Mechanical motor

Mechanical has a rod from the pedal to the pump. Mechanical will burn itself down if it's not set right or if you don't know when to take your foot out of it.

The electronic uses sensors and an ecm to control the fuel. They are generally more forgiving and better on fuel.

 

I have a 3406b and I love it. No electronics on it at all. Nothing for the ELD to connect to. We use Big Road app.

 

I'm not a cat guy... but generally the differece between mechanical vs electronic...

Mechanical- easy to work on, injectors wayyy less expensive, will run and run and run and run and run and run and run until real mechanical problem, easy to diagnose, can coast downhill to start- no electricity needed.

Electronic- when problems come, $$$ will be spent. An electrical problem, sensor, or other nonsense that is not needed whatsoever to run a mechanical engine, will leave you on the side of the road. Tow bill, shop bill, downtime. Expensive computer, sensors, wiring... Did I say $$$?

Check the forums. My favorites are guys with electrical problems that have spent thousands of dollars (3, 4, 5, $6,000 or more possibly) trying to find an electrical problem, while the truck is down and the bills grow.

Even if you don't work on your own truck, the mechanical has less to go wrong with it, and is much more dependable and less expensive to repair. Think of it like this- a mechanical engine is the same as an electronic without all of the expensive, unnecessary bs added to it.

I don't think the small fuel savings is worth that kind of aggravation if you're a guy with one or two trucks. But don't listen to me- check the forums.

Good luck.

 

Man, I agree with you !
