3 trailer road trains can be made legal up to 130 tonnes..

Bigger combinations go onto permits.

Yes we haul some heavy stuff out here..

Biggest weights i have seen running are right in the high 300K lbs range, in the Iron ore mines.

Aint no cumapart doing that job.. Its Kitty all the way.

 

Cats can't even do 60000kgs over here. It's Volvo and Scania all the way..

 

u need to recalibrate the ecm.....but u wont get more thn 525ish horses........ str8 piping it will give u lots of power and it will run cooler...... more thn 500hp u need to upgrade engine parts..

 

No, road trains arent off road.

Some of our roads are Graded dirt, but its all on road.

The off road stuff is different and larger again.

I cannot be bothered looking up the photos, nor can i be bothered re-interviewing the leading hand at cummins, but they are reknowned out here for coming apart under pressure.

im not talking failure, im talking catastropic destruction. and it was common enough for cummins to recall EVERY motor for the early attempt at a fix (monotherm).
This helped, but didnt solve the issue.

our max roadspeed for the heacy stuff is 90 kph, which is 56 mph.

you want to explain to me just how gearing, transmission and HP can affect how these engines break the gudgeon pin retainer clips? reguarly?

the heavy haul guys run 4.56 or 4.88 gears to pull the weights. Gearboxes are 22 series, and as far as im aware, thats pretty much as big as they come for road trucks and HP? you need every one of the 620 that the signature produces, along with all the big cat hps..
Detroit hasnt been too popular for roadtrain guys for a while.

Most of the guys i know are cat all the way, due to the reliability these engines have offered them over the other brands.
One even went so far as to repower with a cat..

Speaks volumes really. but you dont have to believe. i wont loose sleep if you want to believe something else.

 

I really do not see what you guys down under do any different than most people do up here in the US, but it is true you all have higher warrenty claims than we do for Cummin's products. I have tried to make all the ones I drive go cato but I can not get one to do it.

 

Well for one the weight they run down under is way more than 99.999% of our trucks will ever see here in America. This alone can cause major wear to a motor over the long run. Throw in other differences like terrain, climate, and sometimes fuel quality and the difference is even more glaring.

 

Eaton Fuller has this neat private road course that they test trucks on. It has grades up to 15% on it. They pull over 200,000 lbs with some trucks up there to test transmission. Why is it that I have not heard of a major failure up there with a cummins product? That being said I have not heard of a Cat having a major failure up there either. I can't answer that and I doubt you can so the weight and type of terrain is out of the question.
