You will have to unbolt the ring gear from SG before you send it to RRR. There are no bearings and seals inside the SG. Remember the ring gear bolts are left hand thread.
Ok. I was hoping to send the SG to you, and have a local shop put the new gears, bearings and seals in, while you have the SG. Will the shop be able to setup the gears, etc without the SG unit?
