doubleclutchinweasel Posted September 26, 2023 Share Posted September 26, 2023 It sure looks like the White/Hercules that FJDRILL mentioned. But I can't find anything about when/where Mack used those engines. Sure would like to know more about that. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Popular Post Geoff Weeks Posted September 26, 2023 Popular Post Share Posted September 26, 2023 Sorry I'M no help,but to agree it is not a Buda design. Conti was famous for casting a name into manifolds when a mfg bought their engine. I would guess may be Herc did the same? Never saw one like that either. Too bad we don't have Glenn or Mike H to pick their brains. 3 Quote Link to comment Share on other sites More sharing options...
Geoff Weeks Posted September 26, 2023 Share Posted September 26, 2023 (edited) Does seam to be a Herc. Here is a pick with vertical exh but everything else seams to "line up". I'd say 100% on the ID. Thanks to the poster who first said Herc. https://www.ebay.com/p/1523084881 Edited September 26, 2023 by Geoff Weeks Quote Link to comment Share on other sites More sharing options...
doubleclutchinweasel Posted September 26, 2023 Share Posted September 26, 2023 Now, if we can just figure out how Mack ended up with this thing! Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to comment Share on other sites More sharing options...

Geoff Weeks Posted September 26, 2023 Share Posted September 26, 2023 less than 100 hp, makes it unlikely to be even a yard goat. No air compressor seen, so what was it used for? They bought enough for Herc to cast their name in the manifold. A real mystery? Quote Link to comment Share on other sites More sharing options...
67RModel Posted September 26, 2023 Share Posted September 26, 2023 (edited) Something about this is strange. The second set of pictures the OP posted shows the engine has an over center hand clutch bolted to the fly wheel. I don't think this was installed in a truck. Possibly Mack had a contract with the government to build some stationary equipment. Certainly a puzzle.

doubleclutchinweasel Posted September 26, 2023 Share Posted September 26, 2023 I was thinking generator or some other stationary application. Like Geoff said, not enough power for much of any kind of truck. This one definitely has me puzzled! 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Geoff Weeks Posted September 26, 2023 Share Posted September 26, 2023 It definitely had a 2nd life as a power unit, but the vertical down outlet of the exhaust points to vehicle use. Most power units like the one I stole the picture of from E bay, have a straight vertical up exh. Any stationary use, I can't fit with the vertical down exhaust. Large fork lift? Airport tug?

BOBWhite Posted September 26, 2023 Share Posted September 26, 2023 Was Mack still producing railroad equipment as this time? Maybe it came off of some sort of yard shunt locomotive Quote Link to comment Share on other sites More sharing options...

fullfuel01 Posted September 27, 2023 Share Posted September 27, 2023 (edited) I heard that they had a kit to swap a mack gas engine to diesel. that was in the B model time. I have seen one in a B42, that was in my early age I can't remember exactly what it was, but it was odd The way the air cleaner stand on the intake, a carburetor can be mounted easily.

Geoff Weeks Posted September 27, 2023 Share Posted September 27, 2023 (edited) The low output would make me doubt that. In the 40's my K-7's were 21000 GVW and had more HP than that. I just can't see Mack putting less than 100hp in any truck they made. I admit I have no paperwork to back my statements on what Mack did or didn't do. What were Mack gassers in terms of Hp?

BOBWhite Posted September 28, 2023 Share Posted September 28, 2023 I think either Oliver or maybe White also used Hercules diesels in their tractors. I wonder if the manufacturer casted the manifolds with their name in or if the manufacture did. Did someone in the past do this just to screw with us?! 2 Quote Link to comment Share on other sites More sharing options...

Hp rated at less than 100HP . 1 Quote Link to comment Share on other sites More sharing options...
Geoff Weeks Posted September 28, 2023 Share Posted September 28, 2023 I am wrong! According to Wiki (and we all know they are infallible) the B20 came with en 291 gasser. at 107 hp, so a diesel of the same aprox displacement might have been installed in the smallest trucks. I stand corrected! 2 Quote Link to comment Share on other sites More sharing options...
doubleclutchinweasel Posted September 28, 2023 Share Posted September 28, 2023 A B20 with a small diesel. Now that could be. Still like to know more about this. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to comment Share on other sites More sharing options...
doubleclutchinweasel Posted September 28, 2023 Share Posted September 28, 2023 There were 124 B13's made. Odd number should have been a diesel. Can't find any information on what engines came in those. Also 131 B23's made. Again, odd numbers should be diesel powered. Same problem. Can't find a lot of info on those either. Considering the clutch lever mentioned, this could easily have been a truck engine, later converted to power a generator or a sawmill. Speaking of sawmills, I had a cousin who ran his sawmill off a 50's model END-673 out of a wrecked B model. Still had the 9-speed overdrive Duplex behind it. Even still used the parking brake on the output of the trans. Plenty of power and plenty of speed options! Overkill, you think? 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to comment Share on other sites More sharing options...
