Is stalling the tractor an automatic fail on the road test?

Some people are lightning fast and they have to be to save a rig. Others will just watch it play out in full living color for better or worse.

 

That's strange because "lower" and "upper tach limits" change depending on whether I'm empty or fully loaded.

Would you move your "pasted" arrows depending on weight? If you don't move your upper tach arrow when fully loaded, then you will end up lugging the engine, which is a mortal sin apparently...

There are many reasons why a driveshaft fails. I had one drop on me while trying to slide tandems on a heavy load. The mechanic who came out to fix it on the spot said it failed due to loose bolts. He was a roughneck and not given to blowing smoke to save anyone's feelings getting hurt.

The above quotes belong in your signature so everyone might understand you better when you get all hyper-critical and know-it-all on a driver in training.

 

No, sorry but those RPMs are based on the engine makers recommendations you will find them in every owners manual. The RPMs DO not change because of weight.

 

Is this guy serious?

I realize I'm no longer discussing with a person but an opinion, so I'm reaching out to bystanders at this point...

 

Go ahead prove me wrong. Show me documented proof that a trucks weight effects or changes RPMs. Even in an XY shifter so called automatic this is still the case. Honestly I think you are confusing RPM to power. But the basic RPM does not change.

 

Here we have a By The (owners manual) Book driver who laughs at the FMCSR book which states drivers will keep their log book entries current to the last change of duty status.

 

I will try this again. If your engine is rotating at say 1200 RPMs at a speed in a gear that speed and RPM range will never change in that same gear NO matter how heavy you are. Weight can and does effect things like when the RPM speed an engine that is lugged will stall. This is correct. But those RPMs stay the same.

Would have been a very dark day if I had failed again as this was my last chance.[/QUOTE]

Huh? how was it your last chance?

 

I just happened to have this PDF link in one of my favs folder because of something else. In it you will notice 2 things. One there is the recommended RPM range for economy and performance. Also if you look close you will see the HP changes BUT THE RPMs do not. RPMs are a standard. NOTHING changes them but gear selection and speed. NOTHING!
