A routine oil change is vital to keeping your 2019 Sherco 500 SEF FACTORY running at its best. This step-by-step guide walks you through the entire process, covering the specific tools, oil requirements, and important model-specific notes every owner needs to know.

Tools & Supplies Needed

  • Socket wrench with 8mm and 17mm sockets
  • 4mm Allen wrench
  • Oil drain pan
  • Funnel
  • Clean rags or shop towels
  • New oil filter (required every oil change)
  • New crush washers (for both drain bolts)
  • 1.2 liters of fully synthetic 4-stroke engine oil, viscosity 10W-50 or 10W-60
  • Gloves (recommended)

Preparation Steps

  • Warm up the engine for a few minutes to help the oil flow out easily, but never work on a hot engine to avoid burns.
  • Park the bike upright on a stable, level surface with the bike on a stand if available.

Step-by-Step Oil Change Procedure

  1. Remove the skid plate (if equipped):
    • Use the correct size socket or Allen wrench to detach the skid plate for better access to the drain bolts.
  2. Locate the drain bolts:
    • The 2019 Sherco 500 SEF FACTORY features two drain bolts on the engine’s underside. Each bolt has a crush washer, which should be replaced with every oil change for proper sealing.
  3. Drain the oil:
    • Place your oil pan under the drain area.
    • With an 8mm and 17mm socket, carefully remove both drain bolts and allow all old oil to drain out completely.
    • Be cautious; the oil may be hot. Allow several minutes for all oil to empty.
  4. Replace drain bolt crush washers:
    • Install new washers on both bolts before reinstalling. This helps prevent leaks.
  5. Reinstall and tighten drain bolts:
    • Thread bolts by hand to avoid cross-threading, then torque them firmly but do not overtighten. Check for the manufacturer’s torque spec in your manual, but do not use an impact wrench for this step (as per Sherco maintenance videos).
  6. Replace the oil filter:
    • Remove the oil filter cover with a 4mm Allen wrench.
    • Pull out the old filter. Wipe any old oil or debris from the filter cavity.
    • Install a new oil filter, ensuring the correct orientation as shown in your manual.
    • Reinstall the filter cover and secure it with the correct torque.
  7. Add new oil:
    • With a funnel, pour in 1.2 liters of fully synthetic 10W-50 or 10W-60 4-stroke engine oil

      .
    • Close the oil fill cap securely when finished.
  8. Run the engine and check oil level:
    • Start the engine and let it idle for 1–2 minutes to circulate the new oil.
    • Stop the engine and wait a couple of minutes for oil to settle, then check the oil level via the sight glass or dipstick. Add oil if needed, but do not overfill.
  9. Check for leaks:
    • Inspect around both drain bolts and the oil filter for any signs of leakage and re-tighten as necessary.
  10. Reinstall the skid plate (if removed):
  11. Dispose of used oil and filter properly:
    • Take all used oil and filters to a recycling center or hazardous waste facility. Never pour oil down drains or onto the ground

      .

Model-Specific Call-Outs and Tips

  • The 2019 Sherco 500 SEF FACTORY shares its oiling system and maintenance procedure with the 450 SEF FACTORY of similar years, but always verify details in the owner’s manual for proper torque specs and exact procedures.
  • Always replace the oil filter at every oil change as recommended by Sherco. Failing to do so could compromise engine performance and longevity

    .
  • Two drain bolts must both be removed—omitting one or forgetting its crush washer will cause improper draining or leaks.
  • Use only the recommended oil type and capacity—1.2 liters of fully synthetic 10W-50 or 10W-60 motor oil—for optimum performance and longevity, especially under tough riding conditions

    .
  • Do not use an impact wrench to remove or install drain bolts, as this can strip threads or damage the engine case.
  • Record your mileage or hours after each oil change to maintain proper service intervals.

Why Premium Oil Matters for Your Sherco 500

  • Fully synthetic oil ensures superior engine protection and performance—Sherco riders often subject their bikes to heavy loads and high heat, so using premium oil reduces the risk of engine wear or heat failure

    .

Performing an oil change on your 2019 Sherco 500 SEF FACTORY isn’t just routine maintenance—it’s a key investment in your bike’s future. Always use quality parts, follow each step carefully, and consult your manual or MotoSport.com for additional support or product recommendations.
