View Full Version : Marlin 39A eject?
October 3, 2004, 02:09 PM
I inherited a Marlin 39A that was my father in laws. It's been 8 years since his death, and I just brought it out to shoot for the first time to shoot it. I can't get it to eject the used shell casings. I have to pick out the casing after each shot. The rifle works perfectly, other than that. I shot about 200 rounds the first time out. Could it just need a good cleaning, or is there something more seriously wrong with it. I not a gun fanatic....yet, so I don't know much about them yet. Give me time! Any help or pointers would greatly be appreciated. Thanks.

If the ejector is a fixed one (think 1911 type ejector or Ruger Ranch), then check to see if it's the right length. It may have broke and if it's too short, replace it. If it's the spring & plunger type, it probably needs soaking in solvent to free its movement.

I being mechanically inclined, but not know much about rifles, should I be able to take this rifle apart to check the ejector mechanism, and still be able to put it back together. Or, should I leave that to a more qualified person or gunsmith?

I think the ejector is fixed to the left side of the receiver (the action breaks into left and right halves, after loosening the thumb-screw). It could be the ejector is missing or broken. Improper assembly or disassembly could very well damage it. Numrich/Gun Parts has 39 parts, if you need a new ejector.

This should help you identify parts etc.
edit: by the way, if you buy parts, going directly to marlin. I just bought a new firing pin for my 39A from a parts dealer. Didn't work. Sent it back and went directly to marlin. Works perfectly now.

The ejector on a Marlin 39A is set in the left receiver wall. It has a screwhead that can be turned a half turn to hold it out of the way of a cleaning rod. Referred to as "rivet" no 22 in the ref drawing. If it were put back together after cleaning without releasing the ejector, it would not eject but there would be no missing or broken parts, just a screw to turn until the ejector popped out into operating position.

Here's an online manual for the Marlin 39A rifle.
This will show you the proper way to disassemble the rifle, which is something the customer was able to do for cleaning.
The ejector assembly is on the left inside receiver wall. It's held in place by two small screws on the left outside of the receiver.
As Jim says, inside on the front of the ejector assembly, there is a small, "half head" screw that's used to hold the ejector down so a cleaning rod will pass without being interfered with.
The "usual" causes of ejector problems on the Marlin are:
A broken ejector spring.
A fouled, gummed up ejector.
The ejector locking screw has gotten turned, and locked the ejector down.
In any case, you should be able to fix it yourself, and if you're unsure of your skills or lack good gunsmith's screwdrivers, any competent gunsmith can do it for you.

I realize you probably have had your answer sometime ago, but here is
what I did with my Grandfather's 22 rifle. I figured he had always used
22 short ammo which built up carbon, not letting a 22 long go in. I
took a #2 drill (.221 dia.) and reamed the chamber the depth needed
for a 22 long. It worked perfectly.

Since I haven't figured out how to post a question, I'll put it in the form
of a reply.
I've cleaned a cousins 39A trying to see why it will not load. He has shot
it many times, but just quit loading. The carrier rocker seems to be worn.
Could that be the problem? If not, any suggestions?

Not enough info to determine the problem.
Is the gun failing to feed a shell from the magazine, failing to feed one into the chamber, or is the shell getting jammed during the feed cycle?
The Marlin carrier seldom ever wears out or gives any trouble other than it and the entire action getting fouled. A good first step is to field strip the gun and give it a good cleaning and fresh lube.
Don't disassemble anything you don't have to. With the receivers separated and the bolt out, you can get to most everything for cleaning.
Here's a link to a current factory manual. Use it to disassemble and reassemble the gun.
NOTE: When preparing to separate or reassemble the receivers, make sure the hammer is FULLY COCKED to prevent bolt and receiver damage.
Here's an exploded parts view:
Note that this is for an older rifle. Later, the carrier was changed slightly with a spring loaded button instead of the flat rocker.
With the receivers apart, you can look at the right side with the carrier and operate the lever while watching operation.
Things to look for that can cause failures to feed:
Check the shell release in the left receiver...Part number 24.
Check to make sure it's not broken, weak, or impacted with grit and won't release a shell out of the magazine.
When the bolt closes the pointed triangular part on the bottom presses the release into the receiver and releases one shell. If the release is dirty or weak, it may not release a shell properly.
Make sure the magazine tube isn't gummed up and the spring has enough tension to push shells into the receiver.
The actual carrier almost never gives any problems unless the gun has been tampered with, or is so badly worn the lever can't raise the carrier.
This is rare.

The shell release is working when I use a small screw driver to press it in
with the bolt in place. The shell comes out and stops against the bolt
protrusion. Beyond this point is where the problem seems to be. With the
receiver back together the shell never makes it on to the carrier. I've
ordered a carrier rocker & a cartridge cutoff from Jack First Inc. Hope
these will do the trick. Will let you know.
Thank you Dfariswheel for your reply.

is it your ejector or your extractor? I just got a used one from the gunshow and it would pull the shell halfway out and the extractor would let go of the rim. I took it apart and cleaned everything well, then worked a shell casing in/out of the extractor to make sure it grabbed. Then I got a .22 brush and cleaned the chamber area very well. After that I ran 6 rds through it quickly in the backyard with no problems. The extractor is very cheap to replace, but mine was just gunky. I may have to replace it soon, but it is runnign fine now.
