Shop parts for a 2019 Husqvarna TE300i Dirt Bike.

Changing the transmission oil in your 2019 Husqvarna TE300i is essential for maintaining optimal clutch and gearbox performance. This step-by-step guide, proprietary to MotoSport.com, will walk you through each part of the process, including specific tips for your bike.

Tools and Supplies Needed

  • Socket wrench set (with appropriate metric sockets)
  • Torque wrench
  • Oil drain pan
  • Clean rags or shop towels
  • Flathead screwdriver (for removing skid plate, if necessary)
  • New crush washer (recommended for each oil change)
  • Funnel
  • Motorex 15W50 full synthetic oil (or other manufacturer-recommended oil)
  • Gloves

Specific Considerations for 2019 Husqvarna TE300i

  • The TE300i features a fill plug, drain bolt, and oil level check/overflow bolt accessible without removing the skid plate, though space can be tight for large hands.
  • The recommended oil spec is 15W50 full synthetic (see owner's manual for confirmation).
  • Oil capacity is approximately 800 ml (0.8 L), but always fill only until oil trickles from the level check bolt.
  • Always use or replace the crush washer on the drain bolt to prevent leaks.
  • Torque specs are important: the drain and level plugs are typically torqued to 11 ft-lbs (15 Nm) (check your service manual for current values).

Step-by-Step Oil Change Instructions

  1. Warm the Engine Slightly
    • Run the engine for a few minutes. Warm oil drains more easily and carries away more contamination.
  2. Position the Bike and Access the Drain Plug
    • Secure the bike on a stand or level surface.
    • If needed, remove the skid plate for easier access, though on the 2019 TE300i it’s usually not necessary due to the drain plug’s location (see reference video) .
  3. Remove the Fill and Level Bolts
    • Unscrew the fill cap to allow air in during draining.
    • Loosen, but do not remove yet, the oil level check/overflow bolt (on the side of the case).
  4. Remove the Drain Plug
    • Place your drain pan beneath the transmission-case drain plug (bottom side of the engine).
    • Carefully remove the drain plug and allow all oil to drain.
    • Inspect the magnetic drain plug for metal debris–normal to find some metal paste during break-in, but large flakes may indicate an issue .
    • Clean the drain plug and replace or clean the copper crush washer .
  5. Reinstall the Drain Plug
    • Install the cleaned drain plug and new crush washer.
    • Torque to manufacturer spec (approx. 11 ft-lbs / 15 Nm).
  6. Add New Oil
    • Using a funnel, pour oil slowly into the fill hole.
    • Stop once oil begins to flow from the level check/overflow port.
    • Let excess drain until flow nearly stops, then reinstall the level plug (torque to 7 ft-lbs / 10 Nm, verify with manual) .
  7. Reinstall Fill Cap
    • Secure the fill cap and wipe down any spilled oil.
    • If removed, reinstall the skid plate.
  8. Final Inspection
    • Start the engine and let it idle for a minute.
    • Check for leaks at both plugs and ensure proper clutch function.
    • Dispose of old oil responsibly at your local recycling center.
