PDWA

[Charlie Brown <cb1500@erols.com>]

Jeeze folks,

All this talk about the PDWA. It may not be everything you ever wanted to 
know 'bout the device, but I did an article that's on the VTR web site. 
These things just aren't that complicated. Go to 
www.vtr.org/maintain/pdwa.html

There's a cross section drawing, a parts photo, and an overview of 
operation and repair (mostly for the later single piston model, but with 
information for the early 2 piston unit).
