im trying to figure out what the smaller driveshaft going from the transmission to the rear end of my dozer does? the shaft that spins whenever its running. it has a little play and has a noticeable wobble at idle but appears to run true with any rpm. the u joint feels ok and it feels like the yoke is loose to the transmission. the parts books I have really suck in my opinion for figuring anything out its a powershift 3f 1r
It's for the PTO shaft.
for a winch? will it function without it? seems silly to have it spinning for no reason
