I need to add some hydraulic oil to my WD, and I see that the manual says "for above 45 F, use SAE 20, and for below 45, use SAE 10"... Well, does anybody have any idea what I can use? I know a neighbor said he uses the same 10w30 he uses in the engine for his hydraulics. Didn't know if I actually should get SAE 10 (can be hard to find here, I think) or if I should find some sort of universal hydraulic fluid (or if mixing that with whatever is already in there would be bad).

Also, apparently there are two different fill plugs for the tranny/diff (but 3 drain plugs)? Do you just fill the tractor until it is full to the top of the plugs, or is there some sort of fill mark without draining and refilling the whole thing? Was going to use some 80-ish weight oil in that. The manual says "fill to level plugs", but I only see it call out the 2 fill plugs in the lubrication manual. Where are the "level" plugs for this system?

Also, anything else I need to grease with regular grease, like the clutch? Also, I think the PTO is lubricated from the tranny/diff reservoirs, but are there some grease zerk fittings on it I should hit up as well?

Use hydraulic oil in the torque tube which is the
hydraulic reservoir. There should be a dipstick
on the fill cap for that one. Originally they
recommended engine oil because the oils of the day
didn't have detergent and thusly less issues with
foaming. Any of the quality hydraulic oils out
there will work just fine (303, HyTran, HyGard,
etc)

As to the transmission and final drives I would
use 80w90 gear lube. The fill levels escape me
but usually you fill to the bottom of the fill
hole on the side of the trans. I think one is for
the hand clutch and the other is for the trans and
diff.

I have always used 140 in the Diff...
You push the foot clutch lever forward and lock it forward with the lever provided that pivots..
Fill to top of threads (Full)..

Trans: Pipe plug inside of frame-rail UNDER the Hydraulic filler..(at bottom inside of frame rail).

I still use clean engine oil in ALL my tractors, as we here have always done..but, my newest is a 1959...
Use what will be compatible with all that may be used with this tractor and others..

Ron..

Well, both fill holes were plum full to the necessary level, which was good. Hydraulic took about a quart and a half to hit the proper mark with rams extended. I got my hands on some non-detergent SAE 10, which for the weather here lately, should work fine. Yeah, those two filler plugs were not in a fun to get to spot. Everything seems oiled and greased well now!

The whole hydraulic system only takes 2-3 quarts. I would drain all the oil out and replace with new hydraulic oil of the brand of your choice. It is probably fine, but I would want to mix oils if you have no idea what or how old the original oil is.
It wouldn't be a bad idea to replace the rearend and final drive oil if it's been many years. These are the first thing I do when I get a new tractor.
