Congrats on your new combine! We have an 87 R-60 too. It has been a very good machine. For two seasons we have run it fully Hyperized. That has greatly improved its performance and I believe will extend its life due to not working machine very hard. We harvest only corn and soybeans so I dont have experience in other crops, but I strongly suggest Hyperizing if in those crops. Maybe check it out for other crops. A couple of things I suggest to look at on the engine. Check to see if centrifugal oil filter has been cleaned. I think the book says to clean every 1,000 hours. As long as you are in there look at cooling fan for excessive wear (the specs are in the book). They will start to run hot when the fan cant move enough air. Great engine, very fuel efficient. Good luck. Brian
