3508 Cat Gen Set with 80,000 hrs
We have owned several 3508 Cat gen sets and work on them several times a year.
We have never seen a 3508 last that long. More like 25,000 hrs if lucky. Generally they are rated 1200 Hp @ 1800 rpm and some have been brought up to 1500 HP but you will see them make vents in the blocks more frequently at the higher HP range.
The engine that we are impressed with is the 1200 HP range is the Cummins QSK23. This engine was derived from a Komatsu in a joint venture between the two companies. We have several in the 13,000 hr range and they have performed flawlessly. Burn one gallon of oil between oil changes.
The 23 liter Cummins seems to do everything the 34 liter 3508 will do in the 1200 hp range.
Both are too big to fit on a combine IMO.
