What kind tests to see how much life my c11 got?

We have 2 c12s in the yard, they aren’t bad, but you know you are driving a small block

you are buying a truck that needs a motor and price should reflect that

 

Is it red or white?Frac trucks were red,the white ones hauled chemicals,their chemical division.They were trading out 10 year old trucks when I was there last year.If it's an 07 someone else has probably been running it.The red t800's on the frac crews had about 50,000 miles on them,15000 hours generally.They just traveled from well to well,a lot of pto time.The 2010-2012 t800's on the frac crews had bigger engines,some Cummins and a few Cats.They're good trucks if you can find one in decent condition.Southern Truck Sales in Houston sells them for around $50,000.
The white ones in the chemical division sat around a lot.

 

With 23k hours its best years are behind it.

Oil sample, coolant sample, dyno and blowby check will give you a decent idea of engine health.

Personally I wouldn't even bother spending the time and money to do those tests on something with that many hours on it. If its got decent oil pressure, its not putting compression into the coolant, coolant and oil aren't mixing and its not smoking like a chimney out the oil filler cap when you remove it with the engine running then I'd make an offer based off it needing an overhaul sooner than later.

 

That's an old good one,but not for sale

 

Short tractor, bet it rides like a lumber wagon

 

Best indicator is oil consumprion. Oil samples will be mostly useless without a baseline.

C12's are cheap and easy to rebuild. If you're staying local and the price is right, maybe.

Biggest issue with OF equipment, they are rode hard and put up wet, and air filters don't get changed near enough for the environment they work in

 

They ride nice,even on lease roads,but usaully pulling a frac pump or something heavy.

 

I bought an '05 Halliburton T800 with a C11 a few years ago from auction. 300K miles with 14K hours. My experience:

1. Everything worked on the truck - they are good on maintenance it appeared.

2. It was a beautiful truck once cleaned up. Dirty when I bought it and paint was faded, but buffed right back to shiny red.

3. If it's a typical Halliburton truck, you're going to hate how it's geared. Mine had 5.29's and did almost 2,000 RPM at 60.

4. I'm guessing it has Neway air ride (or possibly Hendrickson Primaxx). If it's Neway, you will love it.

5. The C11. If I remember correctly, it is the same block as the C13, but with smaller internals. It wasn't popular because it weighed the same as the C13 with less power, so most people went C13. Mine was set at (I think) 335 horse. I actually thought it was a great engine and ran well. And with the low gears, it had plenty of power. Also, I would not be too worried about blowby on an Acert Cat - it was common.

I sold the truck but regretted it. I would personally run it until you have a problem.

 

The alert I once drove got a new piston kit at 200k. Cat was famous for undersized pistons which broke the rings. Causing excessive blowby. And bad oil.

Construction trucks and pto trucks or tankers will have alot of idle time.
