Combines 860 massey specs

i was told by a massey shop foreman awhile back that it was around 240-250... but i could be wrong

I was told 180 or 185, but I don't know if that was for the older (red) V-8's or the newer (black) motors. I think there were several different ratings even within the red and black motors. I would think that even if the late models were 180, it would be fairly easy to get 200+ out of them, since you have 540 c.i. to work with.

Horse power on MF Combines is as follows, all figures taken from Massey service manual. AT6.3544 = 140 hp @ 2400 rpm; AT6.3544cc = 158 hp(intercooled version); AV8.540 = 168hp @ 2400 rpm (prior to ser. n 15224); AV8.540 = 179 hp@ 2400 rpm (S.N. 15224 and up) The V-8 engine came with the hydro, which sucked about 30 hp. Any turned up 3544 was every bit as powerful as the V-8. The unions killed that company (M.F.) Why Massey stuck with those Perkins Diesels I'll never know. They were about the worst for fuel economy and durability. Massey had an excellent cylinder design (hi-enertia) much better than Deere even uses today. Those cylinders did a better job with less hp. Massey had a reputation for quality control problems, resulting in more maintenance. Several areas should have been built heavier. I still like those old Masseys, easily the best looking machine out there....still. But mine is 19 years old and I need something newer, so its time to move on, and it will be a Deere, they do build a good machine.

The early 760 was 180hp for the v8 540 and was increased in succeeding years. I would have to check my papers but I believe it went something like this. 180,183,190, 201hp. They sold a kit to power up older engines to 201hp. I increased mine on a 760 to about at least 201hp but the shop increased the fuel and setting even farther. The kit is no longer available but the parts are.
