Filling hydraulics

This is my first tractor, Ford 640. Manuals that I have show the fill plug on left side, mine doesn't. Looking for info. Thx

The FoMoCo logo on the lift chest would indicate a newer assembly then was used on 100 series . Casting numbers don't fit and the auxiliary hydraulic plate don't look right either. Guys acquainted with maybe 1000 series tractor might have an answer.
 
Hi RTH If what Wayne said is correct try that plug on top of the diff housing. In the pic it is in the top left side, as you have the seat removed it would be on the back right as you stand over the drawbar. Looks a little like the back of the 3000 I used to have. Hope that might help.

Hi RTH

The differential and hydraulics are one and the same if it has a Ford 3000/2000 back end on it. You may do better to post this on the Ford forum as people who know more than I can assist you. This oil also goes to the gearbox and the level plug will be either a 9/16 or 1/2 inch plug an about where right calf/heel would be on the footplate as you sit on the tractor.

Regards

Matt did bring up an interesting question though. If the entire rear end is from a later tractor that sump would be a common sump.

Park the unit with the left side high (unless the oil level is fairly low), remove the round inspection cover with the PTO lever on it and with flashlight or flashlight and mirror look toward the rear of the cavity.

If you can see your ring and pinion, the sump is common and can be filled through the back cap plug.

If you can not see the ring and pinion because of a cast wall, you'll have to fill your hydraulics through that inspection cover with the tractor on a slope and the left side high.
 
Unfortunately i drained hydraulic fluid already, thinking I had the fill plug on the top left. I guess a newbie
mistake
 
Since you have a 600 tractor with a 2000 lift chest, (purely speculation on my part) you will need to remove the PTO shifter housing to fill the reservoir.

Well, since your oil is drained, you wont lose any by removing the inspection cover on the left side where the tractor sits.
 
"Cover" my bad. The plate held on by six bolts with the PTO shifter in it on the left side of the tractor. Sorry
 
(quoted from post at 22:00:33 03/17/19) Pic I found. But not a very big hole to pour 9 1/2 quarts thru

Someone check me if I'm wrong. However, I believe this plug is an auxiliary pressure port and not a place one can add oil.
 
Why not fill it through the dipstick tube next to the PTO handle? It will be a little slow, but you know for sure that hole goes to the hydraulics sump. Or you could pull the round cover with the PTO handle and dipstick in it and fill it to the bottom of the round hole then put the cover back on and top it off through the dipstick tube. I think it's only supposed to be a little above the bottom of that hole anyway.
 

I just had a similar question for my tractor ('64 4000). Anyway, I did not find either the I&T manual or the users manual to make it 'blatantly" obvious as to the location of the hydraulic fluid filler port. So, what i did was pull the dip stick and train a light through the opening, then I started opening ports until I could see the light shining through from the the dip stick hole.

This actually worked nicely for me.

It also helped that mine was 'bone dry' from having just discovered that my tractors inlet manifold was as useful as a screen door on a submarine.

Maybe the 'flashlight trick' can help you too.
