Brand New 360-3986 Connecting Rod Bearing Set for Caterpillar 312D2, 312E, 313D2

   Thank you for choosing SPARKLING MACHINERY.    

   The 360-3986 connecting rod bearing set is manufactured utilizing high-tier tri-metal construction (typically featuring a steel backing, a copper-lead load-carrying interlayer, and a micro-polished babbitt overlay matrix). Engineered to handle the immense cylinder firing pressures of Cat engines running under sustained load, these standard-size shell bearings efficiently distribute oil film thickness to avoid metal-on-metal friction. Replacing worn insert bearings during mid-life overhauls stops crankshaft knocking, protects the crank journals from catastrophic scoring, and holds oil clearances perfectly to factory specifications.
