Keeping your 2018 Husqvarna TE250 running smooth and performing at its best starts with regular oil changes. Although this is a manageable do-it-yourself project, a few specific steps and tools apply for your Husky’s two-stroke gearbox oil. Below, MotoSport.com details every step, outlines the gear you’ll need, shares model-specific notes, and highlights tips that guarantee a seamless change. Let’s get your TE250 trail-ready.

Tools & Materials Needed

  • Sockets/wrenches:– 8mm for engine guard, 13mm or 17mm for drain bolt (verify your size ahead.)
  • Ratchet & extension:– For easier bolt access
  • Torque wrench:– For correct reassembly
  • Oil drain pan:– 1 quart/liter minimum capacity
  • Replacement oil:– SAE 10W-40 motorcycle gear oil (approx. 0.80L or 0.85qt)
  • New drain plug washer (crush washer):– To ensure no leaks
  • Clean rags/paper towels
  • Funnel:– Optional but helps to prevent spills
  • Contact/brake cleaner:– To clean oil residue
  • Nitrile gloves:– To keep your hands clean

Preparation

  • Start the motorcycle and let it run for 2-3 minutes. A warm engine helps oil drain more completely (avoid burns; engine should be warm, not hot).
  • Park the bike on a solid, level surface and put it on a stand.
  • Gather all tools and materials before you begin.

Step-by-Step Oil Change for 2018 Husqvarna TE250

  1. Remove the skid/engine guard:–
    • Locate the two bolts securing the lower engine or skid plate. Use an 8mm socket/ratchet to remove them.
    • Gently lower or swing down the guard for easy access to the drain bolt underneath the engine.
  2. Drain the Oil:–
    • Place your drain pan directly below the oil drain bolt.
    • Use the appropriate socket and extension (commonly 13mm or 17mm) to loosen the drain bolt. The bolt is found at the lowest point of the engine case.
    • Carefully remove the bolt and washer (it may fall into the drain pan–so have your fingers ready.). Allow oil to drain fully. Wait several minutes for complete drainage.
    • Inspect the magnetic tip of the drain bolt for metal debris and clean thoroughly. Also, wipe the surface around the drain opening.
  3. Replace the Drain Bolt:–
    • Install a new crush washer on the bolt. This is crucial for sealing and leak prevention.
    • Screw the drain bolt back in by hand. Use your torque wrench to tighten to 20 Nm (14.8 lbf ft) as per the owner’s manual recommendation. Do NOT overtighten to avoid stripping the threads (Shop manual for a 2018 Husqvarna TE250 Dirt Bike.).
  4. Add New Oil:–
    • Locate and remove the oil fill cap on the clutch side of the engine.
    • Insert a funnel for spill-free pouring.
    • Pour in 0.80 liters (0.85 quarts) of fresh SAE 10W-40 motorcycle gear oil.
  5. Check and Adjust Oil Level:–
    • There’s a small inspection/check bolt labeled “oil” on the engine case. Remove this with a wrench.
    • Oil should be level with the bottom of this hole (with the bike upright and on level ground). Add or remove oil as needed.
    • Reinstall and torque the inspection screw to 10 Nm (7.4 lbf ft).
  6. Reinstall the Engine Guard:–
    • Lift the guard/skid plate back into position and secure with its hardware.
  7. Double-Check and Clean Up:–
    • Wipe down any drips with contact cleaner.
    • Start the engine and let it idle for a minute. Inspect for leaks around the drain and fill plugs.
    • Double-check torque and add oil if the level has dropped in the inspection window.

Special Call-Outs for the 2018 Husqvarna TE250

  • Oil Capacity:– This year uses 0.80L/0.85qt–overfilling can compromise clutch function and create extra pressure (Shop manual for a 2018 Husqvarna TE250 Dirt Bike.).
  • Magnetic Drain Plug:– The drain bolt contains a magnet–always inspect for excessive metallic particles, a sign of internal wear (Shop manual for a 2018 Husqvarna TE250 Dirt Bike.).
  • Recommended Oil:– Use only high-quality SAE 10W-40 motorcycle gear oil, not standard automotive oil. Check your owner’s manual for brand and add-pack specifics (Shop manual for a 2018 Husqvarna TE250 Dirt Bike.).
  • Oil Change Interval:– For normal use, change every 15-20 hours of riding. For racing, more frequent changes (as low as every 3-5 hours) may be advisable, especially if shifting feels “notchy” or clutch performance drops (Shop manual for a 2018 Husqvarna TE250 Dirt Bike.).
  • Tightening Torque:– Double check that drain and fill bolts are not overtightened–stripped threads are a common DIY pitfall.
  • No Cartridge Filter:– The two-stroke TE250 uses only a gear oil change–NO replaceable cartridge oil filter (unlike Husky 4-strokes).

Helpful Tips

  • Be patient with oil drainage; letting the last drops escape removes contaminants.
  • Always use a new crush washer for leak prevention.
  • Dispose of used oil according to environmental regulations–never pour it down drains or onto the ground.

Proper and timely oil changes will help keep your 2018 Husqvarna TE250 performing at its peak, whether blitzing enduro races or hitting your favorite trail. For premium parts, OEM crush washers, and the exact gear oil, visit MotoSport.com—your source for all things dirt bike.
