On looking on another post I found this on Duey's website:

TIP

If you tie up the rear lift arms, the cylinders stay full of oil. If you then fill up the hydraulic reservoir, be very careful if you lower the arms later. There is a vent for the hydraulic reservoir under the inspection plate under the starter (one of the little traps that AC engineering created.) (usually a brass elbow installed in a threaded hole) This vent will squirt any over filled oil directly onto the foot clutch!!! On my tractors, I have plugged this vent with a pipe plug. Then I drilled a hole and welded a pipe coupler in the inspection plate under the starter, at an angle, to miss the starter and installed a cylinder vent. The result is a dry clutch as oil fumes and any overfill are vented to the outside.

I have a WD with a Farmhand F19 loader on it. I am always afraid of over filling the hydraulics...Have any of you done what Duey is talking about and do you have photos to show??
Thanks

According to an original Allis WD 'Operating Instructions Manual'

you check the hydraulic oil level with the rams extended.

Quote " Keep filled to high mark on bayonet gauge with rams extended"

But if you have a loader installed, I think you leave those rams retracted / lowered.

the top mark on the dipstick itself says "full with rams extended" but that is for lift arms only loader rams I think are longer so should have less oil in reservoir for when they retract?

Full is full with the lift arms extended. it don't matter what else you hook up to the system. If you have a loader, you check the level with the lift arms extended and the loader down.
