Tools and Materials Needed

  • Drain pan
  • 8mm socket or T30 Torx bit (for skid plate removal)
  • 13mm socket or wrench (for drain plug)
  • Socket wrench
  • Replacement oil filter
  • New engine oil (Always use manufacturer-recommended oil)
  • Replacement copper crush washer (for drain plug)
  • Replacement O-rings (for oil filter cap and oil screen, as needed)
  • Pin wrench or needle nose pliers (to remove and install oil screen)
  • Shop towels or rags
  • Safety gloves
  • Spray cleaner (for cleaning parts and sealing surfaces)
  • Torque wrench (14.8 ft-lbs for drain plug)

Step-by-Step Oil Change Process

  1. Prepare Your Workspace
    • Place the bike on a stable hoist, center stand, or have someone steady the bike if using the sidestand. Stability is key to safety and clean work.
  2. Remove the Skid Plate
    • Use an 8mm socket or T30 Torx bit to remove the two bolts securing the skid (bash) plate.
    • The stock skid plate is easy to remove, but some custom plates just need to be swung down for access. Removing it completely for cleaning is recommended.
  3. Drain the Engine Oil
    • Place a drain pan under the engine.
    • Identify the 13mm hex head drain plug at the rear of the engine; this plug has a copper washer. Do not remove any of the Allen-head bolts on the bottom of the engine, as these are not oil drain plugs and removing them can spell disaster for your engine.
    • Remove the drain plug and allow oil to drain completely.
  4. Remove the Oil Filter and Oil Screen
    • Locate the oil filter cover and remove it.
    • Take out the old oil filter. Always replace the filter during an oil change—this keeps the oil clean and the bike running strong.
    • The FE350S has an oil screen that also needs inspection and cleaning. Use a pin wrench or needle nose pliers to remove it.
    • Spray off the oil screen to remove debris and check for metal shavings.
    • Replace O-rings on the oil filter cap and the oil screen if they are damaged or flattened.
  5. Clean and Inspect Components
    • Wipe down the drain plug and all sealing surfaces with a clean towel.
    • Ensure the copper washer is replaced with a new one. Never re-use a crush washer–they are cheap and prevent leaks.
    • Lightly lubricate all replacement O-rings with fresh engine oil before fitting them.
  6. Reinstall the Oil Screen and Drain Plug
    • Push the cleaned oil screen completely back into the engine case.
    • Install the drain plug with the new copper washer and torque it to 14.8 ft-lbs–do not over-tighten.
  7. Install the New Oil Filter
    • Fit the new filter, ensuring it is installed in the correct direction. Grease the O-rings before installation.
    • Reattach the oil filter cover and torque to spec as per the owner's manual.
  8. Add Fresh Engine Oil
    • Fill the engine with the recommended type and amount of oil, per the owner's manual.
    • Check oil level using the sight glass. Top up if necessary.
  9. Final Checks
    • Start the engine and let it idle for a minute.
    • Shut off, wait 1–2 minutes, then check for oil leaks and re-check oil level. Adjust if needed.
    • Reinstall (and clean) the skid plate.

Model-Specific Tips for the 2022 Husqvarna FE350S

  • Magnetic Sump Plug: This collects metal particles; wipe it clean every time you change the oil.
  • Oil Screen Location: The oil screen isn’t always visible, be careful when removing and installing it—improper fitment can allow debris through to your oil pump gears and cause significant engine damage.
  • Do Not Remove Allen Plugs: Only use the 13mm hex head plug for draining oil. Removing other plugs can damage internal engine parts and is a common mistake with these models.
  • Check O-Rings and Washers: Faulty or reused sealing washers and O-rings are the top cause of oil leaks post-change.

Helpful Practice and Safety Reminders

  • Always consult your owner’s manual for torque specs and oil capacity.
  • Dispose of used oil and filters responsibly at your local recycling center.
  • Double check all bolts, covers, and the skid plate for proper reinstallation before riding.

Changing your oil on the 2022 Husqvarna FE350S is straightforward if you follow these steps and observe model-specific cautions. Regular maintenance prevents engine wear, improves shifting, and ensures years of fast, reliable dirt biking.
