Babbitting is the method of removing and replacing worn bearing material on main bearings, connecting rod bearings, and (some) cam bearings on antique and vintage engines. The general era of engines that used babbitt bearing material range from the early 1900s to the middle 1930s with the exception being the Chevrolet 216cid and 235cid engines, which used babbitt for the connecting rod bearings as late as 1953.

Babbitted bearings are typically made with an outer shell of either steel or bronze that holds a layer of babbitt material on the inside. The babbitt material acts as the bearing surface which wears over time of operation. However, in some engine applications there are no actual bearing shells. In these applications the "main bearings" are poured directly into the block and main caps. After examination, our babbitt specialist melts out the old babbitt material and pours a new layer of babbitt and machines it to a new SEMI-FINISHED bearing. This semi-finish includes the machined oil grooves and/or oil pockets. The next step is to have a well equipped shop perform an ALIGN BORE to size the semi-finished bearings to accept the crankshaft.

Some connecting rods have an insert or shell to hold the babbitt material, other times, when there is no outer shell, the babbitt material is poured directly in the rod itself. With the connecting rods, our babbitt specialist can cut the material to size if supplied with the appropriate crank size.

Egge uses "4X" babbitt material, which is a nickel based aircraft quality babbitt material selected for its top quality and long life. All pricing for babbitt work is done on a case by case review and will depend on the length of time and work performed.

Reminder to all of our DIY's and shop mechanics: Please do not discard any worn parts from your project vintage or antique engine, as they may be crucial for proper identification of the correct replacement part or needed for remanufacturing.
