Changing the oil in your 2020 Husqvarna TE300i is a fundamental part of dirt bike maintenance that ensures the longevity and smooth operation of your transmission. This step-by-step guide, proprietary to MotoSport.com, provides all the details, tools, and critical model-specific callouts you’ll need to perform this essential service.

Tools and Materials Needed

  • Ratchet wrench or socket wrench
  • 13mm socket (to fit both drain and fill plugs)
  • Torque wrench (essential for accuracy on reinstallation)
  • Drain pan (to catch used oil)
  • Papers towels or shop rags
  • Replacement oil: Full synthetic 15W-50 is recommended
  • New sealing or crush washer/O-ring (for the drain plug)
  • Funnel (optional, but helps avoid spills)
  • Gloves (to keep hands clean and safe)

Important Call-outs for the 2020 TE300i

  • This bike uses approximately 0.8 liters (0.8 qt.) of gear oil. Do not overfill or underfill.
  • The drain plug is magnetic—inspect for metallic debris when removed.
  • The manufacturer specifies 15W-50 full synthetic oil. Using the correct viscosity is vital for proper protection.
  • Torque specifications are critical. Drain plug should be tightened to 20 Nm (14.8 lbf ft); level screw to 8 Nm (5.9 lbf ft).
  • Let the engine cool before starting, but warm oil drains more completely. Run the bike for 2–3 minutes, then shut off and wait a few minutes.

Step-by-Step Oil Change Process

  1. Preparation
    • Park the bike on a level surface and ensure the engine is warm, not hot.
    • Use the bike’s stand or secure it upright to avoid tipping.
    • Place the oil pan directly beneath the engine’s drain plug.
  2. Draining the Oil
    • Locate the drain plug (underneath the case cover on the right side, 13mm).
    • Loosen and remove the drain plug carefully. Allow oil to drain completely—this may take several minutes.
    • While draining, remove the filler plug (on the clutch-side engine cover) to allow air in and speed up the draining process.
  3. Inspect and Clean
    • Examine the magnetic tip of the drain plug for excess metal debris—fine sludge is normal, but chunks indicate wear.
    • Clean the plug thoroughly; replace the sealing washer or O-ring for a proper seal.
    • Wipe down any spilled oil from the engine area.
  4. Replace the Drain Plug
    • Reinstall the drain plug and hand-tighten. Use a torque wrench to finish tightening to 20 Nm (14.8 lbf ft) as per the service manual.
  5. Add New Oil
    • Insert a funnel into the filler port.
    • Pour in 0.8 liters of 15W-50 full synthetic engine oil slowly.
    • Check the oil level using the oil level check screw. Remove the screw just below the fill port—oil should just begin to run out of this hole when filled properly.
    • If no oil comes out, add a small amount until it does.
  6. Final Assembly and Check
    • Reinstall the oil level check screw with its O-ring and tighten to 8 Nm (5.9 lbf ft).
    • Install the filler cap.
    • Start the bike briefly to circulate oil, then turn it off and check for leaks.
    • Wipe down any spilled oil for a clean finish.
  7. Dispose of Used Oil Responsibly
    • Pour old oil into a suitable container and recycle at your local waste facility.

Model-Specific Tips for the 2020 Husqvarna TE300i

  • The magnetic drain plug is easily stripped if overtightened. Always use a torque wrench.
  • O-ring/gasket on the drain plug should be replaced at each oil change to prevent leaks.
  • The oil level check screw can also be stripped if over-tightened—hand tight and then to spec is best.
  • Always double-check manual specs, particularly if you have post-market parts or skid plates that may hide fasteners.

Conclusion

Regular oil changes are among the most critical maintenance items for your 2020 Husqvarna TE300i’s reliability and performance.
