WD PTO 6 spline shaft diameter

I'm about to order an PTO overrun coupling for my WD but I failed to measure the diameter (I'm thinking it's 1 3/8ths? 1 1/8th?). Unfortunately it's about 900 miles away so I can't just pop out and measure it so I was hoping one of you could help me out with the shaft diameter (6 spline). I can find the part online but it never mentions the diameter.

Also, this WD is new to me: the hydraulic only seems to work when the foot clutch is released -- kind of a surprise to me -- is that standard (I'm not quite seeing it as a feature)

Thanks all.
 
The WD PTO spline is 1-3/8". Yes, the foot clutch must be engaged for the hydraulic to work. To stop travel but continue with PTO and/or hydraulic, throw out the hand clutch.
 
It is a feature. Gives you live power to belt pully and PTO. However don't expect to shift or engage a gear from stop using the hand clutch with cold oil. The hand clutch
runs in oil and will drag until the oil is warm. An oil thinner than 90 weight will help this situation.
 
Its not a feature, but the way they made them. Allis was WAYYYY late with independent PTO. The WD PTO and hyd only work with the transmission clutch engaged.
