IH 444 hydraulic reservoir cover

I have 2 IH 444 gas tractors when I take the top cover off the hydraulic reservoir their is a 5 inch long metal welded to the bottom of the cover and a 2 inch diameter metal welded to the end of that. what is the prepose of it.

I'm GUESSING what you wrote makes sense to you, but for the rest of us could you elaborate a bit?

When those tractors left the factory with live hydraulics from a ''stinger'' pump driven off of the front of the crankshaft to power an industrial loader and/or backhoe they did things like that to adapt the reservoir to make it all work.

Hello Larry welcome to YT! Does it look like anything in
this diagram I have linked? It could be that at one point
your tractor had a front crankshaft driven pump as
wore out posted, now it has been removed. That
probably is where that pump drew its supply oil. I only
guess this because if there were connections to it that
would make its purpose more evident. I really have
very little experience with the IH utility tractors. FYI
you can navigate to all the parts sections for your
tractor from that link. Click on the description of your
tractor to the right of the Home icon at the upper left,
then you will see all the parts sections. On a phone you
will have to turn it sideways to see this. I will also warn
you that the CNHI site does not work very well on
phones at least that is my experience an iPhone.

A picture would help identify the part.
Were your 444s painted yellow indicating they were for non agricultural use?
One of the problems with this IH series of UK Bradford built tractors is that the original design was in the mid 1950s when the only hydraulics were 3pt hitch, front end loader and maybe a single remote cylinder,
so the capacity of the hydraulic reservoir was only about 3 US gallons. Moving forward 10 years and the requirements for hydraulics began much greater and a much larger hydraulic reservoir, on this series of
tractors the solution designed by IH was to use the transmission and differential as a hydraulic reservoir. To accomplish this change in design, the trans/diff gear oil was replaced by IH Hytran and two holes were
drilled in the bottom of the hydraulic reservoir into the trans/diff case with tubes going into the trans/diff case. One tube was the suction line and the other was the overflow line from the original hydraulic
reservoir, next the cover of the hydraulic reservoir under the seat was modified with two tubes, one as the suction line to fit into the suction line in the trans/diff case and the other was the return line. This
is the top cover that the previous poster gave the link to on the caseih.com parts page. Also as the other poster referred too is this configuration usually used an auxiliary hydraulic pump mounted on the front of
the tractor and run from the front crankshaft pulley. Tractors built with this hydraulic configuration were usually used in the industrial market with loaders and backhoes and sometimes for city or golf course uses
where there were side mounted mowers etc, these tractors were usually painted yellow where as ag tractors were traditional red/white.
A couple years ago a poster on this site had a read/white tractor with that hydraulic setup that had originally been used on a vineyard farm.

Hope this helps and I did not add confuse you
