Installation
Instructions
1.)
Disassemble the firing pin from the bolt.
Next remove the spring from the factory
firing pin (wear safety
glasses).
2.) With the
spring removed, next remove the cross pin
in the bolt shroud to allow the pin to be
removed from the shroud (some models don't
require this).
3.) Screw the bolt shroud back in the rear of the bolt into its closed (fired) position. Screw the SpeedLock cocking piece all the way onto the new SpeedLock firing pin. Drop this assembly into the back of the bolt shroud. Check the bolt face to see the amount of firing pin tip protrusion.
Note: To avoid
inaccuracy in taking this measurement,
start with the pin threaded all the way
into the cocking piece.
4.) If the
pin tip isn't protruding from the bolt
face, remove the firing pin assembly and
loosen the cocking piece one turn at a
time, checking as you go. Repeat as
necessary until the correct protrusion is
attained. Be sure the bolt shroud is in
the fired position when checking pin
protrusion! Recommended protrusion is .060
inches, but that amount is not critical. A
safe, workable range is anything from
.025--.085 inches.
5.) When
protrusion is correctly set, remove the
firing pin assembly from the back of the
bolt, being careful not to let the cocking
piece move on the threaded portion of pin.
Put the cocking piece with the firing pin
set to a correct protrusion in a
non-marring vise and drill one 3/32-inch
diameter hole through the pre-drilled hole
in the cocking piece and drill completely
through the firing pin. This hole is
already pre-drilled through the cocking
piece.
6.) Insert
the cross pin (included) to secure the pin
and cocking piece.
7.) Fit the safety cam to the bolt shroud safety lever (so that the safety works). This may require removal of small amount of the SpeedLock firing pin directly in front of the safety cam notch on the cocking piece, as well as metal removal from the cam cut on the cocking piece.
8.) Cut the
cross pin notches in the firing pin (if
needed).
9.) If you
don't have the "A" spring retaining washer
and "B" half moon notch which retains the
spring on the pin (pre-64 models don't
have it) then call and order the parts
from us or a Winchester parts
dealer.
10.)
Reassemble with the included new SpeedLock CS Spring. Wear safety glasses. Lubricate the bolt shroud and bolt threads, safety cam notch, and cam finger cut with a good quality grease.
