rebuilding Oberdorfer Pump

I am going to rebuild the Oberdorfer 202M-15 pump on my M25XP Universal. The pump kit comes with a carbon bushing that shattered when I removed the old one. Does anyone have experiance rebuilding this pump? I assume if I try and press it it will shatter, and I assume that I may need to Heat the pump body in the oven and freeze the bushing.

Anyone have experiance with this pump, or thoughts on it?

And this year, upon starting the engine for the first time, I noticed the pump is leaking AGAIN!. This is the pump that I installed in 2012 @ 578 hrs. It appears that the graphite bushing around the shaft had worn in the past ten years, and 1000 hours. Fortunately, I had a backup pump. Sharing this because I believe that the Oberdorfer Raw Water Pump is a consumable item. Good for ~1K hours.
