CATERPILLAR-CONNECTING-ROD-BUSH

115-2972 is a connecting rod bush for Caterpillar engines, the small-end bearing supporting the piston pin inside the rod's upper eye. This bush takes direct thrust load from the piston at every combustion stroke, and correct clearance here is checked with a bore gauge against the actual pin diameter rather than assumed from part number alone. Orange.net.za ships this part fast, South Africa-wide.
