Hydraulic Filter 5I-8670 for Caterpillar Mini Excavators & Generator Sets
5I-8670 hydraulic filter for Caterpillar 307-345C excavators and generator sets. OEM cross-reference verified. Orders from IXIN Filter.
Description
This 5I-8670 hydraulic filter is an advanced-efficiency spin-on hydraulic filter engineered as a direct replacement for the Caterpillar 5I-8670, one of the most widely used hydraulic filters across CAT’s compact and mini excavator lineup. It’s designed to keep hydraulic system fluid clean and protect pumps, valves, and cylinders from wear caused by particulate contamination.
Product Overview
The 5I-8670 hydraulic filter uses pleated filter media rated for advanced-efficiency filtration, designed to capture fine particulate contamination and extend the service life of hydraulic system components. Built with a standard M45 x 2.0 spin-on thread to match OEM housing specifications, each unit is dimensionally verified against OEM measurements and tested for filtration performance before shipment — not just matched by part number.

Frequently Asked Questions
Is this a hydraulic filter or an oil filter? The 5I-8670 is classified by Caterpillar as an advanced-efficiency hydraulic filter. It’s sometimes listed under “oil filter” by aftermarket sellers because it uses a similar spin-on format, but its function is hydraulic system filtration, not engine lubrication.
What excavators use the 5I-8670 hydraulic filter? It’s used across CAT’s mini and compact excavator lineup (301.5 through 314D), including the widely used 307 and 308 series, as well as track feller bunchers and CAT 3508/3512/3512B generator sets.
Will this fit all the models listed? It fits the equipment listed above, but hydraulic system configurations can vary by production year and serial number range. We recommend confirming your machine’s specific configuration before ordering, especially for bulk purchases.
Do you offer samples before a bulk order? Yes. We recommend requesting a sample for independent testing before committing to a bulk order, especially for first-time buyers.
