Changing the oil in your 2022 Husqvarna TE300i Rockstar Edition is an essential part of routine maintenance, ensuring your dirt bike’s gearbox longevity and peak performance. MotoSport.com brings you a detailed, proprietary guide tailored specifically for this model year and trim, highlighting everything you need to know for a flawless oil change.
Tools and Materials Needed
- 8 mm Allen wrench (for drain plugs)
- 17 mm wrench or socket (for oil fill plug)
- Drain pan
- Parts cleaning brush or rag
- Torque wrench
- Copper crush washer (genuine or third-party kit)
- New gearbox oil (15W/50 full synthetic, as per manual)
- Funnel
- Gloves and safety glasses
Preparation
- Warm up the engine for a few minutes to help the oil flow easily. Shut the engine off and let it cool just enough so it’s not too hot to touch.
- Park the bike on level ground and support it securely, ideally with a stand.
- Make sure all your tools and new oil are within reach to avoid mess and downtime.
Step-by-Step Oil Change Instructions
-
Remove the Oil Level Monitoring Screw
Locate the small screw on the right side of the case—this is your oil level monitoring screw. Loosen and remove it to allow proper oil draining and level checking later. Only a small quantity of oil should run out at normal level; if none comes out, that means the oil is low.
Specific call-out: This screw must be cleaned and reinstalled with the O-ring intact for a proper seal in the TE300i series. The torque spec is 8 Nm (5.9 lbf ft) for the M6 screw. -
Drain the Old Oil
Place your drain pan under the bike. Remove the gear oil drain plug (bottom of the case). Oil will begin to flow out, so be prepared for a rush of fluid.
Model-specific tip: The drain plug is magnetic. Clean it thoroughly with a rag or parts brush, ensuring all metallic debris is wiped away. The plug torque spec is 20 Nm (14.8 lbf ft) for the M12x1.5 plug. -
Replace the Crush Washer
Always replace the copper crush washer under the drain bolt to help prevent leaks. A generic kit will work, but be sure to match the washer size to your plug.
Pro tip: Owners report that skipping the crush washer is a common cause of slow leaks over time, so keep a few spares handy for each change. -
Refit and Torque the Drain Plug
Once drained and cleaned, refit the drain plug with its new washer and tighten to 20 Nm as specified by Husqvarna. Do not overtighten—stripping the case threads is a costly mistake. -
Remove the Filler Plug
The filler plug is on the right side cover (top of the clutch case). Remove it with a 17 mm wrench. -
Add Fresh Oil
Use a funnel to pour in 0.8 liters (0.8 qt) of 15W/50 full synthetic oil. Carefully pour until oil just begins to dribble out of the oil level check opening—this indicates the correct fill level.
Pro tip: Go slowly near the end to avoid overflow, as the TE300i case fills up fast. -
Re-Install the Level Check and Fill Plugs
Clean and reinstall the oil level screw and fill plug. Tighten both to manual torque specs: Level check (M6): 8 Nm, and fill plug: 20 Nm if not otherwise marked. -
Wipe Off Oil, Check for Leaks, and Test
Wipe any residue off the case. Start the engine and let it idle for a minute. Shut off and check for leaks around the drain plug and both screws.
Dispose of old oil responsibly at an authorized recycling facility.
2022 TE300i Rockstar Edition-Specific Tips
- This model uses a separate gearbox oil system (not premix for engine lubrication). Gear oil changes are every 10 hours or after every muddy/wet ride, according to best owner practices.
- The drain plug is magnetic to catch wear debris—always inspect for large metal flakes or chunks. Some paste-like residue is normal for break-in, but shavings mean urgent attention is needed.
- Monitor oil level visually using the sight screw; overfilling is just as bad as underfilling for clutch performance.
- Be careful with the O-rings on all screws, as the TE300i relies on them for sealing and longevity.
Recommended Oil Brands and Specifications
- 15W/50 full synthetic is the Husqvarna factory spec for the TE300i’s gearbox.
- Some riders choose Motorex Cross Power 4T or Motul Transoil–both are compatible with this 2-stroke clutch and gear system.
Final Thoughts
- Oil change intervals for aggressive riders can be shortened to 5–7 hours if you race or ride in extreme conditions.
- Keep your receipts and records of maintenance—this protects your warranty and helps with resale value.
