Routine oil changes are a crucial part of keeping your 2022 Husqvarna TC50 performing at its best. The TC50 has a unique two-stroke engine that uses a separate gearbox (or clutch) oil system, not a traditional four-stroke engine oil system. This guide walks you through every step—making your next oil change quick, clean, and effective.

Tools and Supplies Needed

  • Gear (Clutch) Oil – Use only the oil grade recommended in your owner's manual for Husqvarna TC50
  • Funnel
  • Measuring Cup – For accurate oil filling
  • Drain Pan or Oil Catch Container
  • Torque Wrench
  • 13mm Socket (check your drain plug size to confirm, as some use M6 or M12 plugs)
  • New Seal Ring for drain plug (recommended)
  • Shop Towels or Rags
  • Safety Gloves (optional, but recommended)

Preparation Steps

  • Warm up the engine for a minute or two to let the oil flow more easily—do not overheat it. Then let the bike cool just enough to handle safely.
  • Stand the TC50 upright on a level surface using a bike stand.
  • Ensure you're working in a well-ventilated area away from flammable materials.

Step-by-Step Oil Change Process

  1. Locate the Drain Plug:
    • The drain plug for gearbox oil is found at the bottom of the engine case. Consult your owner's manual if you have difficulty finding it.
  2. Drain the Gearbox Oil:
    • Place your drain pan directly underneath the drain plug.
    • Use your socket and wrench to unscrew the drain plug.
    • Allow the oil to drain completely. Tip the bike slightly to each side if necessary to ensure full drainage.
    • Be careful not to lose the drain plug or the sealing washer.
  3. Clean and Inspect the Drain Plug:
    • The TC50 drain plug contains a magnet designed to catch fine metal debris.
    • Thoroughly clean the drain plug and the magnet with a rag. Check for a significant amount of metal shavings; a small amount is normal, but excessive debris could signal internal wear.
    • Replace the sealing washer with a new one for optimal leak prevention.
  4. Reinstall the Drain Plug:
    • Screw the drain plug back into the engine case by hand at first to prevent cross-threading.
    • Using your torque wrench, tighten the plug to specification (6 Nm for M6 plug or 20 Nm for M12 plug–confirm the size on your model).
  5. Add New Gear Oil:
    • Locate the filler cap on the side of the engine.
    • Using your funnel, pour in the recommended grade and amount of gear oil (see owner's manual; typically 200 ml for TC50 models).
    • For best results, use a measuring cup to avoid overfilling.
  6. Check the Oil Level:
    • Most TC50s have a visual level check screw above the drain bolt. Remove this screw; oil should just trickle out. Add oil slowly and re-check as needed.
    • If there is no check screw, refer to the measured amount provided in your owner's manual.
  7. Secure the Filler Cap:
    • Wipe away any spilled oil and tighten the filler cap.
  8. Dispose of the Old Oil:
    • Transfer used oil to a local recycling center–never pour it down drains or onto the ground.

Model-Specific Call-Outs for the 2022 Husqvarna TC50

  • Only change the GEAR/CLUTCH oil – this is a two-stroke engine. Do not add oil to the gasoline or try to find a conventional oil filter as with four-strokes.
  • Drain plug size is critical – the 2022 TC50 uses either an M6 drain plug (6 Nm torque) or M12x1.5 plug (20 Nm torque). Incorrect torquing can lead to leaks or stripped threads. Always check your specific bike before tightening.
  • Do not overfill – Overfilling causes excess pressure and potential leaks or shifting issues. Measure oil precisely and confirm via the level check screw if your model has one.
  • Inspect for excess debris on the magnetic drain plug, which can signal gear or clutch wear.

Final Checks

  • Run the engine briefly, shut it off, then check beneath the bike for leaks.
  • Double-check oil level after the first ride; top off if needed according to the manual.

Conclusion

Changing the gear oil in your 2022 Husqvarna TC50 is a straightforward job that protects your investment and keeps your clutch and gears functioning smoothly. Proper tools, careful measurement, and attention to the manufacturer's specs ensure a spill-free, reliable oil service every time.
