Isetta - Engine Disassembly


As I mentioned in the transmission rebuild post, I've decided to use Bill Rogers for rebuilding the engine and transmission. Before the engine was sent to Bill, I had had the carburetor rebuilt by Bing, and had done some minor cosmetic things such as bead blasting and repairing cracks in the engine cooling shroud, bead blasting the the valve covers, fan, point cover, and cleaning up the blower housing. This is a picture of the engine as I was crating it to send to Bill. All of the photos below this were taken by Bill during his rebuild of my engine. I have a link to Bill's website in my sidebar links.
