Hey Dave... I sure hope your brakes aren't on backwards!!! (I double checked with 155W since that had S cam brakes...)
So here is a 'Holiday' Update for everyone!
This past week we decided to work on fabricating a radiator shroud. Since I planned on taking the radiator off to help install the steering box, I figured this would be a good time to work on the shroud and the lower water neck.
The first thing we needed to do was find the center of the radiator. My guess is that the shutters/shroud that came with the truck was from another truck, probably with a Cummins. It's very similar to the one in our 761. So I couldn't use the original one for a pattern. So I cut a piece of cardboard to fit behind the radiator...

So to help find the exact center, I found a short piece of 5/16 gas line and slipped it over the grease fitting in the middle of the fan. Then I marked the center on my cardboard pattern...

After I was happy with the pattern, we removed the radiator...

Since I was off yesterday for Good Friday, the first thing we did was sling the Sheppard steering box... I covered it a bunch of towels so we wouldn't scratch anything installing it...

After it was close, my Dad guided it in place...

I used some long threaded rod to help guide it into place. Actually the threaded rods came from the brake chamber. When it was close, I screwed the rods into place and then pushed the box into place. All of the bolts went in fairly easy except for one. But after some time we had it bolted in place...

While I was working on the fittings for the steering box, my Dad polished up some 5/16x18 button heads I bought for the Stemco hub caps...

Then he finished installing both caps...

Then we started working on building the shroud. Last week I picked up a piece of 18 gauge sheet metal. So I sheered a piece 30 1/2" x 29 1/2" and bent 3" lips on both sides...

Then we bent filler pieces for the top and bottom...

Then we moved onto the pieces that would for the 'round' part that would surround the fan. The diameter of the opening needed to be 29", so the circumference of a circle is Pi x diameter so we needed almost 92" long. Since my brake is only 4' long, I cut two pieces 46" long by 4 1/2" wide. Then we folded over a 1/2" lip along with a 3/4" flange.

To help 'roll' the pieces, I used the 3" cutoff wheel and cut slots 1" apart the entire length of the pieces...

That wrapped up Friday... More to follow...
