Another diesel 40 build (1 Viewer)

Obviously the trans will be changed out if the B variant is used but dimensionally it will be the same as the 2f/12ht variant so it will stay in place for my purposes. The B input shaft is longer and the B diesel has a longer bellhousing so for mock up this is ideal. If I had used the B trans I couldn't mock up the 12ht.

Been busy blasting parts and welding up some holes on this 40 over the last week or so. The hood had three holes in the center front for perhaps a aftermarket ornament at some point. Someone had also installed 70 series turn signals at some point and moved the hood latch hooks up on the hood. I welded these up with decent success.

I took a load of parts to the blaster yesterday and picked them back up today.

The galvanizing place I'm using this time has a $250 minimum charge and with the 40 frame alone falling under that, it made sense to do my other m416 trailer during the same go. I tore it apart last week.

wish i had done that. i just blasted mine and had it painted but there are areas behind some seam sealer that weren’t covered and are dusting through already. oh well. i’ll keep it at bay for now and then have it restripped and then dipped.

With the frame back from blasting, I wanted to add a couple of welds to some common failure points.

 

[roma042987]

I welded the spring perches, and blasted the bib myself since it fit in my cabinet, I was expecting it and the hood to be full of bondo since this was a Costa Rican rig but they both came out nice.

The hood did however have a couple of cracks on both sides. To keep them from spreading and to repair them, I drilled a couple of holes on either side of the crack and welded in a splint. I then welded the crack and ground it back smooth.

Any warping?

 

[White Stripe]

You galvanized the hood? Did they turn down the temperature for the hood and Bobcats or something?

Any warping?

Hood warped, bib did not. I understood it was likely but wanted to give it a shot.

yeah I did the hood. Bobcats?

How much weight does the galvanizing process add and how badly did the hood warp? If it was braced do you think it would warp?

I'd say the additional weight is negligible. It generally depends on surface area. The hood I'd guess is 3 to 6 lbs heavier. It's warped, I mean you could skim it with bondo I suppose and smooth it back out. I'm not sure on additional bracing. I guess it really depends how much you added.
