1. Pull back the operatinghandle to lock the bolt inthe open position, and setthe safety in the on-safeposition. Depress the

barrel slightly toward therear. (This will release thetension on the Magazinecap)Unscrew and remove theMagazine cap. Take offthe fore-end and barreltoward the front.

2. The ejector is mountedin a T-slot at the left rearof the barrel extension,and is retained by ariveted cross pin. In somemodels, it is solidly fixed,and in others it has anopening at the center andslides to the rear, In bothcases, it should beremoved only for repair.The riveted pin is drivenout inward. It isrecommended that only aqualified gunsmith attempt

to replace this part.

3.Remove the bronzefriction piece and itsattached spring toward thefront. Note that this pictureshows the rings in a

normal setup for high tomagnum loads.

The picture is a look at therings set in the light showsthe rings in the lowpowered or light loads.

This next picture showsthe rings bevel and flatside. Note when the ring ison the bottom close to thereceiver the bevel goestoward the receiver andwhen on top the flat sidegoes toward the spring.

This next picture is ashowing of the rings andtheir position for 3magnum guns.

4. Remove thecompression ring towardthe front. If the gun hasbeen used with light loads,the ring will be foundstored at the bottom ofthe recoil spring next tothe receiver.5. Remove the recoilspring toward the front.

6. Hold the operatinghandle to restrain the bolt,depress the carrier latchbutton, and ease the boltforward to the closedposition. Remove the lockscrew and then remove

the stock screw, in thelower tang. . (Note: thescrews have a very thinslot and your screw driverblade should be thinenough to fit, this will deterdeforming the screw slot,You can modify a regularscrewdriver by filing theblade thinner to fit the slot)Remove the Buttstock

toward the rear. If it is verytight, bump the front of thecomb with the heel of yourhand or a rubber hammer.

10. Remove the carrierspring from its post on theleft side of the triggerhousing. Note that onearly guns, this spring will

be mounted on a postinside the receiver, andmust be detached at thefront, then moved off itspost inward for removal.

11.Move the safety to the

off-safe position, tip thesafety sear forward ,restrain the hammer, pullthe trigger, and ease thehammer forward until itsroller disengages from thetip of the hammer spring.

12. Punch out the hammercross pin, and remove thehammer from the trigger

housing.

15. Lift the hammer springat the front, and remove itupward and toward thefront.

16. Push out the smallcross pin in the rear of thetrigger housing, Removalis easier if he triggerspring is slightlydepressed in the vicinity ofthe pin. (Note: Newermodel have a slots cut oneach side of the inter partof the spring recess. Thereare tabs on both sides ofthe safety spring that slideup and into the slots)17. Remove the triggerspring upward and towardthe rear. Or slide it out if it

has rails cut into thereceiver.

18. Invert the triggerhousing over the palm ofthe hand, and move thesafety to free the detentball. If it does not drop outeasily, tap the housingwith a nylon or woodhammer.

19. Punch out the triggercross pin and remove thetrigger upward.


10/25

20. Remove the safety tothe right.

21. Remove the lockscrew and the large carrierpivot screw on each sideof the receiver.


11/25

22. Remove the twosections of the carrier

downward. Note that onearlier guns, the carrierwill be a single part. Latermodels are a two-partsystem.


12/25

23. The carrier dog and itsplunger and spring areretained on the rearsection of the carrier by across-pin that is riveted in

place, and should beremoved only for repair. Ifit is necessary, punch outthe pin inward (toward theleft) and be sure thecarrier section is wellsupported.

24. Restrain the boltspring plug at the rear ofits housing, push out thecross pin, and remove theplug, spring, and followertoward the rear. (Note:The spring is very strong,and is under great tension.Make sure to control it andease it out) It is alsopossible to unscrew thehousing (tube) from therear tang of the receiveron older models, Newermodels are soldered intoplace). I would not removethose that screw in duringnormal cleaningbreakdowns only forrepair.

25. Move the bolt back tothe position shown, untilthe locking block latch pinis aligned with the exit cutin the lower edge of the

ejection port. Insert apunch through the accesshole in the left side of thereceiver, and push out thepin toward the right.

You punch from the other

side through a punch port.

Here you can see the pinas it starts out the rightside.


14/25

26. Removal of the pin willrelease the locking blocklatch from the bottom ofthe bolt. Remove the latchand its spring.

27. Move the bolt to therear, swing the link baroutward. Restrain theoperating handle, andmove the bolt forward,leaving the handle at therear.


15/25

28. Swing the link barinside, and remove thebolt assembly toward thefront.

29. Move the operating

handle unit forward, andremove it from the ejectionport.

30. Punch out the crosspin at the rear of the bolt

toward the right, andremove the firing pintoward the rear.


16/25

31. Push the front of thelink bar upward, tippingthe locking block out thetop of the bolt, and removethe assembly upward.Punch out the cross pin atthe lower rear of thelocking block and it willrelease the link bar for

removal.


17/25

32. The extractors andtheir coil springs areretained on each side atthe front of the bolt byvertical pins. Punch outthe pins downward, andtake the extractors andsprings out toward eachside.


18/25

33. Remove the magazinecutoff spring screw,located on the left side atthe forward edge of thereceiver, and take off thespring toward the front.

34. On early Guns, the

magazine cutoff, carrierlatch, and shell stop areretained by vertical screwpins and required aspecial tool to removethem. Now they are heldinto place by role pins. Toremove the pins youpunch them out in anupward direction towardthe top inside of the

receiver through holesprovided for the pins toexit. Use a role pin punchto remove the magazinecutoff pin upward.


19/25

35. Remove the magazinecutoff toward the left

36. Punch out the shellstop pin upward, andremove the shell stop andits spring from inside thereceiver.


20/25

37. Punch out the carrierlatch pin upward, and takeout the latch and itsrelease button from insidethe receiver, Note that the

carrier latch spring isriveted in place, and is notremoved. If the spring isbroken the entire piece isreplaced.

38. Insert a screw driver inthe opening center of themagazine spring retainer,and pry the retainer out,moving the screwdriver to

raise the retainer equallyaround the edge until it isloose enough to remove.Remember: Themagazine spring is undertension, be sure to controlthe retainer and ease it outuntil the tension isremoved.


21/25

Remove the spring, plug,and follower toward thefront. Removal of themagazine cutoff springscrew will have freed the

magazine tube, and it canbe unscrewed from thereceiver. (It is notrecommended that youremove the magazine tubefor normal takedown butcan be removed if repair isnecessary. The tube isvery tightly screwed intoplace and will requireeffort to remove.

Reassembly Tips.

You can easily reassemble in reverse of the lesson on disassembly. But there are afew things I would like to add to help in the reassembly of the gun.


22/25

1. When replacing thepivot pins for the carrierlatch, shell stop, andmagazine cutoff, drive theroll pins in the same

direction as they wereremoved. Upward. Takecare to make sure theparts are properly alignedbefore driving the pins intoplace. Insert a punch toinsure alignment, thenhold the parts in place witha fingertip while the pinsare inserted. Be sure thepins are not driven too

deeply, as their upperends can enter the bolttrackAs you can see in the nexttwo pictures Im pointing atthe rail to watch so thatthe pin does not inter therail slot.


23/25

And this one shows all thepin in an exaggeratedstate so you can seewhere they come out andnot let them go too far into

this slide area as youreinstall. (note: this is alsothe direction they areremoved.

2. In the later guns thathave the two piece carrier,the arrangement of theparts may be difficult forthe novice. In this picture,the parts are shown in theproper position. Hold togather and insert them inthe bottom of the receiveraligning the holes on the

side of the receiver withthe holes in the carriersides. Insert both carrierscrews before you releasethe carrier.


24/25

3. When installing thecombination trigger andsafety detent spring. Use atool to depress the springat the cross pin location.

And insert a small punchto hold the spring downwhile putting in the crosspin. It will be necessary todepress the spring on theother side as the pin isinserted, and the end ofthe cross pin must also bedepressed as it enters thehole on the other side ofthe tang.

4. When installing thetrigger group in thereceiver. Insert the frontfirst. You will need to holdpressure to keep it in linewith the front hole. Onceyou have the front pin in

place but not screwed youcan pull the action handleback about one inch andthe rear of the triggerguard will go in place.Make sure that the carrierspring is riding on thecarrier dog as you areattempting to put the frontof the trigger guard inplace.

5. when replacing thecompression ring andfriction piece at the front ofthe recoil spring, theseparts should be in theposition shown for mediumto heavy leads, with theconcave inner surface ofthe ring toward the front.For light loads, place thecompression ring concavetoward the receiver asshown.


25/25

6. Take note when yourreinstalling the carrierscrews on each side. Youwill notice a notch in eachscrew. These screws are

not interchangeable. Eachnotch was cut for thatscrew to line up with thelock screw hole. You mayhave to back off a fractionof a turn for each but thenotch must line up with thelock screw hole.The figure below show thenotch in the screw head.This is the end of lesson 2
