I recently purchased a wd, on the left side of the tractor, down close to the frame rail, there is an oil cap with a short dip-stick on it. On the dip stick it does not tell what type of oil to put in. The tractor has sat in a barn for many years and there is no oil on the stick to compare it to. Can anyone tell me what to put in to bring the level up to full?

Do your trctor a favor and change the hydraulic oil, (the dipstick you found), the transmission and rear end oil, (3 drain plugs under the tractor, one is the PTO if you have one, one is under the rear end area, and one is in the sheet metal plate under the transmission. There is two fill plugs on the left side of the tractor, look and you will see them. And don't for get the final drives. Take the pans off each side and clean them out.You can fill them almost full, put them on, or fill them with the filler/level plug on the side of the pan. Many don't ever change the final drives and they can be pretty bad. With the wheels off or in a wide position they are easy to get to.

i agree with Tom, drain and refill. I like the new trans-hydraulic fluid for the transmission-pto case and 90 wt gear lube in the final drive boxes.you can get both at farm center, or WalMart.

Yup, that's the hydraulic oil fill. I forget what the manual calls for but since I replaced my pump with a rebuilt and added new hoses, ect. I've used a modern hydraulic fluid (32 weight I think) with no problems.

A word of caution: these old WD style tractors can leak badly from the front hydraulic reservoir seal which lets oil into the engine clutch area. If you're going to fill your hydraulics full, open the clutch inspection plate and place a bucket under it. I've even added extra washers between the clutch cover and clutch housing to allow the oil to drain until I get around to rebuilding the engine (which will let me to get to that *^%@#$ seal). I've christened the bucket "Valdez III" for the number of times I've forgotten to remove it before driving the tractor off (yes, it leaks that much).

If you get the tractor OPERATOR manual, it will show all filler plugs and also the proper oil for each cavity. I suspect you're looking at the hydraulic oil filler, and the proper oil depends on the operating temperature range- probably a 20 weight, but the manual will give correct info.

Check out my website (link below). Among the links there is one that shows the poper oils for the various tractors (from manuals I have, including a WD). There is also a link that shows some images of fill points.
