Note: For the sake of writing the instructions
for the disassembly and reassembly of the bolt, the names or nomenclatures
in the above diagram are Surplusrifle.com's estimation of the correct
nomenclatures and quite possibly not the actual nomenclatures.

Disassembly
Instructions |
 |
| 1)
Note the direction the safety lever is installed on the bolt (as
shown in figure 1). It is actually possible to install
it backwards. |
 |
| 2)
The key to disassembling the bolt is to compress the striker
spring in the direction shown in figure 2.
Note: To the left of the arrow is the spring retainer
with a detent for you to place a punches tip and move it in the
direction of the arrow.
|
| Warning: The striker spring is a very strong
spring and requires a lot of pressure to compress and hold compressed.
Be cautious when attempting this procedure because the spring and
other parts can shoot out of the bolt at high velocity. |
 |
| 3)
Decock the bolt and let the striker spring expand. Note:
this disassembly can only be accomplished if the bolt body
is held in a vise or flat on a surface with a c-clamp. Figure
4 shows how the bolt should be positioned in the vise to gain
access to the striker spring and retainer.
|
 |
|
4) I cheat and use a jeweler's flat blade screwdriver
to insert the tip between the top coils of the striker spring
and then compress it. Then while holding the striker spring,
I use my other hand to take a punch and move the spring retainer
towards the compressed spring. I find this method easier because
you have less chance of loosing grip on the retainer because
the striker spring is fairly difficult to compress.
|
 |
|
5) While keeping the striker spring compressed,
move the safety lever to the right or left and pull out until
it comes free of the bolt.
|
 |
|
6) Be very careful to release pressure on the striker
spring slowly or it will fly out and across the room.
|
 |
|
7) Remove the striker and striker spring.
|
 |
|
8) Separate the striker and striker spring.
|
 |
|
9) Remove the bolt handle and spring follower.
|
 |
|
10) Separate the spring follower from the bolt
handle (as shown in figure 10).
|
 |
| 11) Figure
11 shows the punch pointing out the firing pin.
Note: I don't recommend attempting to remove the firing pin
or the extractor. Both can easily be cleaned while still
attached to the bolt.
|
 |
|
12) Figure 12 shows the punch pointing to the
firing pin's retaining pin.
|
 |
|
13) Figure 13 shows the punch pointing out the extractor.

|
Reassembly
Instructions |
 |
| 15)
Install the spring follower in the bolt handle (as
shown in figure 15). |
 |
|
16) Place the bolt body in the vise with the flat
part facing upwards. Insert the bolt handle into the bolt
body.
|
 |
|
17) Make sure the spring follower is in the furthest most
position (as shown in figure 17).
|
 |
|
18) Slide the striker spring onto the striker.
|
 |
|
19) Make sure you install the striker and striker
spring with the flat piston shaped end inside the bolt.
|
 |
|
20) Figure 20 shows the properly installed
striker and striker spring.
|
 |
|
21) Place the spring retainer on the striker
with the small detent arm placed in the follower's channel
.
|
 |
|
22) Figure 22 shows the punch pointing to the side of
the spring retainer with the ridge/lug that fits into the
channel/guide in the safety.
|
 |
|
23) Figure 23 shows the punch pointing to the
safety's channel/guide that the spring retainer's
ridge/lug fits into.
|
 |
|
24) After placing the spring retainer back into
the rear of the bolt, the striker spring must be compressed
and the spring retainer pushed inside the bolt to
allow the safety to be attached.
|
 |
|
25) Figure 25 shows the two guides/keys that are on the
safety. They must be lined up with the slots in the rear
of the bolt assembly for the safety to be reinstalled.
|
 |
| 26)
Make sure the safety lever is placed in the correct
direction. With the bolt situated as shown in figure 26,
the safety lever should point down. Align the safety's
guides/keys in the slots in the rear of the bolt.
While keeping the spring retainer and striker spring
compressed, push in on the safety and turn to the right or
left.
Slowly release pressure on the striker spring, while still
holding onto the safety to catch the striker spring
and retainer if the safety is not secure.
If you aligned the guides/keys correctly the bolt is assembled.
If not, repeat steps 21 to 26.
