Changing the oil in your 2015 Husqvarna FE350 is an essential maintenance task to ensure the longevity and performance of your dirt bike. This comprehensive guide from MotoSport.com will walk you through the process step-by-step, highlighting tools needed, specific features of the FE350, and best practices to avoid common mistakes.

Tools and Materials Needed

  • 13mm hex socket or wrench (for sump plug)
  • 8mm Allen socket or Torx T30 bit (for skid plate and oil filter cover screws)
  • Oil drain pan
  • New engine oil (consult owner’s manual for correct type and quantity)
  • New oil filter and oil screen (recommended to replace each oil change)
  • Copper crush washer for drain plug replacement
  • Grease or assembly lube (for O-rings)
  • Cleaning rags
  • Funnel and measuring cup (for proper oil refilling)
  • Bike stand or hoist for safe access

Key Model-Specific Information for 2015 Husqvarna FE350

  • The FE350 features a magnetic sump plug that collects metal particles—do not confuse other Allen-head plugs around the engine as sump plugs; only remove the 13mm hex plug at the rear.
  • There is an oil screen and a replaceable oil filter, both of which should be serviced during the oil change.
  • Removing the oil pump cover in search of the filter is a common mistake; the filter is accessed via a separate cover usually behind the skid plate.
  • Many skid plates cover the sump plug but often get coated with oil; it’s best to remove the skid plate entirely for a cleaner and more thorough job.

Step-by-Step Oil Change Procedure

1. Prepare Your Work Area and Bike

  • Place your FE350 on a stable bike stand or hoist to provide easy access to the bottom of the engine and skid plate area.
  • Ensure the bike is secure; having a helper hold it steady can prevent accidents when loosening bolts.

2. Remove the Skid Plate

  • Use the 8mm Allen socket or Torx T30 bit to remove the bolts securing the skid plate or bash plate.
  • Take off the skid plate completely to prevent oil from accumulating inside it and to expose the sump plug and oil filter cover clearly.
  • Clean the skid plate and bolts to remove any oil residues.

3. Drain the Oil

  • Place your oil drain pan directly under the magnetic sump plug, located at the rear bottom of the engine.
  • Use the 13mm socket to slowly loosen and remove the sump plug. Expect oil to start draining immediately.
  • Allow the oil to drain fully. The magnetic plug will collect metallic debris; clean it thoroughly before reinstalling.
  • Replace the copper crush washer on the sump plug to ensure a proper seal.

4. Remove and Replace the Oil Filter and Screen

  • Locate the oil filter access cover (usually behind the skid plate area).
  • Remove the screws holding the filter cover using an 8mm Allen or Torx bit as needed.
  • Carefully remove the old oil filter and oil screen from their housings.
  • Clean the filter housing area with a rag and contact cleaner if available.
  • Install new oil screen and a replacement oil filter per manufacturer instructions.
  • Apply a small amount of grease or oil to the O-rings before reinstalling covers and bolts to prevent leaks.

5. Reinstall Drain Plug and Covers

  • Reinstall the sump plug with new crush washer and torque to the specification in the owner’s manual (typically moderate torque to avoid stripping).
  • Reattach the filter cover and secure it with the appropriate bolts.
  • Reinstall the skid plate and tighten bolts securely.

6. Refill with Fresh Oil

  • Using a funnel, pour the recommended quantity and type of new oil into the oil fill port.
  • Commonly used oils for the FE350 are high-quality 4-stroke motocross oils specified in the owner's manual.
  • Allow oil to settle, then check the level using the dipstick or level window as per the manual’s instructions.

7. Final Checks

  • Start the engine and let it run briefly to circulate the new oil.
  • Inspect around the drain plug, oil filter cover, and skid plate for any signs of leaks.
  • Turn off the engine and recheck the oil level, topping off if necessary.
  • Dispose of old oil and filter responsibly at a recycling center.

Additional Tips for the 2015 Husqvarna FE350

  • Change engine oil approximately every 15 hours of riding or more frequently in harsh conditions.
  • Use genuine or high-quality aftermarket oil filters to maintain engine protection.
  • Handle the magnetic sump plug carefully, as it attracts metal particles that provide clues about engine wear.
  • Avoid removing other Allen-head plugs on the engine as they are not sump plugs and could cause engine damage if disturbed.
  • Keeping the skid plate clean and dry helps prevent corrosion and makes future oil changes easier.

Performing an oil change on your 2015 Husqvarna FE350 correctly will keep your engine running smoothly and maximize your bike's lifespan. Regular maintenance like this also supports better performance on the trail or track, ensuring your bike is always ready to ride.
