Cummins ISX hours & Miles

Not really sure, but for reference that truck has the equivalent of 471k mi with 20k hours,my truck, all be it a road tractor, has 713k mi and 15k hours. So, the hours seem high, maybe lots of idle time. Maybe that's normal for vocational use. Pull the valve cover off and have a look at the top of the motor. Check for cam wear, sooty oil all over and so on.

 

I overhaul my 2005 isx with 28,000 hrs and 896,000 miles that's the life my truck used to be from company call cfi

 

Bearing rolls are a thing of the past...... Just save your money towards a inframe when the time comes .

 

Bearing rolls are a thing of the past? That's horrible advice. Cheap insurance for sure. When you spin a bearing and screw the crank and the block there goes the chance of a basic Inframe. 1k to roll some bearings at 500k is cheap insurance and a good idea.

 

He don't need bearings at 20,000hrs

 

On the newer engines they are a waste of time/money. Multiple people (engine rebuilders) have told me this. One works for cat and the other a kw dealer.

Run it till you have symptoms and then do it all.....

But do as you will $$$$
