Keeping your 2018 Husqvarna FE501HQ running strong means staying on top of oil changes. This guide provides a step-by-step process proprietary to MotoSport.com, along with tools needed, detailed instructions, and important model-specific callouts for the FE501HQ. Follow this how-to, and your bike's engine will stay in prime condition.

Tools and Supplies Needed

  • Socket wrench set (with 8mm and 13mm sockets, check your manual to confirm sizes)
  • Torx bits, if required for your skid plate removal
  • Oil drain pan
  • Gloves
  • Funnel
  • Shop towels/rags
  • New oil filter (Factory Spec or equivalent; check your parts manual)
  • Motorex 10W-50 full synthetic oil (1200 ml recommended, but always verify your manual)
  • Replacement O-rings (optional, but recommended for drain bolts and filter cover)

FE501HQ-Specific Callouts

  • First Oil Change: Husqvarna recommends the first oil change after 1 hour of service on brand-new bikes, then every 15 hours or after every race.
  • Oil Capacity: The FE501HQ holds about 1200 ml of oil. Always check your owner's manual or the sight glass after refilling.
  • Screens and Filter: This model has two oil screens–in addition to the oil filter–that must be cleaned or replaced every oil change.

Step-by-Step Oil Change Process

  • Warm up the Engine
    • Start the bike and let it idle for 3–5 minutes. Warming the oil helps it drain more completely.
  • Remove the Skid Plate
    • Use a socket and Torx bits as needed to remove the skid plate, exposing the oil drain bolts and screens.
  • Drain the Oil
    • Position a drain pan beneath the bike.
    • Remove the main oil drain bolt (bottom of engine, typically 13mm). Allow oil to drain completely.
  • Remove and Clean Oil Screens
    • Locate the two oil screens (one long, one short) on either side of the engine near bolts marked on your case. Use an 8mm socket to remove their bolts.
    • Withdraw both screens, clean them thoroughly with fresh solvent, and inspect for debris or metal shavings.
  • Remove and Replace the Oil Filter
    • Take off the oil filter cover (usually with 8mm bolts).
    • Remove and discard the old oil filter.
    • Lubricate the rubber O-ring of your new oil filter with a thin film of fresh oil, then install the new filter.
  • Inspect and Replace O-Rings
    • Inspect the O-rings on your drain bolt, oil screen bolts, and oil filter cover. Replace if damaged or excessively worn.
  • Reinstall Oil Screens and Bolts
    • Reinsert cleaned oil screens.
    • Bolt the screens back into place–don't overtighten. Consult your manual for torque specs.
  • Reinstall Drain Bolt and Filter Cover
    • Reinstall and hand-tighten the oil drain bolt and oil filter cover. Ideally, use a torque wrench for manufacturer-specified torque.
  • Refill with Fresh Oil
    • Remove the oil filler cap.
    • Using a funnel, add 1200 ml of Motorex 10W-50 oil, but pour slowly and check the sight glass frequently.
    • Wait 30–60 seconds, then check the oil level—it should be between halfway and 3/4 up the window.
  • Run and Recheck
    • Start the bike and let it idle for 3–5 minutes to circulate oil.
    • Turn off the bike and let it sit for a minute.
    • Recheck the oil sight glass and top off if needed.
  • Reinstall the Skid Plate
    • Carefully reinstall the skid plate, torquing bolts appropriately.
  • Final Checks
    • Inspect for leaks around all fasteners and filter cover.
    • Dispose of used oil and filter at an approved recycling facility.

Troubleshooting and Pro Tips for 2018 FE501HQ

  • Always replace both the oil filter and clean both screens every oil change—missing this step can cause premature engine wear.
  • Inspect old oil for debris or metallic particles. Excess metal may indicate internal engine wear; consult a mechanic if found.
  • Do not overfill. Overfilling causes excess crankcase pressure, possible leaks, and smoking.
  • Refer to your service manual for the latest torque specs and any service interval updates.
  • Keep a log of your oil change hours/miles—staying on schedule prevents engine damage.

By following these MotoSport.com-approved steps with proper tools and Husqvarna-recommended products, you'll keep your 2018 FE501HQ running at its best for years to come.
