2064202 Rectifier Fits Caterpillar Models

One New Aftermarket Replacement Alternator Rectifier for Caterpillar (Cat) Engines and Equipment

This aftermarket replacement rectifier assembly (Part No. 2064202, also formatted as 206-4202) is a component of the alternator charging system used across a wide range of Caterpillar (Cat) engines, motor graders, generator sets, and industrial power units. The rectifier converts alternating current (AC) produced by the alternator into direct current (DC) to charge the battery and power the machine's electrical system. Replacing a worn or failed rectifier restores proper alternator output and prevents electrical system failures.
