Keeping your 2019 Husqvarna TC50 in peak condition means regular oil changes for the clutch&gear system. Frequent oil changes not only extend clutch life but also maintain transmission performance for every ride. This step-by-step MotoSport.com guide will show you how to efficiently change the oil in your TC50, highlighting specific tips and call-outs unique to this make, model, and year.

Tools and Supplies Needed

  • 13mm socket and ratchet wrench (plus possible extension bar for easy access)
  • Drain pan or suitable container for catching oil (e.g., an old bottle or oil catch pan)
  • Funnel for clean oil pouring
  • Replacement oil – use 200ml of high-quality gear oil (refer to your manual for specific oil recommendations)
  • New crush washer or seal ring for drain bolt (highly recommended)
  • Cleaning rags
  • Torque wrench (for precise reinstallation of bolts, recommended torque: 20 Nm or 14.8 ft-lb for M12x1.5 drain plug)
  • Gloves (optional, but great for keeping your hands clean)

Step-by-Step: Changing the Oil on a Husqvarna TC50

  • 1. Preparation:
    • Warm up the engine briefly (2–3 minutes) to help the oil flow more freely.
    • Turn off the engine and position your bike on a level surface using a plug-in or triangle side stand — avoid the center stand during an oil change for better draining stability.
    • Have all tools, fresh oil, and rags ready to minimize downtime.
  • 2. Remove the Oil Filler Cap:
    • Locate and unscrew the oil filler cap on the right side of the engine. This allows air in, helping the old oil drain smoothly.
  • 3. Drain the Old Oil:
    • Place your drain pan under the engine's drain plug, which is found at the bottom of the clutch cover.
    • Using your 13mm socket, carefully loosen and remove the oil drain plug to let the oil flow out.
    • Allow several minutes for the oil to drain completely. Tilting the bike slightly can help remove every last drop. Be patient – residual oil needs time to escape.
  • 4. Inspect and Clean the Drain Plug:
    • The TC50's drain plug is magnetic – wipe it clean of any metal debris and inspect for excessive build-up.
    • Replace the crush washer or seal ring if it appears damaged or worn (failure to do so may cause leaks).
  • 5. Refit the Drain Plug:
    • Thread the cleaned drain plug (with new washer, if used) back into position and hand tighten initially.
    • Finish tightening with a torque wrench to 20 Nm (14.8 ft-lb) for the M12x1.5 plug.
  • 6. Add New Gear Oil:
    • Using a funnel, pour exactly 200ml of the manufacturer-recommended oil into the oil fill hole.
    • Pour slowly to avoid overflow and spills.
  • 7. Reinstall the Oil Filler Cap:
    • Securely reinstall the oil fill cap, ensuring the sealing surface is clean.
  • 8. Clean Up and Inspect:
    • Wipe down any oil residue from the engine exterior and check for leaks around the drain plug and fill cap.
    • Start the engine and let it idle for 1–2 minutes to circulate the new oil. Shut down the engine and inspect for leaks again.

Model-Specific Notes and Call-Outs

  • 2019 Husqvarna TC50 shares many components with the KTM 50 SX – most oil change instructions are interchangeable, but always verify drain plug size and oil volume.
  • Oil Change Frequency: For best clutch and gear system life, change the oil every 1–2 hours of riding – much more frequently than larger four-stroke bikes, due to the small oil volume and high clutch temperatures.
    Neglecting regular changes can lead to rapid clutch wear and poor shifting performance.
  • Drain Plug Torque is critical: Over-tightening may cause thread damage; under-tightening may lead to leaks.
  • Use an oil catch pan that fits the low-slung design to avoid messes, as clearances are tight below the engine.
  • Be mindful of parts compatibility: TC50 owners often find aftermarket or KTM-branded parts on their bikes (e.g., a KTM drain plug). Function remains unaffected, but sealing washers and finish may differ.

Final Tips

  • Keep meticulous oil change records: Track riding hours and oil changes for optimal maintenance planning and resale value.
  • Dispose of used oil responsibly: Take it to a certified recycling facility or auto parts retailer that accepts used oil.

Changing the gear oil on your 2019 Husqvarna TC50 is one of the simplest – yet most crucial – maintenance tasks you can perform. Following this MotoSport.com guide ensures better performance, longer clutch life, and hassle-free rides every time you hit the track or trail.

Ride smart, ride safe – and keep your Husky running strong.
