SPROING! Fixing a Marlin Model 60 (really a 75C)


January 8, 2009, 05:34 PM
I own two Marlin rimfires, a Model 60 and Model 75C, that I've had for 26 and 20 years, respectively. Both were gifts from my granddad. So, suffice to say they have a lot of sentimental value. Besides that, they're both excellent shooters.

For those who don't know, the 75C is basically the same as the 60, only with a shorter barrel and mag tube. My 75C also has factory sling swivels, which my 60 does not have. Internally, they both function identically.

Enough prelude. Recently my 75C became finicky and would jam every 2-3 rounds. This is very unusual for this rifle. I partially disassembled the rifle and discovered that the plastic buffer in the action had fractured into about five pieces and that there were a lot of plastic shards inside the action. So, I ordered a new buffer from Brownell's.

To install a buffer in the Model 60/75C action, you have to separate the halves of the action and place the buffer on a pin at the action's rear. I understand that not all Model 60s require this much disassembly, because on some rifles the pins holding the action together can be individually removed. That's not the case with mine, though, and I had to dismantle the action just to get to the point of installing a new buffer.

And then, SPROING!

As I eased the action halves apart, the springs let loose. At least I was able to contain everything, but now I have a mess of springs to reassemble. At least the buffer went on smoothly. I managed to get everything back to where it should be, but then I discovered that the disconnector spring was worn out and would not stay where it should in the action. Besides that, I cannot depress the hammer spring far enough to attach the hammer spring bridge to the sides of the action so that everything stays put. I spent a lot of time trying to get it fixed, but I finally gave up and put all the parts away in frustration.

SO... Can anyone provide some ideas for getting this spring-loaded mess back together? Obviously, I'll need to get a new disconnector spring. The big problem, though, is getting the hammer spring into position and reassembling the action halves without launching the hammer spring bridge across my living room (again). I've put together some tricky firearm mechanisms before, but this one has me licked for now. I'd appreciate any help. Failing that, is there a Model 60 expert gunsmith I can ship this to? Will the Marlin factory work on a 20-year-old rifle if I ship it to them?

Thanks, and sorry for the long post.

Go to page 2 on this thread, I used it after the same thing happened to me.
Good luck! (It's really not that bad.)

Just to update anyone who may be interested in the mess I made of my Marlin 75C, it now appears to be fixed. Actually, I figured out how to reassemble to action halves a couple of weeks ago. The trick for me was to release the hammer mechanism to relieve the pressure on the hammer spring while everything is being put together. In retrospect, I doubt I'd ever have been able to reassemble the thing without relieving the pressure on that particular spring. After that, I had to wait a couple of weeks to get a new disconnector spring from Midway (Brownell's was out-of-stock). The package came the other day, and I was glad to have ordered two of the little buggers as extra insurance. After struggling with the first for ten minutes or so, I took out the second and could tell right away that the first was defective because it lacked a sufficient amount of wire on the end of the spring to stay where it was supposed to. I popped the second spring into place in about 30 seconds. Then, I lubed the action and reassembled the rifle. I still have to test it at the range, but I can already tell that the bolt moves more smoothly than it has in a long time. With any luck, it'll work well for another 20 years.

I've been trying to find a buffer and a recoil spring guide for mine but everyone seems to be backordered. I lost my grip on the guide and shot it across my shop. I think the gremlins found it.

I refurbished one of these that my dad picked up at a garage sale for something like $20, that was in horrible condition. Fortunately it was all easily cleaned up and turned out to be more dust and lack of cleaning than anything else. I got it back to its original glory, but part of getting it up and running was cracking open the receiver to deep clean all of the internal parts.

To call this a nightmare would be giving nightmares a lot of credit.

everyone seems to be backordered

I've been doing some long overdue maintenance on several of my firearms, and it seems that many parts for many different guns are backordered seemingly everywhere. I just check the usual sources (Midway, Brownell's, Numrich) to see who has what. Failing that, I check GunBroker and/or eBay. Beyond that, I ordinarily just order from Midway and wait. They're pretty good about estimating wait times, and in my experience most of the waits aren't as long as they say they may be. Your mileage may vary, of course.
