My grease gun is not a nipple person

[101RRS]

My grease gun goes onto nipples OK but will not let go and when wiggled to make it let go, it gets angry and rips the heads off the poor nipples - meaning the ease out has got to come out to do an extraction.

Any ideas on how to stop my grease gun ripping the heads of poor little nipples. Has done it twice now.

Thanks

adjust the orifice size by rotating the collars on the nozzle.It can look like there are no moveable parts on the nozzle, but there should be.

I had this trouble, then realised I had to clean them first with a rag.

As Crump mentioned the nozzle needs adjusting.Remove and clean it,if it appears damaged buy a new nozzle.
When its clean you will see it adjusts the clamp on the jaws as you twist it,it needs to be set so it clips onto the nipple loosely,if its too tight you get the hydraulic pressure of the grease locking it on as you have found.
Goodluck

what part the nipples or the orifice of the gun, yes it is a serious question

[101RRS]

Hmmm - maybe I need a new end - no adjustment on it - I know what you are taking about but this one don't move - is all clean as it is relatively new as are the nibbles - putting in new UJs on my rear tailshaft and it has eaten both grease nipples :mad:.

Maybe I just buy a new end for the grease gun but not from Super Cheap.

Thanks for the comments

If you've got an el cheepo from Super Chirp or similar then that could well be the problem. Go out and spend the money on a good MacNaught K29 gun. You'll only ever buy one as they last forever and can be rebuilt.

even the cheapys have adjustment on them its part of how they are made.

you might need to use a bit of force to get the head to rotate but they do move.

[LandyAndy]

As what Derek says.
I have the same one,we also use them at work.

Threw the non-adjustable one in the bin and put on an end from an old 50yo gun I have - it is adjustable but must fit a larger nipple as it will not tighten up an just squirted around the nipple. So switched to another old 30yo small gun that did the trick.

Thanks

Are there metric and Imperial nipples?

There are several styles but the common one used on most passenger vehicle applications are a stadard size. They do come in a myriad of threads and lengths though.

I've got one of these and they are great. For something that you should be using quite regularly they are well worth the extra money over a Supercheap version. Only cost around $100.

Another Macnaught product that is good is the 'Suction gun hand operated'
Macnaught Pty Ltd - suction gun <br> hand operated | Macnaught Pty Ltd (http://www.macnaught.com.au/shop/item/suction-gun)
About $55. I always dreaded changing gearbox/diff/transfer oil before I bought one of these.

Possible the nipples are blocked no grease gets through and the pressure that builds up between the grease gun and the nipple can be immense, locking the jaws on the gun. This used to happen a lot on excavators and earth moving gear.

Remove the hose from the grease gun and then try to remove it from the nipple? This should reduce the pressure and allow the release of the jaws on the gun.

Try taking the nipple off and give a few pumps to see if grease comes through, put it back on and try again.

Sometimes the area you are trying to put grease into is packed solid with a mixture of old grease, dust & other crap and will not allow any more in, needs pulling apart and a good clean. Very dry and dusty or mudy or a long time between application of the grease gun can contribute!

If the nipple lets the grease through not attatched to the vehicle but refuses when on the the vehicle might be an indication something not quite right inside whatever your trying to grease.

This used to happen a lot on the excavators and usually required a bit of a pull a part, clean and reassemble and always threw in a new nipple.

Process of elimination.

I have one of those and it is the biggest waste of money out - the plunger does not seal on the body and oil leaks everywhere.

Really?
How long have you had it?
I'd be returning it if you can. Mine is not quite 1 year old I think but has been used a bit and still seals perfectly. In fact the suction is so strong that I find I need to do a slight back and forth twist on the handle as I draw the oil in to make it easier on myself.

Being MacNaught I assume you can rebuild them but the kit would want to be cheap given a new one is $55. It is probably only one or two rubber seals.

I wanted a repair kit for my McNaught Mini-lube. The Qld. distributor did not stock spare parts!!!! They order them in from Melbourne as required and charge you the courier fee. A small clip lock bag of o-rings and seals $14, Courier $15. Product is good but this sort of customer service stinks.

Another Melbourne company is the distributor for a very reputable top shelf make of American pneumatic tools. They are listed in the Brisbane 'phone book as having an office at Acacia Ridge and I used to go there to buy parts.

Couple of years ago I 'phoned first to see if they had stock of my requirements. Took three days to get the 'phone answered. Turns out they no longer have a store there. It is now an office staffed by a part time clerk-typist who does admin work for the southern based reps when they are in Qld. and use the former shop as their base whilst here. I now have to go to a dealer 15 miles away from my place. Not happy, Jan.

Is it a McNaught?

I bought a cheapie and found there is a ridge of weld down the side of the tube where the tube has been rolled and welded. There's no way the plunger washer will ever seal. My McNaught doesn't have that lumpy weld.

[Grimace]

Got two McNaughts, ones almost a thousand years old (about 964 this december), still use it all the time. The other is like brand new (scored it for $20 at a garage sale, BARGAIN!).

They are good, and like mentioned also rebuildable. Have not had to replace anything on my gun ever.

[101RRS]

Is it a McNaught?


Yep - the same as in the link that Utemaid put up. Maybe needs a new seal but has only been used a few times because of the mess it makes.

Look at the number of views this thread has had. I can't believe that grease guns are really all that interesting. Some people must have done a search on one of the words in the title. :p
