Any Old FL COE/Cummins Experts?

Its awfully low geared thats for sure. I drove an old KW that had 4.63. The 13 speed went bad in it and they replaced it with a 10. Sucker would pull a hill but it sounded like it was running 90 mph when it wasnt running but 55. It had a 290 in it.

 

Not sure if this is helpful or not:

 

Let us know what you find out about it....Looks like it was spec'd special, big power (for the day), geared low (as many were then) small fuel tank, and of course the Canadian spread tandem...Likely not an OTR tractor, but used regionally to pull heavy.....

 

You have a 123 braking system in there. Tractor only, trailer only, global everything.

You probably have a single air tank with brass valves on each end on the bottom. Open them up and get the gunk out of there. Let em drain several days.

I cannot help you with the engine. Whatever you got on there is what it is going to be. Don't forget to ensure your cab hooks are engaged when you are finished with working underneath of it. You will find them on the bottom rear of the cab.

It's nice to see these old trucks again, I spent time in several models of Freighliner COE, 83, 87 95. The 87 was the best ride, best working truck for the flatbed I had at the time. The 95 was a full out dollar truck 115 before the fuel pump quits providing fuel, maybe 120-125 on momentum under a load before the fuel pump starved out. And the lugging it could do would stop the rotation of the earth until under 80 mph. The 83 was my north eastern beater with a reefer, it was so crappy it was not much good for anything else thankfully. I think the boss poured more money into it than he made that year out of it.

I had other freightliner conventionals as well, but not until later in trucking. In those days young people did not get conventional they got issued the cabovers.

I think once you work on that thing and get it road worthy, you can do a little something with it. Although if that is what you call a fuel tank it's may be a air start air resevior to my eyes. Too small to be a fuel tank on that left side there.
