Squid, I have a single axle dump truck with a Thermodyne that weighs 14,200#. These trucks are made heavy duty, and they are heavy, even if they are a "light" model with lots of aluminum. I would say you are safe assuming 12,000 to 14,000 pounds for a tandem tractor. Scott

Justin, I was researching starters/alternators & thought of your post. Here's a couple of websites that may be of general help and good reference: http://www.prestolite.com/pgs_training/training_0.php - Prestolite (Leece Neville) electrical manual http://www.hss.energy.gov/NuclearSafety/te...d/standard.html - There are a bunch of manuals here. Some of the electrical fundamental handbooks deal with DC circuits, but mainly AC circuits. Hope this helps, Scott

Glenn, Those pictures are of the B615 I saw on eBay. It looks like the air cleaner has been removed; I can see a little bit of the cowl fitting... My B613 has the tin cover over the radiator. Fifth wheel, that's a good catch, I had never paid attention to cab height. I guess with the dropped floor on the B70 series cabs, you would need to raise it up. So the fender extensions do provide a vertical adjustment for the rear bolt pattern of the fenders. Now I gotta go look! Scott

Hi Glenn, My B613 has the standard radiator, not the wide one like my B70's. Now that you mention it, it seems HarryB has a B615 and the photos he sent shows the wide radiator. Harry indicates that most of the B615's were sent to Australia, but I did see one on eBay that the guy thought it had a detroit in it (it may have been a V8 Mack). I'll attach a couple of photos of the eBay truck, but they aren't the greatest for size/resolution.

Cayoterun, The B73, B75 & B77 series trucks have a longer hood and include fender extensions to allow installation of a cummins inline 6 engine, which is several inches longer than a 673. The hood will be too long and have a cut out for the air intake. The B61 air intake enters the front portion of the cab before entering the engine compartment. The air intake for the engine on a B7x series enters directly into the engine comparment. All that being said, if you have a complete B61 (with damaged fenders, radiator, etc), the radiator, headlight panels and fenders from a B7x series should bolt directly onto your B61. I haven't measured the bolt spacing at the bottom of a B61 radiator vs. a B7x series, but they look pretty close. As mentioned previously, you would need the B61 hood. I haven't verified the fender bolt pattern either, but would be very surprised if there was a difference. I'm assuming you have everything for the B61 and have access to a B75 front clip. The B75 cab mounts to the frame a little farther back, the rear spring hangers for the front axle are different (on a B61 the front cab mounts are part of the hanger, where on a a B75 they are separate; at least on mine), and the access panels between the fender and hood are different (probably need to use the B61's). Let me or HarryB if you have questions - I've got a B613, and several B7x series trucks; Harry B is modifying a B6x series to fit a large bore inline 6. We've been working the issue from a different angle, but could probably help you out if you decide to jump in! Scott

Paul, I was able to find a couple of wheel studs for my '58 B613 at NAPA. They were a special order, but just measure one up with a caliper so you have accurate numbers for length, etc. Then take one in when you go. They should have a set of books available to look at & compare with your sample. I will see if I still have the receipt for mine when I get back in the shop tomorrow & get you the part numbers. Scott
