How difficult is it to convert an 850 to an 860 assuming you have access to the components

Lots of parts would have to be sourced and changed. Not really practical that way. The best way is to swap out the entire transmission, flywheel and clutch from a donor tractor tractor.

Have to have flyweel,clutch , trans and depending on s/n will have to have r/a. I just did one for my self. Changed 4 speed to 5 speed/live pto. Had different s/n break. Had to change ring/pinion gear. Had different axle spline count so had to change axle gears in diff.

Double split. Then all parts from spacer plate between block and transmission back to center housing. Hopefully rear axle pinion shaft will have same splines as transmission output, or you'll need to cut the couplers in two and weld up one out of one half of each of the two.

If do have weld coupler it will have to be perfect because its only 3 inch long not 6+ like 4 speed.
