We get very little bounce in buckets. I think you would be safe with about 2” from all the way in.
Drive shaft-+8" or whatever is needed
1/2' to 2" yoke to tailshaft depending on how long the yoke is.
No more than 2" offset from tailshaft to pinion.
so no thoughts about minimum length of the driveshaft it self?
A drive shaft that is only 10" long overall will only move in and out of the transmission 3/16" (actually .2") on a 2" vertical movement of the rear end. A 1" vertical movement would result in just under 1/16" lateral travel. The rear ends "usually" travel up and down less than 2" so I would say you are on the right track, your mileage may vary.I would think if you bottom out the yoke, pull it out an inch and use that dimension for the driveshaft length you should be ok. Although, you don’t want to bottom out the yoke on a bump either.
Anyone have thoughts?
