  1. That's what I did when I swapped over my B-42 to diesel. I was able to get a B-61SX from behind the cab forward, it had everything but the motor. Everything bolted right in, front cross member, transmission mounts, etc. There's a lot that you'll need that you'll have to scrounge for to get it done right (Shutters, brackets, air lines). The good thing is, the frame is predrilled for both mounts(Gas and Diesel). It was actually a very easy swap to bolt right in. I started off with a 1957 END-673 for ten years and after having a major issue with it a 1973 ENDT-675 (237) since 2011. Miss the bark of the 673, but love the power of the 237.

    does your backdrop have the fin that seperates 3 cylinders in it? All that I have seen with the fin will say Cummins Diesel on the 2 pieces.

     

    Yes, there's a cast divider separating the cylinders. Three upfront and three to the rear. The gasses meet as they enter the exhaust pipe. I've been told that's where the exhaust note comes from.


  3. Well, my text disappeared when I posted those pics. But, it's been two months since I touched this, didn't think I would be that busy. Finally got on it this weekend, finished all the welding and primed the frame. Got the donor frame to the sandblaster and into the shop for primer.

    The big score was finding a "Back-Drop" exhaust for the Cummins. It's super nice and once its painted and installed I'll post some pictures.

    Nothing like getting things cleaned up and new paint on them! I notice your floor looks old...when you built your new shop, did you reuse the old foundation and floor?

    It's the original floor with 3/4" plywood layed over it as a work surface. I put it down when I did the other B. I'll probably replace it at some point.

    I didn't use the mack rear I used the Rockwell from the freightliner air ride cutoff.   It gave me a much better gear ratio.  My last mack crossmember is at the rear of the doubled frames.  It is about 2' of just freightliner frame  before the first freightliner crossmember.  

    I've got a 4.62 rear and a double overdrive Triplex going in this one. Nearly the same as I set up in my other B, but with 24.5" rubber going on this one. Cruises nice at 65, with more top end. The Triplex gives good flexibility around town and highway.
