Step-by-Step Oil Change Instructions
-
Warm Up the Engine
- Start and idle the bike for 5-10 minutes. The oil needs to be warm so it drains effectively and carries away more contaminants. Don’t overheat; a quick loop around the block is enough.
-
Remove the Skid Plate (if equipped)
- Use the appropriate socket to remove the skid plate. This step prevents a mess and makes access to the drain plugs easier.
-
Position the Bike and Supplies
- Place your oil drain pan directly under the engine drain plug. Make sure the bike is upright and stable, using a stand if needed.
-
Remove the Main Drain Plug
- Using a 13 mm socket, remove the main drain plug located under the engine. Take care—the oil may be hot.
- Allow oil to drain completely. Clean the plug and replace the crush washer with a new one to ensure a leak-free seal.
-
Remove Oil Screen and Filter Screws
- There are multiple screws: the main drain screw, long filter screw, and short filter screw. Remove each in turn with the appropriate socket.
- Remove the oil screens (mesh filters) and inspect for metal debris or excessive contamination. Clean with contact cleaner, then reinstall if in good condition.
- Clean all mating surfaces with a lint-free rag to ensure a proper seal when reinstalling.
-
Reinstall Screws and Drain Plug
- Reinstall oil screen and screws in reverse order. Torque each screw to manufacturer’s specs: main drain screw (typically 11-15 ft-lbs—confirm with your manual).
-
Replace the Oil Filter
- Locate the oil filter cover on the right side of the engine and remove the cover screws with an 8 mm socket.
- Carefully remove the cover and old filter (snap ring pliers may help).
- Lubricate the new filter’s rubber O-ring with fresh engine oil and install the filter in the correct orientation.
- Reinstall the filter cover, torquing the screws as specified.
-
Add Fresh Oil
- Remove the oil fill cap and insert a funnel.
- Pour in the manufacturer-recommended amount of oil (1.3 quarts, Motorex 10W-50 is standard for the FE 501S).
- Reinstall and tighten the oil fill cap.
-
Check Oil Level
- Start the engine and let it idle for 1-2 minutes. Shut it off and wait 1 minute. Check the oil level with the bike upright and top off if needed.
-
Reinstall Skid Plate and Clean Up
- Wipe away any oil residue, reinstall your skid plate, dispose of old oil and filter properly, and note the mileage/hours for your maintenance records.
2020 Husqvarna FE501S-Specific Call-Outs
- Oil Capacity: Confirm 1.3 quarts for your model—always check your manual in case there’s been modification.
- Crush Washer: Always use a new copper crush washer on the main drain plug—reusing may cause oil leaks.
- Filter Fitment: Only use filters made for the FE501S. Incorrect filter sizing or orientation can result in oil starvation.
- Engine Protection: Leaving skid plate off post-oil change can cause damage; ensure it is torqued correctly and installed before riding.
- First Service: Husqvarna recommends an initial oil change after 1 hour of operation for break-in metals, then at regular service intervals thereafter.
- O-Rings: If the oil filter cover has an O-ring, always inspect for cracks and replace if required.
Final Tips
- Cleanliness is key: Wipe down around drain and fill plugs before removing to avoid introducing grit into the engine.
- Always check for leaks after your first ride post-maintenance.
- Disposal: Bring old oil and filters to an approved recycling center.
