Tools & Supplies Needed

  • Box end wrenches or socket set (specifically for drain and filter covers)
  • Oil drain pan
  • New oil filter (OEM part number: 77038005044 or equivalent)
  • Replacement O-rings (especially for filter cover O-ring 0770039026)
  • Crush washer for drain bolt
  • Measuring cup (to add oil to spec)
  • Clean rags or shop towels
  • Funnel
  • Recommended engine oil (consult owner's manual; usually high-quality 4T full synthetic, approx. 1200ml)
  • Torque wrench for reinstalling bolts to spec
  • M6 bolt (for removing stuck oil filter cover if needed)
  • Gloves (to protect hands from hot oil)

Step-by-Step Oil Change Process

  • Warm Up the Engine
    • Run the engine for several minutes to bring oil to operating temperature. This helps suspend contaminants and drains oil thoroughly.
    • Shut off the bike and let it cool slightly; oil will be hot.
  • Remove Skid Plate (if equipped)
    • If your FE450 has a skid plate, remove it to access drain and filter areas.
  • Drain the Engine Oil
    • Position your drain pan beneath the engine.
    • Remove the drain bolt with appropriate wrench. Be cautious: hot oil will flow quickly.
    • Let oil drain completely for several minutes.
    • Inspect the crush washer on the drain bolt; replace if needed to prevent leaks.
  • Clean Oil Screens (If Applicable)
    • The FE450 uses two oil screens (consult manual for locations).
    • Remove both screens and clean thoroughly with solvent or contact cleaner. Reinstall securely when clean.
  • Replace the Oil Filter
    • Remove both bolts from the oil filter cover. If the cover is stuck, use an M6 bolt in the center hole to gently back it off. Only tighten the bolt by hand, otherwise you can damage the cover .
    • Remove and discard the old filter and cover O-ring.
    • Lightly oil the new filter and install it.
    • Replace O-ring on filter cover with new part (OEM 0770039026) if it's worn or damaged.
    • Reinstall the filter cover, tightening bolts evenly to avoid warping.
  • Reinstall Drain Bolt
    • Install drain bolt with fresh crush washer and torque to spec (consult manual or use common torque for M12 aluminum drain bolts: 15-20 Nm).
  • Add New Oil
    • Remove the oil fill cap and insert a funnel.
    • Pour in 1200 milliliters of high-quality 4-stroke motorcycle engine oil (always check manual for the latest capacity, but 1200ml is standard for this bike) .
    • Reinstall fill cap.
  • Check Oil Level
    • Start the engine and let it idle for 3 minutes. Shut it off and allow oil to settle for another 2-3 minutes.
    • Check oil level using the sight glass on the clutch cover. For the 2011 FE450, oil should be between half and three-quarters full in the sight window while the bike is upright .
    • If low, add oil in 50ml increments and recheck.
  • Inspect for Leaks & Reinstall Skid Plate
    • Look around the drain bolt and filter cover for leaks.
    • Clean any excess oil off the engine with a rag.
    • Reinstall the skid plate, if removed.

Model-Specific Call-Outs for 2011 Husaberg FE450

  • Oil Filter Location: The 2011 FE450’s oil filter is mounted on the right-hand side behind a cover secured by two bolts. If cover is stuck, use a hand-tight M6 bolt only to avoid stripping .
  • Oil Capacity: Standard refill is approximately 1200ml; always double-check your sight glass after cycling the engine .
  • Oil Screens: Two oil screens must be cleaned and checked every oil change for debris, as they provide early signs of internal wear or failure .
  • O-Rings & Seals: The O-ring on the oil filter cover (39.34 x 2.62 mm NBR 70 SH, part 0770039026) can flatten over time and may cause leaks. Always inspect and replace if needed .
  • Tightening: Avoid over-tightening drain and cover bolts as the cases are relatively soft aluminum. Use a torque wrench whenever possible.
  • Oil Level Glass: The sight glass is prone to getting dirty from oil sludge buildup; if level is difficult to assess, clean the glass with solvent during this service .

Pro Tips from MotoSport.com

  • Routine Oil Change Interval: Change oil at least every 15 engine hours, or sooner for hard riding or racing .
  • Filter Priming: You can dip the new oil filter in fresh oil before installation to ensure instant lubrication on startup .
  • Proper Disposal: Take used oil and filters to a recycling center; never pour oil onto the ground or down a drain.
