[AT] Gear case oil, PTO shaft issues

[Dean Vinson]

Hi guys, good thoughts--I'd been wondering whether I'd see water when I
first started to drain it, but hadn't considered that there could be that
much.  The first stuff that came out wasn't plain water, but it was
certainly more brown and frothy than the rest of it.  It'd only been a week
or so since I last drove the tractor around so I guess it could still be
pretty well churned together.

Anyway, having drained the oil I pulled the PTO housing off the tractor and
fiddled with it a bit.  Just manually pulling on the shifter tube will slide
it along the PTO shaft maybe half or five-eighths of an inch, which looks to
me like it's the intended amount of mesh with the transmission shaft, with a
nice little thunk at each end of its range.  But if I lift the PTO lever, it
only makes that shifter tube slide maybe a quarter of an inch, if that.
There's some slop in the linkage between the external PTO lever and the
inner little arm that actually moves the shifter tube.  Need some more time
and daylight to look into that.

I also noticed that having the PTO housing off the tractor will make it easy
to clean out the goopy sludge at the bottom of the transmission case, but
that task didn't make my to-do list for tonight either.

Dean VP,

I was thinking the same thing.  I drained the backend of a Farmall H a few
years back that had been setting for a couple of weeks and when I removed
the drain plug there must have been at least two or three gallons of "pure
water" before the lube started to drain.

If Ohio Dean's M did have water in it and if it had been running around
shortly before being drained then I imagine that the water and lube would
have sort of pseudo-mixed together resulting in a light muddy brown oily
substance.

Ohio Dean if you still have the residue you might let it sit for a few days
and then see if there is water on the bottom.

Dean:

I suspect you had at least 5 gallons of water in with the oil.

Time to pull the PTO housing off my 1950 M Farmall and see if I can figure
out why the engagement lever won't move.  Operator's manual says the
capacity of the transmission and differential case is 13 gallons.  I just
drained 18 out of there... had to scramble around to find something to put
it all in.  I can see there being a little more than the book number, but
five gallons more??
