Maintaining the engine oil in your 2017 Husqvarna TC 65 is essential to keep your dirt bike running strong and to extend its engine life. Oil changes on the TC 65 are straightforward but require the right tools, patience, and careful attention to model-specific details. Below, you'll find a detailed step-by-step guide, a list of all required tools and supplies, and the critical tips every TC 65 owner should know before starting.

Tools and Supplies Needed

  • 13mm socket (for drain plug)
  • Socket wrench or ratchet
  • Measuring cup (to measure oil)
  • Drain pan (to catch old oil)
  • Clean rags (for cleaning and wiping up spills)
  • Engine oil – SAE 10W-40 gear oil, up to 500 ml (check your manual for specification)
  • Replacement O-ring or crush washer (recommended)
  • Funnel (optional, for pouring new oil)
  • Contact cleaner or brake cleaner (for cleaning the area around the drain and fill plugs)
  • Gloves (to keep your hands clean)

Pre-Oil Change Preparations

  • Warm up the engine for a few minutes. This helps the oil become less viscous and drain out more completely. Do not make the engine so hot that you risk burns.
  • Ensure your work area is clean and level. Place the bike upright, using a stand if available.
  • Make sure to have your drain pan and all your tools within reach.

Step-by-Step Oil Change Process

  • 1. Remove the Gear Oil Level Screw
    • Locate the gear oil level screw (often marked E00535-10). This is generally on the left side of the engine, behind the shifter.
      Tip: The outer area can collect dirt; clean it thoroughly to prevent contamination of the engine.
  • 2. Remove the Filler Plug
    • Unscrew the filler plug on the top of the clutch cover. This allows air to assist oil flow during draining and makes filling easier later.
  • 3. Remove the Drain Plug
    • Place the drain pan underneath and remove the 13mm oil drain bolt from the bottom of the engine. Let all oil completely drain into the pan.
      Model Call-Out: The TC 65 (2017+) has the oil drain located behind the shifter on the lower left, unlike larger Husqvarnas which may have multiple drains or screens.
  • 4. Inspect and Replace the O-ring or Crush Washer
    • Check the condition of the O-ring or crush washer on the drain plug. Replace if worn or damaged to avoid leaks.
      Owner’s Tip: These are inexpensive and prevent a lot of headaches from oil seepage. Keep spares on hand.
  • 5. Reinstall the Drain Plug
    • Once all old oil has drained, reinstall the drain plug (with new O-ring if replaced) and tighten to manufacturer’s specs (refer to your manual for torque specs).
  • 6. Add New Gear Oil
    • Using your measuring cup, measure out 500 ml (or as specified in your owner’s manual) of recommended gear oil (SAE 10W-40 or 15W-50, depending on preference and conditions).
    • Pour oil into the fill hole (located on the engine case) using a funnel for accuracy and cleanliness. Avoid overfilling.
      Model Call-Out: For the Husqvarna TC 65, the correct capacity is 500 ml. Overfilling can cause increased crankcase pressure and leaks.
    • When oil begins to flow back out of the oil level screw hole, you have reached the correct level.
  • 7. Reinstall the Oil Level Screw and Filler Cap
    • Replace both the level screw and the filler cap. Wipe down any spilled oil.
  • 8. Final Checks
    • Start the bike and let it idle for a minute. Turn off and check for leaks around the drain plug and fill cap. Add a little more oil if necessary (but do not exceed capacity).

2017 Husqvarna TC 65 Specific Call-Outs

  • The TC 65 shares its engine platform with KTM 65 SX and GasGas MC 65 models—procedure and oil capacity are the same across these bikes.
  • The correct drain bolt is 13mm. Do not use excessive force to avoid stripping.
  • Only fill to the point oil returns from the level check hole—overfilling will negatively affect clutch performance.
  • Recommended oil: SAE 10W-40 (some use 15W-50 depending on temperature/environment, but default is 10W-40).
  • Oil change interval: Check your manual, but a general rule is every 10-15 hours of ride time.
  • Dispose of old oil responsibly—never pour into drains or onto the ground. Most auto parts stores accept used oil for recycling.
