I have been having problems with my Uberti Walker. It is a Navy arms Uberti. While shooting the gun at the range I began having problems getting it to cock. I thought it was due to fouling. If I place clockwise pressure on the cylinder it will cock and rotate just fine. When I try to cock it with just the hammer it is locked.

Being inspired by your helping Ratdog with his problem I decided to take it apart and see if I could discover the problem (yes I do have gunsmiths' screwdrivers).
I cleaned and reassembled the weapon. Same problem. I believe the bolt is not unlocking correctly.

1. Can anyone help me trouble shoot this problem?
2. What kind of lubricant is used on the inside parts?

How many rounds ya got

through it so far ?
You can pull the bolt and make sure it is fitting inside the cylinder notches , manually , that's a good start :D
Those are machiend so tight Higene , and that's was why the Dragoon finally got the different style of cylinder noches too .
One of my cylinder notches on one of my Walkers is snugg and it takes effort to cock it into place . You have to be pruposeful cocking these guns , soft cocking isn't helpful at all . I diamond dremelled it ever so slightly and cured that problem . Sounds to me like your bolt may be ever so too large .
I use Moly based grease on my innards after metal has set to itself . I also think you need to lube the gun well .

Walker Problem

I took the action apart again and put gunslick on bearing surfaces. In cycling the action without the springs hooked up, the pin on the hammer that trips the bolt is sliding past the bolt trip part. The worn part that trips the bolt is a pressed machined pin. It looks like that could be replaced or repaired at a gunsmith's shop with a high end press. It also looks like one could spread the split tail of the bolt so that the piece would catch the the trip pin on the hammer.

Are you starting to get a line around the cylinder were the bolt would ride on it? That would be an indication of the bolt raising to soon. Take the cylinder out and operate the gun, you can see what the bolt is doing. It should not raise until it is near the notch in the cylinder.

Is it possible the barrel is rubbing against the cylinder? How much end play or cylinder gap do you have?
 
Not intending to imply anything... but, when you cleaned it... did you brush and use solvent inside the cylinder where it spins on the base pin? Did you do the same with the base pin? Part of my problem I had was that I'd forgotten to clean the petroleum based gun oil... and it gunked up heavily when the powder residue mixed with it.
 
Walker problem

I got it fixed! I placed a small hard wood dowel between the tips of the bolt and shaped it all up with an exacto knife. Greased it up and put it back together. Works like a champ.

Thanx for all the help. I gained confidence in doing this. Previously I had never taken a gun apart past field stripping it.

Das, more than 50 but less than 100.

Might want to

consider ordering a new one , bolt . Just to have on hand if that one breaks or becomes unrepairable :D
Glad you got it fixed . :D

Jaeger , 75 rounds , its still new :)
 
I took both my Walkers apart when I first got them to clean out metal filings, burrs, & lube it. Man, not gonna do that again unless necessary. Needed padded clamps to get the weird mainspring back in place.
 
Really? I got mine back together fairly easily... the only tool was the screwdriver to seat the screws. That "V" mainspring did take a little dexterity... 'course my big ol' paws may've helped a bit.
 
You guys did

better than me the first time , I broke one of the mainsprings trying to horse it in , umm , I think my new one was $24 at Dixie ? :banghead:
That'll teach me :D ....I finally figured out how to clamp it and tap it up in place at the same time , four hands helps , which is no problem if your an Octopie :D :eek:....Little wonder a couple years later the Dragoon flatspring was born . :D .........It works just fine as it is , but I do appreciate the Flat Springs better , and the instalation of said flat spring better too :D ...I am sure someone has Modded out thier Walker with some other Coil set up though like the Ruger Old Army , but I have yet to see one ? Although I think that would take all the CHARM out of the gun and make the task of complete disassembly much easier :banghead: :neener: .......Funny how pride in hysterically correctness keeps some of us from Evolving past ape-hood :D

You've taken your first big step to becoming a table top gunsmth. It's a requirement if you plan on owning many of these Italian replicas.

Oh yeah! After a while you get to taking pride in showing the skeptics that "it CAN be done" (making C&Bs reliable). Eventually you evolve into finding "deals" (very inexpensive 2nd hand C&Bs) only to discover that there's something majorly wrong with them and taking pride in fixing them up into reliable shooters (or banging your head against the wall of shame for getting SCREWED AGAIN!).

Glad to hear you got it fixed. ALthough I admit I am a addict............. I have to take em all the way apart just to see how they work plus I like em good and clean and well oiled ;)
 
Same problem with an Uberti 1860 Army, bought second-hand but unused. made I believe 2004.
Appears to me the bolt is rising before the hand (pawl) has rotated the cylinder in line with the bore. Gotta move the cyl a little by hand to get it to the right place. Would be hard to do in a match, harder I suspect in a gunfight.

Yeah, thought I'd save money buying a used '60 Army. This will be my Learning-to-Fixit gun. I doanwanna Fixit, would really prefer to just buy a gun that works. Will get a Cimarron Army as soon as I can convince them it is legal to ship caplocks to non-dealers in Beautiful Michigan. Didn't used to be so, but the law/rule actually got changed a year or two ago.

So does anyone know a good gunsmithing book specifically on fixing timing problems with the Colt single action internals?????????????
 
Percussion Pistols and Revolvers, History, Performance and Practical Use by Mike Cumpston and Johnny Bates. Available from Amazon.com. Not to be confused with Percussion Revolvers, A Guide to Their History, Performance and Use, also by Cumpston & Bates. The latter book was their sequel to the first and actually contains more information about other guns. However, the proofread cycle was not properly completed and the authors decided to withdraw it from publication rather than be responsible for an imperfect product. The publisher nonetheless printed several copies which are still on the market.

There is also a good web article on fine tuning the Pietta 1851 Navy which has broad application to all the Colt CW era revolvers.

Send me a PM as soon as you find that new regulation. Perhaps the MCRGO web site can be of some help.
 
Thanks for the great Info

Mykeal , those are a must read for anyone that wants to dabble into the single actions . Just knowing how they are put together and SHOULD run right is a huge step in understanding the design , especailly if your plannin on dabbling into getting the Repros goign better .The Ubertis need littel help , but the Piettas almost always need some .

Thanks , Das Jaeger
