This photo shows all the bearings that have been poured. The bearing cap on the left has been filed and scraped to fit. The lube hole has been drilled. The bearing cap on the right has just been poured showing the very little babbitt seepage on one end. This bearing has not been touched since pouring. The lower right side of the bearing casting shows the asbestos shims that are used to prevent the molten metal to be poured in the cap from fusing with the lower half.
