I just got a set of Wolff springs for my Ultra II. In looking at the rod, I cannot see a very clear way to get the old smaller spring off of the rod under the larger spring. Can someone enlighten me as to how this is done? Of course the Wolff material says that it need proffessional changing.

Jess,

I was hoping that someone else would chime in, guess not. The best source would be to do a search on this forum. I found many posts dealing with this. I have not done mine, but will, soon.

It basically involves unscrewing the assembly. It is probably loctited in, and should be re-loctited upon reassembly. You will have to secure at least one end in a vise, with propper padding so as to ding up the metal. I am guessing that you need to secure the back, and turn the front. I will try inserting a stiff allen wrench into the front hole then heat, then try turning. I am a little leary about trying to grip and turn the front of the rod from the round stop. I might have to. What I would highly suggest that you do, as I did, is order a spare from Kimber, so if you bugger it up, you will not be out of action. Kimber told me that they use a special jig. Unless your "professional" is a Kimber specialist, I suspect that they will end up doing what you or I might.

Again, I have not done mine, yet, so please try the search first. I have only described what I have read and interperated, and YMMV.

Ultra recoil spring replacement

It's not hard at all but you should use a vise and red loctite. I'll post the process when I get home tonight.

Thanks for the answers. I will stand by for more information. What do you think about chaging to the 21 lb spring?

Everytime I try to do a search, I keep getting the error that I don't have the minimum of 3 words for the search even though I do. I have never been able to get the search to work.

I asked this same question of Kimber - - especially since the manual says on page 35, "The Custom Shop will replace both springs if you send in the complete assembly to Yonkers, however the double spring assembly is normally replaced as a complete unit." To me, that says that Kimber expects you to chuck the whole recoil assembly every 1800 rounds and replace it with another $39.95 assembly-- or send it in to Yonkers for a rebuild for $19.95.

I asked Kimber's tech support if the recoil assembly was operator rebuildable. Kimber's tech support told me that the outer spring only needs replacing at the recommended interval (1800 rounds per the manual). When I advised them that this was contrary to what they had printed in the manual and asked for detailed instructions on how to disassemble and rebuild the unit completely, they never responded to the email. So if Kimber is reading, how about jumping in and answering this question for us.

I just replaced the larger recoil psring from the set from Wolff. Hand cycled the slide and it felt gritty and rough. Much stiffer. Installed the stock larger spring again and everything is smooth and nice again. What do you think? And no, I did not put the spring in backwards :).

be careful if like the Sa Champion I found from Wolff that the single spring they sell is for SINGLE system recoil s.. infact it is a totally different spring for the two spring setups. on mine the outer spring is about 1 inch shorter then the original in the SA

REcoil Spring replacement

I made a mistake on my earlier post. Use blue loctite, not red!

I have replaced the recoil springs on my Ultra CDP's and Ultra Ten with the Wolff Extra Power 21 lb with no problems. Anyway, here's the steps to follow:

Assuming the assembly is removed and sitting in your hand, squeeze the recoil spring plug and remove the take-down tool then carefully release spring pressure and remove recoil spring plug...You can then slide the outer spring off the guide rod bushing...may be a little tight...might have to twist it off...The inner spring is still captured between the guide rod and the guide rod bushing..Sooo...Find a vise (padded or use a couple of blocks of wood), Push down on the tombstone looking flange (doesn't have a name but this is the part on the end of the guide rod that pushes against the lower barrel lugs)...until the other end (barrel end) of the guide rod sticks out enough the fasten in the vice...Now you can unscrew the flange with padded jaw pliers...The inner spring now slides easily off the rod...Slide your new inner spring on...Put a dab of blue loctite on the rod threads (Mandatory...You must do this)...Thread the flange back on...Don't over tighten...Might snap off...Remove from vice, slide outer spring on...Put recoil spring plug back on...push it down and recapture assembly with take down tool...

Notes: Don't get your springs backward...Don't use red loctite, it’s almost permanent...Kimber uses the blue. Keep in mind the inner spring is pushing against the flange so when you unscrew it...Sproing!!!!...Will launch into low earth orbit if you are not careful....Good luck..

Thanks for the info. I will give it a try. Yes this is a new product for them and includes the inner and outer springs. Also came with a new firing pin spring, but I have not ventured to detail strip the ultra yet. I will install it when I get brave enough to do that. I did try putting the outer spring in, which is MUCH stiffer than the original (gun has about 5-600 rounds through it) and the cycling of the slide was much rougher. Almost felt gritty besides stiffer. Not sure now that I want to run the Wolff extra power springs.

It sounds like the 19.95 refurb is the way to go;)
