Yeah we have multiple customers that use them just to load dirt into dump trucks and don’t ever notice they are actually derated until they get it where the pedal doesn’t respond.

Here is what I would do in this situation. Pull the dpf and clean it.

If the dpf is clogged, it will cause the turbo to be off balanced and it will leak at the shaft seals and can cause pressure down into the crankcase from the drain tube. You might end up replacing the turbo. Does it have play?

Also you changed the oil right?
It has slight play, nothing major. The normal slight click that u feel. It does not touch if u hold it over and spin it

The numbers don't lie. It's done just over 5k hours in 11 years. With an average of only 500 hours/yr it should be on time-based oil changes not hourly-based. At least IMHO.
Oh I know, but sometimes it'll sit for a yr in the shop lot. I have a loader that sat on the job for almost a yr now because of project changes, it has probably 150hr on oil. Im gonna sample it just to see what it come back as. It will be something to show boss also since he doesn't understand why it should be changed even though it has no time on it
