Regularly changing the oil (specifically the clutch/gear oil) in your 2017 Husqvarna TC50 is critical to ensure smooth clutch operation and prolong engine life. This comprehensive guide, proprietary to MotoSport.com, walks you through the tools required, detailed step-by-step instructions, and model-specific tips unique to your 2017 TC50 youth motocross bike.

Tools and Supplies Needed

  • Gear Oil – Use a high-quality gear/clutch oil as recommended in your owner's manual.
  • Ratcheting Socket Wrench
  • 13mm Socket (for drain plug removal)
  • Oil Drain Pan or Suitable Container
  • Funnel
  • New Sealing Washer/O-Ring for Drain Plug (replace if worn)
  • Clean Rags
  • Gloves (optional, for cleanliness)

Preparation

  • Start with the bike completely cool on a flat, stable surface.
  • For stability and safety, put the TC50 on a plug-in stand or bike lift to keep it upright.
  • Locate the oil filler cap (on the right engine case near the clutch lever) and the oil drain plug (bottom of the engine case, typically with a magnet for debris collection).

Step-by-Step: Changing the Oil

  1. Remove the Oil Filler Cap
    • Unscrew the oil filler cap to allow air flow; this will help the oil drain faster and more completely.
  2. Place the Drain Pan
    • Slide a suitable oil catch pan directly under the drain plug to ensure you capture all used oil.
  3. Remove the Oil Drain Plug
    • Using a 13mm socket, loosen and remove the oil drain plug located on the bottom of the engine.
    • Be careful as the oil may be warm and can drain quickly.
    • Allow all the oil to drain completely into the pan.
  4. Clean the Drain Plug
    • Inspect the plug—on the 2017 TC50, it's typically magnetic to catch metallic debris. Wipe it thoroughly, removing all residue and particles.
    • Replace the sealing washer or O-ring if it appears damaged or worn out; this will prevent leaks.
  5. Reinstall the Drain Plug
    • Screw the plug back in by hand to start, avoiding cross-threading.
    • Torque the plug to 6 Nm (4.4 lbf ft) if it's the smaller M6 plug, or 20 Nm (14.8 lbf ft) for the larger M12x1.5, as specified in your manual. Always double-check plug size for your exact bike configuration.
  6. Add New Oil
    • Using a clean funnel, pour the manufacturer-recommended amount and type of fresh gear/clutch oil into the open filler.
    • For the 2017 Husqvarna TC50, capacity is approximately 0.20 liters (200cc) of gear oil.
    • Stop periodically to check the level via the sight glass or dipstick (if equipped). Fill only up to the recommended level—overfilling can cause clutch issues.
  7. Replace the Oil Filler Cap
    • Secure the filler cap snugly to prevent leaks.
  8. Dispose of Used Oil
    • Transfer the old oil to a sealed container and take it to your nearest recycling or hazardous waste facility. Oil should never be poured down drains or onto the ground.

Model-Specific Notes for the 2017 Husqvarna TC50

  • This model uses a wet clutch system, so always use a gear/clutch oil meeting Husqvarna’s requirements to avoid clutch slippage.
  • The drain plug is magnetic, designed to catch fine metallic debris. Inspect and clean it thoroughly each change—persistent debris may be a warning sign of abnormal internal wear.
  • Do not overfill—excess oil can cause pressure build-up and clutch drag. The correct oil quantity is crucial.
  • If the drain or filler plug gasket is compromised, always replace it during oil changes to prevent leaks and contamination.
  • Check owner's manual for any revised torque specs or updated oil recommendations—model revisions can occur, even within the same year.

Final Checks and Start-Up

  • Wipe off any oil residue from the outside of the engine cases and around the filler/drain plugs.
  • Start the engine and allow it to idle for a minute.
  • Shut off the engine and wait a minute. Recheck oil level and top up if necessary—small air pockets in the clutch cover may affect the initial reading.
  • Inspect for leaks around the filler and drain plugs while the engine runs.

Why Regular Oil Changes Matter

  • Keeping clean oil in your 2017 Husqvarna TC50 ensures smooth shifting, reliable clutch performance, and longer gearbox life.
  • Beyond scheduled intervals, consider changing the gear oil more often if racing or riding in harsh conditions.
