2019 Husqvarna TC85 Specific Call-Outs

  • Oil Capacity: 500cc (0.5L) of gear oil is required for the TC85. It’s the same spec as its platform siblings, the KTM 85 SX and GasGas MC 85. Overfilling or underfilling can impact performance and reliability.
  • Drain and Fill Plug Placement: The drain bolt is located at the bottom of the engine. The fill plug is on the right side case cover. There’s also a gear oil level bolt which helps you confirm proper fill.
  • Crush Washer: Always inspect the copper crush washer on the drain plug. Flip it over for reuse if it’s not deformed, or replace it for a leak-free seal.
  • Magnetic Drain Plug: The drain plug is magnetic. Finding metal shavings on it is normal during initial break-in periods. Clean the magnet thoroughly during every oil change.

Step-by-Step Oil Change Instructions

  • Warm up the engine.
    Run the bike for a few minutes to warm the gear oil. Warm oil flows more freely and carries contaminants with it. Allow the engine to cool until you can handle parts comfortably.
  • Stabilize and prepare the bike.
    Place your {strong}TC85{strong} on a stand with the bike upright and level. Remove the skid plate if equipped (recommended for access).
  • Locate and remove the drain bolt.
    Position the drain pan under the engine. Using a ratchet and appropriate socket, remove the drain bolt from the bottom of the right engine case.
  • Allow the oil to drain completely.
    Let the oil drain fully into the pan. Tilt the bike side to side gently if needed to encourage all oil to escape.
  • Inspect the drain plug.
    Examine the drain plug for debris. Clean any metal shavings from the magnet. Check the copper crush washer; flip it for reuse, or replace if worn or deformed. Most can be used twice if flipped.
  • Reinstall the drain plug.
    Thread the plug back into place by hand, carefully to avoid cross-threading. Tighten firmly, but don't overtighten. Consult the owner's manual for torque spec if using a torque wrench.
  • Remove the fill plug.
    The fill plug is found on the right side case cover. Remove it with a socket or Allen key as required.
  • Set the bike upright for proper filling.
    Keep the bike perfectly vertical. Using a funnel, pour in the specified amount (500cc) of fresh gear oil. For best results, fill slowly and avoid overfilling.
  • Check the oil level.
    On the TC85, confirm oil level by removing the gear oil level screw. Add oil until it just begins to weep out of the level hole. When it stops dripping, reinstall both the level and fill plugs.
  • Reinstall covers and clean up.
    Replace any skid plates or guards. Wipe up spilled oil and ensure everything is secure.
  • Dispose of old oil responsibly.
    Take the drained oil to an approved recycling facility or retailer.

Pro Tips for the 2019 Husqvarna TC85

  • Change the oil after the initial break-in period and every 5–10 hours of riding, depending on riding conditions.
  • Inspect the color and smell of the old oil—milky appearance can indicate water contamination.
  • Stick to high-quality motorcycle-specific gear oil. Avoid automotive oils, which may not provide proper clutch protection for wet clutch systems.
  • Keep the threads clean and start all plugs by hand to prevent cross-threading.
  • If unsure about torque specs, refer to the Husqvarna Owner's Manual for your TC85.
