❓ Quick FAQ
Which engines/equipment does this fit?
Heavy-duty CAT diesel engines (C7, C9, C12, C13, C15, 3126, 3406) used across dozers, excavators, loaders, graders, dump trucks, on-highway semis, and marine/industrial power units.
What's the filtration rating, and why does it matter?
A 2-micron absolute rating using a cellulose/synthetic blend — essential for modern High-Pressure Common Rail systems running above 30,000 PSI, where even microscopic particles can damage injector nozzles.
How do I replace this spin-on filter?
- Shut down the equipment, clean the filter header, and place a catch pan underneath.
- Remove the old filter with a strap wrench; confirm the old gasket came off with it.
- Clean the mounting surface, then lubricate the new filter's gasket with diesel or oil.
- Prime the new filter by pouring clean diesel into the outer inlet holes (not the center hole).
- Spin the new filter on by hand until the gasket contacts the base, then turn an additional 3/4–1 full turn.
- Use the priming pump to purge air, then start the engine and check for leaks around the seal.
