Picking my own freight baby! My journey to & of being on Schneider choice, the Adventure & Numbers!

I find that hard to believe too. Bruce over at Pittsburgh Power will say over and over he'd much rather pull a grade at high rpm than lug it. Much easier on the engine.

 

It's in the manual, and the DVD that ships with the truck.

Not really that absurd when it comes to warranty.

I have a Fitzgerald Glider. They build their trucks and set the governor at 1800rpm. You can change that if you like, but under their warranty, operating the truck at over 1800rpm can and will void the warranty. This is a series 60 though, intended to run at a higher rpm that newer Detroits or the PACCAR.

With the PACCAR engine, the torque curve dropps off at 1400rpm, 1300 or so on the 2015 and newer trucks. They specifically state that the engine is not intended to be operated at rpm's above 1500.

 

Agreed. However, Bruce is also old school and deals more with older style engines. My truck was dyno'd there, and being an older 12.7L, even that engine reaches it's torque peak at 1400 rpm. I prefer, as they recommend, getting it up to around 1500 to pull a hill though. From there, I let it drop to around 1300 before splitting to get it back into the 1500 range.

 

Your looking at a week minimum

 

Wow, I totally messed up on my RPM statement. In my 2015 (2014 build), it said 1500rpm. In the most recent numbers, they give a maximum loaded RPM of 1900, and only state that operating it for more than 30 seconds below operating range under load will cause damage.

Still designed to be low RPM engine. Peak torque is reached at 1000 rpm, and depending on the programming, begins losing that torque at 1200rpm.

 

I'm scared to jump into this, but I was always told it's HP that pulls a hill not torque. I have a Mack and I was told for longer hills, keep it up near peak HP. (1800) I know when I drove a newer Casscadia with a DD13/15 is it governed at 1550, so it always felt like it was lugging.

 

True that! Idk what your motor is rated at, but some of those VA/ WV hills have me down to 25-30 fully loaded with my crapforce 450hp

 

Mine always seemed to pull best down in the 1000-1200 range. I say best, because it never really pulled well, not as far as what I have been used to.

Being a 13 speed, I expected to do better in the hills than I did with the used Cascadia I lease purchased for a year. That said, the Cascadia would pull circles around my t680.

With either of those trucks though, you don't get to see what they are truly capable of. My previous Cascadias were with a company pulling tankers. Small outfit, and the trucks were turned up completely. The difference in HP and torque is night and day. They run so much better, and so much more economically, when they are not restricted at the ECM.
