--------------------------------------------------------------------------------

On dissasembly of my Marlin Camp I found a few things broken. One is the Hammer Strut Bridge (Marlin part #316275 or #28 on the parts blowup) that captures the Hammer Strut and Hammer Strut Spring. Mine fell out as it was broken and I have a replacement for it. I cannot determine how it is installed from the parts breakdown. It has a tang on either side and could be installed 2 different ways. Anybody that can asist? By the way, I beleive that this part broke because of the complete breakdown off the Buffer insert. I am replacing it and installing a 16lb spring as well. Strangely, it was working fine last time I fired it.
Thanks
DD

This part is easily seen by removing the stock, two screws, and the action, two pins.
It is at the back of the action on the underside. It is a small rectangular plate with a tang on either side, there is a slot in the middle for the hammer strut to pass trhrough, The Hammer strut spring is captured on the strut when the bridge is installed and it is captured whith the tangs through a hole on each side of the action just below the rearward pin that holds it all together. The tangs are offset. I need to know if the excess metal hangs below or faces up towards the top of the rifle. I called Marlin and left my name and number but they have not responded yet and the parts blow up does not show.
If some one could take a look at theirs I would appreciate it. I have tried to convince my wife to test it as is but she's too smart for me.

I'll have to take mine down and take a look. I will get back on ASAP. I have the 9 and 45 - great guns. the ladys love 'em too.

looks like the thick side goes up, but I'll check mine if 45 doesn't reply.

Thanks to both of you. I mounted it with the heavy side down but it could easily go the other way.
I love shooting it. Traded $150.00 for it a few years ago and bought 2 of the 30 round clips. They cycle flawlessly. Biggest problem I have is that I tend to carry it with my hand overlapping the clip release button. I have had to back track a few times to find it after it fell out on the ground. Like my dad always said "you have to be smarter than the equipment your trying to opperate".
Lots of fun.
I wil look forward to your responses.

I just took mine down (easy part) there is a 'shoulder' that points downward on the bridge. I think I'll order a replacement for mine, that's a weak link if ever I saw one. Good luck.

Great, thanks for the info. Thats the way I have it installed. I don't know if it broke because the buffer fell apart or he buffer fell apart because the bridge broke. I thought there was a bunch of dried wax in the action when I pulled it down but soon discovered that was the remnants of the buffer,
I appreciate it.

I had the opportunity to fire and fieldstrip the marlin camp a while back (great gun by the way) and I noticed that if the hammer is cocked when assembling/disassembling, then the hammer strut remains exposed behind the trigger assembly. This strut could (as the trigger assembly is lifted from the upper receiver) pry against the rear end of the reciever (made of steel) where the rear stock screw is placed. Now if the pressure is great enough, one could rather easily bend the hammer strut and possibly the strut bridge as well. This could be the reason why your bridge failed since I almost goofed on more than one attempt. Any thoughts??

The bridge on mine was missing one of the tangs and was bent in the middle, the whole thing had a curve in it. My buffer, the only part of it left in the action was the little knob that presses into the rifle to keep it there. The big square part of the buffer had been reduced to a pile of what looked like old dried up chunks of beeswax. I did'nt know it was missing untill I pulled up a parts manual on the net. I have not really tried to figure out how the action works but my first guess would be that the disintegration of the buffer allowed everything to move further back on firing thus putting extra preasure and stress on the bridge.
I bought this used probably 8 years ago and had have run several hundred rounds through it. I had never disasembled it until recently when curiosity got the best of me and figured maybe I should cleand the thing. Glad I did though.

I am supprised on how far down the hammer strut the bridge seats. You really have tho cmpress the spring a lot which leaves a bunch of the strut hanging out the backside by itself.

Hmmm...if the buffer was completely removed/destroyed, then that could be the cause for the bridge failure. What condition was the hammer strut in? Before taking apart your gun, did you ever have any problems with the trigger group or any problems whatsoever?

Amazingly, no. I had a few bad feeds but really don't recall any misfires or anything. I have not shot it since Sept 06 and I beleive it was doing well at the time. I would bet against it buts that the history.
