wd transmission shaft removal: help needed

I pulled the motor on my wd to replace the clutch. The previous owner replaced the clutch with a remanufactured one I believe they used too big of a spline on the clutch. Now the trans shaft splines and clutch splines are worn terribly. How big of a job is it to remove that trans shaft. Any pointers on how to go about it?
 
AC service manual simply states remove shaft and pinion. I think it just slides out. Don't recall anything holding it in.

I can't answer your question since I haven't been into the tranny of a WD since I ws in H.S. in '58 or '59 and I can't remember back that far.
I will say that this is not a typical input shaft.
Instead, it is a long shaft running from the engine clutch back to the transmission (hand) clutch.
The shaft is retained by the two bolts holding the bearing retainer which also holds the clutch release (throwout) bearing. At the least, it would seem that the hydraulic pump would have to be removed as it's cam followers are driven off the cams on this shaft. Pulling the cover off the hand clutch will give you a better look at that end of the shaft. This cutaway view gives you a rough idea of how the shaft fits in with the other pieces.

I think Brian might be right. I've pulled a couple WC's apart and one WD, but I honestly can't remember how it comes out. Have you looked at a parts book? You can go to www.agcopartsbooks.com and check it out. Log on as a guest then search for WD.

I have a printed copy of the parts book. I'm going to try pulling
the shaft this weekend. Long days at work and drywall work in
my house are keeping me from working on getting the tractor
fixed and getting the garden in. I appreciate the help and
suggestions from everyone. Thanks.
