Jeff M 86 Posted April 25, 2020 Share Posted April 25, 2020 You're talking a significant project here, which will take either excellent mechanical/fab skills on your part or a ton of money---and a lot of patience. Quote Link to post Share on other sites
steelman 133 Posted April 25, 2020 Share Posted April 25, 2020 Mad dog, The little B I have is painted Mack green like Tackaberry's. George sold it to a fellow on Cape Cod who had it for years. He had an electric over hydraulic eight foot landscapers dump body put on the rear. He had a little accident with it and dented the front fenders and radiator surround. Sent it back to George to repair, put a patch panel on the bottom of the passenger door and repaint. At some point he decided to sell it, and I bought it and brought it home last year from Maine. I pulled the dump off and have a stepside body going on it like Tack's and the red one. I am repainting it and freshening it up. It runs well (5.9 Cummins and automatic) and George put a over,under and direct brownie box behind the auto. You can pull stumps (or trailers) in underdrive, and in overdrive it will really cruise. I am 6', 265 pound, but fit in it easier than I do in a regular B model. Very comfortable, and VERY COOL looking. People notice it. I plan on making it my daily driver after repaint. Re the fenders, he made a lot of cuts and fitting to make them look correct for the smaller tires. The cab is narrowed 4 inches, and the radiator shroud is also narrowed and chopped a few inches. The two front running lights were eliminated when narrowed. The truck is amazingly well proportioned, like 5/8 scale. George did a wonderful job building these. He told me he did six Macks and two Pete's. I am recovering from surgery right now, but would be glad to share Info on it after I recover. Send me a PM with your email..I have an integral sleeper I wanted to modify and put on another little B. The cab is too far gone to restore, but I looked at stretching it and creating a four door. I have the chassis and everything ready to go. The amount of money and time it takes is substantial.. I could probably finish it if I live to 150 years. Quote Link to post Share on other sites
DKWIDK 1 Posted May 12, 2020 Author Share Posted May 12, 2020 Question: Would an E7 engine and complimenting tranny (say a Fuller 7- or 10-speed) fit into a B-61 without needing significant alterations? What barriers or pitfalls should be expected? Thanks, DKWIDK (Don’t know what I don’t know) Quote Link to post Share on other sites
Maddog13407 2,199 Posted May 13, 2020 Share Posted May 13, 2020 steelman I looked at your truck on a flatbed this year at Macktrucktoberfest last year. again wish I had the dimensions to cut down the fenders proper Quote Link to post Share on other sites
steelman 133 Posted May 16, 2020 Share Posted May 16, 2020 Mad dog, Give me some time (4+/- weeks) to finish recovery, and I will try to get you what I can off my truck. I had a bad accident, four surgeries, and am now recovering (last nine weeks). Right now I cannot even get to my shop to take a picture. I am going crazy sitting still, but nurses and physical therapy just about every day for a little longer. Send me a PM and I will send info as soon as I can.

DKWIDK 1 Posted May 30, 2020 Author Share Posted May 30, 2020 Guys, thanks in advance for your patience with me. I’m still trying to work my way through the planning phase. Here’s a variation of a question I asked about a month ago: Will an E-7 engine with its turbo plumbing fit onto a B-61 frame (without modifying the bodywork)? Thanks very much, DKWIDK (Don’t know what I Don’t Know) Quote Link to post Share on other sites
JoeH 432 Posted May 31, 2020 Share Posted May 31, 2020 I suspect it might, the R model has been used with engines from the same era as the B as well as the E7. Chassis Mount Charge Air Cooler might not fit though. Perhaps the R model firewall was altered for the E7, but I'm not sure. It's only a 1 liter displacement change.

DKWIDK 1 Posted June 12, 2020 Author Share Posted June 12, 2020 Guys, I need your input!! I’ve come across a ‘56 B model for sale that has a nonturbocharged diesel. I’m not sure which of the Mack engines it is, but I know it’s a diesel, and it has a Triplex tranny. The guy that’s selling it knows even less about Macks than I do. A friend of mine is acting as the buyer because the truck is in another state. This friend has SOME knowledge of diesels and is a wealth of knowledge in other aspects of older vehicles. Here’s my question: Would y’all be able to give me some quick tips of what to look for to pass on to him? For example, what should the oil pressure be at idle and in the middle of the power band RPM? What symptoms would be a deal breaker, etc? This is where I really need to hear from you guys that know these trucks like the backs of your hands. Thanks so much, IDKWIDK (I don’t know what I don’t know) Quote Link to post Share on other sites
h67st 1,269 Posted June 12, 2020 Share Posted June 12, 2020 If the engine is original, it should be a 673, with 160 to 180 hp. For me the deal breaker is excess rust in the cab and sheet metal (or rust that's been covered with bondo). As far as oil pressure, I'll have to let one of the more knowledgeable guys answer that one. Quote Link to post Share on other sites
davehummell 448 Posted June 12, 2020 Share Posted June 12, 2020 If it is an early end 673 like mine is i had a hell of a time finding rod bearings and rings I pulled that engine and put one in that i can get parts easier. Quote Link to post Share on other sites
DKWIDK 1 Posted June 16, 2020 Author Share Posted June 16, 2020 Thanks for the input h67st and Dave. I appreciate your insight. Next question: How hard is it to switch out the differential gears for a taller ratio on an old B- model? I won’t be pulling a load, and I’d like to see about having a higher top end on the highway. Thanks! DKWIDK Quote Link to post Share on other sites
DKWIDK 1 Posted June 30, 2020 Author Share Posted June 30, 2020 Hey guys, I’m hoping someone might have an answer for 2 questions pertaining to a B model with an END 673 (non-turbo): 1. The vehicle has been converted into a pickup truck by an unknown previous owner. I’d like to see about changing out the pinion and ring gears so it can run at highway speeds. I plan to drive it unloaded, but might occasionally pull a 20’ bass boat unless the esteemed panel recommends I don’t. Any suggestions for the new ratio and a good way to go about doing this? I believe it’s a 4.60 rear end now. 2. Does anyone know the outside dimensions (L x W x H) for the END673? Thanks very much! DKWIDK Quote Link to post Share on other sites
j hancock 13,667 Posted July 3, 2020 Share Posted July 3, 2020 Ratio of 3.87 or 4.0 with direct trans on 22.5" or 4.17 direct on 24.5" rubber. Different ratios if you have an OD trans. 43" X 15" X 39" T. I have already started the long weekend and used my Harbor Freight tape measure so the info is worth exactly what you paid for it. Didn't help that the bees woke up as the hood was being propped open by my head. Measurements do not include manifolds, flywheel housing or fan. Quote JimIt doesn't cost anything to pay attention.
