30,000 hours- curious how many others?

That, sir, is a lot of hours. How many miles?

 

Our 2007 C15 Acerts range from 27-32K hours. We get a lot of PTO time, so hours are more than most and many of our maintenance items are based on hours rather than miles. For us, around 30k hours is pretty much time for an in-frame. We have one at 726,000 miles and 32,000 hours that has not been in-framed yet.

 

My 07 is at 855k and around 22k hours. Never been touched other than an actuator or two.

 

mine has 27k but was in framed at 525k miles, has a total of 1,082,000 miles.

had a Pete with a 12.7 that's still running around with about 1.5 mil miles never been touch, used to get 8 mpg and never smoked through the breather, which is rare for a Detroit at any amount of miles.

 

Does CAT ID have engine hours info somewhere in it? I would have to look you have me curious. It has a lot of info I just scroll thru and never really use. I keep it on water temp whenever the truck is running and go by it to turn the fan on/off. I also use the maintenance feature - reset it when I do a pm and it reminds me before I hit 12,500 miles that it's time. CAT recommends, I believe, OCI's of 300 hours for normal highway operation and I don't think I ever go that high. Really have no reason to keep up with hours so I don't.

 

I reckon I would easily have the record here as my 1980 KW has done over 5,000,000 kms with over 80,000 hrs on the CAT 3408 engine. Had 3 in frames with new liner kits/heads, bearing rolls approx every 700,000 kms, original crank with no wear patterns on journals, no electrolysis in block.
Had the truck 20 years with two previous fastidious owners. I change oil at 9,500 liters (5,900 gal?) fuel burn, and CAT SOS sample oil every oil change and change and test coolant regularly. Also carefully warming up and shutting down engine helps a lot imo.

 

Back at the last fleet shop I worked for we had a pair of Western Star steam trucks ('03 w/ C12 I think). Both around 24,000 hours and about 40k-60k kilometers. They spent much of their lives on a handfull of locations running about 22 hours a day for months on end.

 

I'm at 38000 and 748k
