Author Topic: Extractor Replacement Rem 742 (Read 1418 times)

Can I replace a riveted extractor with a rivetless extractor in the Rem 742?
I hate to fool with the riveted one if I don't have to. I have done it several times but I hate to fool with that itsy bitsy rivet even 'tho my jig makes it easier.
I sent Brownell an email asking them but you know how long that takes.
Seem like I remember doing it before, but I can't remember. Deer season is coming up and I'm bogged down with work.

Call Brownells tech line. I've had great results!! I don't believe it's possible to replace the old style extractors with the new. The change to rivetless extractors was one of the rasons the Sako style extractors became so popular.. and the reason the extractors with rivets are being made again.. Good luck and I truly know what you mean about being buried..

Thanks!
I was hoping against hope. I noticed that Brownells doesn't list the riveted extractor for the 742. Do you think the Rivet listed is actually the extractor? Over $3 for a rivet is ridiculous but not much surprises me these days.
I guess that 742's will be around for a long time but I've had nothing but trouble with them every since they came out. Hard to make a profit repairing them considering time and conservative :roll: owners of them.
I hate to tell them that the factory quit repairing them years ago but will offer to sell the owner a 7400 for more than a discount house sells them for.
"When ethics and money bump heads, money always wins." That reminds me, I've got to call Brownells like you said. Can't wait for an email answer.

Brownells lists the extractor you're looking for in catalog 55 on page 9. It's listed for the 700 but all the riveted Remington extractors are the same. My latest catalog seems to have obsconded!! Somebodies gonna fry for that.... In any case Brownells has the extractor you are looking for and they sell them complete with 2 rivets.. and you'll need them if I remember the process right... good luck!! jerry :grin: :-)

Thanks, it on pg. 10 in Cat#56. I guess the price went up since the last time I ordered one.
You're right, I probably will need the extra rivet. I repeat, I hate this.
I remember bending an extractor too much and had to replace it. It is a good hunting rifle but I am thinking about not taking any more in to repair. I have quit taking Nylon 66's when they come in disassembled by amateur "smiths". If you don't have a mechanical aptitude higher than a chimpanzee there are some firearms which you shouldn't take apart or even shoot in some cases. I'm dreading those sore fingers.
Thanks gunnut, appreciate it.

Perhaps you have a solution or even insight into a problem with the 740/742's which I've been seeing a lot of lately. The problem is worn breech bolt cam slots. The wear is at the forward motion impact point and I've seen several that were worn so badly that the locking lugs were over rotating and cutting notches in the slide path on the inside of the receiver. Parts are basically not available(needs a new breach bolt) and I'm a bit worried about welding them up.. Have you or have you seen a solution to this problem. I really hate to tell some of these guys their favorite deer shooter is 'not fixable'. Thanks! and good luck with that extractor..

Being as it was designed as a hunting rifle, not as a pleasure "Rambo" shooting rifle, it isn't surprising that the rotating lugs wear out, especially since practically no one ever puts grease on the lugs.
I would be reluctant to heat the head to welding temp. Wouldn't you? Might try it with my own rifle with mig or tig and let my mother in law try it out. Wish someone would make a new bolt and restrict who they sold it to or provide replacement as a service. Good business for a beginning 'smith. Lots of other rifles need bolts. Insurance would be out of sight. Older Mini 14's need them also.
I tried replacing the barrel in one, but that didn't work. Sent it to Rem and they said they wouldn't repair it but offered the customer a new 7400 at a price "an offer you could refuse" which exceeded discount house price.
I'm going to quit taking them in 'cause the ethical thing to do is weld it up and declare it a wall hanger. If I hand it back and some yoyo gets injured, a shark could possibly make me liable.
Could convert them with a breechblock to a blowback action. :wink:

I found a guy who welded the bolt face when the lip surrounding it chipped out. He used a heat sink built up using strips of copper. A hole thru a sheet of copper was the base. Bolt was set down trhu that and the lugs forward covered using strips with one end touching the bolt and the other end pointing away from the bolt centerline. The result was a stack with the bolt at the center made of copper(I believe aluminum would also work). The stack was kept cooled with water and the welding proceeded as usual. He said he would weld the cam slot up but didn't think he could recut it. Oh well... Good luck and hope the extractor works the first time!!
