Step-by-Step Guide: Changing Oil on Your 2017 Husqvarna TC85BW
-
Prepare Your Work Area
- Put your bike on a stable stand to keep it upright and level.
- Warm up the engine for a few minutes to help the old oil drain more easily. (But avoid overheating: just a couple of minutes at idle will suffice.)
- Gather all your tools and place the drain pan under the gearbox drain plug.
-
Remove the Oil Drain Plug
- Locate the gearbox oil drain bolt on the underside of the engine case.
- Using the correct socket, loosen and remove the bolt, allowing the old oil to fully drain into your pan.
- Be careful—the oil may be hot.
-
Inspect and Clean
- Examine the drain plug: Wipe it clean and check for metal fragments or debris. A few small shavings are normal, but excessive metal could signal a bigger problem.
- Clean the bolt and sealing surfaces thoroughly.
-
Reinstall the Drain Plug
- Once the oil flow has stopped, re-install the drained and cleaned plug.
- Use a torque wrench to tighten it to the manufacturer's recommended specification (consult your owner's manual for the exact torque, typically around 10–15 Nm, but always verify).
-
Refill with Fresh Gearbox Oil
- Locate and remove the fill cap or inspection bolt on the right side of the engine.
- With the funnel, pour in 500 ml (about 0.53 quarts) of fresh gear oil. Do not overfill.
- If your bike has an inspection window or level bolt, stop pouring once oil begins to trickle out with bike held upright – this confirms the proper level .
- Replace the fill cap and tighten securely.
-
Run and Recheck
- Start the bike and let it idle for a minute to circulate the new oil.
- Shut it off and allow it to sit for a few minutes.
- Recheck the oil level with the fill cap/dipstick or inspection bolt; top off if necessary.
-
Dispose of Used Oil
- Pour the old oil into a sealed container and take it to your local recycling facility. Never pour it down the drain or onto the ground.
