If you ride a 2024 Husqvarna TC250, keeping your bike’s oil fresh is crucial for performance and engine longevity. This guide details every step, lists the tools required, and highlights model-specific notes for the TC250.

Tools and Supplies Needed

• Socket wrench and 12mm socket (for drain bolt)
• Flathead screwdriver or pick tool (for oil screen)
• Drain pan
• Oil filter (OEM recommended)
• Crush washer (replace each oil change)
• Measuring cup (at least 1 liter capacity)
• Funnel (small size recommended, especially with 1-liter bottles)
• Service manual for torque specs and capacities
• Workshop gloves
• Rags or shop towels
• Contact cleaner or brake cleaner spray
• Plastic skid plate removal tool (if equipped)

Preparation

• Clean the motorcycle thoroughly before starting, especially around the drain and fill areas. This prevents dirt contamination during the oil change process, which is especially important for the TC250’s high-tolerance engine parts.
• Warm up the engine briefly (2–3 minutes) to allow used oil to flow out more completely. Do not overheat.
• Turn off the engine and ensure the bike is upright and stable on a stand.

Step-by-Step Oil Change Process

• Remove the skid plate (if equipped):
  • Use the required tools to remove the plastic skid plate to access the drain bolt. This step ensures you can easily reach the oil drain bolt and avoid making a mess.
• Locate and remove the oil drain bolt:
  • The bolt is typically on the bottom of the engine case. Use a 12mm socket to remove it.
  • Be prepared for oil to begin draining immediately after the bolt is loosened. Use a drain pan to capture all fluid and avoid spills. Exercise caution—the bolt and oil may be hot if the engine was warmed up.
• Remove and inspect the oil screen and crush washer:
  • Behind the drain bolt, the TC250 has a single oil screen (not a traditional plug strainer). Using a small pick or flathead screwdriver, carefully remove the screen. On some model years, this may require finesse—the screen is sometimes a snug fit.
  • Inspect the screen for metal debris, and carefully wipe it clean. Replace the crush washer with a new one each time to prevent leaks.
• Replace and tighten the oil screen and drain bolt:
  • Slide the clean oil screen back into place, ensuring it sits fully and correctly inside the bore as designed (open ends through the bore if possible).
  • Thread the drain bolt and new crush washer in by hand, then tighten to the factory torque spec (refer to your owner’s manual for the exact value).
• Remove and replace the oil filter:
  • Remove the oil filter cover using the correct wrench or Allen. Take out the old filter and dispose of it properly.
  • Lubricate the seal on the new oil filter with a drop of fresh oil and install. Re-fit the cover, torqueing the bolts as specified.
• Refill with fresh oil:
  • The 2024 Husqvarna TC250’s factory specification is approximately 0.7 liters of oil. However, with slight leaning, some owners add just a touch more, not exceeding the sight glass or overflow hole.
  • Pour oil through the designated fill port using a small funnel for precision. Some oil bottles include a spout which can make pouring easier.
• Check the oil level:
  • Replace the fill cap and ensure it’s secure.
  • Start the engine and let it run for 30–60 seconds, then turn off and let the oil settle for a minute.
  • With the bike upright, check the oil level via the sight glass or level check port. Add oil if necessary, never exceeding the recommended level.
• Reinstall the skid plate and clean any spilled oil from the bike’s surfaces.

Model-Specific Callouts for the 2024 Husqvarna TC250

• Oil Type: Use only the manufacturer-recommended oil. Motorex is the usual factory fill, and properly rated synthetic 2T gear oil is best for the transmission (since the TC250 is a two-stroke engine).
• Oil Capacity: The recommended capacity is 0.7 liters (700ml); always confirm by the sight glass or level bolt.
• Screen Design: Some older Husqvarna models used a dual-screen design, but for the 2024 TC250, there is a single, sturdy oil screen accessible behind the drain bolt. Be sure the screen is cleaned and re-installed correctly.
• Crush Washer: Always use a fresh crush washer for the drain bolt each change—this is inexpensive insurance against leaks.
• Service Intervals: Change the oil every 10–15 hours of runtime, or after particularly hard or muddy riding. Short intervals are recommended for high performance two-stroke engines to maximize reliability.
• Cleaning Is Key: Cleanliness is especially critical—a dirty oil fill or a contaminated oil screen can endanger your precision engine.

Final Tips

• Dispose of the old oil and filter responsibly at a local recycling center.
• Record the date and hours on your maintenance log. Consistency ensures your TC250 continues to perform at its peak.
• If you’re unsure about any torque specifications or procedures, always refer to your Husqvarna owner’s manual or consult with a MotoSport.com parts expert for guidance.

Keep your 2024 TC250 running at its best, and ride with confidence—proper maintenance is the best protection for your investment.
