AGSCO Building Fix-
Replacement Track Door
Oh dear, opening these old steel AGSCO building doors is
really getting to be an ordeal when replacement parts are
no longer available!
Both of our parents had these red color end AGSCO Quonset
buildings erected back in the 50's and 60's, and they have passed
the test of time. They are still standing and sheltering farm
equipment, and having done so, well over 60 years. Trouble is, the
door rollers only last so long and they need to be replaced. We
used to be able to locate a roller made in Sterling, IL, but now that
is no longer available. But in 2014, after hunting the internet, and
ordering one for trying, we have found a suitable substitute that
will do the job. So, we are posting the info on this page to help
other AGSCO steel building users to fix their doors too.
What we found that works, is the Battalion 4PE56 Door Track
Hanger. It is made in China, not the good old USA type, but will do
the trick to get your doors happily rolling freely again, for as long as
rollers made in China will last.
What you do if you want to replace the rollers for two doors, is
order 4 of them. Google these keywords: "Battalion 4PE56
Hanger", and search for your best price with the shipping costs.
We even seen them listed on eBay one time.
What you will get is a 4 wheel roller with a hanger loop, a pin, a
bracket for a wood door with carriage bolts. You can discard all the
hardware except for the 4 wheel roller with hanger loop. The
hanger loop is to wide, but if you grind off about 1/8" inch on both
sides as shown in the pictures below and use the pin from the
original hanger loop from the door, it will work with your AGSCO
This is what Battalion 4PE56 Door
Track Hanger looks like:
This (in red) is what you can
discard or put to some other use:
In the this image we show (marked in green) what to mark with a
black marker to grind away so it will fit your AGSCO door, make
the mark about 1/8"
wide from the edge on
both sides up a little
ways from the round
part of the pin loops,
then put a grip hold on
the hang loop in your
shop vise and grind
away the black area you
drew on the hanger.
You want to grind
evenly on both sides, as this loop swivels, and you want your door
to hang balanced on it. When done grinding, take a round file and
file off the burrs. You may want to put a little paint on the hanger
part you ground down, to help retard rust
Then get to the hard part and replace the rollers on your door.
This is a two person job at least. That is where a good loader
tractor comes in handy, besides some good help. Pick a day that
is not very windy, as you don't want your doors getting kite like.
You don't want to have to struggle with the wind to keep the
door up right.
You DO NOT have to completely remove your AGSCO
door off and away from the track, unless you want
to take it down for welding or other repair work.
On ours, what worked is pull the door full open position first,
then position the loader bucket to work height, having someone
with a little muscle on the loader bucket up in the air to pull the
door hanging pins out. Don't lose the pins, you will need them to
re-hang the door. That person needs to also be able to reach the
end of the track too from the bucket. Pliers, adjustable wrenches,
claw hammer, screw driver, magnet (in case something is
dropped in grass), might be handy tools to have with in the
loader bucket. A good ladder can also be used to help get in and
out of the bucket should you need to go back to the shop for
some adjustments or parts. You'll need to leave the loader to
help support the door should it tip, especially if you need to go
to the shop for whatever reasons.
Have someone on the ground you can trust to use a block of
wood for a pivot and a long crowbar or pry bar to use as a lever
to raise the door slightly at the roller end you are working on, to
get the weight of the door off the pin, so the pin can be pulled. A
needle nose pliers might be handy to pull the pin out, and put it
back in later.
Note: the person on the ground has to have a study hand lifting
the door, and pay attention to directions, so the person up by
the roller does not get pinched fingers. Tell the person on the
ground if you need the door raised a half inch or about what
amount, so they can try to avoid over raising the door and
pinching your fingers. The person up by roller should use a pliers
whenever possible. Pull the pin (likely need to remove a cotter
pin first), then go to the other roller and do the same. The loader
bucket should be close enough to almost touch the door should
Then, move both old rollers inside the track, over to the open
end (you may have to remove a stop bolt there) to remove old
rollers from the track. Roll in your two new replacement rollers
and roll them back into position over the door hanger loops. Get
your person on the ground to carefully raise up the door again to
the height of the hanger, so you can reinsert the hanging pin. Do
the same for the second roller. Put your stop bolt back in at the
end of the track which may also require a cotter pin. And you can
be happy again with a freely rolling door for as long as the
replacement from China lasts.
We hope this page helps a few fellow AGSCO building owners
out. That is why we posted it. If you wish to make a comment,
