Air filters are one of the most frequently replaced parts on heavy equipment. But there’s a way to make sure you're getting every hour possible from your engine air filter before replacing it.
Remember to check your Operation and Maintenance Manual (OMM) for proper safety procedures, and always wear appropriate personal protective equipment (PPE).
Watch this video to see how remaining useful life (RUL) technology works, and then keep reading below.
First, move your machine to a dry, level surface. Lower implements to the ground, lock out the hydraulics and turn off the engine.
Some Cat® dozers come equipped with a fully integrated, maintenance-free remaining useful life (RUL) sensor for your engine air filter. Instead of you waiting for obvious signs that something's wrong, the system will notify you that the Cat air filter needs replacement. You can prevent premature replacements and keep your equipment in better condition, while lowering total cost of ownership.
When a new filter is installed, the RUL percentage resets to 100%. As the filter captures contaminants during operating hours, the percentage begins to drop.
At 30% remaining useful life, you’ll see a “service soon” message. This is your reminder to order a new filter through your Cat dealer or Parts.Cat.com.
At 10% remaining useful life, the “service required” alert will appear, signaling it’s time to replace the filter.
Filter maintenance tip: Engine filter maintenance doesn’t involve taking out the filters. Instead, squeeze the debris evacuation port and clean the precleaner. Never clean the primary or secondary filters because damage of any sort or size can be a risk to your engine.
Filter replacement tip: Before installing a new filter, wipe down the exterior and interior of the filter assembly to remove dust or debris.
