Houlio,
When you and your dad did the rebuild, did you use the two different size chains on the back suspension like it shows in diagramm in your old manual? (Five link/seven link, five link/seven link series) I notice that the chains that Dan Shaver makes up are three link, but they equal the old five link chains due to the larger chain size he uses. I found one old seven link chain (still had the original bombardier tag on it) as well as two of the old flat bar style links in our old shed and they are the same size; bolt eye to bolt eye. I believe that the two different sizes were found only on the older machines. (I may be wrong).
The reason I'm asking, is that the old 47-48 narrow gauge I purchased sits very low on the back end and upon inspection, I found that it has some three link, some five link, some six link and one old seven link chan on it.
I will be redoing the suspension next fall and was curious as to what you guys did. Also, I think your machine has four chain links on the front; not like the five shown in the manual. Did you use a larger size chain there, or is there allot of forgivness on the link length of the chains used?
Thanks Houlio.
