Maintenance FAQ & Troubleshooting

Q1: Why is the oil pressure low after installing a new LF670?
A: Check if the gasket from the old filter was left on the filter head (Double Gasket). If the filter is OEM standard, ensure the oil pump and relief valve are functioning. Our LF670 replacement is tested for correct flow resistance to prevent pressure drops.

Q2: How often should I replace the LF 670 on a Cummins NT855?
A: Typically every 250 to 500 hours depending on the environment. In high-dust mining or construction sites, we recommend shorter intervals to protect the crankshaft and bearings.

Q3: Why Choose This Lube Filter?
A: OEM-standard tri-metal structure and high-capacity media. It is trusted by repair shops and equipment fleets worldwide for its reliability in extreme temperatures.
