Tools and Materials Needed

  • Sockets/Wrench Set (particularly 14mm for drain bolt)
  • Drain Pan for used oil collection
  • New Oil Filter (Yamaha 5H0-13440-09-00 or equivalent)
  • New Crush Washer (14mm, recommended for drain plug)
  • Engine Oil (2 quarts of SAE 10W-40, preferably Yamalube, or approved synthetic)
  • Disposable Funnel
  • Clean Rag or Shop Towels
  • Optional: Torque wrench, rubber gloves

Model-Specific Call-Outs

  • Recommended Oil:– SAE 10W-40 (Yamalube or premium synthetic), or SAE 20W-40 Type SE Motor Oil per some service guides. Always check your owner's manual for local climate recommendations.
    Oil capacity:– 1.3 L (1.38 US qt) for a standard oil change; 1.4 L (1.48 US qt) when replacing the oil filter as well.
    Oil Change Interval:– Every 6,000 kilometers (approx. 4,000 miles), or more often for severe use or dirt riding.
    Crush Washer:– Install a new 14mm crush washer every change to ensure a tight seal and prevent leaks.
    Filter Access:– The oil filter is housed behind a side cover which is easily accessible; make sure to clean around the area to prevent dirt from entering when removed.

Step-by-Step Instructions

  1. Warm Up the Engine
    Start the bike and let it idle for a few minutes. Warm oil flows better and removes more contaminants from your engine. Do not get the engine too hot–just warm to the touch.
  2. Position the Bike Safely
    Place your XT350 on a level surface, using a center stand or secure the bike upright.
  3. Prepare Work Area
    Place a drain pan under the engine's oil drain bolt. Have your tools and new materials ready for quick switch-over to minimize spillage.
  4. Remove the Drain Plug
    Use the 14mm socket or wrench to carefully loosen and remove the drain bolt at the bottom of the crankcase. Be cautious as oil may be hot. Let the oil completely drain—this can take several minutes.
    Tip:– Inspect the old crush washer and replace it with a new one for proper sealing.
  5. Remove and Replace the Oil Filter
    Locate the oil filter cover on the right side of the engine. Clean around it before removal to avoid contamination.
    Remove the three bolts holding the oil filter cover; pull the cover and filter away gently. Inspect the filter cover O-ring and replace if worn or pinched.
    Install the new oil filter (with the open side facing outward, per instructions/markings) and refit the cover.
    Tighten all oil filter cover bolts snugly, but don't over-tighten.
  6. Reinstall Drain Plug
    Wipe the drain plug clean, install the new crush washer, and thread it by hand to avoid cross-threading. Tighten the drain bolt to manufacturer spec (consult your manual–typically around 22-25 Nm).
  7. Refill with Fresh Oil
    Remove the oil fill cap/dipstick. Insert your funnel, and add 1.3 L (1.38 US qt) of oil for a change without filter, 1.4 L (1.48 US qt) if you changed the filter.
    Allow a minute for oil to settle, then check the dipstick. Do not overfill. Top up in small increments if needed.
  8. Start Engine and Check Oil Level
    With the bike upright, start the engine and let it idle for 1-2 minutes; turn it off and wait another minute for oil to drain back into the sump.
    Check the oil level again with the dipstick–add oil if required. Refit the fill cap securely.
  9. Clean Up and Dispose of Used Oil
    Wipe up any spilled oil and double-check for leaks at the drain plug and filter cover.
    Properly recycle used oil and the old filter by taking them to an authorized recycling center.
  10. Final Safety Check
    Take a brief test ride and then check underneath the bike for any leaks. Re-inspect the oil level; adjust if necessary.

Additional Tips and Best Practices

  • Always use a new oil filter every oil change to maximize engine protection.
  • If the oil has any metallic particles or a burnt smell, further inspection of the engine is advised.
  • Keep records of dates and mileage for each oil change for maintenance tracking.
  • Consider using full synthetic oil (Cyclemax Full Synthetic 10W-40 or AMSOIL) for extended durability, especially if riding hard or in challenging conditions.

Proper and timely oil changes are an investment in your Yamaha XT350's long life and strong performance.
