Hi Dennis. I just did the brakes on my D17 this past weekend...so here's my 2 cents worth. From what I've gathered a WD must be the same setup. This pin, as you've been told is on the bottom, held in place by the clip, secured with a short 3/8ths bolt. It goes thru the lower housing and then thru the holes in the individual brake shoes. I started out by spraying everything good with WD40 (inside and out). What I did was to take a 1/2 nut and weld it to the outside of the pin....where you'd hit it if you were driving it in...I had a 6 inch piece of 1/2 all thread and about a 4inch piece of 1 inch pipe, a second 1/2 nut and a washer large enough to cover the end of the pipe...pipe fits over the nut I welded on and up against the housing....all thread screwed into the nut I welded on....pipe over this and then just start tightening the second nut, thereby pulling on the pin. I tried drilling---which would have been a better deal I thought, but the pin is hard as the hubs of heck, and my drill bits wouldn't do it (maybe these other guys have better bits). Anyway, here's the way mine went. I had everything ready, welded the nut on, let it cool a little, but not completely cool, and much to my suprise it began to come out just a little, maybe an 1/8th of an inch, then got really tight. I then took the puller off and sprayed everything good again and drove it back in (pounding lightly on the end of the all thread). Pulled again and it started out and then got tight and I pulled the nut I'd welded on...off...I I welded it on again. This time after I had it out about an 1/8th or so, I took a little pipe wrench and got it to begin the rotate...spraying the heck out of it with the WD40...once I got it to make a complete revolution, it came out so easy you couldn't believe it. If you go down the page to the D17 brake question, you'll see where so guy suggested welding a piece of flat iron to the pin....Looking back, I think his idea is really better than the way I did mine...if you took a piece of 1" by 3/16ths flat...grind a half hole in it fit it over the pins like the clip that holds it in place...and then weld it to the pin.
It would be much easier welding and you'd have the leverage of the flat iron to begin to roatate the pin. I think you could use a big screw driver to put some outward pull on it and I'll bet it would work pretty good.
