I seen in our 1850 manual that a high speed gearset was avaible at one time. Placed fourth almost exactly between 3rd and 5th and really speeded up 6th. Was very many ever sold like this? Was the same thing ever availble for the 1600? When I rebuild the 1850 it is going to get the O/U out of our parts 1855. Was a O/U ever avaible for the 1600? I know by going from the hydraul shift to the O/U helps road speed quite a bit. The high speed gearset gets the top speed up to around 20 mph with the O/U, thats alot better than the 14.7 the manual says it will do as it sits. The reason I ask is I'm making enough of my own hay and some custom work that the drive times are killing me. If I could have shaved 5 or 10 minutes off my drive time today I could of had the last round and a half done before the rain got me and the hay soaked, suppose I could get a newer tractor with a higher road speed but I just like that 1600 way to much to give it up. Perfect size for running the round baler, just enough horsepower to get the maximum capacity out of the round baler without overpowering it and blowing shearpins all day. That and the most important reason is it was the last Oliver my grandfather bought before he passed away. As always any help is greatly appreciated. | ||

The over under units were not even available yet when the 50 series were introduced. So the answer to the 1600 is no. I can check later tomorrow if the high speed ring & pinons were available for the 1600. We sold one 1650 with the high speed rear end. He farmed little farms all over and purchased one to cut down his travel time. | ||

Ring and pinion huh? After looking at the manual it looked like in the 1850 4th/6th gear set was changed to a differant ratio. The rest of the gears were still listed as the same in the speed charts. | ||

A far easier approach would be to run larger rear tires. You can easily do the calculations ahead of time so you know which tire size will result in what top speed. | ||

You could always get a ring and pinion from an industrial. According to my parts book, the indurtrial ring gear was optional on the 1650 row crop. Should work the same for the other models. If memory serves, under drive was 17% slower, and over drive was 20% faster than direct. So you can figure out your new road speed of a 1600 by adding 20% to the road speed. Taller tires are also a good suggestion. 18.4 34's will get you a couple more MPH over 16.9 34's. | ||

I believe this tractor has 15.5 34's on it yet, when I replaced them was going to go with a 16.9 34 radial. But what I'm hearing is that there is no O/U out of another model that will work in the 1600? How about that high speed gearset for the 1850? Anybody have any experiance on that one? | ||

I don't know why you couldn't put an over/under from a 1650 or 1655 in the 1600. The over/under was designed to fit in the same physical space as the hydra-power. The worst you might have to do is use a clutch disc from a 1650 or 1655 to match up to the splines on the over/under. My 1850 parts book shows a 51 tooth ring gear for ag applications, and a 47 tooth for Industrial applications. All of the pinion shafts I can find in the book are 8 tooth. So an industrial ring gear would speed you up a bit. It also looks like there was two sets of gears for 4th and 6th. One would be faster than the other, obviously. But the parts book only tells how many teeth one each one, not which tractor they went in. I looked at the book for the 1600 as well, and the tranny gears were all different for the ag version compared to the utility and industrial versions. |
