Proper maintenance is crucial for the longevity and performance of your 2015 Husqvarna TE250. One of the most vital maintenance tasks is changing the gear oil at regular intervals. This comprehensive guide from MotoSport.com will walk you through each step, including the tools you need, model-specific tips, and expert insights to help make the process smooth—even if it’s your first oil change.

Tools and Materials Needed

  • Socket set (check your drain and fill plug sizes, typically 13mm or 17mm for Husqvarna TE250)
  • Ratchet or wrench
  • Drain pan
  • Funnel
  • New gear oil (consult your owner’s/service manual for the recommended type and capacity; typically 10W-40 or similar motorcycle gear oil)
  • New crush washer or sealing washer (recommended, but you may reuse the old one if it’s in perfect condition)
  • Cleaning cloths or shop towels
  • Contact cleaner (optional, for cleaning residual oil)
  • Measuring cup (for precise oil fill)
  • Gloves (optional, but keeps your hands clean and safe)

Step-by-Step Oil Change Instructions

  1. Warm the Engine
    Start the bike and let it idle for a few minutes. Warm oil drains more thoroughly and helps remove contaminants suspended in the oil.
    Tip: Don’t get the engine too hot; just warm enough to help the oil flow.
  2. Stabilize the Bike
    Place the bike on a stand or a level surface, with both wheels securely supported.
  3. Locate and Remove the Drain Plug
    Find the oil drain plug underneath the engine. Position your drain pan directly below the plug.
    Loosen and remove the drain plug using the appropriate socket or wrench.
    Allow oil to completely drain out. It may help to tip the bike gently towards you (–30 degrees) to ensure all oil is drained, as some oil can pool inside the case.
    Inspect the plug–many Husqvarna drain plugs have a built-in magnet. Clean any metal particles off the magnet before reinstalling.
  4. Inspect and Replace the Crush Washer
    Inspect the crush washer for wear or deformation. Replace with a new washer if needed to ensure a good seal and prevent leaks.
  5. Reinstall the Drain Plug
    Clean the sealing surface on the engine thoroughly before reinstallation.
    Thread the drain plug by hand to prevent cross-threading, then torque it to the manufacturer’s specification (check your owner’s manual; overtightening can strip the case).
  6. Add New Oil
    Locate the oil fill plug/cap on the right side of the engine.
    Remove the fill plug and insert a funnel.
    Pour in the manufacturer-recommended type and exact capacity of oil (consult your manual–commonly about 700–800 mL for the TE250). Use a measuring cup for accuracy.
    Do not overfill. Too much oil can cause increased pressure and may force oil past seals.
  7. Replace the Fill Cap
    With the correct amount of oil added, wipe away any spilled oil and reinstall/tighten the fill cap securely.
  8. Check for Leaks and Final Level
    Start the engine and let it idle for a minute. Shut it off and check underneath for leaks.
    If your bike has a sight glass or dipstick, check the oil level and top off if necessary.
  9. Dispose of Used Oil Properly
    Take used oil to a recycling center or auto parts store that accepts used engine oil.

Specific Call-Outs for the 2015 Husqvarna TE250

  • No separate oil filter: The 2015 TE250 is a two-stroke, so it only uses gear oil for the transmission; engine lubrication is handled by the premix in the fuel. You do not need to replace an oil filter during this change.
    The oil change process differs from four-stroke bikes, which require new oil filters at each change.
  • Gear Oil Only: Ensure you’re buying the correct gear oil grade (check your service manual for viscosity and volume recommendations).
  • Metal particles: It’s normal to see fine metal particles on the magnetic drain plug. Large shards or an excessive amount may indicate internal wear or issues and should prompt further inspection.
  • Drain plug torque: Over-tightening the aluminum threads can cause permanent damage. Always use the recommended torque (check your service manual, typically around 15 Nm – but verify for your specific year and model).
  • Complete draining: Tip the bike slightly towards the left side while draining as a small pool of oil can remain inside the crankcase if the bike is perfectly upright.
  • Interval: Husqvarna recommends changing the gear oil about every 10–15 hours of riding, or more often if riding in extreme conditions.

Conclusion

Changing the gear oil on your 2015 Husqvarna TE250 is straightforward and essential for maintaining optimal shifting and engine longevity. Follow these steps, use the correct tools and lubricants, and remember the unique considerations for your two-stroke dirt bike. For any specific torque values or oil grades, always consult your owner’s manual. Ride safe, and keep your TE250 running at its best.
