When to expect a dropped liner cm870 - tree98 - 04-02-2018

Found a good deal on a used t800 that I would like to buy. It's an 07 cm870 with 405,000 mi. It runs pretty good, not sure who did the demandate but aside from that I'm wondering if it has much life left in it before it's gonna drop a liner? Isn't the magic number around 435K mi.? Do you guys do inframes on these motors at a certain mileage?

Turns out the seller says it still has the mandate. I just assumed it didn't.

I don't know a whole lot about the 870, but I would think things like it's power settings and abuse history would play more of a role than anything at 435k...

It's 525 hp

What was it used for? What lanes did the owner run? Why such low miles? What can you tell of the owner, do you think he would beat it up? Can you scan the ecm for more info? Was it ever tuned? Maintenance history? Is Claudia scheffer still hot? All necessary things to know.

How many hours? PTO?

It's a flatbed, been hauling lumber locally all its
Life. Probably had 30 different drivers over the year's been beat on a little more than likely. It's pretty cheap that's why I'm interested in it. But if it needs an inframe right now then I might stay away. I guess I need a crystal ball to know that though.ill see if he'll let me insite the ecm.

870 nowhere near as problematic as 871 and up. Especially at only 525 hp. I see 87ps come tgru my shop with more miles than anytbing with the least issues. Not uncommon to see 800k+ miles set at 565 and up hp. At least that I see. Theyre lower compression than 2250/2350 and I swear the block material is far harder than 871s and up
