41chevy Posted August 29, 2010 Share Posted August 29, 2010 One of our members had this in a post from a recent show, Never saw a B with this type of nose. Is it factory and anybody know what powers it? Or is it a set back axle? Also got th new drive chains for my AC today.......now just need 1 adjuster and 1 drive sprocket.

Underdog Posted August 29, 2010 Share Posted August 29, 2010 Looks like maybe a B-71. Quote Link to comment https://www.bigmacktrucks.com/topic/15506-long-nose-b/#findComment-62589 Share on other sites More sharing options...
HK Trucking Posted August 29, 2010 Share Posted August 29, 2010 Looks like maybe a B-71.Yup.Longer hood to make room for a Cummins, with steer axle in the same location as a B61, rather than set forward like a B75.

theakerstwo Posted August 29, 2010 Share Posted August 29, 2010 In the mid 60s i remenber two of those coming in and one had a engine repower with a 6 71 DD in it . The other had a cat repower way before i remenber trucks coming from the factory with a cat engine in it. It was a equipment cat engine.The best i remenber the only thing different from a B 61 body was the rad and cowl was exstend forward.

Rob Posted August 29, 2010 Share Posted August 29, 2010 Yup.Longer hood to make room for a Cummins, with steer axle in the same location as a B61, rather than set forward like a B75.Kinda the same but different I'm doing with my white B61. I've "split" the grille shell and going to weld in an extension of five inches to bury a CAC, and a/c condensor behind non functioning, cable operated shutters. The engine is an E6-350.

RobCool I like that ideal but i looked into that with mine years ago and ended up installing the Cac on the front out side . The fan is so short on a B61 that even when you do get the speed up on it it is so loud whith noise. I used a 6 blade fan on a swister clutch and it was even more louder.The problem with the narrow rad is the short fan has to be used.

Mack458 Posted September 14, 2010 Share Posted September 14, 2010 Mack manufactured some larger pump B models that the 707 engines could not power. The noses were lengthened to accomodate a Hall Scott engine.

The noses were lengthened to accomodate a Hall Scott engine. Scroll down this link to see one. http://www.lastresortfd.org/museum.htm mack458I don't recall seeing one of those either. Do you know the model number? It appears to be built with the same parts as a B-71.

Yoos Brothers Construction Posted September 18, 2010 Share Posted September 18, 2010 That's a B-21. Mack only made 9 of them. All 9 were fire trucks. Basically it is a B-75 with the B-71 extended grillso they could fit the big Hall-Scott under the hood.

This is a Mack model B-71 which came out in 1953, when all of the new B series came out. This model may have the Cummins NH-220. The early Cummins 673 CID six had a 4-7/8 in bore by 6 in stroke, the successor the 743 CID six had a 5-1/8 in bore and 6 in stroke and the successor to the 743 CID six was the Cummins NHC which were 5-1/2 in bore by 6 in stroke with 855 CID. Foe a short period Cummins made the Super 250 which displaced 927 CID, same 5-1/2 bore but deeper stroke/sleeve. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/15506-long-nose-b/#findComment-551172 Share on other sites More sharing options...

mattb73lt Posted May 8 Share Posted May 8 If you look at those B21's closely, they have both the extended radiator of the B71 and the fender to cowl extensions of the B73/75's. Probably the longest nose B's ever built. Those Hall-Scott's are just huge. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/15506-long-nose-b/#findComment-551349 Share on other sites More sharing options...
