    EZ-Lube maintanence

    So I've decided to lube my Monty on my own after I observed some questionable techniques that my dealer did. I don't think he did any harm, but he clearly didn't follow Dexter's instructions.

    First I've heard a number of folks talk about just repacking the bearings as if you don't have EZ-Lube. If you're an experienced mechanic I can see this to be a good approach. But I repacked my wheels back when I was a kid and I quickly found out that there is a skill in tightening the bolt holding in the bearings. Too tight is as bad as too loose. So I assume that I have not gotten any better at knowing how tight with 50 years of not repacking bearings.

    So I will use EZ-Lube until something needs to be replaced then I have a Dexter expert rebuild everything.

    I've found a lot of videos on doing the EZ-Lube, but the one thing they don't talk much about is the exact use of the Grease Gun. That's where I had most of my issues.

    My gun is a high end one from NAPA, but it's made in China like all the rest of them regardless of what auto parts store you go to. The instructions said to pull back the plunger until it locks and then put in the open end of the grease tube. Then you pull the pull-tab off and screw the tube barrel back into the pump mechanism. There is a tab at the plunger end that you release to make the plunger compress the grease.

    What I had problems with is that you'd pump it for a while and then the pumping got easy because no grease was coming out. I'd flip that tab again and it's click and it's start pumping grease again. At one point the pumping produced no grease regardless of what I did so I unscrewed the barrel and when it came apart there was a lot of grease still in the gun.

    So I started over with another stick and this time when it got easy to pump and no grease was coming out, I pressed the tab and pushed the plunger and it came all the way in and I thought that meant I was out of grease. BUT when I pumped, grease did come out for a long time. I even finished that wheel and moved to the next one.

    Not sure how the grease gun is supposed to work, but I'm making some progress. I've completed that wheel and mostly finished the second. Now I need more tubes. It seems to take one per wheel to completely flush out all the old grease.

    If you can help with my understanding of gun operation, please jump into the discussion. I'll post some replies with my progress.

    The problem is the rubber plunger not riding up inside the tube. Then you have the grease tube itself, that might not be made correctly. This combination will cause the plunger not put enough pressure inside the tube to force the grease out. The tab your hitting is the air bleeder. I have bought cheap and very expensive guns only to have some issues down the road. My last resort was like you going to NAPA and buying the best gun, only to have issues on and off.

    You might have better luck with using grease that comes in a plastic tube vs cardboard.

    I now own a Dewalt cordless grease gun and don't have those issues anymore. CAUTION - You need to FULLY understand this tool and how it operates or you WILL blow out the Dexter seals. The Dewalt does come with a variable speed trigger that allows for really slow grease flow. The Dewalt so you know, does not push out a continuous flow of grease. It pulses out a one inch stream of grease at a time, much like when you squeeze a hand gun.

    They do not sell them in the store, you must order them online. The only store I've seen to have them is Tractor Supply.

      Hi Jim! I will try to help. I can fully understand this scenario. I grew up on a farm and played in dads grease bucket at six years old. I then progressed to driving a tractor at nine years old. Before each day and ar noon we had to grease everything! Oh....no handy tubes back then......fill that gun out of the 5 gal bucket. Jim ....enough silly. When you pull the tee handle back and engage the slot....pull tab...remove covering on other end. Insert tube....screw barrel into head.....not all the way. This step is to purge air from the gun. Grab the tee handle and allow it to put pressure on the grease in the tube. Try pumping the grease gun....when grease starts you can go ahead and screw the barrel into the head.
      Jim ...you are doing the Dexter method which is what I also do . Have done this on construction /farm trailers forever.
      My Montana is model 2010 and hubs have never been off until a week ago. Over 100,000 miles. By the way my brakes where only 1/3 wear. Installed new brakes.
      My philosophy is the Dexter method......before big trip pump one tube thru each hub. Hope this helps.

        Jim,
        It sounds like you may be getting air in your grease gun. On my grease gun there is a bleeder screw on the end with the hose to let out the trapped air after you release the plunger. Not sure if that is what is happening. I have had the same issue and had to bleed out the air. Just try and slowly back out the screw until you have grease coming out. If the screw gets away from you the grease will quickly exit your gun. Wonder how I know that? Hope this is of some help.

          Thanks for the help guys. I do have a spring loaded button to release air, but I think the problem is the handle not progressing up the tube as I pump. I'll get some more tubed and do the rest of the wheels today.

            One more related question. In looking for tubes with plastic construction, I found Lucas Oil Red "N" Tacky #2 which seems to meet all the specs that Dexter requires, but it's not listed in the Dexter list of approved grease. Anyone every use it? I've emailed Dexter for their comments on the Red "N" Tacky.

              I use Mobile One in the plastic tube. Lucas should be fine. Just so you know, whatever grease you buy, stick with it. Also flush out as much of the old grease as possible. What's in there now is a Lithium base grease and mixing different types of grease together can cause caking or turning the grease into hard clay because they are not compatible with each others base stock.

              I was a member of an oil forum for years and let me tell you some of those guys were scientists for major oil companies. I learned a lot from them. That was before every Tom, Dick and Harry are on now and ruined it as far as I'm concerned.

                Just to close this out. I got it all figured out. The issue was the plunger on the grease gun should be pushed in all the way as soon as you put in a new cartridge/tube of grease. Did 3 wheels today. I only had the pump go "easy" and quit pumping grease once and the air bleed button fixed that.

                I also rewatch the videos on greasing the EZ-Lube and they just keep pumping and let the grease come back out around the pump tube/hose, periodically cleaning off the excess. I ran 1 complete tube of Lucas Oil Red "N" Tacky #2 per wheel. That is suppose to guarantee a complete flush of the old grease.

                Thanks to the LevelUP I just raised up the rig enough to get the wheels to spin and sat there on a stool and spun the tire with one hand and pumped the grease gun with the other. The NAPA gun I used has a hose and the metal nozzle locked on to the grease fitting. They suggest pushing it on at an angle and removing it the same way.

                Just like the Dexter video, I only clean out the hole around the fitting enough to put the protective rubber cap back on.

                Job done; now time for a beer.

                  Hi

                  I find the EZlub system very useful. I am now approaching 100,000 miles on our trailer and have never had to replace a bearing and have never removed them to grease them.
