Archaeology Lonnie, we're involved in a mini dig here. You never know what you may
turn up when you start to dig into one of these old Stovebolts.
Castle/slotted, same-o/same-o
http://en.wikipedia.org/wiki/Castellated_nut As I was saying, there are lots of contradictions between the Service manual, the Parts
manuals, the Factory Assembly manual and what was done on the production line. Yes
the technical writer wrote in the service manual "self-locking nuts" but if you look closely
at those outer bolts in Fig.20 on page 6-13 of the 1948-51 service manual you can clearly
see holes drilled in them for cotter pins. And the parts manual also calls out slotted, ie.
castle nuts for that application. My 53.000 mile 1950 had the original front motor mount
and it had pinned castle nuts.
And you my friend are forcing me to dig a little deeper. I just went out to check my
48,000 mile 1954 which is up on blocks in the barn, (0° out there today) and it has self
locking nuts, no castle or cotter pins. So somewhere down the line they did make a shift to
the self-locking nut for adjustment and so you are correct on your ’54.
But, the fact remains that we will probably never know for sure just like many other
things about how these trucks were assembled and when some of these changes took
place.
