Changing the oil in your 2019 Husqvarna FC 450 is a fundamental maintenance task to preserve engine performance and longevity. This thorough guide—proprietary to MotoSport.com—covers all the specific steps, tools, and tips you need for a quality oil change.

Tools and Supplies Needed

  • Socket set (8mm, 13mm common)
  • Torque wrench (to manufacturer specs)
  • Drain pan (for used oil)
  • Shop towels or rags
  • New oil filter (OEM or reputable aftermarket)
  • Engine oil (see recommendations below)
  • Small pick tool (for O-ring removal)
  • Funnel
  • Replacement O-rings (included with most oil filter kits)
  • Latex gloves (optional, for cleanliness and protection)
  • Skid plate removal tools (if equipped)

Recommended Oil Specifications

  • Oil Type: High-quality synthetic 4-stroke motorcycle oil, typically 10W-50 (always verify with your manual)
  • Oil Quantity: 1200 mL for the 2019 FC 450, but always consult your manual and verify with the dipstick or sight window after filling

Pre-Oil Change Preparations

  • Start the motorcycle and let it idle for 3–5 minutes to warm up the oil. This helps the oil drain more thoroughly and removes suspended engine particles.
  • With the engine off, place your bike upright on a stand on a level surface.
  • If equipped, remove the skid plate using the appropriate tools.

Step–by–Step Oil Change Procedure

  1. Place your drain pan directly underneath the engine’s drain plug.
  2. Remove the oil fill cap on the engine case to allow oil to drain easier.
  3. Remove the drain plug (usually 13mm) located under the engine, and allow all old oil to drain into the pan.
    • The FC 450 has two oil screens: one short and one long, each with O-rings. These also need to be removed, cleaned, inspected, and reinstalled.
    • Be careful: engine and gear oil are hot after running the bike.
    • Inspect the drain plug for metal particles. If found, consult a technician, as this can indicate abnormal wear.
  4. Remove the oil filter cover with a socket (usually 8mm) and pull out the old oil filter.
    • Make sure the oil filter gasket comes out with the filter.
    • Lubricate the new filter with fresh oil and insert it into place.
  5. Clean and inspect all sealing surfaces. Replace any damaged O-rings or gaskets before reinstalling the drain plug, screens, and oil filter cover.
  6. Torque all bolts (drain plug, filter cover, and screens) to manufacturer specifications to avoid leaks or thread damage.
  7. Refill the engine with 1200mL (1.2L) of the recommended oil. Use a funnel and pour slowly to avoid spillage.
    • A sight window on the right side of the engine case shows the correct oil level (should be halfway up to three-quarters full).
  8. Reinstall the oil fill cap and wipe up any spills.
  9. Start the bike and idle for 3 minutes. This circulates oil through the engine and filter.
  10. Turn off the bike and allow it to settle for 2–3 minutes. Recheck the oil level in the sight window and add oil if necessary.
  11. Reinstall the skid plate (if removed) and clean all tools and work areas.

Husqvarna FC 450 2019 — Special Call–outs:

  • Oil Screens: The 2019 FC 450 engine uses two oil screens (short and long) in addition to the filter. These should always be cleaned thoroughly during each oil change to ensure debris doesn’t circulate in the engine.
  • Oil Volume: Always verify you’re using the right amount—1.2L is standard, but the sight glass is the final authority.
  • Frequent Changes: This high-performance dirt bike requires frequent oil changes. Husqvarna recommends every 6 hours of riding or after any extremely dusty/muddy rides.
  • Drain Plug Location: The FC 450's drain plug is centrally located on the bottom of the engine. Take care not to over-tighten.
  • Sight Glass: After running and resting the bike, oil should be between half and three-quarters in the glass window. Overfilling can cause foaming and damage—ensure accuracy.

Disposal and Environmental Tips

  • Place all drained oil in a sealed container and take to an authorized disposal or recycling center. Never dump oil into drains, onto the ground, or in trash bins.
  • Wipe up spills and recycle used filters if possible.
