I don't know how your dealer does but mine doesn't do any type of cylinder rebuild. I had 2 that needed rebuilt on my dirt pan. Checked at the dealer and they said they would just send them off to be rebuilt and then charge me more for the job. I found my own shop and had both done for less than $200 with a 2 yr waranty. They even picked them up and brought them back to me at no extra charge.
