Thanks for the info on your dozer. The crank can be replaced along with the cylinder sleeves you can find rebuild kits on ebay.com, brokentractor.com, reliableaftermarketparts.com or coneequip.com if you want to go that way.Alrman- The engine was allowed to fill with water and sit. After they drained it out and got it to turn over and start, it spun a bearing. Should have been torn down. Scored crank badly scored cylinders. damaged pistons. etc.
