Changing the oil in your 2019 Husqvarna TE250i is a crucial maintenance task to keep your dirt bike running smoothly and to extend engine life. This step-by-step blog, proprietary to MotoSport.com, covers all tools required, detailed steps, special model-specific notes, and pro tips to ensure you complete the job efficiently and correctly every time.

Tools and Materials Needed

  • Socket wrench (with suitable extensions)
  • 8mm and 13mm sockets (verify by inspecting your bike, but typical sizes for drain and guard bolts)
  • Drain pan
  • Funnel (narrow-neck recommended for small case openings)
  • Replacement gear oil – Husqvarna recommends 10W–50 or follow owner's manual specification
  • Torque wrench (to ensure correct torque on the drain bolt)
  • Cleaning rags
  • Contact cleaner or brake cleaner
  • Replacement crush washer (recommended with each oil change)

Preparation Steps

  • Warm up the engine for 3–5 minutes. This helps the oil flow out more easily when draining.
  • Turn off the bike and place it on a stable stand on a level surface for safety.
  • Gather all tools and position your drain pan under the bike, aligned with the gear oil drain bolt.

Step-By-Step Oil Change Procedure

  1. Remove the Skid Plate or Guard (if equipped):
    Using the 8mm socket, remove the two screws underneath the guard or skid plate. Allow the guard to swing down or fully detach to access the drain bolt easily. This step is essential, as access to the oil drain bolt on the 2019 TE250i is obstructed by the guard.
    Model-specific call-out: The guard can be cumbersome, and skipping this step could lead to a mess or stripped bolts. Always remove it for direct access.

  2. Locate and Remove the Drain Plug:
    Using the correct socket (typically 13mm), remove the oil drain bolt from the bottom of the engine case. Be cautious, as hot oil may spurt out when the bolt is removed.
    Let the oil drain completely into the pan. Remove the old crush washer from the drain bolt, inspect for wear, and replace if necessary.

  3. Clean the Drain Plug and Sealing Surface:
    Thoroughly clean the drain plug, especially if it has a magnetic tip. Remove any metal shavings or debris. Clean the area around the oil drain opening on the crankcase.

  4. Reinstall the Drain Plug:
    Attach the new crush washer to the drain bolt and carefully thread it back into the crankcase by hand. Tighten to the manufacturer's torque specification (usually around 15 Nm, but always check your owner's manual). Overtightening may strip threads and undertightening risks leaks.

  5. Refill with Fresh Oil:
    Remove the oil filler cap at the top of the case. Using a funnel, add the recommended quantity and type of oil. For the 2019 TE250i, fill to specified capacity (approx. 0.8–0.9 liters; check your owner's manual for the exact value).
    The 2019 TE250i features an oil check bolt on the clutch cover. Remove the oil check screw, slowly add oil until it just seeps out of the hole, then reinstall the check screw.

  6. Reinstall the Guard:
    Swing the skid plate or guard back into position and tighten both bolts securely.

  7. Check for Leaks and Test:
    Wipe the area around the drain plug and filling area to clean up excess oil. Start the bike and let it idle for several minutes. Check beneath the bike for oil leaks at the drain plug and filling/check bolt. After a short ride, recheck the oil level and inspect for leaks again.

Pro Tips and Model-Specific Notes

  • Do not overtighten the drain plug; stripped threads are a common issue.
  • Replace the crush washer or sealing ring at every change to prevent drips.
  • The sight/check bolt on the clutch cover acts as an oil level gauge. Add oil slowly and stop once it seeps out—overfilling is just as problematic as underfilling on the TE250i engine.
  • Change oil every 15 hours of use, or more frequently for heavy riding/competition.
  • Use only manufacturer-recommended oil for best clutch and gearbox performance.
  • Always consult your owner's manual for capacity, correct procedures, and torque specs.
