Hello Tom welcome back! The first time I read your
post I went through it a little to quickly. I thought you
were asking if we could tell you if you had the ability to
take it apart and fix it. Especially since you only had 2
posts prior to this, I was working up quite a reply to
that. But I see just the opposite is true. I will attach the
exploded view from the CNHI online parts book. I do
not know how much you lurked here during your 12
year absence but Dieseltech is a legitimate rebuilder of
injection pumps. Many on here have shipped pumps to
him for rebuilds, he lives in Indiana. Always hear how
economical his prices are and how satisfied they are
with his work. Send him an email if you want pursue his
assistance with this. BTW, from the link you can access
all the parts diagrams for your tractor. At the upper left
click the description of your tractor to the right of the
..Home.. icon to view all the parts sections. If you
happen to have an International Wheatland model type
806 in the search and select it instead of the Farmall
model.
