Ford 3000 hydraulics

[Monro]

I have a Ford 3000 gas tractor and believe the hydraulic and axle fluid is running into the gear box. I seen an old post that said this was possible.
Can anyone shed some light on this? Do I need to take the tractor apart to correct it? Evidently you can still drive and brushhog with it this way.
thanks

:welcome: to the forum. Perhaps I'm misreading your question, but on most tractors the transmission (gear box?), rear axle, and hydraulic system all use the same reservoir for lubrication. So, I certainly "hope" hydraulic fluid is getting to the gear box. Tractordata.com shows it holds 6.3 gallons which is about normal for that size machine. That lubes the gears, rear axle, reduction gears, AND is the reservoir for the lift and other hydraulic componenbts.

Thanks for replying Fawken. Your info makes me relax a little. I have ordered a manual for this tractor but I thought there were seals separating the tractor rear end/hydraulics and the transmission box due to having separate fills and separate level check plugs.

When I checked the level in the transmission box oil just squirted out the hole and I caught about 2 gallons in a clean bucket before it slowed down. no oil was coming out of the axle check hole. I would think the level would have been the same at both check holes? Tractor was not running and is on level surface I appreciate any thoughts on this. Thanks

If possible, take pictures of where these check holes are. But to my knowledge the three components are all connected. Hence they hold nearly 6 and a half gallons of fluid.

I have a 93 3930. Not sure if the 3000 is the same. Mine uses the same fluid in the diff and gear box but is filled separately. Gear box is filled and checked by the gear shift. Diff has it's own dipstick and is filled at the top of the diff on either side of the seat.

I also have an old 3000 gas. The transmission and rear axle have separate fill locations. I’m not positive they don’t share anything, but I know they have their own fill and check locations. I can read through my tech manual tonight and make sure I’m telling you correctly, as my memory isn’t always to be trusted. But having that much fluid in the rear axle doesn’t make sense.

 

[Fawken]

Maybe he's got a clogged vent or the system is overfilled. I looked at the drawings on the New Holland Parts look-up site, and like most tractors this model has the transmission case and the rear axle case connected with a clear pathway for oil to circulate. The design is such that they may have felt the need for a separate fill and dipstick in the rear axle housing to prevent a low oil condition on initial fill or re-fill after draining.

Thank fellas for not giving up on me. I got the manual I ordered today and it is worthless and don't show the section I need. If the hyd, axle and transmission share the same fluid it shouldn't have unequal pressure. Like you said Fawken maybe there is a vent or something. My computer will not let met download a picture from my camera right now. Soundman had a picture of this same tractor showing the two
check holes on the tractor that I looked at yesterday but I think he posted it in 2013. I'll see if I can find it again. The two check holes are on the right side of the tractor as your sitting in the seat, the transmission hole is right below the brake and then the hyd/axle is to the left of it toward the diff. I am pretty sure this is a1967 3000. I 'm still looking for the problem.

I just refreshed my sump oil day before yesterday. I have a '65 3000D with the 8 sp. Live PTO. The hyd-diff take 6 gallons. The tranny 2.5 per the manual. Guess what. The manual is correct. Back in the days of the predecessor, the 4 cyl tractors like my 2000D 4 cyl with a tranny drive PTO and 4 speed, per comments from Soundguy I found out and realized that my to and from lines linking my hyd. pump to the 3 pt went through the bottom of the tranny case. Pinholes were the norm and apparently my 2000 has a pin hole or two as periodically, rather than add oil, I drain it down to the fill screw located half way up on the right side.

So for anybody wondering if a tranny designed for 90W GL-1 mineral oil will operate just as good if not smoother in the winter on Ford 134A, yes it will. Mine's been doing it for over 10 years and who knows before that as I bought it (them) about 10 years ago and this is the first time I changed the lube on both tractors. No I'm not referring to engine oil.

Also for your 3000 it all runs on 134A or more commonly sold as JD 303....that's what WM's oil of the era had on the label. But on buckets of the "period" lube, you'll find both specks on the back of the same container. This is not the premium oil required for todays tractors with all the hyd operated functionality, but it was made for that era tractor. It runs a few dollars a pail cheaper than the premium.

Just below the brake pedal, half way down the housing is the tranny full screw. You unscrew it and fill till fluid runs out....same with the other I mentioned next. The fill hole is adjacent to the gear shift levers. At about the same height, back just before you get to the rear housing is the full screw for the hyd-diff. The fill hole is also on the right on the top rear of the ring gear housing. Looking at the center of the housing from behind the tractor on top, and just to the right of the rear of the seat, you can't miss it. And the guy's handle is Soundguy. He's probably got 2 dozen Fords.

Texasmark thanks for the info, I vaguely remember the post that soundguy sent you but I've slept since then it didn't register because he was talking about your 2000 4cyl. Are you saying the 3000 tractor hyd lines also run through the transmission also and are probably leaking like your 2000?

 

[City Farmer]

Your 3000 does not have a common reservoir. There are 2 different fill spots, one for the trans and one for the rear diff. Your hydraulic pump pulls its fluid from the rear diff. and there's no way for the pressurized or return pump fluid to get into the tran's from a hydraulic leak. If it was my machine, I'd watch it for a while before splitting and repairing. Measure the difference in fluid and add it to the list of monthly(or whenever) checks. My dozer takes GL-1 in the rear diff. and I couldn't imagine trying to operate your 3ph with 90wt oil in the winter.

Thanks City Farmer for the info but -
I can fill the hyd/axle side and run the lift up and down and the fluid moves into my transmission. The fluid suggested for use is the same in both hyd and tran -Mc277-A. so that isn't a problem but there must be hyd tubes or something leaking like Texasmark said.
I'm still trying figure how big a problem this is and how to solve it since the manual I ordered on it worthless.
thanks for the info.

 

[City Farmer]

Yes, I run the same fluid in the trans and rear diff also. My mistake, I mis-read a previous post. I thought he put GL-1 in the rear diff but he puts it in the trans. There are no hydraulic lines, tubes or anything else connected between the rear diff and trans. It has to be a seal, loose screw, gasket, etc? . Here's a picture of the sump.

 

[MitchellB]

I know my 58 861D is older than yours, but mine has 3 separate reservoirs, divided by seals in the shafts. I use 80/90 wt in both my rear end and transmission, and UTF in the Hydraulics.
At the bottom of the clutch housing you can see the lines from the hydraulic reservoir that comes through the transmission to the hydraulic pump on the left side of the engine.

Whoop! I meant to say the hydraulic pump and lines are on the RIGHT side of my engine, (if on the seat looking forward).

No the 3000 goes around the side.

You apparently have a leaking seal between your hyd sump and tranny....the one around that drive shaft pictured therein. Don't worry about it, not worth tearing the housings in half and all that stuff. Just drain out the tranny as it fills and top off your hyd-diff sump. Been doing it for years on my 2000 as I said.

I'm good, just trying to help a little bit where I can with a picture or 2. I was changing the filters in that picture and thought someone would like to see what it looks like inside the sump. The OP is a little confused, he thinks you told him when his 3ph raises and lowers it fills his transmission. I said it has to be a seal, loose screw, gasket, Etc. because there aren't any hyd lines that go between the trans and rear diff.

Walk around to the right (curb) side and look right in front of the brake pedals. 2 tubes, 2 different sizes, in and out hyd lines to the pump. Follow the leader to the rear sump and the flow regulator knob.

re -edit
for those with a Ford 3000 with SOS transmission if anything other than Fords approved lube (Ambra) is used in the transmission they could (probably will) damage it.





that being said- my other tractor uses common universal tractor hydraulic oil for trans, hydraulics, rear and front axles. .


did a little checking in my fords manual:
for a 3000


oil capacity is about 24 and 1/2 quarts rear axle
and just under 14 quarts for the manual 8 speed transmission
so the Fords use quite a bit of oil- more than 9 gallons

from the ford manual
It is the same fluid (Ford M-2C53A)- the old # for both trans and rear axle.

so if the standard transmissioned 3000 has seals between trans/rear axle it must be to control fluid level in the transmission??

So :confused3:
