Question about rear drain plugs

Does anybody know why there are two drain plugs for the rear and only one for engine oil. Don't both rear plugs access the same reservoirs. Also I'm using # 48 hydraulic fluid which I was told was cool for the PTO and tranny........
 
What tractor always good to let us know that. If an N series there are 3 drain plugs but only one fill plug. 3 drain plugs due to the ups and downs in the rear end hyds and trans so you have to remove all 3 to drain all the oil

There are two drain plugs because the bottom of the cases is lower than the path between the two. In other words so you can drain both cases all the way to the bottom.

The fact you say "#48" oil makes me think you are using a true "hydraulic" oil designed for hydraulic systems only. If so that oil is not intended for use in final drives and/or traansmssions and lacks the wear preventive additives needed for gear boxes. A "universal tractor transmission" type fluid is used in common sump tractors and is specially formulated for use as both a gear/final drive lubricant AND a hydraulic fluid. What precisely does the label on your "#48" fluid say it is?

Ron.......iff'n ya drive yer N-Tractor front wheels up on 4X4 blocks, then you will have enuff slant to drain ALL 5-gal of 90wt gear oil out the square diffy drain plug where it will peeeeee with some degree of accuracy innna shallow drain pan. That 3-in drain plug of the tranny and corner hydro don't do it.

Don't know what #48 hydraulic fluid is. Correct hydro fluid will say meets Ford spec: M2C-134D summ wharr on the lable. .......oily Dell

Actually I suspect he meant #46 which is one of the ISO viscosity grades used for hydraulic oils. Common anti-wear (AW) and rust and oxidation inhibiting (RO) hydraulic oils are not suitable for use in the drive line of a common sump tractor. They are for use in machinery with a dedicated hydraulic sump - e.g. an NAA or similar tractor.....

I've always pulled the PTO shaft then used a come-a-long to pick the tractor up by the front bumper. Seems to work. Have I been doing it wrong all this time?
 
The reason there is 3 drains for the drive train
is simply that each has a low sump and in order to
completely drain any one of them that plug has to
come out.

Dan, I Replaced my TSC Travlers Ford Tractor Oil with the NAPA SYNGARD J20D which is equivalent to the John Deere Low viscosity J20D oil.

External hydraulics work 100% better. The front mount pump doesn't make all that noise due to cavitation caused by the thick Ford oil. Control valve and rear hyd cylinder react immediately now.

Does NAPA make a product that you can recommend so I can exchange my AW-46 Hydraulic Oil that I bought because it says on the side for Farm Equipment as well as other machinery.

NAPA sells several different brands of "[u:fa609d646b]universal tractor transmission fluid[/u:fa609d646b]". Any of them should be fine. Expect to pay $50 and up for a 5 gallon pail.

And JFYI the viscosity of a premium UTF is roughly equivalent to an ISO 68 hydraulic oil. The J20D fluid that greywolf likes to use in his tractor with the external pump is a special cold weather formulation and has a bit lower viscosity than the Ford M2C-134D specification that Dell cited. It is roughly equivalent to an ISO 32 hydraulic oil. My recommendation is unless you need a really good cold weather oil (external pump or really arctic weather) stick to a conventional UTF (e.g. M2C-134D type) in your 9N.
