Nice!

Thanks! I may try the speedo and see how that goes......

I like those gauges too. Did you get them as a set, or individually? If it was a set, I'd be interested to know which set and which wiring harness.... The gauges in by B85F are not original, and what they put in were just boring Stewart Warners. These would be a nice improvement if I can match them all up, and they aren't too difficult for a non-electrical person to figure out how to wire up.

Thanks Paul. The mechanic Dennis uses and sent out is top notch, and is very familiar with the 707. He went through the carb, and everything in there is good, except for that slight groove on the needle. We sanded it, and it seems to be OK, but he's sending me a new one, just in case. But the fact that it runs great over about 1200-1400rpms is indicating that the thing is just flat out getting too much fuel blow-by at any rpms below that, so we're pretty sure the regulator will solve it. Of course, no one locally has a regulator at that low a rating, so I have to order it and likely wait 2-3 days.....

Thanks - already made that call and have one on order. It's actually not all that easy to find either a pump OR a regulator that goes down to 3psi, but Holley has one, and I have it on order. So, we'll know in a few days if that solves the problem, but I'm pretty optimistic. I'll also get a new needle in case we didn't quite get rid of the groove and gas might still be sneaking by that as well.

Ahhh..... That's better...... Dennis at OldMacks.com stepped up to the plate and sent his mechanic out to see what was going on. it was obvious that it was burning very rich, so after changing the plugs, cleaning up the carb, sanding a groove off the needle, and installing in in-line fuel filter it ran better, but still was flooding at low rpms. We discovered that the fuel pump was rated for 5-9psi, but the Zenith carb is rated for 3psi. So I'll get a new pump, and a new needle, and hopefully all will be well. But as you can hear in the video, as long as the idle/rpms stay above 1100-ish, it runs great. Very encouraging...... 2016-05-12 16.10.03.mov

I think it looks great!

Nice! It's got a great stance.....

Here's a picture of it that they have on their web site.....

Andy - nice that you were able to not only find it, but to buy it! Good luck getting it home.....

Up in this neck of the woods, Palmer Spring in Providence has access to lots of springs, and they have a blacksmith shop on site to make anything custom.... I've always heard good things about them. http://www.palmer-spring.com/services.htm

Ooohh - that's a beauty!

That's looking great!

My great uncle built and owned the local cement plant in my area (Wescon) for a long time, and he (and others in the surrounding areas) seemed to favor Autocar rear dumpers when I was growing up. When the building boom hit southern New England in the 80s and they were all flush with cash, it seemed that everyone in a 30 mile radius of here updated their fleets and they all went to the front dumpers. The only rear dumpers I see now are occasionally up in the Providence area, and they seem to be mostly run by the big construction outfits doing road work, like Cardi Construction, and I think that Pawtucket Ready Mix still ran a few into the 2000s, although I haven't seen any of their rigs in quite a while, and I'm not even sure they're still around. My great uncle also had a couple of old Mack dumps that he ran back in the 40s and 50s. He retired them in the 70s when the union demanded power steering, and I lived close enough to the plant that I used to ride my bike there, and go out to the back field and play in the old dumps. I think that there were a couple old LJs and an old Autocar out back there.....

Looks great - you've brought it a long way!

Thanks! Now I just have to figure out what happened to it during the trip here. I'm told it ran beautifully when it left, but since I got it, it's been running like crap. Been checking all the ignition/battery wires, and that all looks good. Now i'll have to check the fuel filter to see if it's being starved. I think it ran out of gas by the time I got it unloaded and down to my neighbors barn, so I'm hoping that the problem is just some crud in the fuel filter.... We'll see..... But otherwise, it's a great truck, and I'm happy with the overall physical condition of it.

Thanks Bulldogboy - I found the C-town pics and downloaded them. A couple of them actually helped confirm whether or not a couple things were original to the truck or added later....

So here are a couple shots of the B85 arriving today. It'll need a good cleanup, and there are few small things to fix. Also have to lower a mini light tower that's on it to get it into my garage. I'll post a few more pics once I get it home (it's in my neighbor's barn at the moment, as his fire truck is in my garage while he stored the B42 for the winter, as that was too tall for my garage!) and get it washed and waxed. Overall, I'm very impressed. A few rust spots on the body and back fenders that will need some attention, but overall, it's a very nice truck for its age.

Hmmm.... I think I vaguely recall seeing a pic of those Bermuda Bs somewhere along the line. Don't remember a mention of them being diesel though. Maybe in one of the B model books I have. I'll have to poke around and see if I can find that again.

I checked their website, but didn't see anything related to this. I'll have to look again and search harder this time. Will be interesting to see.... The Bs have also always been my favorite. I'm most partial to the B81s, but they're huge, and I can't fit one of those in my garage! And since I've always loved fire trucks (used to drive in my local dept.), it only made sense that the end game for me would be a B model fire truck.....

It's the 707 gas. But it does have air brakes, and even a Maxi-brake. I don't like old hydraulic brakes, so I'm happy about that. I'm not sure I've ever seen a B85 with a Diesel. Anyone know if any came from the factory with the Diesel? I believe that this is from Chestertown NY. But RI is going to be its new home....

Ed, Mine's 1216, so they weren't quite neighbors on the assy line.....

I like that pug-nose look

Yeah, that was my first thought too. Would it have originally been built as a dump, or is there a reason that someone would want to have a tractor with a frame that long? Either way, it IS a nice looking R....

Well, my deposit check's in the mail, and if all goes according to plan, this rig will be headed here in the next couple weeks.... So glad to have another B85! It means that my B42 will be hitting the road, and I'll miss it (although I never did get as good on the Quadruplex as I would have liked!), but I've wanted another B85 for a while, and probably should have just been a little more patient in waiting for the right one to come along....
