Shop parts for a 2022 Husqvarna FC350 Dirt Bike.

Changing the oil in your 2022 Husqvarna FC350 is a critical maintenance task to ensure peak performance and a long engine life. Performing this at regular intervals will help to keep internal components lubricated and running smoothly. Below is a step-by-step proprietary MotoSport.com guide, highlighting specific tips and call-outs for this exact make and model.

Tools and Materials Needed

  • 13mm wrench (A standard socket will not fit easily behind the skid plate for the main drain bolt.)
  • 8mm socket or wrench (for oil filter cover bolts)
  • Drain pan
  • Clean rags or paper towels
  • Needle-nose pliers (to remove oil screen)
  • New oil filter (always replace during oil changes)
  • Engine oil (approximately 1.1 quarts is required for the FC350)
  • New crush washers and O-rings (recommended for drain bolt and oil screen for each oil change)
  • Funnel (optional, but helps prevent spills)
  • Torque wrench (for re-tightening to manufacturer spec)

Step-by-Step Process

  1. Warm up your bike
    • Run the engine for a minute or two to bring the oil up to temperature. Warm oil drains more thoroughly, carrying particulates with it.
  2. Stabilize your motorcycle
    • Place your FC350 on a solid stand or triangle stand, ensuring it is upright and steady.
  3. Remove the oil fill cap
    • Loosen or remove the oil cap on the right side of the engine before draining. This helps the oil flow freely and fully.
  4. Drain the engine oil
    • Position your drain pan under the engine. Using your 13mm wrench, carefully remove the main oil drain bolt on the left side. Take caution as the oil may be hot.
      Tip: Place the drain bolt and washer on your rag to avoid losing them.
  5. Remove and clean the oil screen
    • With needle-nose pliers, gently pull the oil screen (located below/near the drain bolt) out of the engine case. Lay it on a clean paper towel.
    • Clean the oil screen thoroughly. Inspect it for metal particles – a sign of internal wear.
    • Replace the O-rings/crush washer on the oil screen if worn or flattened, and lightly coat the O-rings with fresh engine oil before reinsertion.
  6. Remove and replace the oil filter
    • The oil filter is covered by two 8mm bolts on the right (clutch) side of the engine. Remove the cover using your 8mm socket or wrench.
    • Take out the used oil filter and dispose of it appropriately.
    • Install a new oil filter. If your replacement requires pre-oiling, lightly coat it with fresh engine oil before installation.
      Note: Ensure the filter is seated correctly. If not seated, oil bypass could occur, risking engine damage.
    • Inspect and replace cover O-rings if necessary.
    • Reinstall and tighten the oil filter cover to manufacturer torque spec (typically around 8 Nm, check your owner’s manual).
  7. Reinstall the oil screen and drain bolt
    • Place the cleaned oil screen back into its port, making sure it seats in the correct groove to maintain a proper seal. Misalignment here can allow debris past the screen, risking engine damage.
    • Replace the crush washer on your drain bolt. Thread it in by hand first to avoid cross-threading, then torque it to spec (usually around 15 Nm).
  8. Refill with fresh oil
    • Using a funnel, pour new engine oil into the fill port. The 2022 FC350 takes 1.1 quarts of oil.
    • Reinstall and hand-tighten the oil filler cap.
  9. Check the oil level
    • Ensure the motorcycle is upright and on level ground. Use the sight glass or dipstick (as applicable) to confirm the oil level lands between the upper and lower marks.
    • Start the engine and let it idle for a minute, then shut off. Wait 1-2 minutes and recheck oil level, adding a small amount as needed. Do not overfill.
  10. Dispose of old oil and filter
    • Properly recycle both your used engine oil and oil filter according to your local environmental regulations.
  11. Final Inspection
    • Wipe up any spilled oil and inspect for leaks around the drain plug, oil screen, and filter cover. If you see seepage, recheck torque on these components.
    • Go for a short test ride and check again for leaks on return.

Model-Specific Callouts for the 2022 Husqvarna FC350

  • The 13mm drain bolt location is notably tight; a socket may not fit, so a box-end wrench is optimal for removal and reinstallation. Some users report difficulty accessing this bolt with standard sockets due to frame and skid plate geometry.
  • Inspect both oil screen O-rings and drain bolt crush washer each time. Replace them with new parts if crushed, flattened, or damaged to prevent leaks.
  • Always seat the oil screen fully into its groove. Misalignment can result in oil bypassing the screen and allow metal fragments to reach vital engine parts, risking expensive damage.
  • The correct oil capacity is 1.1 quarts – do not overfill. If necessary, add in small increments and check the level carefully.
  • Refer to the latest owner’s manual or service guide for torque specifications for both the drain bolt and the filter cover to avoid under- or over-tightening.
  • Do not mix oil types. Use a high-quality motorcycle-specific four-stroke oil with the correct viscosity recommended for your region and riding conditions.
