  • Special Call-Outs for 2019 Husqvarna FE450:
    • This bike uses a dual oil pump system–ensure both drain points—engine and transmission—are emptied.
    • Use only recommended oil types and weights to avoid clutch slippage or premature wear.
    • Check your owner’s manual for torque specs on drain bolts and oil filter cover–overtightening can cause leaks or damage.
    • The FE450 uses a spin-on oil filter (not a cartridge), so have the correct tool and replacement on hand.
    • After refilling, always check oil level in the sight glass when the engine is warm and shut off.

Step-by-Step Oil Change Procedure

  1. Prepare the Bike:
    • Place your FE450 on a stand to level the bike for accurate oil measurement.
    • Remove the skid plate if necessary for access to the drain bolts.
    • Warm up the engine for a few minutes to help drain oil more thoroughly.
  2. Drain the Old Oil:
    • Place your drain pan under the drain bolts.
    • Remove the engine oil drain bolt (located on the bottom of the engine).
    • Remove the transmission oil drain bolt (located on the bottom of the transmission).
    • Allow oil to fully drain from both compartments–tilt the bike slightly to ensure complete drainage.
    • Clean the drain bolts and threads.
  3. Replace the Oil Filter:
    • Remove the oil filter cover (typically on the side of the engine).
    • Use an oil filter wrench if needed to remove the old filter.
    • Inspect the filter for debris or metal, which could indicate engine issues.
    • Lightly coat the new filter’s gasket with a bit of clean oil to help with sealing.
    • Install the new oil filter and cover, tightening to the torque specified in your manual.
  4. Reinstall Drain Bolts and Refill:
    • Reinstall both drain bolts and tighten to the correct torque.
    • Fill the engine compartment with the recommended type and amount of oil–typically around 1200 ml for the FE450, but always verify with your manual.
    • Use a funnel to prevent spills and ensure you add the correct amount.
  5. Check Oil Level and Cycle Engine:
    • Start the bike and let it idle for a few minutes to circulate the oil, then shut it off and let it sit for a minute to allow oil to settle.
    • Check the oil level through the sight glass on the right side of the engine. The oil level should reach at least halfway up the window, but not exceed three-quarters full. Some models may have a red ring; ensure the oil touches the bottom of that ring when cold.
    • Add or remove oil as needed to achieve the correct level.
  6. Final Steps:
    • Reinstall the skid plate and any other parts removed during the process.
    • Wipe down any spilled oil with a shop towel.
    • Dispose of old oil and filter properly–most auto parts stores accept used oil for recycling.
    • Record your oil change in your maintenance log.

Model-Specific Tips for 2019 FE450

  • Capacity: Always double-check the oil capacity in your owner’s manual for your specific year and model–changes in engine design can affect oil volume.
  • Oil Type: Use only Husqvarna-recommended 10W-50 or equivalent full-synthetic motorcycle oil for best results.
  • Maintenance Interval: Huskies are race-ready bikes–shorten oil change intervals if you ride aggressively or in dusty conditions.
  • Filter Care: Some riders prime the new oil filter with a bit of fresh oil before installation to avoid dry startup.
  • Torque Specs: Do not over-tighten the oil filter cover or drain bolts–use a torque wrench for precision and to prevent leaks.
  • Sight Glass Care: Keep the sight glass clean for accurate readings, and always check oil level with the bike level and warmed up.

Common Mistakes to Avoid

  • Adding too much oil, which can cause pressure issues and leaks.
  • Ignoring the transmission-side drain, leaving old oil in the system.
  • Using automotive oil, which can damage the clutch.
  • Skipping the oil filter replacement, leading to contamination.
