As the proud owner of a new double (krieghoff .416) I was wondering what people use to lube the hinge pin and locking lugs. On the old parks doubles we used a moly grease that was issued for the F.N. rifles and I still have a small stash- but technology has got to have improved since sanctions ravaged Rhodesia in the 1970's!

Either Mil-Tec grease or STOS.

I suppose any decent grease will work. The two gunmakers I respect the most have recommended white lithium grease.

I would not recomend grease at all. Grease atttracts dust and buggers, and make the grease a paste that in worst scenario can make the fit sloppier. Regular oil, often applied, that is my adwise.

Obviously not a double gun pro. Oil won't stay in place and lubricate. It will run into the action and thence into the stock head, softening the wood over time, a very expensive problem with fine double guns. Grease, never oil.

No, I am not specialized in double guns.
But I do work a lot with double shotguns.
And I see how people use them.
And I would never apply so much oil that it could run.

It's like my niegbour's new car. He was concerned about the paint, so he did not go to the car-washer-mashin - because it would ruin the paint.

Ended up not washing it at all, never had time to wash it by hands.

So what do you think damaged the paint the most?

I use the Tetra grease - very similar to white lithium, it is a synthetic blend that works great.

Guys,
I'm not trying to be a smart-ass, as I am avare that many of You guys work a lot with doubles - or shoot them - and I am sure that grease is "the right thing to use".

It's just that I have seen many guns ruined by eccessive use of grease - just like .400NE have seen doubles ruined by to much oil.

This subject came up on another forum. Below is a logical response to the same question.

quote:
My career spanned over three decades with a major oil company with responsibilities for major million dollar equipment and the correct lubrication of such.

The EP you mentioned means "extreme pressure". This is what you want on a hinge pin as it is a VERY HEAVILY LOADED part upon firing. One needs film strength here for the best of wear/shockload capabilities.

It matters not whether the lube is snow white with "purity" or smells of the essense of rose or even what someone (including gun manufacturers) necessarily passes on as good.

E.P. lubricants worth their salt have a test in the manufacturer's lab called "Timken O.K. load" The number will be in pounds. 50 is good but 70 is way better and few lubes reach 70. That is what I use a NLGI #1 grease E.P. with a Timken O.K. load of 70 or more.......... This will buy you all the lubrication and protection a lubricant can provide.

One should stay away from light oils as hinge pin replacement is not cheap, and that is where the no-shock load capability oils will take you.....

Some of the newer Auto trans fluid have some E.P. additives but not to the numbers mentioned above. If I just had to have oil I would use one of these.


quote:

The hinge pin seems to wipe all lube away, but a thin film stays with a quality EP lubricant. Just a few thousandths of an inch or even less........ What we want to prevent is metal to metal contact! Oil will not do this adequately; especially light viscosity oil. Even more for our case is the angular, even torsional load the hinge pin sees in a side x side double firing first one barrel than the other. This has a tendency to "wallow" the pin fit rather than wear it evenly. We are talking clearance amounts one may see or not see with the naked eye. But a good E.P. will protect these high load spots. That is what our goal is!

Some greases are better than others for "staying put" or remaining where you want them, where the action is.

I have a rather un-scientific test for this "clinging" ability. Stick a finger into the grease a quarter inch or so. Pull away from the grease slowly and the grease should try to "string out" from the container to your finger.

The best I have seen in this "clinging test" is a Chevron product called "Ultra-Duty EP" It is red in color and I have had it "string out" three feet or more in little red threads of grease! Chevron advertises that it "stays where you put it". I will say this is a true statement.

Not only that, it has a Timken O.K. load of 70 . . . . .

The forces on hinge pins is high and there is a 'wipe away' factor [as you find in hypoid gears too].There are lubes specifically designed for this and good for older stainless steel guns to prevent galling. One designed for this I use is RIG+P+ for my O/U shotguns.Can't offhand remember other lubes designed for this.

New Guy (Chris) recommended to me a Timken 80 red grease and so I did some searching. Many auto parts stores sell an EP red grease and they typically top out about 50-60 Timken scale.

The best I've found (and use on my shotguns now and soon to be Heym) is:

Sta-Plex EP premium red grease from CRC Stay-Lube. It has a true Timken 80 rating and exceeds the others in every other rating category. It can be bought over the web and sells for about $5.00 per pound.

A second on the Tetra.....it seems to stay on well and didn't gunk up with dirt or other buggers on my trip to Africa. I put it liberally on the hinge pin.

Thanks for the input. Will try and get some of the good stuff, as I have 500 cast bullets that need shooting in the next couple of months to get me fully familiar with the rifle!

One of the guys who recommended white lithium grease to me was Cyril Adams, author of "Lock, Stock, and Barrel". He got the recommendation from Timken Bearing, back when he was owner/managing director of Atkin, Grant, & Lang, the London gunmakers. Timken had studied every lubricant under the sun in various applications and had found that white lithium was superior to other lubricants in ambient applications (as opposed to hi-speed/hi-temp). They said it bonds to the grain of the steel and stays there until removed with a solvent.

Any lubricant can turn into a filthy muck if it isn't changed periodically, but that's just neglect and no argument against using the right kind. The grease needs to be removed with solvent and replaced from time to time. Oil can't stay in place and do the job.

I agree with mete. I have used RIG on my O/U skeet guns forever. I have continued to use RIG on my double rifles. I believe that RIG and STOS are very similar.

does anyone know or have access to the tech specs on Tetra-Gun ?? I've looked but can't find anything. I'm going to stick with the Sta-Plex unless Tetra publishes any kind of data to judge it by.

(Not meaning at all to cause a stir, it just bothers me that a company will market a product for a specific use but not publish any data on standardized tests to back it up. Is it Timken 20, Timken 80, what??)

I also noticed they do not publish a timken rating. The reasons I migrated to Tetra were (1) the operating temperature range of -100 to 750 degrees F and (2) the fact that you can use very little to achieve the effects, thus reducing the chance of fouling. You can basically apply it and wipe it "dry".

I sent Tetra a request for the timken rating. Will let you know what I hear.

Looking through some websites it seems that "white grease" may be lithium stearate, teflon or some others. Make sure you know what you're getting . I'll stick to the RIG+P+ which I think is RIG with an EP additive.

The best high pressure grease/lube I have used is made by CMD, their lubes have shown me that they have tremendous film strength and lasting lubrication with "stay put" properties. Their lubes are specified for machine work and go through much higher pressures than the hinge pin of a firearm.

Heres another one for Tetra. It works better than anything else that I have used. However I think that the biggest danger to lubing a double is the case. Most people will wipe all the lube off the lumps when putting the barrels into the case. If they dont wipe it off, the case will do it for you. The lumps need to be lubed every time before assembly. Any lube is better than no lube. Wink

Hi Mouse

Yup a 500/.416 NE, replacement for the H&H .404, the C&H .404 and My .458 Lott and several other rifles I have owned and never shot anything with! I will stick to my 9,3 for normal hunting and switch to the double for any follow-up's (however, I have my eye's on a nice 9,3x74R at the right price, or will buy some spare barrels in 9,3 and 20g for the krighoff as and hen I can afford them)

From Manual Krieghoff recommends "Krieghoff Gun Glide" - they would charge you $6.50 for a 1 oz. Krieghoff store

no kidding, that town is 10 miles from me, you can almost spit from one end to the other. Didn't know anything existed there.

I'll have to give them a buzz and see if I can stop in sometime.

Krieghoff "Gun Glide"!

This stuff has excellent surface adheasion, does not deteriorate when heated-up and is almost colorless (has just enough pigment to allow you to see where the coverage is when applied).

I use it on all of my bolt and double guns. I have tried'em all!

Another user of Tetra grease, this grease does a fine job with a very thin coat and stays put. Ganyana, if you can't find any in Zim. I would use the white lithium grease. If you know someone headed your direction from the States I'll send them a couple of tubes to give to you, let me know.
