Tools and Supplies Needed

  • Socket wrench set (especially an 8mm or 13mm socket, check your service manual for the exact drain bolt size)
  • Torque wrench
  • Drain pan
  • New gear/transmission oil (refer to your manual for oil specification and quantity)
  • Replacement crush washer (recommended, not always required)
  • Clean rag or shop towel
  • Funnel (ideally a flat “drifter” type funnel if you have a skid plate installed)
  • Contact or brake cleaner (optional, for cleaning the area)
  • Rubber gloves (optional, keeps your hands clean)

Before You Begin

  • Warm up the engine for a few minutes to thin the oil, making it easier to drain.
  • Ensure your TX 300 is on a stable stand.
  • If you have a skid plate, you may want to either remove it or use a specialty funnel to prevent a mess beneath the bike

Step-by-Step Oil Change Guide

  1. Locate the Drain Plug
    • The drain bolt is on the right side of the engine case, typically in a horizontal or slightly downward-facing position. The 2023 TX 300 uses a side-case drain plug that can be accessed without full skid plate removal if you use a thin funnel

      .
  2. Position the Drain Pan and Loosen the Bolt
    • Place the drain pan under the plug. Carefully loosen (do not fully remove) the drain bolt with your socket wrench. If using a funnel, slide it between the skid plate and the case so oil funnels directly into your drain pan

      .
  3. Remove the Drain Bolt and Allow Oil to Drain
    • Once the bolt is almost out, remove it by hand; oil will begin to flow immediately. Let it completely drain for several minutes for best results.
  4. Inspect and Replace the Crush Washer
    • Remove the old crush washer from the drain bolt. Inspect it for wear or distortion; replace it with a new washer to prevent leaks.
  5. Clean and Reinstall the Drain Bolt
    • Wipe the drain bolt with a clean rag. Reinstall the bolt with the new or inspected washer. Tighten the bolt to the proper torque spec (consult your manual; for most Husqvarna 2-strokes, this is typically 12 Nm, but always verify for your model).
  6. Remove the Fill Plug and Add New Oil
    • Locate and remove the transmission/gear oil fill plug – usually on the right side, higher up the case.
    • Using a clean funnel, add the recommended amount and type of oil for the 2023 TX 300 (for 2023 models, this is usually Motorex Gear Oil 10W-50 or manufacturer equivalent, and the capacity is approximately 0.7 liters (700ml), but always check your owner’s manual or the decal near the fill cap)

      .
  7. Check the Oil Level
    • Some TX 300s use a sight glass or a level bolt to confirm correct quantity. Run the engine briefly, then check and top off if necessary.
  8. Inspect for Leaks
    • Wipe the area clean. Start the engine, let it run for a minute, and check for drips or leaks. Re-tighten the bolt if needed, but do not overtighten.
  9. Dispose of Used Oil Properly
    • Take the old oil to a proper recycling facility. Never throw oil in the trash or pour it down a drain.

  • The drain plug is readily accessible, but if you have an aftermarket or thick skid plate, either remove it or use a thin funnel to direct the oil safely

    .

  • Change interval: Husqvarna recommends changing the oil every 10-15 hours of use, or after hard race/riding sessions

    .
