[AT] ford 800 vs 600 steering arm / bellhousing clearance

[Francis Robinson]

	Hi Chris:

	I am only familiar with those one-arm loaders from a distance but I don't
think gaining a little clearance would be a problem. Our NAA was pretty much
all original but we had a "TO" Ferguson that had a Sherman "over/std/under"
gearbox installed in its tranny by the dealer. The dealer had bent the right
side steering box arm out and then back down to gain about an inch and a
half of clearance for the shift lever to swing out. The shift pattern was
like a small upside down "h" and under-drive was out and up. I don't know if
they bent it hot or cold but when we restored that tractor maybe around 1970
the unit had been taken out for some years and we bent the arm back into
shape cold using a ridged conduit bender (heavy wall not thin wall) and it
took the bending fine. We were surprised how soft it was.
	I don't think I would worry much about a tractor of that vintage having
that level of oil pressure. As long as there IS always oil pressure that is
usually plenty. My old 40's Chevy truck IIRC had a factory spec of 15 psi.
Like you, I do like all the pressure I can get but that gauge could be off
or maybe the relief valve spring is tired. Of course I'm sure you have
already considered both of those possibilities. It would be interesting to
see it after an oil change with some premium oil. I guess you will have to
buy it to find out...   ;-)

If you cut a tree plant at least two to replace it...

I've bene looking at an 850 down the road, and thinking about getting it to
hang a spare ford 711 1-arm loader on.

At issue is the clearance between the steering draglink and the bellhousing
behind the starter, where a loader bracket will go.

On my 660 there is about 1.5" of clearance between the arm and the
bellhousing... ont his 850.. there is about 1/2 " of clearance.. thusmaking
the arm rub the bracket.

At first i thought the 850 had a narrowed axle.. but now that i drove over
to see it again.. it's fronts are almost inline with the rears.. just like
my 660.. except that draglink clearance issue... it's puzzling.... does the
8xx have a bigger bellhousing than the 6xx? ( both are a 5spd.. etc.. )

I guess I can wident he axle onthe 850 for some clearance.. or cut and weld
a piece of bar stock into the draglink to make clearance for the bracket..
but.. I'm just puzzled at the clearance differences.

Pitman arms and steering arm from the box look oem.. not bend or welded up
on either unit.

On another note.. the 850 starts easilly.. idles ok, and has 30 psi op at
mid throttle.. about 20 at idle.

I had hoped for higher oil pressure.. like my naa and 660 have ( 35-55 )..
but then.. This guy may have 10x30 oil in the sump too.. instead of the 30w
I run.. etc.. may be old oil as well.

Though I'm not familiar with the 172 engines.. I'd guess they have the same
lube internals as the 134's.. etc.

Brakes good.. radiator has some old solder repairs.. but looks like it holds
water fine. No disturbing leaks.. and no water int he engine or hyd oil..
etc..

steering is good.. no slack..

comments welcome.

If anyone has both an 800 and 600 they can go look at.. I'd greatly
appreciate you checking the clearance from the steering draglink rod to the
boss ont he bellhousing with the 2 threaded holes in it, just aft of the
starter, where a bracket could bolt to... and then compair to the other unit
/ post info.

Anyone else got hundred series with oil pressure numbers in that range?
