NIce! I like the Hahns. Looked at a couple, but they're just too tall to fit in my garage.....

Interesting concept.... It looks like they sit lower than the stock seats. Still high enough to have a good line of visibility?

Superdog - just noticed that your little blurb thing says you have 165 Macks. Really?!? That's amazing! Do you have a photo album of them posted somewhere? Would love to see the variety that you have. I've seen a couple other good size collections on the East Coast (Yaworski Bros, Kemps in NH), but having that many must be truck heaven!

Nice - hate to see any fire trucks go to scrap - especially the Macks!

Ahh.... yeah, I saw the RI plates and wondered it had been nearby

Likewise - thanks for that final piece of the puzzle! Too bad he didn't survive - and only 20.... :-(

Yeah, he was clearly loaded, so between the tree in the front, and a load in the back, that can't have been a good outcome, unless as someone suggested, he jumped before impact.....

Did you find that one in RI? Any idea of its history?

I did a little bit of research to see if I could figure out when this happened, and who was involved. Info is pretty scarce from that far back, but it looks like the dump truck was owned by W. L. Dunn Construction in Cochranton PA. Dunn is clearly readable on the driver's door, and it sure looks like Cochranton if you put the letters on both doors together. They went out of business in 2010, and judging by what was auctioned off, they had about 20 dual axle dumps, and a few trailers. They were in business for about 90 years.... Vernon Motor Sales, who apparently owned the wrecker, is still listed as being an active corporation in PA, but I can't find anything on the web that would indicate that they are actually still in business. And I can't find anything about the accident, except for a very blurry page from the Titusville Herald in 1960 which a search led me to, but which I can't open without subscribing to the archive service. But given the age of the Mack, that year wouldn't be out of line.... I also believe that Josh is correct about the location, and it looks like the accident, was, in fact, at the intersection of 27 and 77. If this link works, you can see that at the bottom of Hickory, the 20mph speed limit is ending for trucks at the bottom of the hill, and if you cross over Rt 27, the road opposite is still brick, and you can see that where the wrecker is sitting, it is on a brick road. And if you change the view on google map so that you're in the intersection and look back up Hickory, you can see the arched window on the second floor of the yellow house on the corner, which is in the view of the picture of the crashed truck to the rear left of the truck. Looks like the tree is no longer there... I'm thinking it would be right about where the fire hydrant is now based on the roof of the porch of that house, which is what I believe is in the picture to the immediate left of the Dunn truck. Would be very interesting if someone could actually find an old newspaper article about the crash! Here's the current link to the Google map - hope it works: https://www.google.com/maps/@41.6399225,-80.1372793,3a,75y,210.58h,93.16t/data=!3m6!1e1!3m4!1shdyBBZG_vZb4Sr0fY2rmAw!2e0!7i13312!8i6656!6m1!1e1

Rhode Island Wiring Service, whos harnesses I've heard nothing but good things about, gets about $1300 for its B-model harness as well.... http://www.riwire.com/ ​

That's looking really sharp! When I was little I always had dreams of being an over-the-road driver sitting up in a nice Superliner cab! And I think maroon and black is one of the best combos for any Mack - looking foward to seeing the "finished" pics....

Sounds good. Now I'm always jealous when I hear a nice sounding diesel. Wish that's what mine had, but I was lucky to find mine in the shape that it's in... It's nice that you actually will be using it as a work truck. I wish I had an actual use for mine. It was a hard working truck back in its day, and then did farm duty for 8 years before I got it.

Thanks for all your feedback! I've been driving it a bit the last couple weekends, and am definitely getting a much better feel for what gear and/or what split I need to be in for various situations. As I'm worrying a little less about that, I'm finding that the shifts are getting a bit smoother as well, and I'm getting a better feel for where the main and the aux each drop in best - and it is definitely different between the two. Since I don't (and can't per law with antique plates) drive loaded, I'm now more interested in shifting it right for my driving conditions, which means driving it like a 7 speed (splitting 2nd on the start) with the occasional split for hill climbing. But I will still experiment with shifting/splitting through all the gears, just because it's fun to be able do it! ;-) gmerrill - like you, when I bought the truck, while I was waiting to get it towed home, I watched the Pappy video a couple dozen times so I'd have a good mental picture of what to do. I think it was a huge help and made the learning curve a lot less steep when I went out to do my shifting experiments. I'd recommend that to anyone who's just starting off with a triplex or quadruplex....

Maddog is correct, my main is on the driver's side, and the aux is on the passenger side. I've been wondering about that. Was that only done on gas? Or just the 401? Or single axle vs. dual? Anyone know what the logic was on that? And it certainly seems that the aux is a dream to shift compared with the main... It's a lot less picky, and there's a bit more bumping and grinding with the main. I was also wondering if the main was designed to shift at a higher rpm so that during a double-shift, where the main goes first, you shift at a higher rpm, then by the time you hit the clutch again, get the aux out of gear, clutch again, and move the aux to lo, it's already expected to be at a lower rpm, and designed to work that way..... That's why I wish I had a tach. I think in the Spring I'll get a cheap digital one and stick it on the dash to try to see what the difference might be between the two and what the sweet spot is for each transmission.

Thanks for the advice! You're correct to notice my hybrid clutching methods. Some of that is conscious as I'm experimenting with what works best for this truck. I drove a fire truck for years with a 5X2, and I could shift up or down with our without clutching with no problem, so I'm not exactly a stranger to the theory. But I know that every truck is a bit different, and I'm still trying to find what this truck's "g-spot" is for shifting. (I also think that gas vs. diesel makes a big difference) So I've been experimenting with no-clutch/single-clutch/double-clutch, and the double shift, as it's been pointed out, is still my biggest weakness. I think that I will, in fact, stick with a triple-clutching technique for that for now. And I tried the through the wheel method on the double shift, and it'll be a while before I try that again, lol!! I've discovered that I can shift pretty easily from lo to hi in the aux with no clutch if I remember to not push until the rpms drop (and I'm not using lo-lo at all), and I can downshift the aux with no clutch as well, but the rest will definitely require some more practice, probably more with the clutch than without! But it's been fun to learn. In the video, my purpose was specifically to experiment with split shifting. As bigdogtrucker suggests, I normally drive it essentially like a 5-speed, although there are some hills around here where my 150hp 401 doesn't cut it, and the poor thing can't get out of its own way, often requiring splitting at least one or two gears as I have to either split the upshift to keep moving, or split as I downshift while my speed drops going up a hill. I've read a lot of complaints that people make about the 401 being underpowered for road driving, and I'd have to second that. I'm not sure what the rears are geared at, but top speed downhill is about 47, and I know that it was a city truck, so speed was never an issue, but it's just sad to start out at the bottom of a grade at 45 and a quarter mile later be down to about 20 in 3rd lo!!

Awesome - Thanks!

So after getting the truck a tune-up and safety check, I took it down to our local State Beach parking lot (now that all the thousands of tourists are gone) to get a little practice with shifting, and after 3 practice runs, gave it a try on the road. There's a bit of grinding, but mostly because there's no tach, and I have to force myself to pretend it's loaded, and shift at a much lower speed that I really need/want to.... But on the whole, I thought this wasn't too bad for my fourth try of shifting through a few splits..... The file was too big to post here, so here's the YouTube link: I have the recommended shifting pattern for a B61 from a manual, but it's for a triplex. Does anyone have an actual manual page that shows the recommended shifting pattern/order for a quadruplex for both upshifting and down shifting? I know that for the triplex, they point out which shifts can be skipped, because the ratios are so close, and I'd like to know which ones those are.... Mike

Thanks - found it! After you hit edit, you need to go to one level deeper and click on "use full editor", then you see that option. Thanks again!

Looks like this is sold - Thanks! Is it easy to change the green "for sale" tag to the black "sold" tag like I've seen done? Or does that involve programming?

I did a little more checking, and according to one of Hendrickson's pdfs on their site, it's for an '89-'98 RD. Although if you do an actual search on their site by that p/n, it shows no results. Discontinued, perhaps?

When I recently bought my B-Model, it came with a NOS Hendrickson R-Model bumper that he was going to install on the B-Model, but I am not. As far as I can tell, it has not been mounted on a truck. They guy I got it from says he bought it after he got the truck, and left it in his barn for 7-8 years. All the chrome looks great, and there is a touch of surface rust on the un-chromed back side, as you can see in the picture. Looks like these sell for about $350 new. I'd be happy with $200. It's in southern RI. I do have access to a shipping dock, and if it needs to be shipped, I will pallet it, and you can make the truck arrangements. I guess you can IM me if you're interested, or my e-mail is jeeprider01@yahoo.com. Thanks - Mike
