| Step 1 |
[lo res - 27 K][high res - 165 K] | Remove deflector (W10062) by removing screws (W10063) and washers (W10036). |
| [Back to top] |
|
| Step 2 |
[lo res - 44 K][high res - 268 K] | Pull the operating handle (W11018) to the rear of the tool. Rotate the breech pin retainers (W10043) on both sides of the receiver (W10001) by loosening the hex head screws (W10075) and rotating the breech pin retainers (W10043) so they hang below the breech block pin (W10009). Push the operating handle toward the barrel of the tool and drive out the breech block pin (W10009). Cycle the operating handle backwards and forwards to loosen the breech block assembly. |

|
| Step 3 |
[lo res - 20 K][high res - 110 K] | If necessary, remove the hanger frame (W11006) by removing the socket head cap screw (W10040) from the bottom of the tool. Rotate the tool upside down to continue disassembly. |
| [Back to top] |
|
| Step 4 |
[lo res - 48 K][high res - 290 K] | With the tool upside down, remove the guard (W11005) by removing 4 screws (W10037) and lock washers (W10036). Remove the breech block stop bracket (W10033) by removing the two remaining screws (W10037) and lock washers (W10036). |

|
| Step 5 |
[lo res - 25 K][high res - 140 K] | Using a punch, drive out the pin (W10053) holding the extractor release cam assembly. IMPORTANT SAFETY TIP: Before removing the punch after driving out the pin (W10053), cover the extractor release cam assembly with your hand. There is enough pressure from the spring (W10050) on the plunger plug (W10052) to cause the plunger plug (W10052) to fly out of the hole. Remove the punch after confirming the extractor release cam assembly is covered. Then remove the plunger plug (W10052), remove the extractor release cam plunger (W10051) and remove the spring (W10050) from the extractor release cam plunger (W10051). |
| [Back to top] |
|
| Step 6 |
[lo res - 43 K][high res - 268 K] | Remove the warning labels (W100079) from both sides of the receiver. Note: If pressure sensitive labels were applied, do not reuse them. Order new warning labels from Winchester (W100079). To remove the block pin (W10054) from the receiver, loosen and remove set screw (W10055) from the bottom of the tool. Then using a punch, drive out the block pin (W10054). Leave the punch in until the next step. Note: When reinstalling block pin, make sure the flat area of the block pin is aligned with the set screw (W10055). |

|
| Step 7 |
[lo res - 66 K][high res - 392 K] | Before removing the extractor (W10025) place your thumb on the extractor to keep parts from flying out. With your thumb on the extractor, remove the punch. Then remove the extractor (W10025), remove the extractor release cam (W10025), remove two extractor pins (W10027) and two extractor springs (W10028). |
| [Back to top] |
|
| Step 8 |
[lo res - 26 K][high res - 149 K] | Disconnect the connecting link (W10020) from the roller chain 3-link assembly (W10018) and remove the breech block (W10003) from the receiver (W10001). |
| [Back to top] |
|
| Step 9 |
[lo res - 36 K][high res - 206 K] | Remove the operating handle (W11018) from the shaft (W10015) by loosening the socket head cap screw (W10060) and sliding the auxiliary handle (W11004) off the shaft (W10015). |
| [Back to top] |
|
| Step 10 |
[lo res - 33 K][high res - 195 K] | In order to clean the firing pin hole in the breech block (W10003), the firing pin sear (W10006) and the trigger (W10022) must be removed. Loosen and remove the sear set screw (W10011) and the sear spring (W10008). When reinstalling the sear set screw (W10011), tighten until the sear set screw (W10011) is flush with the surface of the breech block (W10003). If it is screwed in too far it will bind the firing pin. |
| [Back to top] |
|
| Step 11 |
[lo res - 29 K][high res - 174 K] | Drive the trigger pin (W10024) out of the breech block (W10003). Remove the trigger (W10022) from the breech block (W10003). Remove the sear (W10006) from the hole that held the sear spring (W10008) and sear set screw (W10011). |
| [Back to top] |
|
| Step 12 |
[lo res - 31 K][high res - 177 K] | Remove the firing pin assembly (firing pin spring (W10007), firing pin (W10004) sleeve (W10005)) from the breech block (W10003). Start by using a punch to drive out the roll pin (W10012). CAUTION: DO NOT REMOVE THE PUNCH UNTIL REVIEWING THE NEXT STEP. |
| [Back to top] |
|
| Step 13 |
[lo res - 47 K][high res - 282 K] | IMPORTANT SAFETY TIP: Before removing the punch after driving out the roll pin (W10012), cover the firing pin hole with your hand or with a shop towel in the palm of your hand. There is enough pressure from the firing pin spring (W10007) on the sleeve (W10005) to cause the sleeve (W10005) to fly out of the firing pin hole.
Remove the punch after confirming the firing pin hole is covered. After the punch has been removed from the breech block (W10003), remove the sleeve (W10005), remove the firing pin spring (W10007) and remove the firing pin (W10004).

|
| Step 14 |
[lo res - 26 K][high res - 155 K] | To clean the powder out of the firing pin hole in the breech block (W10003) use a 13/32 drill bit with a ground off tip. Before using the drill bit, spray the firing pin hole with a quick evaporating spray solvent such as an electrical cleaner. Never use petroleum based spray oils to clean the equipment or mount. Turning one direction only, with the flutes, insert the drill bit into the firing pin hole and scrape the bottom of the hole until clean. While continuing to rotate, slowly remove the drill bit. Then flush the firing pin hole again with the quickly evaporating spray solvent. Set the breech block (W10003) aside. |

|
| Step 15 |
[lo res - 78 K][high res - 453 K] | flutes, insert the drill bit into the firing pin hole and scrape the bottom of the hole until clean. While continuing to rotate, slowly remove the drill bit. Then flush the firing pin hole again with the quickly evaporating spray solvent. Set the breech block (W10003) aside. |
| [Back to top] |
|
| Step 16 |
 | If the extractor release (W10029) and the cocking cam (W10013) must be replaced, they must be ordered per a measurement. For the cocking cam (W10013), measure the distance from the center of the hole to the top of the pawls. The measurement for the extractor release (W10029) should be from the center of the hole to the top of the extractor release. |
| [Back to top] |
|
| Step 17 |
[lo res - 58 K][high res - 348 K] | To remove the extractor release (W10029), loosen the extractor release screw (W10029) which is found underneath the label. With your thumb put pressure on the extractor release (W10029) and pull the extractor release screw (W10029) out. Then remove the extractor pin (W10027) and extractor spring (W10028) for the extractor release (W10029). |
