Another specialty at Hart’s Machine Service is babbitt bearings. Most engines manufactured before the 1940’s had removable babbitt bearings which are no longer available today. Creating new babbitt bearings is the process of removing and refurbishing rod bearing shells, begins with cleaning the parts for the new babbitt bearings. Next, Hart’s Machine Service will take pictures of all parts to allow for duplication of all oil holes or characteristics unique to the original bearing shells on the finished product. Babbitt, a tin-based material begins as a bar and is melted down and then poured into a mold which connects the babbitt bearings to a steel or brass shell, or directly to the rod or an engine block creating new babbitt bearings. The new babbitt bearings are then machined to the correct specifications for the engine.
