I'm in the process of changing the fluids in my wd45. No manual as of yet. I pulled the plug out of the pto and drained it. I pulled the plug out of the bottom of the hydraulics (just forward of the pto) Is there only one plug for the differental, just off the centre???? Is that my tranny and hydraulics drained at this point?? Will be draining final drives. When refilling, tranny sae80 17 quarts, where is it added? hydraulics cold weather 6 quarts sae10, added through the dipstick hole???? Will the tranny fill the diff. or do I havee to add this somewhere else?? How do I tell if I have enough in each area. Sorry about all the questions I guess if the manual was here I wouldn't have to ask but I want to get on with this.
Thanks again

The drain plug in the bottom of the hydraulic reservoir is/should be a magnetic plug that should be cleaned before reinstalling. There is a drain plug on the bottom of the transmission case. There is a ddrain plug in the bottom of the PTO case. There is a drain plug in the bottom of the rear end case. There is a drain plug in the bottom of the control valve on the aft end of the hydraulic pump. You have to remove the pans on the bottom of the final drives to drain those. The hydraulics get refilled through the dip stick hole with any good brand of universal hydraulic/wet brakes system fluid, better choice than engine oil in my opinion. There are two square head pipe plugs on the same side of the tractor as the hydraulics reservoir dip stick. The first one back from the hydraulics is the transmission, fill to overflow with 85W140 gear lube. The next one back is the rear end, fill to overflow with 85W140 gear lube. The final drives are filled to overflow with 85W140 gear lube through each pipe plug on the inside face and a few inches above the pan gasket surface of the final drives. I use 5W30 oil in my engine during the winter and 30W in the summer.

I have a picture blown up and framed in my "tractor room" of a Farmall M. It was my Grandpa's tractor, of which whom I never got to meet. He froze to death getting this tractor out of the barn to pull a truck out of the ditch before I was born. Anyway my dad and aunt had to sell it at the auction, ... [Read Article]
