Complete Guide: Caterpillar Filters for Excavators

Filters are the most critical component to protect the engine of your Caterpillar excavator. Correct maintenance can double the useful life of the equipment.

The oil filter must be changed every 250 operating hours under normal conditions. In dusty environments such as Andean mining, it is recommended to reduce the interval to 150 hours.

For the 320 series (320D, 320E, 320F, 320GC), the main part numbers are: Oil filter 1R-0749, Primary fuel filter 326-1644, Secondary fuel filter 235-9685.

Always verify compatibility using the engine and chassis serial number (SN). Contact your local Dax Parts office to confirm availability and delivery times.
