  • Replacing a damaged filter with the correct thread and size

Installation Notes and Tips

Verify the thread size, height, and outside diameter against the existing filter before installation. Confirm the engine or equipment calls for a 1 1/8-thread oil filter with the listed dimensions, and inspect the sealing surface so the integral gasket seats cleanly. For Caterpillar applications, match the replacement to the original part number and service specification.
