Bumper To The Back Of Cab Of A Superliner

[ThaddeusW]

I am looking at a superliner with a really long wheel base. I want to know the bumper to the back of cab length and the center of the front axle to the back of cab. Sounds crazy but I want to put a box on it and want an idea of the overall truck length. Also how difficult is it to convert camel back to air ride?

BBC is 121"

Bumper to axle center is 28"

mine is 125" bumper to back of cab. You were also asking about the Trimatic coupling a while ago, they are made by WABCO. if that is of any help, much more superior to your old 1940s glad hands???.

mack made two different bumper arrangements. the standard was flush mount and the other was extended mount. that's the difference between the two measurements.

Nigel,

I looked up the coupler on WABCO's websit and they called it duo-matic. There also seems to be a second type that has a third port for an auxiliary air line called a triomatic. I like how you operate the coupling with a lever for quick connecting of all lines at the same time. I wonder if they are available here in the US.

I can send you the 2 parts that make up a coupling, the main tractor part accepts a trimatic from the trailer or a duomatic from the trailer. and there is the end that is connected to the trailer at the end of the hoses.

you can mix and match then and they are idiot proof, (have to be for us colonials)

let me know if you want a set. I would say that 98% of new zealand rigs usde this type of Coupling.
