Bigdogtrucker Posted March 14, 2012 Share Posted March 14, 2012 I have an original 1960 B75,s/a tractor.Most 75's i've seen over the years have been tandems.Any way to find out how many were made of each?

Brian Blaylock Posted March 15, 2012 Share Posted March 15, 2012 If the first three numbers of your serial number are B-75 T there was 113 of them built in 1960 Quote Link to comment https://www.bigmacktrucks.com/topic/23848-sing-axle-b75s/#findComment-107612 Share on other sites More sharing options...

Bigdogtrucker Posted March 16, 2012 Author Share Posted March 16, 2012 If the first three numbers of your serial number are B-75 T there was 113 of them built in 1960It's B75T followed by a 4 digits,here's a few more pics.The truck is very straight,and not a lot of rust.I was supposed to get it a few years ago,but some things came up.Lucky for me the owner saved it for me!Any idea what this truck's value may be?(not selling)Fully rebuilt 673 with low miles,20 speed Q-Box.Aluminum tanks,hoods,shell ect...I'm the third owner.

Shawn Barrett Posted March 16, 2012 Share Posted March 16, 2012 If the first three numbers of your serial number are B-75 T there was 113 of them built in 1960Well Brian says only 113 in 1960. I personally haven't seen many....Seems like it may have a "rare bird" factor to it. Maybe we should call on Superdog Mike again.....The man seems to know a thing or two about rare macks.

Maybe we should call on Superdog Mike again.....The man seems to know a thing or two about rare macks.I've never seen a breakdown sheet on how many of each where built,where'd you find that,Brian?That would be some great rainy day or late night reading.Another thing you want to remember,back then there were alot more single axle trucks built,do to varying weight/length laws.Also alot of tag axles in use then,lot of operators couldn't/wouldn't justify the extra cost of a twin screw.

Numbers should be stamped on both,trans should read TRQ720 or something similar.Rear ratio should be stamped on a small flat area on the pumpkin.

yarnall Posted March 17, 2012 Share Posted March 17, 2012 While Mack kept track of how many of each model was made they did not keep track of thing like number of axles and cab type. The only way to figure out how many single axle.B75's were made would be to go to the Mack museum and look at the built sheet or serial number for.each one. At least with axle number you could look at the serial number list and everyone with just a T suffix is a single axle(also lt). If you want to know how many B67's were built with a concave cab you have to look at every B67 build sheet.Very neat truck. I would love to have it. Value is a.little tough, but I would guess in the 5000-8000 range if it runs well. Maybe a little more.if someone really wanted it.Mike Quote Link to comment https://www.bigmacktrucks.com/topic/23848-sing-axle-b75s/#findComment-107965 Share on other sites More sharing options...

If it was converted or if some actually came that way. I think mine is about the only B67 I've ever seen with a standard cab as opposed to the concave.Rumor has it that my father converted one of his Bs for one of his drivers who was a BIG BOY. I don't know if this is the one or not or even if my information is scewed.....However for a man that had twenty plus B models at the time...I can't imagine anyone taking the time to cut and section a B67 Concave to a standard configuration when you could just put the man in one of the many B61s he had.Dont see any dead giveaways on the outside and havent looked behind the headliner for clues but it is on my mind....

Brian Blaylock Posted March 17, 2012 Share Posted March 17, 2012 The concave cab was an option on several B-Models not just B67s I have seen B61 with concave cab and B67 with straight cab Quote Link to comment https://www.bigmacktrucks.com/topic/23848-sing-axle-b75s/#findComment-107983 Share on other sites More sharing options...
vision386 Posted March 17, 2012 Share Posted March 17, 2012 AAA Transport and Mushroom Transport both had B-67's with both standard and concave cabs,same thing with the B-61's those are about the only two companies i remember running both types,but MOST B-67's i've seen were concave cabs......................................Mark Quote Mack Truck literate.

yarnall Posted March 17, 2012 Share Posted March 17, 2012 We have a B66 with a concave cab and one with a standard cab. It is just an option. I was using that as an example like single axle versus tandem axle. They don't have anything to do with the model. You could have gotten various models with various options. The model implies certain things like engine and hood length, but not number of axles or cab style. You could.put sleeper cab in with the cab options. They were not kept track of either. Certainly there are many people.on here who know a lot more about this than I do. If i had more.time I would go to the Mack museum and figure some.of these things out. It would be a fun rainy day project.Mike Quote Link to comment https://www.bigmacktrucks.com/topic/23848-sing-axle-b75s/#findComment-108040 Share on other sites More sharing options...

Bigdogtrucker Posted March 17, 2012 Author Share Posted March 17, 2012 Didn't have a chance to climb under it to get any numbers,here's a pic of the gear shift tag.Any info/advice on this trans would be great.

Its a quadruplex. You'll be shifting the compound 4 times in every gear of the main...give or take. Probably not necessary empty. Theres a plethora of possibilities hahah. Theres enough gears in that or should I say torque multipliers too pull down the house! Good luck learning how to master that beast. Go and order this DVD that the old timers put together for us....It'll help.http://www.longroadpro.com/2stick_frameset.htm Quote Link to comment https://www.bigmacktrucks.com/topic/23848-sing-axle-b75s/#findComment-108171 Share on other sites More sharing options...
Bigdogtrucker Posted March 17, 2012 Author Share Posted March 17, 2012 I had an ACar with a 5x4 and had a B61 with a duplex,so shifting won't be a problem.As far as Lo-Lo,wouldn't that be mostly used for starting off with a heavy load?
