Setup and Installation
Follow these steps for proper installation of the Fleetguard LF691A oil filter. Always refer to your engine's service manual for specific procedures and torque values.
- Preparation: Ensure the engine is off and cool. Place a drain pan beneath the filter to collect old oil.
- Remove Old Filter: Use an appropriate filter wrench to loosen and remove the old oil filter. Be prepared for oil spillage.
- Clean Mounting Surface: Thoroughly clean the filter mounting base on the engine, ensuring no old gasket material remains.
- Lubricate Gasket: Apply a thin film of clean engine oil to the new filter's gasket. This ensures a proper seal and easy removal next time.
- Install New Filter: Screw the new Fleetguard LF691A filter onto the engine mounting base by hand until the gasket contacts the base.
- Tighten Filter: Once the gasket contacts the base, tighten the filter an additional 3/4 to 1 full turn (as indicated on the filter body, see Image 1). Do not overtighten, as this can damage the filter or mounting base.
- Refill Oil: Refill the engine with the recommended amount and type of engine oil.
- Check for Leaks: Start the engine and let it run for a few minutes. Check for any oil leaks around the new filter. If leaks are present, turn off the engine and re-check the filter's tightness.
- Verify Oil Level: Turn off the engine, wait a few minutes for the oil to settle, and then re-check the oil level. Add more oil if necessary.
