Ah, a guy that knows the value of preventive maintenance and following OEM suggestions, lol. I always make a note of balancer age and hours on inspections. Sometimes it works, sometimes not. I have a feeling that the recommendation is at 4500 hours because Deere feels that's the absolute earliest they can start failing in the worst conditions, but they're probably actually good to go for several thousand more hours. As I said, some guys replace and some guys take the chance. It's not an especially fun job on an 8000/8010 of any vintage, thanks to that big, black intake tube, but a good 3 or 4 hours can usually have one swapped, along with a new front seal. When it comes to adjusting valves, it's worth checking, especially on later engines with those nice plastic gaskets with the rubber seals. Much nicer than scraping off cork. Most always, the valves will just be a few thousandths off an still within specs, as Deere gives quite a bit of leeway, but it's relatively cheap insurance. We SPG valve adjustment at around 3.5 hours on an 8000, but if the hood is already off for inspection and the technician can't do it in well under an hour, there's something wrong. My only real gripe about any of the 8000s is that I've never got any real amount of field-time in one. I've driven probably 200 or more of them here at the shop and on service calls, have done some post-repair testing and demos, but haven't ever spent hours on end in one, and I'd like to. I help my uncle and grandpa farm some on weekends when I can, and they don't have anything newer than the 4560 (which is still a nice ride) or bigger than their 7210 and 7410. At any rate, we simple don't work on 6081s to any degree, apart from simple stuff like nozzles, exhaust gaskets, an occasional front or rear seal, etc. I've overhauled on 6076 out of an 8200, and have had two 6081s off the front frames to replace pan gaskets, and that's the extent to which I've had to dig into 8000-series engines to any depth. But it sure will be nice when we start doing more overhauls and underhauls, and can hoist the motor off and stick it right on the rollover stand. As much as I like engine work, I don't enjoy the old drip on the head of doing a conventional overhaul or underhaul on the older tractors.
