Shop parts for a 2014 Husqvarna TC85 Dirt Bike.

Changing the oil in your 2014 Husqvarna TC85 is critical to keeping your bike performing at its best. Follow this robust guide, proprietary to MotoSport.com, for an expert, model-specific oil change. This process applies both to Small Wheel (17/14) and Large Wheel (19/16) versions.

Tools and Materials Needed

  • Socket set (check the size for your drain and filler plugs)
  • Allen key set (for oil drain and filler plugs, usually 8mm or 10mm)
  • Oil drain pan
  • Measuring cup (to pour the correct oil amount)
  • Fresh gear oil (500cc, as per Husqvarna/KTM 85 recommendations)
  • Shop towels or rags
  • Goggles and gloves for protection
  • Torque wrench (recommended for correct plug tightness)

Specific Call-Outs for the 2014 Husqvarna TC85

  • Oil Capacity: Use 500cc of gear oil for the transmission; make sure you don't overfill.
  • Oil Type: Use a quality two-stroke gear oil (consult your manual or dealer for exact viscosity rating).
  • Oil Level: The correct oil level is up to the bottom edge of the oil level screw opening—do not guess; use a measuring cup.
  • Check for leaks: After installation, briefly run the engine and check drain and level/filler plug areas for leaks.

Step-by-Step Instructions

  1. Prepare the Bike
    • Ensure the bike is cool to touch before starting.
    • Place the TC85 securely upright on a stand to level the transmission for accurate draining and refilling.
  2. Remove the Drain Plug
    • Position the oil drain pan under the crankcase drain plug (usually on the bottom left side).
    • Use the proper Allen key or socket to remove the drain plug. Be careful: oil may be hot if the bike was recently run.
    • Allow oil to fully drain – this may take several minutes.
  3. Clean and Inspect Components
    • Check the drain plug for excessive metal particles or debris on the magnetic tip (if equipped).
    • Wipe the plug and the sealing surface clean.
    • Inspect the crush washer or sealing washer and replace if necessary.
  4. Reinstall the Drain Plug
    • Reinstall the drain plug by hand, then tighten to spec (see your owner's manual for recommended torque).
    • Do not overtighten: aluminum cases can strip easily.
  5. Remove the Filler and Oil Level Plugs
    • The filler plug is usually on the right side of the engine cover; remove it using the appropriate tool.
    • The oil level check bolt (K00976-10) is typically located on the clutch cover's lower right side. This bolt lets you check for correct oil fill level.
  6. Pour in New Oil
    • Using a measuring cup, pour exactly 500cc of recommended gear oil through the filler port.
    • Wait a minute to allow settling.
    • With the bike upright and level, remove the oil level check bolt and verify that oil lightly trickles out—this confirms proper fill level.
    • If no oil comes out, add slowly until it does. If too much flows out, let it drain until oil is level with the hole's bottom edge.
  7. Reinstall Filler and Level Plugs
    • Reinstall and gently tighten both the filler plug and the oil level check plug.
    • Clean any oil residue from the case and plugs.
  8. Dispose of Old Oil Properly
    • Pour used oil into a container and take it to a designated oil recycling center.
  9. Start and Re-check
    • Start the bike and let it idle briefly.
    • Check around the drain and filler plugs for leaks and tighten slightly if necessary.

Additional Tips

  • Warm oil drains more easily—consider running the engine for a minute, then allow it to cool.
  • Change oil after every few rides or as specified in your manual for maximum engine life.
  • Always record the date and hours of each oil change.

Model-Specific Insights for 2014 Husqvarna TC85

  • The 2014 TC85 (19/16 or 17/14) uses 500cc of gear oil for the transmission–not standard engine oil, since it is a 2-stroke with a separate gearbox.
  • Always refer to your owner's manual for torque specs, recommended oil type, and intervals. Husqvarna generally recommends changing oil every 6000 kilometers for most engines, but for high-performance models like the TC85, more frequent changes based on riding conditions are advised.
  • Avoid overfilling, as it can cause gearbox pressure issues or leaks through breather hoses.

Maintaining your Husqvarna TC85 with regular oil changes keeps your transmission shifting smoothly and extends engine life. For all your gear oil and tool needs, trust MotoSport.com—the dirt bike experts.
