Installation and Operation

Replacing crankshaft bearings is a procedure requiring precision. Before installation, ensure the crankshaft is properly cleaned and its diameter is measured for wear. We recommend using fresh engine oil or a pre-lubrication preparation during the first startup to prevent overheating of the new bearings. Regular oil pressure checks extend the life of this set.
