Ruger MKII Reassembly-help

[offthepaper]

Here I sit, and decided to disasemble my Ruger MKII for the first time in eons, and am having problems reassembling it (go figure). When I finally get the bolt in and get the pin up through the top of the reciever (so that it does'nt keep wanting to lower as I fit the rest of the assemblyinto the rear of the frame), this takes some time, the bolt won't pull back all the way. Any ideas? I've only had this pistol apart twice in the last 7-8 years, so I never did really have much experience in the stripping of it. Thanks in advance.

The hammer stut is not lined up on the mainspring. Pull the mainspring housing back out. Hold the muzzle down and pull the trigger and hold it. Get a pencil and push the hammer forward so the hanging strut is above the crosspin in the frame. Let go of the trigger. Put the mainspring bolt stop up through the frame and bolt. Hold the muzzle straight up and then close the mainspring housing and snap it shut.

The reason the pin "wouldn't stay up" was that the hook in the MSH was hitting the strut when you tried to close it.

I think yzguy still has a video of this on his Ruger Mark II website.

The secret to reassembly of these things is to orient it in the correctly so gravity is pulling everything into the proper position.

It's not intuitive at all but once you do it couple of time you'll have it down pat.

Fun, isn't it?

Do you have the manual? The instructions are pretty clear. It's still frustrating when you haven't done it for a while. Kruzr said it right, above.

You can download the manual from ruger's website.

There is a modification I've seen where the mainspring is removed and replaced using a nut on a threaded bolt stop pin.

 

[offthepaper]

I understand about the pin going into the cup, but EVERYTIME I get near that position the pin begins to lower through the reciever.

 

[offthepaper]

I must be the biggest idiot in the world.
do you know where I can get the mod kit?

 

[Kruzr]

Are you pushing the hammer forward so the strut is above the crosspin in the frame?

You hold the muzzle straight up and close the MSH.

Follow the pictures in the Reassembly part.

do you know where I can get the mod kit?

I don't thik it's a kit but I'll check. I won't be able to get back to you on it anywhere soon enough to dent the frustration.

I have always found the folks generally understand situations better with visual aids.

What the problem that is being encountered offthepaper (and MT) is the following:

In the picture on the left, the hammer strut is resting on the sear spring stop pin. This prevents the strut from falling to its normal resting place on the main spring plunger located in the main spring housing (the part that you pull out when you disassemble). With the hammer prevented from falling back out of the way, it obstructs the bolt from traveling its full length.

What you want is what is pictured in the second photo on the right where the strut is not hung up on the pin. What Kruzr is describing is how to move the hammer forward slightly so that the strut can clear the pin, then when you re-install the housing, point the gun straight up 12:00 so that the strut will fall back and not get hung up on the pin when the hammer also falls back.

If the housing goes back in without any resistance, the strut is hung up, the hammer is forward, and the bolt will not cycle. There must be tension on the main spring in the housing as the hammer should be in the cocked position when re-installing.

+1 to that. You need to go there, sit down with the pistol in front of the computer and follow the directions to a T. I have a MKIII and after half dozen takedowns I still need the directions.

Everytime I have had problems I have missed one of the steps. Go slow, pay attention to detail and it isn't really that big of deal. The key is in the detail. My Airmen read the job guides all the time but they only "READ" them half the time.

Excellent hksw!

offthepaper,
Now that you are looking at it on a new day, remove the MSH and try again.
You do not need the threaded bolt stop pin.
You can do this.
Follow the instructions exactly, making sure to keep the muzzle upwards as told in step 13.

Unbelieveable!!!!!!
I just got home from work after a short sleep and attempted again. Before making any moves, I first read every post and read all the sent instructions, then tried again for the 2 gazillionth time (but the first time today). It dropped right in on the second attempt! I thought I was doing the same thing as last night (all night), but this time it just dropeed right into place with not much more than a little wiggle to lock everything in place.
I really can't express my thanks and gratitude to everyone enough with their input and advice. The manual information was very helpful, as I bought the gun used and never had one. But the real ice breaker was the great photos from hksw, they were crisp, clear, well lighted, and much better detail than the drawings and other darker hard to make out photos (not posted here, but on other sites I was checking). You not only made it possible for me to reassemble my MKII, but also helped lower my blood pressure about 100 points. Again my sincere thanks to Kruzer, Plexreticle, Katonk, 5 Wire, Tyesai, Xavier Breath, and a very special thanks to hksw. This is why I love THR so much. Kinda the cyber Band of Brothers.

Fantastic!
Good show offthepaper!

Now that's the value of this forum!

Everyone give themselves a virtual backslap!

I know I'm a little late here, but I discovered that it helps to guide the hammer strut in place using a jeweler's screw driver while inserting MSH.
