curioustom Posted October 3, 2005 Share Posted October 3, 2005 Hello!New to forum but have visited often. Longtime Mack fan with some basic questions.What do the model names mean? For example B61, B81SX etc...I am very partial to Superliners and LTLs. Have seen numerous pictures of B81 SXs, or anything with the flat "gravel pit" fenders. Any info will be absorbed like a sponge, you guys have so much knowlege!Are there any publications availabe with this sort of info?what model is this in the attachment? (if I did it right)Thanks in advance! Quote Link to comment https://www.bigmacktrucks.com/topic/408-mack-model-designations/ Share on other sites More sharing options...
Barry Posted October 3, 2005 Share Posted October 3, 2005 Hello and welcome to BMT! Glad you joined up! Here is some info I grabbed from www.oldmacksRus.com Chassis Versions What do all the letters mean? These are the basic letters used B - school bus chassis C - flat face cowl for the addition of a delivery body E - built for export F - fire truck chassis L - light weight or weight reduced by using aluminum components P - platform chassis (single axle straight truck) R - right hand drive. This designation was started in 1964 but right hand drive available prior as option. S - six wheel chassis (tandem axle) T - tractor chassis X - severe or extreme service chassis Combine any of the basic letters to get a different chassis PC - flat face cowl platform chassis LST - light weight six wheel tractor chassis SX - six wheel extreme service chassis STE - six wheel tractor chassis for export RX - right hand drive extreme service chassis These are some odd versions BD - school bus - no idea what the D means. Little more than 100 built 1955-1956 EWX - don’t have a clue on the letters but the picture shows a mean looking B83 built in 1965 with 3 drive axles SX-C - six wheel extreme service chassis, may have been built in Canada SX-M - six wheel extreme service chassis, no idea what M stands for T-HS - tractor, don’t know about HS T-M - tractor, don’t know about M TPB - tractor piggy back Now the fire truck combinations! The good guys at the Mack Museum and Harvey Eckart had to do some “head scratchin” on these CF - fire truck with Chrysler Corp. drive train FA - aerial ladder fire truck FC - fire truck chassis without fire body. This designation started in 1965 FCD - fire truck chassis with diesel engine without fire body FD - fire truck with diesel engine. This designation started in 1964 FMD - don’t have a clue. Only built in 1963 FSW - six wheel (tandem axle) fire truck. This designation started in 1958 for fire trucks but had been used in trucks prior to the B model series. FT - fire truck tractor. This designation started in 1965 but fire truck tractors were also built before this date. Hope this helps!

Freightrain Posted October 16, 2005 Share Posted October 16, 2005 I'd say the picture is a B81SX (of sorts). Variations could apply, but that's what it basically looks like.Tall standing, 24" rubber, long hood gives it away. Quote Larry 1959 B61 Liv'n Large......................
