How to Change the Oil in a 2020 Husqvarna TC50
Shop parts for a 2020 Husqvarna TC50 Dirt Bike.
Keeping your 2020 Husqvarna TC50’s clutch and transmission healthy means committing to regular oil changes–ideally every ride or every 1-2 hours of engine time. The clutch oil in these 2-stroke mini motocross bikes takes a beating and degrades fast, so timely oil changes will drastically improve clutch life, performance, and reliability.
Tools & Supplies Needed
- 13mm socket and ratchet wrench (with extension recommended)
- Drain pan or suitable container for used oil
- New gear oil (consult your manual for recommended type–usually fully synthetic 75W or 80W gearbox oil)
- Clean rags
- Replacement crush washer/seal ring (recommended)
- Torque wrench (recommended; set for 20 Nm or 14.8 lbf ft)
- Funnel (for easy filling, optional)
2020 Husqvarna TC50 Oil Change Steps
- Warm up the engine for a couple of minutes. Take the bike for a short ride or let it idle–this helps the oil flow and drain completely. Shut off the bike and ensure it’s stable and upright, ideally on a triangle or side stand (not a center stand) for access and safety
- Remove the oil filler cap, located on the top/right of the engine, to aid draining and relieve pressure. Set it aside on a clean rag .
- Place your drain pan under the bike, right below the drain bolt (bottom of the engine case, often near the frame rail). Be sure your pan’s large enough to catch splashes and all used oil. A homemade catch bottle or pan works fine .
- Remove the drain bolt using a 13mm socket and ratchet. Be sure not to lose the drain bolt or the sealing washer. Allow the oil to fully drain–this may take a few minutes. Tilt bike slightly side to side to encourage full drainage if necessary .
- Thoroughly clean the drain bolt–especially if it has a magnetic tip, which will collect clutch debris. Wipe the bolt and clean the sealing surface on the engine for a tight, leak-free fit .
- Install a new crush washer/seal ring on the drain bolt, if available, to prevent leaks–a best practice for all oil changes on modern dirt bikes .
- Reinstall the drain bolt by hand and then tighten to 20 Nm (14.8 lbf ft) with a torque wrench. Do not overtighten, as this engine case is soft magnesium and can be damaged. Confirm the bolt is snug but not over-torqued .
- Pour in fresh gear oil. The 2020 Husqvarna TC50 takes 200ml (milliliters) of oil. Use a funnel for accuracy and to avoid spills. Insert the funnel into the filler hole and slowly pour in the measured quantity .
- Replace and tighten the filler cap. Ensure the threads are clean, and the cap snugs down securely, but don’t overtighten.
- Check for leaks. Wipe down any oil, start the bike, and let it run for a minute. Shut off and check under the bike for drips, especially around the drain plug.
- Dispose of oil properly by bringing used engine oil to a recycling center or auto parts store.
Model-Specific Callouts for the Husqvarna TC50 (2020)
- Drain Bolt Torque: The side case is magnesium, so always use a torque wrench at 20 Nm (14.8 lbf ft)–stripping is a risk with overtightening .
- Oil Quantity: Use exactly 200ml of gear oil; too much or too little can cause clutch and shift issues .
- Stand Usage: A triangle or side stand is preferred. Do not use a center stand for greater stability during draining .
- Drain Bolt Location: The drain is on the bottom of the right side case; ensure the area is clean prior to removal to prevent dirt from entering .
- Oil Change Interval: For racing or hard riding, change oil every ride or every 30-60 minutes–much more frequently than larger bikes due to tiny clutch volume and high stresses .
- Magnetic Bolt: Clean the magnet thoroughly each oil change–a lot of metallic debris in oil can signal clutch wear or transmission issues .
