Mason,

Yes, it is new to me, only 25 years old. As far as I know, it is a Eagle factory setup with a 470 hp 12.7 Series 60. Instead of modifying the frame, they have lower valve covers on the first two cylinders (toward the front of the bus), and Jacobs brakes on the other four cylinders towards the rear of the bus. The radiator fan has the pulley system. The HT741 is identical to the HT740 except for the push-pad ATEC controls instead of the cable actuated hydraulic control. I'll get some pictures taken soon (my busy season has started for my business, so it might be a day or two). It turned out that it has a 90,000 BTU Webasto, and two generators. One is 17.5 Kw, and the other is 15 Kw. Got to have backup! There are four CruiseAir basement A/C's, and three roof airs, and a large Magnum Inverter. Lot's of stuff to play with. :?

Walter, If I understand right, what I circled in red is additional support under the 3x3 tubing? Also it would it looks like it would drag the ground before the oil pan?

Mason, yes, it sure does stick down a bit protecting everything from bottoming out. Someone sure thought a lot of extra strength was needed. It's welded to the regular frame that would support a 2-cycle. Picture 001 shows it full length from the outside. It runs from past the rear engine mount all the way to the rear of the bumper. Since there is a hitch mount attached to it, it might be for the dual purpose of frame reinforcement for the Series 60 and for a heavy trailer mount. There was a posting on the BCM forum in the last few months about a super heavy trailer frame mount on a Prevost that Cliff Allen spotted in a picture that someone had put on. At the rear-most end by the bumper it is 5" thick, so it is more like 6-7-8" thick towards the transmission. It must be adding a lot of weight. Here are some more pictures (the limit is eight).

Thanks Walter, the last set of pics cleared up my confusion.... Maybe!? I don't see how they would add a whole lot of strength, anyway in my application... The front of the 3x3 tube is very strong into the bulkhead behind the rear axle, and the rear of the 3x3 tube (in my case) will be supported almost entirely off the rear truss. (the one I rebuilt)

Good to have something bottom out before the engine, though. My engine has a nice 2x6 inch patch on the oil pan where presumably they (the school) scraped it on something that didn't want to move. There was a cross bar under the engine at the lowest point, It was bent almost beyond belief.

But back to progress in my shop... I successfully got the entire wiring harness out last Thursday night, that was a little interesting but it is done now! I also cut out more pieces in the back of the bus, when is this going to stop! :evil: (cutting and replacing)

As a side note, I took 500 pounds of steel to the scrap yard, got $40, 33 pounds of copper, $54! Wow! :o :shock:

Mason,

It may very well be that extra reinforcement is for the primary purpose of the trailer hitch, but since it is welded it sure must add some strength to the area, and protect the pan. $160 a ton for steel is decent nowadays. It used to be $240-260 a ton a few years ago. I have tons of various metals to scrap, but I am waiting for higher prices. :lol:

Walter: I guess I am just too impatient to wait for higher steel prices!

Any reason why the slightly bigger tires won't work on the eagle? They fit fine, and they are pretty new, the other tires are old.
But I can't seem to find the date code?

Tire size wise, it is just a question of appropriate rim width, and then clearances all around the tire when in use. The revs per mile need to be considered in the total gear ratio so that you can cruise at the most economical rpm's. Check both sides of the tire for the code, if there is none, that should be a red flag. It is required for tires sold in the US, I believe.

I had my old tires mounted on the bluebird but one had the date code on the outside, it was a 2008, so not super old but the new (to me) tires are 2016 on the drives, 2017 on the steers, and 2015 on the tags, which are almost bald so I will have to replace them sometime...

Walter, clearances are fine all around, its my lucky day! :D
