John, the only experience I have is with the #3 Hydra-Lectric unit. The first article will deal with getting the unit off the tractor, taking it apart with tips on the restrictors in the lines, adding a "power beyond" unit, and the simple jig I made to hold the unit so a person doesn't need to put it on a bench and roll it around to work on it if the pump is not removed. It will be some fairly basic stuff. 
 I had a chance at the winter get together to buy a piece of literature (8-10 page brochure) on the Hydra-lectric units, but at about $5.00 a page I didn't.
 The next article will be on rebuilding the pump itself. 
 IF I could find enough tractors with different style units for pictures, I think an article of the differences and identification would be nice. I suppose this should be the first, but finding the different systems is difficult. 
 The weather is nearly perfect here and the family is gearing up for another busy summer. My oldest daughter will recieve her Masters Degree (7&amp;1/2 years) next month. We will help her move to Bloomington, IL (only an hour and a half away) for the months of June and July, then move her to Memphis, TN for a 9 month internship. 
 We are planning to be in Wisconsin in August for the National HPOCA Show. Do you think you will be able to make it to Wisconsin?
