Changing the oil in your 2021 Husqvarna TE150i is essential maintenance for optimal engine and clutch performance. This step-by-step MotoSport.com guide ensures your job gets done right, highlights any model-specific details, and lists all the tools you’ll need.

Tools and Supplies Needed

  • 10mm or 13mm socket (verify with your bike’s drain plug size)
  • Socket wrench or spanner
  • Oil drain pan
  • Oil funnel
  • Shop towels or rags
  • Replacement crush washers for drain bolts
  • Needle nose pliers (for cleaning oil screens or filter area if applicable)
  • Measuring cup (for filling proper oil amount)
  • Moto-specific transmission oil: 10W-40 (as recommended in the TE150i owner’s manual)
  • Torque wrench (if available, for precise reinstallation of bolts)
  • Gloves

Step-by-Step Oil Change Procedure

  1. Warm Up the Bike
    • Start your TE150i and let it idle for a few minutes. This warms up the oil, helping it drain fully and carry away more contaminants.
      Tip: Run the engine gently through all gears for best results.
  2. Stabilize and Prepare the Bike
    • Use a bike stand to keep the motorcycle level and stable.
    • Switch off the engine completely and allow a few minutes for hot components to cool.
    • Clean the area around the oil fill and drain bolts to keep debris out of the engine.
  3. Locate and Remove the Drain Bolts
    • The 2021 TE150i has two oil drain bolts, one of which is magnetic. Both must be removed for a complete drain.
      Note: The magnetic bolt attracts any metal shavings, so inspect it when removed.
      Model-specific call-out: Draining from both bolts ensures all oil and contaminants are removed from the transmission.
      Reference:
    • Place the oil pan underneath and slowly remove both drain bolts.
    • Allow the oil to drain completely. You may need to tip the bike slightly to get the last bit out. Reference:
  4. Inspect, Clean, and Replace Drain Bolts
    • Wipe the drain bolts clean. Check the magnet for metal shavings–minor residue is normal, but large flakes indicate excessive wear.
    • Replace the crush washers if worn or flattened.
    • Reinstall the drain bolts. If using a torque wrench, tighten to the manufacturer’s recommended specification.
  5. Clean Oil Level Check Screw
    • Locate the oil level check screw (above the starter, on the right side of the engine). Remove it to allow air release and ensure accurate filling.
      Model-specific call-out: The level check screw makes it easy to know when there’s enough oil in your 2021 TE150i; fill until oil flows slightly from this hole before re-installing it.
      Reference:
  6. Fill with New Oil
    • Remove the oil fill cap.
    • Using a funnel, add the recommended amount and type of oil (typically 10W-40 for the TE150i; check your cap or manual for capacity, usually about 700 ml–verify your specific model).
      Reference:
    • Fill slowly while checking the oil level check hole. Stop filling as soon as oil starts to gently seep from this hole.
    • Reinstall the check screw and fill cap securely.
  7. Final Inspection and Cleanup
    • Wipe the engine case clean. Dispose of used oil properly—your local dealer or auto parts store can recycle it.
    • Start the bike and let it idle for a minute, then turn off and inspect for leaks around fill and drain locations.
    • Tip: Recheck the oil level after your first ride; top off if necessary.

Key Model-Specific Details for the 2021 Husqvarna TE150i

  • This bike uses a transmission oil system—ensure you use proper motorcycle transmission oil, not standard engine oil.
  • Two drain bolts must be removed to fully drain the oil and contaminants.
  • The magnetic drain bolt helps trap metal filings before they cause wear—inspect carefully every oil change.
  • The oil level check screw ensures precise oil filling: add oil until a steady drip exits this screw’s opening when the bike is upright and level.
  • Use 10W-40 oil as recommended specifically for the 2021 TE150i.

Expert Tips for Your TE150i

  • Always change oil with the engine warm.
  • Replace crush washers every oil change to prevent leaks.
  • Avoid overfilling—the transmission is lubricated best at the correct level.
  • Check for oil leaks and unusual metal residue in your drained oil as early warning signs.
  • Change the oil more frequently if you ride in wet, muddy, or high-stress conditions.
