Anybody have some good tricks to know when re-installing the specialty rotor in a 1660 combine? The rotor has rice spikes at the rear, so it is not going to slide too good. Do you prefer to leave the spikes out, slide rotor in, then install rice bars? Or what is your preferred method? I am used to the standard rotor where I just took my tractor loader and shoved the rotor back up in the hole.
