1) Figure 1 shows the 1891 Argentine Mauser.

Safety: With the rifle pointed in a safe direction, open the bolt and make sure the rifle is not loaded.

2) Open the bolt.
3) Pull the bolt to the rear of the receiver.
4) Open the bolt stop and remove the bolt.
5) To remove (rotate) the bolt sleeve you need to pull back on the cocking piece and keep it in extended. I have tried different methods including wire, string, and the edge of a counter top.  The method I found to be most effective and safe is the edge of a counter top.
6) Place the edge of the cocking piece on the edge of the counter top as shown in figure 6.
7) Pull the bolt body down so the cocking piece is fully extended as shown in figure 7.
8) Slip a washer or coin (penny) in the gap between the cocking piece and bolt sleeve. Allow the cocking piece to retract back and stop on the edge of the coin.
9) Figure 9 shows the extended cocking piece held in place by a coin stuck in the gap between the bolt sleeve and cocking piece.
10) Rotate the bolt sleeve counter clockwise to unscrew from the bolt body.
11) Separate the bolt body from the firing pin assembly.
12) Place the tip of the firing pin against a block of wood. Compress the bolt sleeve against the firing pin spring so the gap between the bolt sleeve and cocking piece widens enough to remove the coin.
13) Place the tip of the firing pin against a block of wood. Compress the bolt sleeve against the firing pin spring so the cocking piece completely clears the bolt sleeve and can be rotated.
14) Rotate the cocking piece counter clockwise. It is threaded and you will need to completely unscrew it to be removed.
15) Once unscrewed, remove the cocking piece.
16) Allow the firing pin spring to slowly expand.
17) Remove the bolt sleeve.
18) Remove the firing pin spring from the firing pin.
19) Unscrew the safety screw.
20) Remove the safety screw.
21) Allow the safety detent and safety detent spring to fall out of the safety.
22) Separate the safety detent and safety detent spring.
23) Remove the safety from the bolt sleeve.
24) Figure 24 shows the disassembled bolt.

We do not recommend removing the bolt extractor. This should only be done if the extractor is damaged and needs to be replaced.

Reassembly Instructions

25) Insert the safety into the bolt sleeve.
26) Combine the safety detent and safety detent spring.
27) Insert the safety detent and safety detent spring into the safety with the safety detent going in first.
28) Replace the safety screw.
29) Tighten the safety screw.
30) Combine the firing pin spring and the firing pin.
31) Note that the firing pin has a groove that protrudes the length of the firing pin. This groove is mated to a channel in the bolt sleeve.
32) Place the tip of the firing pin against a block of wood. Place the bolt sleeve over the firing pin. Make certain to align the groove on the firing pin with the channel in the bolt sleeve. Compress the firing pin spring by pushing down on the bolt sleeve.
33) Place the cocking piece over the threads of the rear of the firing pin and rotate clockwise.
34) Rotate the cocking piece until the sear lug (the protruding side of the cocking piece) is aligned to the channel in the bolt sleeve (as shown in figure 34).
35) While keeping the bolt sleeve compressed insert a coin in the open slot between the bolt sleeve and cocking piece as shown in figure 35.
36) Allow the firing pin spring to expand and the lip of the bolt sleeve will hold the coin in place against the cocking piece as shown in figure 36.
37) Insert the firing pin assembly into the bolt body.
38) Rotate the bolt sleeve clockwise, screwing the threaded part of the bolt sleeve into the bolt body.
39) Figure 39 shows the bolt sleeve in its final position.
40) Rest the edge of the sear lug (cocking piece) against the edge of the counter top and pull the bolt body down so the gap between the bolt sleeve and the cocking piece expands enough for the coin to fall or be pulled  out.
41) Insert the bolt in the receiver.
42) Figure 42 shows the completed bolt disassembly and reassembly.
