Here are a couple of pictures of the walking beam shaft, and the tensioner shaft. The walking beam shaft has a round tubing top gusset, and 2 angled side gussets bracing it to the chassis. Not sure if the tensioner runs all the way across, or is 2 stub shafts.

I got a surprize at work the other day, as the previous owner was in and dropped of a complete engine gasket set, and a hardbound copy of maintenance manual SNOW-B3. The book has an old label on it from "Shamrock Const. Ltd".
Today I stopped in at the yard where the "extra" engine was left in storage a few years ago. The owner has since passed away, but his son is going to let me go on a hunt for it. He doesn't remember it being brought in, but thinks that if it was, it might have been put inside of a van or bus out in the yard. They have been scrapping out a lot of the older stuff, but I am hoping it might still be out there.
