Problem with Wolff SP101 Spring Kit

Gentlemen,

I purchased the Wolff Spring Kit for my new SP-101 and have run into a problem I would like some advice on.

My digital trigger pull gauge only reads up to 12 lb pulls, and my SP would not even register on it, meaning the double action pull was over 12 pounds. So I replaced only the mainspring with the Wolfe 10 lb mainspring. After reassembling the revolver, I dry fired the weapon in the double action mode successfully, but when I went to single action mode after a few successful cockings of the hammer, the hammer would no longer cock. The only way to make the gun "live" again was with a double action pull of the trigger. This problem was especially noticeable if I tried to cock the gun into the single action mode with the barrel pointed upwards.

I decided to go back to the stock mainspring and this single action problem disappeared completely. I then decided to try and install the 12 lb Wolff mainspring and test it. The single action problem returned exactly as it was with the 10 lb mainspring.

I figured the stock mainspring working at 100% was more important than lightening the trigger pull so I once again reinstalled the stock spring. Now the revolver is doing the same exact thing (refusing to cock into the single action mode every so often) with the stock spring installed. I'm more than a bit confused. Do any of you guys have any advice?

Thank you in advance,
Jon

Someone should be able to help soon. I just didn't want you thinking that people were looking at the post and not answering. I haven't the slightest idea why that is happening but I will be looking here for the answer. There are people here who know these revolvers inside and out.

I also just changed the main spring in my SP 101 today to the 10# spring and it worked just fine. I will be interesting to see the answer to your problem. I am sure you will get your answer soon.

JC676, First we need to know more about not cocking. Does the hammer move at all? Is it stalled with a fraction of an inch movement or does the hammer pull back but not catch the sear notch? This makes a huge difference in trouble shooting.

Possible the hammer strut is in backwards. It is possible to install it wrong, even though the spring retainer is in correctly. It rubs on the casting at the top.

I put my Mainspring Seat in backwards one time, and it did something similar to what you are describing.

I had the exact same problem! I took the damn thing apart three or four more times, trying to figure out what I had done wrong. Finaly, after putting it aside until my blood pressure returned to normal (about two weeks) I studied the ibok and schematics and finally found the cause. For $10 I'll e-mail the answer. Ok, Ok, just a little humor.
The answer is on page 5 of the ibok, first paragraph, "Initial Timing." A few drops of oil solved the problem for me, at least temporarily, but I won't really trust the gun until I've run a few boxes of ammo through it, and that will have to wait for this damn rain to stop.

Iowegan,

The hammer will start the cocking process but is stopped after a very short travel... approximately a quarter of an inch. Thank you for responding.

I wish I had the IBOK, but I don't. I joined the forum and found out about them (IBOK's) a bit too late. I do plan on ordering Iowegan's newest offering as soon as payday gets here. I will go ahead and add some lube to the revolver tomorrow. Like you, I'm too frustrated to actually play with it anymore tonight. Thanks for your response.

The exact cause is the cylinder latch not dropping down to release the cylinder. The latch (part 5) is on a very thin pin (part 57) and is pushed by a tiny spring/plunger (parts 7 & 31).
The spring/plunger seemed to be binding, so a drop of oil seemed to solve the problem. (Much to my amazement - and joy) However, I did notice that the latch seems really sloppy on the little pin, and it seems like a bushing of sorts would help to keep it in line better, so it doesn't have a tendency to bind in the future. I intended to ask Iowegan for his opinion. Double check my part number references; my eyes are a bit old and tired.

stuart and powdermonkey,

I've double and triple checked the hammer strut and mainspring seat. They appear to be installed correctly to me, but I will check again tomorrow. Thanks for your help.

Thanks again! I'll try that tomorrow... or as soon as my nerves settle down after thinking I somehow ruined a brand new revolver. I'll let you know how it works.

Hope it works. I was a bit distraught too. We northern Kalifornians have to stick together, to survive our liberal-dominated PRK. (I'm in Mendocino County)

This sounds like a mess. Take some pictures of your re-assembly process and post them! I just installed a wolff 12 pound spring and have no problems. Just DOn't pull the trigger while the gun is dis-assembled! It will be trouble!

Cat,

OK, this morning I reinstalled the 10 lb Wolff mainspring and made sure to put a couple of drops of CLP in all the openings on the frame, including the cylinder latch area. After reassembly, everything appears to be normal. The key word here being "appears." The cylinder did bind one time while cocking the gun into the single action mode, but I noticed that the hammer pivot assembly was trying to back out. I pressed it back in with my finger and the gun continued to function properly. This happened with the grips properly installed. I continued to dry-fire the gun double action and cock it into single action mode and the hammer pivot assembly continued to try and back out of position. This obviously shouldn't be happening. Any thoughts on this one?

I'm from Napa County, and am 3 years away from retiring and getting the flock out of Kommiefornia. Can't wait!!
