Shop parts for a 2017 Yamaha PW50 Dirt Bike.

Changing the transmission oil in your 2017 Yamaha PW50 is a crucial part of routine maintenance that keeps your bike running smoothly and extends transmission life. Below you'll find a proprietary step-by-step guide crafted specifically for MotoSport.com readers, with all the unique call-outs you need to know for the PW50.

Tools and Supplies Needed

  • 12mm socket and ratchet
  • Torque wrench (capable of 10 ft-lb)
  • Drain pan (to catch old oil)
  • Clean rags or shop towels
  • Replacement crush washer/gasket (recommended every change)
  • Funnel (for adding oil)
  • Measuring cup (metric, for precision)
  • Recommended transmission oil: Yamaha recommends a specific oil—see owner’s manual, but typical requirement is 0.30 L (300 ml) of Yamaha Transmission Oil or a high-quality motorcycle transmission oil that meets manufacturer specs
  • Gloves (optional, for cleanliness)

PW50-Specific Call-outs

  • The Yamaha PW50 uses transmission oil only; the engine is a 2-stroke and does not use engine oil as in 4-strokes.
  • Do not use oils with a diesel specification of "CD" or higher than specified, and avoid "ENERGY CONSERVING II" or higher-rated oils to prevent clutch slippage.
  • Always check the O-ring on the fill cap and replace if damaged to prevent leaks.
  • Warm up the engine slightly before draining the oil to reduce viscosity and speed up the process.
  • The oil change interval is every 6000 km (about 4000 mi) for most Yamaha engines, but check and change more often if you ride in harsh conditions.
  • Tighten the drain bolt to exactly 10 ft-lb (14 Nm).

Step-by-Step Guide

  1. Warm up the bike: Start and let idle for a few minutes. This helps the oil drain more thoroughly.
    (Be cautious: the engine and oil may get hot—use gloves.)
  2. Place the bike on level ground: Use a paddock stand or have a helper hold the bike upright to ensure a complete drain.
  3. Locate the drain plug: Found on the bottom of the transmission case. You’ll use your 12mm socket here.
  4. Place the drain pan underneath: Catch all the old oil.
  5. Remove the drain plug: Use the 12mm socket to break it free. Take care not to lose the crush washer. Allow all the oil to fully drain.
    Tip: Removing the fill cap at this stage (on top of the case) aids oil flow for a thorough drain.
  6. Inspect and clean: Wipe down the drain plug and inspect for debris or metal fragments, which can indicate internal wear.
  7. Install new crush washer: Always use a fresh washer to prevent leaks.
    Thread in the drain plug by hand to avoid cross-threading.
  8. Tighten the drain plug: Torque to 10 ft-lb (14 Nm) with your wrench.
    Over-tightening can strip the threads; under-tightening can cause leaks.
  9. Refill with new oil: Using the funnel, add 300 ml (0.30 L) of recommended oil through the fill hole. Measure precisely—overfilling may cause leaks and foaming.
  10. Replace and tighten the fill cap: Check the O-ring for damage before reinstalling.
    Hand-tighten firmly, but do not over-torque.
  11. Start the engine: Let it idle for several minutes. Check for oil leaks at the drain and fill plug.
  12. Final inspection: With bike upright, verify oil level if your model has a sight plug or recheck that you’ve added the correct amount.

Owner Reminders and Pro Tips

  • Never mix chemical additives or use unsuitable oils, as this can severely damage the clutch and transmission.
  • Dispose of used oil responsibly—never pour down drains or onto the ground. Many auto shops or MotoSport locations offer recycling.
  • This procedure is valid for all Yamaha PW50 models, including 2017, but always consult your manual for the latest specs and recommended oils.
  • After every oil change, keep an eye out for fresh leaks for the first couple of rides—and re-check the drain plug torque if you notice weeping.

Conclusion

Changing the oil in your Yamaha PW50 is quick and easy, especially with the right tools and know-how. Following these MotoSport.com steps ensures you keep your bike in top shape for every ride. Always reference your specific owner's manual for the latest updates and ride safe.
