LF9009 LF9080 Cummins Lube Filter LF3345 LF3349 Generator Parts

Cummins engine filter elements are crucial for maintaining engine performance and longevity. They include the following components:

• Function: Blocks dust particles, ensuring smooth air intake for optimal engine performance in both low and high-temperature environments.
• Maintenance:
  • Only the external filter element can be purged; the safety filter element should not be purged.
  • Purging air pressure should be below 0.5 MPa.
  • Replace the safety filter element after three purging cycles.

• Function: Removes impurities from the oil, ensuring the engine operates smoothly.
• Features: High filtration accuracy, low flow resistance, and long service life.
• Replacement Steps:
  • Clean the area around the oil filter seat.
  • Discard the old filter element and O-ring seal after removal.
  • Install the new filter with clean oil and tighten according to the specified torque.

• Function: Ensures fuel purity and improves combustion efficiency.
• Replacement Steps:
  • Remove and discard the old filter element and O-ring in a clean area, away from flammable materials.
  • Avoid pre-injecting fuel into the new filter element.
  • Lubricate the new O-ring with clean oil before installation and tighten according to technical specifications.

• Function: Effectively separates oil and water in the fuel, protecting the engine from damage.
• Maintenance:
  • Discharge water and sediment from the fuel filter and oil-water separator daily.
  • Replace regularly according to the maintenance cycle for Cummins models.

• Function: Purifies the water quality in the cooling system and slowly releases granular DCA for added protection.
• Benefits: Prevents scale formation, ensuring the cooling system operates normally.
• Replacement: Should be replaced each time the antifreeze is maintained or changed.
