Overhead was run in 2020.

Probably set at 425hp or so

Cummins reman inj in 2017

Starts well but it's warm here. Slightl white smoke when cooler Temps. Was making little more smoke under load before break but not terrible. U could see the exhaust from a distance bit was very see through.

It has plenty more power to go past 1000f. Was cracking turbo and exhaust housings so we put the egt and been good until now. It maybe an old injury that finally showed itself.

If we have to run 900 or less the tractor will be crawling along vs the stx. It runs about 1/2 to 1 mph slower.

It's never run hot or showed any signs of issues.

The cam is bad on #5 & #1. Just pitted Probably from age.

Squirters were replaced in 2017 with rebuild. Good oil pressure before teardown.

Looks like we will have to build an air to air cooler for it.
