hydraulic oil in the old fords

[ky wonder]

i have a 961 and want to change the fluids will regular hyd fluid work in these systems, or do i need to mix olils??

You should use either Ford spec 134-d or universal tractor fluid. I use UTF in all three compartments, transmission, hydraulic and differentials so that if the seals should decide to leak between compartments then it's not harm no foul. UTF is safe for all three.

if you put hyd oil in your sumps you will soon need a transmission, differential, and final drives.. though the 3pt lift will be fine!

utf in all the sumps, or utf in the hyds, and gear oil in the rest.

my question is unrelated to this model but is sort of on the same subject.

i am changing fluids in my neighbors 1974 ford 4000 model tractor. i am still trying to fill the rear differential. How much does this thing hold? I can't find anything on the internet about the fluid capacities of this tractor.
Am I suppose to fill it until the differential carrier is submerged in fluid?

I filled the transmission until fluid drained from the high point plug on the side of the transmission so I think I got that one right.

i have an 801 series tractor which is essentially an older version of the 4000, and my manual states that the rear axle takes 11 quarts of mild extreme pressure lubricant, SAE 80. It also states that there is an "oil level plug on side of housing".

hope that helps

on this tractor, i cannot find an oil level plug anywhere on the side of the axle. this tractor is supposedly an industrial model. its painted construction yellow and seems to have more features than the average agricultural tractor.

when i drained it, it had way more than 11 quarts of fluid. its also one of those wet brake axles. im lost when it comes to servicing equipment like this.

The specs for my '73 4000 says 34 quarts for the rear end, which is 8.5 gallons. The 801 is essentially an older version of the '62-'64 4 cylinder 4000 tractor. the newer '65-'75 4000's were entirely different, with 3 cylinder engines and completely different rear ends and rear axles.

The fill plug is on top of the differential housing. You should have a level plug on the right side of the center housing in front of the axle.

your 4 cyl 4000 shares almost nothing in common with a newer 3 cyl 4000, except the name of the manufacturer, and a few minor parts. It would share much with a 4 cyl 4000 from 63-64 though.. virtually same tractor.

the newer post 65 3 cyl's were just completely different animals.

So filling the rear axle is a matter of measuring the fluid going in?

After thoroughly searching, the only level plug I have found is for the transmission.

There should be a level check plug on the side of the differential housing in front of the rear axle. I'll try to scan a picture form my manual, but it won't be until I get home this evening. Which leads to the usual recommendation around here... You should purchase a manual.

Sorry I haven't had a chance to post any pics for you on the location of the rear end fluid level check plug. I've been swamped with work.

Anyway, I got a quick chance to look at my tractor this morning before I left for work (it was actually light out when I left for work finally). The level check plug for the rear end/differential/hydraulics is on the right side of the center housing, in front of the right axle, just behind & below your right heel when you're sitting on the tractor. If things slow down I might even get to post a picture for you soon.

that would be nice if u could!

maybe paint the plug with some pink nail polish for dramatic effect

A PINK fill / drain plug on a tractor? Where is Mr. Pinky when you need him? (just kidding)
