 |

I finally got frustrated enough this weekend to ask a question of
anyone who has a good answer.
For grease guns, I went to the local farm and barn type store
and got a couple of what looked like pretty good guns.
But, while I've had good luck with the grease gun that I use
for my wheel bearings and nose swivel area, which I use a
different grease for, I have HORRIBLE luck with my grease
gun that I use with Aeroshell 6.
The gun that is giving me issues is basically this one:
http://www.mastertectools.net/image_atus/31004.jpg
It's got the loader fitting on top that I never use, and a bleed
pushbutton to purge air.
I tore it all apart this weekend again and it appears that
just a spring pushes the plunger up to force grease up to the top
section where if it enters a hole, squeezing the handle will
push a piston forward and inject the grease.
Stupid simple.
The issue mainly seems to be that Aeroshell 6 is just so
thick that it doesn't flow up into that cavity.
I was able to work around it this weekend by repeatedly
unscrewing the top a few threads, which would help
allow the spring to push grease up, then crank the top
back down on the gun. The added pressure on the grease
made it flow into the orifice and then it would pump.
But, I had to repeat this every pumping.
I'm about to throw this thing out the window. Is there
something I'm missing? (The seal on the plunger does
also seem to seal into the grease tube BTW...it's a
rubber sealed plunger head.)
Or does everyone have a problem with this thick
Aeroshell 6?
If someone has a great grease gun that works real well,
send me a link to it...I'd be happy to just buy one
if it will give me a much more enjoyable greasing
experience.

You need to get all the air out of the upper chamber. Take the hose
off, squeeze the handle and hold it while you put your finger over the
outlet so air doesn't go back in. Repeat as often as necessary. Make
sure there isn't any air space in the hose, put it back on and it should
be OK.
Linn .... lots of foul language at grease guns.

Tim,
I fought the same problem for years - couldn't reliably burp all the air
out of the gun, so it would stop pumping.
Then somebody showed me that it is possible (at least on my gun, I
understand this is a common feature) to turn the plunger handle to just
the right location so it will engage with the grease puck, allowing the
operator to push on the end of the plunger handle and apply extra force
to the grease column. Then you can operate the lever (or use the air
burp fitting, if so equipped) to get a nice air-free column of grease
flowing.
In practice: rotate the plunger handle a little, push on it, see if
there is resistance. If not, turn more and try again. Repeat until the
plunger handle is locked to the grease puck.

Thanks to you guys who replied on my grease gun question.
What I did was this: I purchased a new Lincoln 1134 gun,
that runs about $40. It was reviewed and rated pretty
high and is supposed to have a pretty heavy duty spring.
I definitely could be not getting all the air out of it.
Given that there's a relief button on top, this SHOULD
be pretty easy to do. But I think the root cause of
the issue is that the Aeroshell 6 is just so thick that
the spring isn't enough to get it to flow up into the
gun, even to release air. Being in Wisconsin with
temps in the 30's doesn't help, although I did try
to warm the gun with my heater last week.
Also, I did read your thing, Tim, and after tearing
apart my gun, there definitely wasn't any handle
orientation that was possible on my existing gun.
It was a straight shaft that just slips thru 2
plunger items. One is a backing plate/stem for
the rubber plunger, which keeps the plunger
level, and the other is the rubber plunger itself.
Above that it's just a flat washer and cotter pin.
So nothing that you can twist to make any difference.
The grease isn't slipping past the plunger, either.
So really the only thing that would make the
grease not be burpable is if it were just too thick
for the plunger spring to force upwards. That's why
I just went for a new gun. With the new gun, I'll
burp it out well and see how it works, and report
back. I'll tear it apart first. Maybe I'll even
tear them both apart and show internal photos. If the
new gun works well, it may help others to document it.
My old gun I'll relegate to using a different, less
thick grease, for just doing wheel bearings and
chassis stuff at home.
More to come in a week or so.

Just closing the loop on this grease gun thread...
A couple days ago I received my Lincoln 1134 Heavy Duty Grease
Gun. It seems to be well made, with a nicer plunger than my
old one...not extremely better, but a little nicer. Otherwise,
it really isn't a big change from my old gun. Today I tried to
load my Aeroshell 6 into it and nope, it didn't work either.
Even after purging the air out of it.
So I got irritated and grabbed a brand new tube of Aeroshell 6
even though mine was not even half used. Right away I could
tell that this grease was not as thick as my old grease. It was
vastly different, and much more "oily" if that makes sense.
I cleaned out the old Aeroshell 6 that I tried to load in the
gun and stuck in the fresh tube. That stuff pumped out ok
after purging out the air. So, I probably didn't need to
spend $35 on a new gun...my old one would have worked just
fine. I just had crappy grease. Now I feel a bit bad that
I just shot 6 pumps into each side of my RV-10 prop on that
old grease. Oh well, hopefully it'll work its way around and
still be OK. Maybe after a few hours I'll throw a couple
more pumps in of the new stuff.
For my old gun, I cleaned it out and loaded up a fresh
tube of the grease that I'm using for wheel bearings and
nose swivel. There really aren't too many other places on
the plane that need grease, other than the nose gear
hinge points.
I'll probably put pictures on my website some day of
the guns, but, right now that's back burner for me.
I don't know if Aeroshell 6 goes bad over time, but I'd
encourage you all to make sure that if your gun doesn't
pump it anymore, you just get a fresh tube. I'm not too
happy I even tried to use that old stuff now.

When I leave Aeroshell grease in the gun, the spring pressure causes the oil to run out of the grease, making it drier. Now I always take the handle that keeps pressure against the grease and pull it back and lock it so it takes the pressure off the grease. This helps keep the oil in it so it doesn't dry out and get thicker.
