Freightliner on the high side?

I suggest you go to a dealer - a new truck dealer, sit down with the sales person (buy them a good lunch) and ask questions and also have them spec out the ideal truck for you - let them explain what it all means.

Why?

Because I think you would become confused and not really getting a few important things like it doesn't matter what make the truck is, the drive train is the important part. I call what you are asking - nitpicking (no offense). Get a 13 or 18 speed, the dealer will tell you what's a good ratio to have in the read for the work you are going to do, but remember that the larger engines have a specific sweet spot, and you want to have that for the environment you are using it in, so ask the dealer about that and where it should be for different engines.

ALSO when buying a used truck, don't think it is like buying a car, it isn't. You have to go through a process to see if it is ok to be put into service and if there is a risk of break down. This includes a dyno and blowby, having an ECM dump and talking to the dealer for that truck (freighliner if it is a freightliner, mack dealer if it is a mack) and have them pull all the records on that truck and print them up, this should include the actual order of the truck with all the specs and serials numbers and any shop work in the system.

AND that said, here is a bit of important advice, there are more trucks chasing owners than there are owners chasing trucks, so be selective and take the time to pick out the one that will costs the least amount of money to run and not break down.

 

Has he heard of a 2.85 gear?

 

@sdaniel lol I don't know. What's your take on it?

 

Seems to work.

 

@sdaniel whats that?

 

What's my take on what?

Your uncle?

The 2.85:1 ratio?

 

That is a screen shot of the computer in my truck. The top number is instant mpg. Next number is daily mpg. Lower number is mileage for the day. All reset at midnight. Pull doubles , two light loads running I81 that day.

 

@sdaniel oh okay. You have 2.79 rears?

 

Why'd you have to replace the clutch? What led up to it?

 

Double clutching was most likely the culprit. I have hydraulic clutch, and when I had a service done. I had my mechanic check underneath for a squeeling sound. Pilot bearing was no good and I also had a input shaft, and flywheel replacement. Had them replaced the rear main seal as well.
