Oil Change Steps for 2019 Husqvarna FC450 Rockstar Edition
-
Warm up the Engine
- Start your FC450 and let it idle for 3-5 minutes. This thins the oil, ensuring it drains more completely.
- Shut the engine off and place the bike upright on a stand.
-
Remove Skid Plate (if equipped)
- Use the appropriate tool to remove the skid plate for better access to the oil drain bolts and screens.
-
Remove the Oil Fill Cap
- Unscrew the oil fill cap on the right side of the cylinder head to allow air in and help oil drain out faster.
-
Drain the Engine Oil
- Locate the two oil drain bolts underneath the engine.
- Place the drain pan directly beneath them.
- Remove the primary drain bolt and allow most oil to drain.
- Remove the secondary drain bolt (used to access/clean the oil screens).
- Let the oil fully drain for several minutes.
-
Clean and Inspect Oil Screens
- Use a pick to remove the oil screen(s) from their bores. On the FC450, there are usually two.
- Clean the screens with contact cleaner and inspect for debris.
- Reinstall clean screens when done.
-
Replace and Torque Drain Bolts
- Install new crush washers on both drain bolts to prevent leaks.
- Thread the bolts in by hand first to avoid cross-threading.
- Tighten both to manufacturer-spec torque (refer to the manual, generally 10-15 Nm/88-132 in-lb for most Husqvarna drain bolts) .
-
Replace the Oil Filter
- Remove the filter cover (usually held by two or three bolts on the right engine case).
- Take out the old filter. Compare it with the new one to ensure correct size & fit.
- Pour a small amount of fresh oil on the new filter (priming) and install it into the housing .
- Clean the filter cover sealing surface and reinstall the cover, tightening the bolts to spec.
-
Add Fresh Oil
- Pour in the recommended amount: 1,200 ml (1.2 liters) per the manufacturer. Always verify in your specific owner’s manual .
- Do not overfill. Use a measuring cup for accuracy.
- Reinstall and tighten the oil fill cap.
-
Run and Check Oil Level
- Start the bike and let it idle for about 3 minutes.
- Shut off, wait 2-3 minutes for oil to settle, then check the oil level via the sight glass on the right side of the engine.
- Oil should be between halfway and three-quarters up the sight glass .
- Add more oil if needed, but do not exceed maximum.
-
Reinstall the Skid Plate
- Install your skid plate, secure it, and wipe off any oil residue from the bike and the shop floor.
-
Properly Dispose of Used Oil
- Pour used oil into a sealed container and recycle it at your local motorcycle dealer, auto parts store, or community center.
2019 FC450 Rockstar Edition: Model-Specific Notes
- Always use premium, fully synthetic motorcycle oil (10W-50 recommended) to maintain engine life and performance.
- The FC450 includes two oil screens – clean both during every oil change for optimal lubrication and to spot early signs of engine wear.
- The sight glass is your friend. Overfilling can cause excessive crankcase pressure and leaks, so watch the oil level closely after each change.
- If your bike has a cold start button (under the throttle body), verify it returns to the basic position after the job. This affects how the engine runs after any maintenance involving oil or fuel .
- Take care not to over-tighten the oil filter cover bolts or drain bolts to avoid stripping the aluminum threads.
- Check for oil leaks around the drain bolts, filter cover, and sight glass after your first ride post-change.
Service Intervals
- Change engine oil and filter every 10-15 engine hours for maximum race reliability.
- For recreational riding, intervals can extend up to every 20 engine hours, but always inspect oil condition and level frequently .
