The Stovebolt Site Forums The Shop Area The Tool Chest Grease guns

My 35 year old grease gun has really started to leak oil (I guess its the grease that has come out of suspension maybe?) out the back end when I am pumping grease out the front. It has always leaked some, but just a little during storage. But yesterday I was trying to do my annual grease job and I had to keep a rag under it at all times to keep the oil off the floor. My questions are, is this related to the age of the gun and it is time to replace/repair? Can it be repaired? Is it the type of grease maybe? Or is it just the loose nut on the end of the handle? This is the only grease gun I have ever owned, so I have no experience with others to rely on.

Thanks, Lee.

Years ago I had one fail and I discovered just about a month ago you can repair them. The rubber o-shaped doughnut thing in there goes bad. First, you may have to grind off the pieces holding the inner washer/rubber doughnut thing in place. I did. Once you get it off, thread the rod for a 3/8" nut. Then take the top of your grease cartridge (the nylon plastic top) off and carefully and slowly cut the overhanging part off...you want to cut the top so it has the same diameter as the inside of your grease cartridge. This is not as easy as it sounds. Take your time. Then when that is done, cut a hole in the center about 3/8" diameter. There is a metal bonnet over your rubber doughnut. Re-use it. Mount the top thing you just cut upside down...you want it to catch the grease and push it up. You'll see what I mean when you do this...one way will let the grease get pushed past easily and the other way will sort of catch the grease as it goes up. Bolt it down and now...the important part...you will forever have to install your grease cartridge in upside down. You won't be able to push the new thing you made past the metal piece, but it will go nicely into the end that you took the top off of. I don't know how long this repair will last, but I didn't have to discard a perfectly good grease gun. Supposedly there is a place in Taiwan that makes a replacement rubber piece for these but I have not bought one. Good luck.

Thanks Jon, when this one empties I’ll open it up and see what I can do. Maybe compare it to the insides of new ones too.

Iffin your not feeling like putting too much in to it, grease guns are relatively cheap. Usually less than 20 bucks. Even the ones with the whip hose.

its that hot texas weather makes your grease gun slobber

Jon G, I have several types of grease guns but my favorite one came with a 1954 Allis Chalmers WD-45. My Dad had it for years, he was a AC dealer. Painted Allis C. orange. However it has a small factory drilled hole between the handle hinge and grease tube. When using it it pushes a slow stream of grease out about the size of a pencil lead it also has a grease fitting so it can be filled from a high pressure shop gun. When not in use I have to pull the pressure rod out and lock it in the slot. I have not opened it up yet because it is full of grease. What should I see inside. I may have to clean it off and use it as a wall hanger, it's a sentimental thing with me, I don't want to trash it. I remember watching Dad using it at his first small dealership. That was before the days that he could afford the 35 gallon drum with a pressurized pump. Doc

My old grease gun failed and I pitched it. I was really tired of the 'slobber' too. I purchased a new grease gun from NAPA. I've placed all my grease tubes and the gun in a five-gallon plastic bucket that is stored in the basement in a cool environment. Hopefully, no more 'slobber'..........

HandyAndy, great advice for Florida. The new house we are building is 267' above sea level in N.FL. I f we dig down 4 feet here in Central Florida we get water. It will also make a good fruit and canned jars storage. Just have to notify architect. Doc
