Changing the oil in your 2021 Husqvarna FE501HQ is an essential maintenance task that keeps your engine running smoothly and extends its lifespan. This guide is proprietary to MotoSport.com and offers a detailed, model-specific walkthrough. Follow these steps to ensure your FE501HQ continues to perform at its best.

Tools and Supplies Needed

  • Metric socket set (8mm, 13mm, or specific to drain bolts and filter cover)
  • Drain pan
  • Oil filter replacement kit (including O-rings/gaskets)
  • Funnel
  • Contact cleaner or brake cleaner
  • Rags or shop towels
  • Torque wrench (for precise reinstall of bolts, set to 7 ft-lbs for oil filter cover)
  • Motorex SAE 10W-50 4T oil (or manufacturer-recommended equivalent, 1.3 liters required)
  • Gloves and safety glasses

Step-by-Step Oil Change Instructions

  • Warm Up the Engine
    • Start your FE501HQ and let it idle for several minutes so the oil thins out. Warm oil drains more completely and carries debris out with it.
  • Remove the Skid Plate (if equipped)
    • Use the appropriate socket or allen wrench to remove the skid plate for easier access to drain plugs and oil filter.
  • Place Your Drain Pan
    • Position your drain pan directly under the main drain bolt.
  • Clean the Drain Area
    • Use contact cleaner around the drain bolts and oil filter area to prevent debris from entering the engine.
  • Remove Drain Bolts – Drain the Oil
    • Carefully unscrew the main oil drain bolt under the engine. Allow the oil to drain completely.
    • There are additional smaller drain bolts with screens–remove these to get as much old oil and metal particles out as possible. Inspect the screens for debris.
  • Inspect – Clean Components
    • Inspect the condition of the drain bolt washers and replace them if needed. Wipe and clean all mating surfaces before reinstalling any bolts.
  • Reinstall Drain Bolts
    • Screw all cleaned and inspected drain bolts back in by hand, then torque according to your service manual‘s specifications (consult your manual for exact figures, but typical values are 10-15 Nm for drain bolts).
  • Remove and Replace the Oil Filter
    • The oil filter is housed behind a round cover usually secured by three bolts. Remove these and take off the cover.
    • Replace the oil filter with a new one, making sure to lubricate the new O-ring with a little fresh oil. Gently pre-fill the oil filter cavity about one third full before installation–this primes the filter and helps prevent startup wear.
    • Hand-thread the oil filter cover bolts, then torque them evenly to 7 ft-lbs for the 2021 model.
  • Fill with New Oil
    • Using your funnel, pour 1.3 liters of 10W-50 motorcycle oil into the oil fill port.
  • Check the Oil Level
    • Level the bike and verify the oil level is correct using the inspection window or dipstick. Add oil as needed, being careful not to overfill.
  • Start the Engine – Re-check Oil Level
    • Start the bike and run it for about 30 seconds. Let the engine sit for a minute, then check the oil level again and top up if necessary.
  • Reinstall the Skid Plate – Clean Up
    • Secure the skid plate and dispose of your used oil and filter at a local recycle center.
