From my sales literature... 4000 SOS ratio - 30.01:1 final drive. 3000 manual shift ratio - 6.67:1.
Don't think that swap will work. You could make another over-powered 3000 - use the 4000 engine in font of your 3000 tranny/rear.

From what I can see by looking at cutaway photos, the 6 speed and 8 speed look interchangeable, except the 4000 uses a continuous running pto drive that also operates the hydraulic pump. The SOS has a shifter for ground speed pto. From my checking of the 2000 industrial with planetary reduction, the straight through reduction is 16.67 to one. The planetaries are 4.5 to one, thus the ring and pinion check out at 6.67 to one. I also own a 3000 ag. All I can say is the industrial has maybe 50-60% of the speed of the Agricultural. (Not terribly slower.) I"d have to expect some variation in the ring and pinion. For example, 9 x 60 = 6.67. I don"t have my Gleason manual handy, but ratios from about 3 up to about 9 are not too wild. Just need to adjust the bearings so that the two gears mesh properly.
