I've got a nice old Mossberg 352k that shoots very well, but sometimes doesn't cycle.I suspect it needs a good cleaning-but am reluctant to tear it down for fear of not getting the parts all back together properly.Is there a link to stripping these old semi automatics down?

I would just remove the takedown screw that holds the action to the stock. Once the action is removed, unscrew the plug from the back of the receiver and remove the bolt assy. Give everything a good cleaning and reassemble. It seems to me I read somewhere that there was an early type and later type of hammer (if I remember correctly). The later one is an improved version because of jamming. The new style can be interchanged. But this was awhile ago that I read it and I'm not sure of the model. I will try and find out.
 
This is not a substitute for a "real" cleaning...

If you're hesitant to take id down, you can thoroughly hose the action with brake cleaner until it comes out clear, while manually cycling the action. You should also be able to get at the bolt face with a toothbrush. If "dirt" is your issue, this will buy time until the rifle can be taken down and, cleaned properly.

If your patient and, keep track of what goes where (snapping pictures is a help) taking the rifle down is not a terrible experience. Be methodical and, patient...I've seen some really really really gunky .22's that, after a thorough cleaning, behaved like new.

Also, you can go "pro" and, have a smith do it too...this is their busy season though.
 
I assume by not cycling properly you are meaning it jams. I found what I was thinking about in my previous post. It has more to do with not firing as opposed to jamming but I will describe it anyhow. There were 2 styles of hammers and firing pins as the pins are prone to breakage on the 352K. I have shown a pic of the old style on the left and the new style on the right. They have to be changed in sets. Maybe this info will also be useful but your problem may just be dirt and maybe a weak spring.

it doesn't jam, it fires ok-and loads and ejects most of the time-but sometimes you have to push the bolt ahead to chamber the next round,its almost like the spring was weak-or maybe just ''gunked up''.
For a semi automatic-its very accurate-minute of grouse head
 
The old Mossys cannot be beat for over all accuracy. I have placed my 144 against many "big name" expensive guns and came out on top. The semi actions do get dirty and need a cleaning. after the rear plug is out you can remove the bolt ass'y and clean without disassembly ( i use wd40 or brake cleaner.) Just the firing pin may need a touch on the edges with a file to take off any burrs. Assemble dry after really scrubbing out the action housing and away ya go. The cleaning should cure the hesitation.
 
I took it ll apart, sprayed it with brake cleaner ,dried it off and reassembled it.I haven't take it to the range yet, but the action now slides smoothly.The only issue I can see is the safety seems to come partially on,and that possably is causing the hesitation.I never use a safety anyway,and if it was strictly up to me,I'd remove it,but I am reluctant to take things off.I'm not sure if the safety could be tighted up.
As I said-its a nice little rifle,I like the old mossbergs,got a 342,352 and a 144.The only issue with the 144 is the front sight[multiple beads]is loose,it should be tight.
 
Please be careful...

I'm no "Doctor" but, it would seem you have "Mossbergitis" Not a terrible malady (much better affliction than Ruger-eye) but, please be very careful with this kind of post....it is HIGHLY CONTAGIOUS!

Seriously, gald you're running more smoothly now
 
.22 semi actions get filthy real fast, and will cook regular lube. Use a new synthetic CLP-style and shoot it wet. You'll be amazed at how easy it is to clean in future.

The S106 front sight with selective apertures has a flat, thin "band spring" that keeps everything tight. If you remove the front sight you may find that the spring is broken in half.
Yes, sounds to me like you have Mossbergitis. They quit trying to cure me long ago. It's just as bad as Cooeyitis!!Laugh2
 
There really is no cure either...The only "medicine" I've found are .22 cal lead pills that get expelled out of the barrel( toward a target, yummy critter or, nuisance critter) Caveat...although it can serve to "suppress" the bug you run the risk of it exacerbating the condition.

Not the worst of ailments....Ljungman thumb, Ruger-eye and, Winchester-mania can all be devastating!
 
I stripped down my dads 352K last year for a thorough cleaning, probably the first time it has ever been done to that rifle. Once you start taking it apart it you will see how very simple it is.
