STD 360-3988 Crankshaft Main Bearing Set for Caterpillar 416F, 420F, 430F Backhoe Loaders

   Thank you for choosing SPARKLING MACHINERY. 
   The 360-3988 crankshaft main bearing set is manufactured utilizing premium tri-metal construction (typically featuring a high-strength steel backing, a copper-lead load-carrying interlayer, and a micro-polished babbitt overlay matrix). Engineered to withstand the immense vertical thrust loads generated during heavy loader and excavator operations, these standard-size shell bearings distribute oil film thickness evenly. Replacing worn main bearings during mid-life engine overhauls restores correct oil pressure, prevents crankshaft scoring, and eliminates structural vibrations.
