|
|||
|
safety bar (NOT the grip safety bar!). Then push the trigger axle
|
|||
|
pin on through until it stops.
|
|||
|
|
|||
|
j. The open ends of the trigger spring must now be positioned under
|
|||
|
the safety cam block and into the spring retaining grooves on the
|
|||
|
underside of the safety cam block. Take your time completing this
|
|||
|
step. A seam ripper available at any fabrics shop aids this step
|
|||
|
or you can grind a notch in a screwdriver blade (which ruins the
|
|||
|
screwdriver and why we recommend a seam ripper).
|
|||
|
|
|||
|
k. This completes the reassembly of the Uzi internal trigger
|
|||
|
mechanism.
