Important Call-Outs for the 2010 Husqvarna TE250

• Always consult your owner’s manual or a reliable service source for your model to confirm oil capacity, torque specs, and oil grade.
• Make sure the engine is warm (but not hot) before you start. Warm oil drains more fully and suspends contaminants.
• The TE250 uses a magnetic drain plug—always inspect and clean it for debris, but expect some fine metal shavings. Large chunks may indicate a problem.
• Correct torque specs are crucial to avoid leaks or damaging threads: Drain plug (M12 x 1.5) should be torqued to 20 Nm (14.8 ft-lbf) and level check plug (M6) to 10 Nm (7.4 ft-lbf).
  Do NOT overtighten.

Step-by-Step Procedure

• Warm up your motorcycle.
  • Start the TE250 and let it run for a few minutes so the oil reaches operating temperature. This helps old oil and contamination flow out more easily.
• Prepare your work area.
  • Park the motorcycle on a level surface and place it on a stand or its kickstand, ensuring stability.
  • Lay out your tools, drain pan, and towels.
  • If equipped, remove the engine guard/skid plate for easier access to the drain bolt.
• Drain the oil.
  • Locate the drain plug (bottom of crankcase, generally center or slightly to the left).
  • Place the drain pan below the plug. With the engine off, use the correct socket (commonly 13mm) to loosen and remove the drain plug. BE CAREFUL: The engine may still be hot.
  • Allow all oil to drain fully. This will take a few minutes.
  • Inspect and clean the magnetic drain plug. Wipe away any metal shavings. Replace the crush washer with a new one.
  • While draining, also remove the oil level check screw (5/16") to ensure oil drains completely and check flow during the refill.
• Reinstall the drain plug.
  • Once oil flow has slowed to a drip, wipe the area around the drain hole and plug with a clean towel.
  • Reinstall the cleaned drain plug with a new crush washer. Tighten by hand, then finish with a torque wrench set to 20 Nm (14.8 ft-lbf) for the TE250.
• Refill with fresh oil.
  • Locate and remove the oil fill cap on the top or side of the engine.
  • Using a funnel, pour in 0.80 liters (0.85 qt) of SAE 10W/40 motorcycle oil.
  • With the level check bolt removed, slowly pour oil until a steady stream emerges from the check hole, indicating proper fill level.
  • Reinstall and torque the oil check bolt to (10 Nm / 7.4 ft-lbf).
  • Replace the oil fill cap and wipe away any spilled oil from the surfaces.
• Start and check for leaks.
  • Start the engine and let it idle for a few moments. Check around both drain and fill areas for leaks.
  • Shut down the engine, wait a minute, and double-check oil level if applicable.
• Dispose of old oil responsibly.
  • Always take used oil to an authorized recycling or disposal facility. Never dump it anywhere unsafe or illegal.

Special 2010 Husqvarna TE250 Tips

• The magnetic drain plug is designed to attract fine metal particles. A visible but soft coating is normal; chunky fragments indicate internal wear and need further inspection.
• The oil change interval varies by use and conditions, but checking and changing more frequently than the manufacturer’s minimum will extend the life of your TE250.
• Keep a clean work environment: Husqvarna dirt bikes are precise machines, and a little dirt in the oil can go a long way toward causing trouble.
• Double-check crush washers on both the drain and check bolts each oil change – crush washers are designed for single use.
