2000 mack cx613

I am a fan of the E7 engines for sure as reliable as they come. I have worked on a couple of those trucks with the cruise problem you are describing. Found the brakes lights came on when you set the park brake. Ecm thought the brake pedal was applied so cruise wouldn't activate. It was an air problem seems like a diaphragm blown in the tractor protection valve

 

460E is econodyne it is 460 hp hotter 460 file for that year is 460xt 490hp good luck getting it from mack there are other options injectors turbos and tuning upgrades if you need it stock 427 has a better torque curve than a 460e and out pulls them. if previous owner put a cam in with the over haul that would be a big plus. also if he did it at mack it would have some good warrnty on the over haul

 

no hard parts in the motor Mack only put them in all Mack trucks from the factory and the don't like handing the file out due to emission compliance. a 460 is 460hp at least but some had a weak torque curve the 13spd will greatly help you 427 are E7 427

 

True, just make sure the tranny can handle the torque. Mack engines are Reneaux and metric. Mack quit making their own way back when they couldn't get the emissions right. Still a good engine.

Once you get her home check some key points......look under radiator...those bushings should not be flat. Make sure the radiator strut bushings are ok too. If you need something send me a PM....I have a bunch of new stuff left over like hood guides, pigtails, king pins etc.

Check those water tanks too.....top off the one with the cap. Grab that Horton and make sure there is no slop......Get you some breakers too, fuses as needed / used.

One hard lesson I learned is proprietary parts. Many things MUST come from Mack....stupid stuff too like A/C expansion valve, hoses, etc. Other have look a likes that just don't work. The fan switch is another one.....burns up about once a year. Happens to all of them too. Wiring too lite I guess.

Happy trails with your dog.....

 

Ezrider, I can't remember when they switched, but if that E7 still has the Bosch-style fuel system (seperate lines off the pump for each cylinder,) they don't return much fuel, and you'll need to account for that up in your part of the world come winter. I had a '97 with a 454, and I've always wished I'd have kept her around, I kinda miss looking at the backside of that gold bulldog. LOL

 

renault did not make the e7 they was made in Hagerstown Mack Powerplant factory, which is still kicking out motors today. renault exported it to overseas for there cab overs


Bosch inline pumps stoped in 98 my 01 with eup returns a ton of fuel no jelling issues in minus 10

 

Ok well I had a Renault in my 98 CH per Houston Mack along with the $4100 Bosch injector pump. The quote I gave came straight from Mack when I asked why the dog was metric.
