Yes replace the coupler for sure, the shaft may be ok still. We have done 3 since we started using the N_R series, 2 times only the coupler on the cylinder needed to be replaced, this last time this year we missed it and the splines let go in the feild and ended up needeing new gearbox shaft as well. The new ones are not cheap but better now than a coupler and a shaft during harvest. Due to this and the ease of cylinder removal we began pulling rotor every year to check coupler and you do get a much better lok at rotor than watching while someone turns it over.
