Q: What happens if I use a clogged LF3349 filter on a 6BT engine?
A: A clogged oil filter triggers the bypass valve, allowing unfiltered oil to circulate. This introduces contaminants to the crankshaft and bearings, leading to accelerated wear and potential engine seizure. We recommend replacing filters every 250-500 hours depending on the workload.
Q: Why choose this Lube Filter?
A: Our products feature an OEM-standard tri-metal structure and high-efficiency media, trusted by repair shops and equipment fleets globally for reliable filtration and durability.
