<div dir="ltr"><div>Thanks Jim, that makes perfect sense. I was wondering about steering gearbox lubrication. There were no fill, drain or level plugs so I was wondering if it was to receive grease from one of the 3 fittings on the column / gearbox. The manual just ignored any lubrication of the gearbox other than those 3 fittings.</div><div><br></div><div><br></div><div>.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, May 16, 2019 at 10:26 AM Jim Becker <<a href="mailto:mr.jebecker@gmail.com">mr.jebecker@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<div>Farmer,</div>
<div>I know even less about the Case VAC than you do. However, I gleaned
this from looking at a cross sectional view. It appears that the steering
gear is open into the torque tube. That made me wonder how the steering
gear got any lubrication. From a closer look, it appears the main shaft
has an oil slinger directly under the sector gear. If that is the case,
that section needs to have oil in it. Additionally, it is probably fairly
fussy about the proper level. There has to be enough oil to wet the slinger but
not so much that it keeps the oil from being properly slung.</div>
<div> </div>
<div>Again, this is just what I could guess from looking at one diagram.
The service manual, or even a parts catalog should be able to confirm or
refute.</div>

<div>I've had these 2 Case VACs (one running and driving decent and one apart
and not running) for a number of years but have not done much work on
either of them beyond stuff like tire work and superficial things on the running
one.</div>
<div>When it comes down to messing with the innards I'm finding things a little
alien. The engine is of course fairly cut and dried and the owners manual (PDF)
covers it fairly well. At this point the engine of the running one doesn't need
anything but a bit of tweaking in the governor department. No smoke, no noises.
I have a DVD of the parts manual here "someplace" but it has slipped under
something else... I don't have a "service" manual for this one yet.</div>
<div>As I said it is kind of alien to me. Before I bought these two VACs (and a
VAI that I acquired for son Scott) I had never even driven a Case Tractor. My
background was with Fords and Ferguson and Massey Fergusons and Farmalls and
several Allis models etc.</div>
<div>As I understand it there are three compartments behind the engine, the belt
pulley / hydraulic pump section, the torque tube section and the trans-axle
section. Each of the three sections have their own drain plug and fill plug. My
information gap is are all three sections sealed completely from each other or
do the torque and trans-axle share lube. Is there anything in the torque tube
besides the main shaft? I wouldn't think so. On about everything else I have the
main shaft runs in a dry zone. Not sure why this one is wet?<br></div>
<div>The pulley / pump section calls for 10 weight oil, the torque tube calls
for the same thing as the trans-axle.</div>
<div>Maybe it's just been too long of a day... :-)<br></div>
