Step-by-Step Oil Change Instructions
-
Warm the Engine Briefly
- Start the bike and let it idle for a couple of minutes. This thins the oil and helps it drain more completely.
- Do not run the engine for long — you just want it warm, not hot.
-
Prepare the Bike
- Place the bike upright in a secure, level position (bike stand recommended).
- Lay out your oil catch pan beneath the engine drain plug.
-
Remove the Drain Plug
- Locate the transmission oil drain bolt. It's typically on the lower left side of the engine casing.
- Using your socket or wrench, carefully loosen and remove the drain bolt. Let the old oil completely drain into your catch pan.
- Inspect the removed bolt and crush washer. Replace the washer if it's worn or damaged to prevent leaks.
-
Remove the Filler Plug and Oil Level Screw
- The filler plug is located on the right side of the engine, and the oil level screw is on the clutch cover (lower right side).
- Remove both plugs – this allows air to enter so the oil drains more thoroughly and lets you monitor the correct refill level.
-
Replace and Torque the Drain Plug
- Once all oil has drained, clean the drain bolt and install a fresh washer if needed.
- Reinstall the drain bolt. Tighten to the torque spec specified in your owner’s manual (avoid overtightening).
-
Add Fresh Gear Oil
- Using a funnel, pour the correct type and quantity of oil (0.5L/500cc for the 2024 TC85) into the filler hole.
- With the bike level, watch for oil starting to trickle out the oil level check hole – when it does, the correct level has been reached. Stop filling and let excess drain out until just a trickle remains.
- Pro Tip: The 2024 TC85, like KTM 85 SX and GasGas MC 85, uses this method for checking oil level, so it's crucial the bike is straight up and down, not on the side stand, for accurate measurement.
-
Reinstall the Oil Level Screw and Filler Plug
- Clean any residual oil from the threads and surrounding area.
- Tighten both plugs firmly (see manual for torque specs).
-
Clean Up and Double-Check
- Wipe down any spilled oil. Double-check tightness of all fasteners.
- Start the bike briefly and check for leaks around the drain, fill, and level plugs.
Model-Specific Call-Outs for the 2024 Husqvarna TC85
- Oil capacity is 0.5L (500cc) of high-quality gear oil. Exceeding this may affect shifting; using less can reduce lubrication and lead to damage.
- The oil level check procedure requires the bike to be completely upright for accurate reading .
- Always replace the drain plug washer during each change to avoid oil leaks .
- Because the TC85 has no oil filter, regular changes are crucial for long-term transmission life (more so than many adult four-strokes).
- It is recommended to follow the more frequent oil change interval if riding in sandy, muddy, or race conditions .
Pro Tips from MotoSport.com for the Best Results
- Check your gear oil color at every change. If you see metallic flecks or the oil is extremely dark, check for excessive clutch or transmission wear.
- A measuring cup helps you avoid overfilling, especially if you don't have a new bottle pre-measured at 500cc.
- Document your oil changes (date, hours, and oil type) so you maintain a regular maintenance schedule.
