| Step 1 |
[lo res - 67 K][high res - 397 K] | Insert extractor spring (W10028) and extractor pin (W10027) into the receiver (W10001). Place the extractor release (W10029) in position with the hole facing the end of the barrel and toward the top side of the receiver (W10001). While holding the extractor release (W10029) in position, insert the extractor release screw (W10029) through the hole in the extractor release (W10029). Use a screwdriver to tighten the extractor release screw (W10029). |

|
| Step 2 |
[lo res - 52 K][high res - 317 K] | Continue assembling the extractor mechanism components by inserting two extractor springs (W10028) and two extractor pins (W10027). The extractor (W10025) and extractor release cam (W10031) are held in place under pressure by the block pin (W10054). Place the extractor release cam (W10031) in position and insert the block pin (W10054) just far enough to hold the release cam. |

|
| Step 3 |
[lo res - 98 K][high res - 607 K] | With the extractor release cam (W10031) being held by the block pin (W10054), insert the extractor (W10025) into the slot of the extractor release cam (W10031) and press the block pin (W10054) through the hole in the extractor (W10025) and the hole on the other side of the extractor release cam (W10031). Pressure must be applied to the extractor (W10025) to align the holes. Make sure the flat part of the block pin (W10054) is aligned with the set screw hole and install set screw (W10055) to hold the block pin (W10054) in place. |

|
| Step 4 |
[lo res - 32 K][high res - 181 K] | Insert the extractor release cam plunger (W10051) into the hole next to the extractor mechanism components just installed. Insert the spring (W10050) into the extractor release cam plunger (W10051). Place the plunger plug (W10052) on top of the spring (W10050). Press the plunger plug (W10052) down flush with the extractor release cam plunger (W10051) and insert a punch into the hole on the side of the receiver (W10001). Make a note as to where the plunger plug (W10052) is in relationship to the extractor release cam plunger (W10051). This will allow for proper alignment when reinstalling the pin (W10053). Remove the punch. If the pin is not installed correctly it will cause the plunger mechanism to seize. |

|
| Step 5 |
[lo res - 40 K][high res - 243 K] | After removing the punch, insert the pin (W10053) into the hole in the side of the receiver (W10001). Press the plunger plug down the same distance as it was held by the punch in the previous step and drive the pin (W10053) into the hole with a hammer. Be sure the pin hole is aligned. A burr on the pin can cause the plunger mechanism to seize. |

|
| Step 6 |
[lo res - 36 K][high res - 211 K] | To reinstall the cocking cam assembly drop the spring (W10050) into the hole in the cocking cam bushing. Place the cocking cam plunger (W10049) on top of the spring aligning it with the hole. Depress the cocking cam plunger with a punch. |
| [Back to top] |
|
| Step 7 |
[lo res - 25 K][high res - 148 K] | When inserting the shaft (W10015) make sure the corners of the shaft are aligned up and down. While holding the cocking cam plunger (W10049) down with the punch, insert the shaft (W10015) through the first cocking cam bushing. The corner of the shaft should hold the cocking cam plunger down while inserting the shaft (W10015). |
| [Back to top] |
|
| Step 8 |
[lo res - 92 K][high res - 564 K] | Align the cocking cam (W10013) into the receiver (W10001) so the cocking pawl points toward the back of the receiver (W10001). Press the shaft (W10015) through the hole in the cocking cam (W10013) and into the opposite side cocking cam bushing. Rotate the shaft to align the holes for the shaft pin (W10016). Using a hammer, drive in the shaft pin (W10016) locking the cocking cam (W10013) to the shaft (W10015) to the cocking cam (W10013). The cocking cam assembly should rotate freely. When driving shaft pin all the way in, lightly peen the lip of the hole. This will prevent the pin from falling out. |

|
| Step 9 |
[lo res - 104 K][high res - 646 K] | Rotate the gun right side up. Begin the breech block reassembly by inserting the sear (W10006) into the hole in the breech block (W10003) with the notch in the sear (W10006) facing the slot in the breech block (W10003). Insert the trigger (W10022) into the slot of the breech block (W10003) making sure the sear (W10006) rises and falls as the trigger (W10022) is rotated. Using a hammer, drive the trigger pin (W10024) into the breech block (W10003) securing the trigger, countersinking it slightly. Insert the sear spring (W10008) into the same hole as the sear (W10006) and tighten the set screw (W10011) flush with the surface of the breech block (W10003). The trigger mechanism will not function correctly if the set screw (W10011) is over tightened. If the set screw (W10011) is loose when reaching the flush position with the breech block (W10003) use a center punch and stake the set screw (W10011). |

|
| Step 10 |
[lo res - 82 K][high res - 494 K] | Lay the breech block assembly on the receiver (W10001). Insert the firing pin (W10004) into the breech block assembly with the slot in the firing pin (W10004) facing the barrel. Insert the firing pin spring (W10007) and the sleeve (W10005) making sure the slot in the sleeve (W10005) is aligned with the slot in the firing pin (W10004). Compress the firing pin spring (W10007) by pressing on the sleeve (W10005) and insert a punch through a hole in the side of the breech block (W10003), holding the compressed firing pin spring (W10007) and sleeve (W10005). Using a hammer, drive the roll pin (W10012) into the hole opposite the punch, driving the punch out with the roll pin (W10012). While driving the roll pin (W10012) though the hole and punch out, cover the firing pin hole to prevent the firing pin and sleeve from accidentally flying out. Countersink the roll pin (W10012) to avoid it dragging on the sides of the receiver (W10001). |

|
| Step 11 |
[lo res - 57 K][high res - 341 K] | Place the breech block assembly in the receiver (W10001). Rotate the tool upside down. Attach the roller chain (W10018) to the pistol grip linkage with the connecting link (W10020). After the breech block is assembled into the receiver, dry fire the industrial tool and listen for the release of the firing pin to ensure the breech block is assembled correctly. |
| [Back to top] |
|
| Step 12 |
[lo res - 71 K][high res - 432 K] | Place the breech block stop bracket (W10033) on the receiver (W10001) making sure the four holes are aligned with the holes on the receiver. Install two screws (W10037) and lock washers (W10036). Attach the guard (W11005) with the remaining four screws (W10037) and lock washers (W10036). |
| [Back to top] |
|
| Step 13 |
[lo res - 48 K][high res - 280 K] | Rotate the tool rightside up. Secure the breech block assembly into the receiver (W10001) by inserting the breech block pin (W10009) through the holes in the receiver (W10001) and the breech block (W10003). Align the breech block pin (W10009) flush with the receiver (W10001). Attach the breech pin retainers (W10044) on both sides of the receiver (W10001) using the button head screws (W10044). |
| [Back to top] |
|
| Step 14 |
[lo res - 41 K][high res - 251 K] | Attach the operating handle (W11018). Put the breech block assembly in the down position to provide an alignment surface for the deflector (W10062). Attach the deflector (W10062) to the receiver (W10001) with two socket head screws (W10037) and lock washers (W10036). Check ejector and trigger operation and reassemble hanger hardware. |
