I recently purchased a Case 210B-H with a model 21 backhoe-loader. The previous owner said it had some engine issues that needed to be addressed soon. Well he was right. I got it off the trailer, took it into my shop, tore it down and found spun bearings. The real challenge began when I started to look for rebuild kits for the G126 engine and found very little on the market, and what is out there is very expensive ($1,745 for an out of frame kit). I've purchased the service manual and the parts manual. The tractor also came with a 300 series parts manual. When I compare the G126 engine components from the 200 series tractors to the G148 from the 300 series tractors I find they have almost all parts in common. The key difference I'm seeing is the bore (3.125 for the G126 and 3.375 for the G148). I'd like to know if I can just bore out my 126 to a 148 and purchase the more-readily-available and much cheaper (about $650) G148 rebuild kit. Does anybody know of a reason why that wouldn't work, or does anybody have a better solution? If I could just replace the whole engine, I think I've read that a 148 would be a direct bolt in (if I could find one). But my concern there is the cost for an engine plus shipment, then have an old engine that might also need a rebuild. Thoughts???
