Questions: Two drain plugs for draining trans and differential on WD? One must be on bottom of PTO? Also, what is capacity after I drain? Thanks.

I use Allis 821XL, or equivalent, everywhere on WD's through 190's. dealer recommended that, and saves any confusion. Only need one barrel of oil then.

Per the WD service manual. Transmission, Differential and Transmission clutch SAE 80EP all year round. Drain and fill as previously said here. Hydraulic pump seperate, dip stick on left side, fill with sae 20W NON_DETERGENT! This also lubes the pully. Non detergent VERY Important!

Dave, which plug is drain for area that should contain the nondetergent oil? I put the 80 weight in all areas including the dip-stick one on left side where you said the lighter weight non-detg goes. Got the additional messages too late. I drained a plug right in front of PTO. One on bottom of PTO and a larger one back on belly above snap coupler bell.

Dan, There are 3 drain plugs for the gear oil. One under Differential, one in plate under tranny, and one on bottom of PTO housing. Fill all three compartments thru the transmission filler plugs. The filler for the Hydraulics is the one with the "bayonette" dipstick. The magnetized plug in front of the PTO housing is the main drain for the hydraulics. The magnetized plug is to pick up metal that may get into the system; probably mainly from the belt pulley gears which are lubed with the hyd. oil. To drain the hydraulic system completely, you must also remove the small plug on the bottom of the hydraulic control unit. The hydraulic system is supposed to hold 6 qts. I use a modern "Hytran" fluid myself. The fluid level should read on the high mark with rams extended. Contrary to what it says in the operator's manual (and the parts manual), the plate under the tranny is not a P.T.O. cover; unless there is another P.T.O. option for industrial tractors that I'm not aware of. Hopefully, you didn't operate the tractor and circulate that 80 wt. gear oil thru the hydraulic system!? Brian G.

Yes the plug on the bottom of the PTO housing is one of the drain plugs, although I don't think it actually tells you this in the operator's manual.

Trans, Differential and Tran. Clutch. 17qts, l extra w/pto. Drain Plugs- Bottom of trans., bottom of diff., and bottom of clutch Housing. Use 80EP the year around, per manual. Fill all three compartments through trans. filler plugs. Hope this helps.

I would get a second opinion on that. It's been a few years since we had WD/WD45's. My recollection is that the transmission clutch (hand clutch) is in a separate compartment from the transmission. It uses SAE 20 motor oil and also has the hydraulics and the PTO gearbox in it. It has a short dip stick on the right side just inside the frame rail. That is also where you fill that compartment. The transmission is the next compartment back. I believe it has a filler plug. I'm not sure of the oil type for the transmission. I would question 80 EP. Back in those days they were using non EP gear lubes in transmissions. Get an Allis Chalmers WD manual and be sure.
