Engine and driveline component longevity would be a longer term issue. I could see it cracking pistons within 1000 hours. A lot would depend of course on how hard it's used. [Reply]   [No Email]

Is pretty much the same on a 66 and 76. I would dare say if he set it on a dyno for 85 or so... It should be fine. My 77 is running around 105 for the past 3000 hours and is at 8000 total hours, original other than two head gaskets... I know of one that's probably close to 120... And he's broken some rings. I know the compression ratio is a bit lower on the turbo pistons but shouldn't be a big factor if he doesn't go too far.... I know... Famous last words. Rod [Reply]  [No Email]

I've seen factory stock 7610s crack pistons, not turned up, just worked hard all its life. Clutch is lighter on the 6610 (12" vs 13"), and the finals are as well (2 speed vs single speed PTO). On the older 7000s and 7600s, the transmission gears and bearings were different as well. If it was set to 85, I would agree, it would likely be fine, cooling aside. [Reply]  [No Email]

I know for certain that all had the same 13"clutch after 10/85 or some date around there. I know you're corect that the older series tractors did use heavier components on the 7xxxx tho. As far as cracked pistons.... I'd have to wonder if some of that isn't due to a bit too much ether... Rod [Reply]  [No Email]
