Shop parts for a 1996 Yamaha PW50 Dirt Bike.
Changing the transmission oil on your 1996 Yamaha PW50 is a crucial part of basic maintenance. Doing so not only extends the lifespan of the bike but also keeps it running smoothly—especially important for a popular entry-level dirt bike. Follow this comprehensive, MotoSport.com-exclusive guide to ensure a successful, mess-free oil change, and to learn a few model-specific callouts.
Tools and Supplies Needed
- 12mm socket and ratchet (or box end wrench)
- Drain pan (to catch old oil)
- Measuring cup (capable of measuring up to at least 0.3L)
- Funnel
- Rags (for cleanup)
- Fresh transmission oil (Yamalube or comparable, 80W-90 is a common choice for this model)
- New crush washer (recommended to replace each change)
- Rubber gloves (optional, for cleaner hands)
PW50 Oil Change Frequency
- If your bike is new: First month of use, then again at 6 months.
- For all other bikes: Annually, regardless of riding frequency.
Step-by-Step Instructions
-
Warm up the Engine Briefly
Run the engine for a couple of minutes. This helps the oil flow out more easily and removes more contaminants from the system.
(Never run the bike in an enclosed area.) -
Prepare Your Work Area
Place the bike on a stand or level ground. Put your drain pan underneath the transmission case, directly below the drain bolt. -
Remove the Drain Bolt
Using the 12mm socket, carefully remove the transmission oil drain bolt. Allow the old oil to drain completely into the pan.
Be careful—the oil can still be hot. -
Remove the Filler Cap
Take off the oil filler cap on the right side of the chassis (behind the side cover). This allows air into the system so the oil drains more thoroughly.
Wipe the cap to clean the dipstick before reinstalling later.
-
Inspect and Replace the Crush Washer
Each time you change the oil, replace the crush washer on the drain bolt. This helps prevent leaks and ensures a tight seal.
If you see metal particles on the magnetized part of the drain bolt, wipe them off—they–re normal, but excess material may indicate wear. -
Reinstall the Drain Bolt
Once the oil has completely drained, reinstall the drain bolt with the new washer. Tighten it carefully—use a torque wrench if possible.
The official torque spec for the drain bolt on the 1996 Yamaha PW50 is 14 N·m (10 lb·ft).
Do not overtighten; this bolt threads into aluminum and is easily damaged. -
Refill with the Correct Oil
Use a clean funnel to pour in 0.30 liters (300 ml) of the recommended transmission oil through the filler hole. Do not overfill.
For most climates, 80W-90 gear oil is common, but always check your riding conditions and owner–s manual for recommendations. -
Reinstall the Filler Cap
Replace and tighten the filler cap securely. -
Dispose of Used Oil Properly
Take the used oil to an approved recycling center. Never dump oil in the trash, on the ground, or down the drain.
PW50-Specific Callouts
- Oil Types: The PW50 uses a separate 2-stroke injector oil system for the engine. The process above is for the transmission oil only. Keep the 2-stroke oil tank topped up–behind the number plate–with high-quality 2-stroke injector oil.
- Drain Bolt Location: On all PW50 model years, including 1996, the transmission drain bolt is easily accessible on the left side of the engine case. Do not confuse it with other bolts nearby.
- Oil Quantity: Accurate measurement is critical. Overfilling or underfilling will affect transmission performance. Always use exactly 0.30L (0.32 US qt) for oil changes, as specified by Yamaha.
- Routine Inspection: While changing oil, inspect for leaks around both the drain bolt and filler cap. Check for stripped threads–aluminum cases are soft.
- Clean Filler Cap: The filler cap features a dipstick; make sure it–s wiped clean before reinstalling for an accurate reading on the next check.
Frequently Asked Questions
- Can I use automotive oil instead of motorcycle oil? For best results and longevity, always use oil recommended for motorcycle transmissions. Generic oils can cause clutch and gear problems over time.
- What if I see metal in the oil? Minor amounts are normal in used oil from this type of transmission. Excessive metal could mean internal wear—consult a technician if in doubt.
- Is there an oil filter? The PW50 uses a magnetic drain bolt to collect debris and does not have a replaceable filter.
Final Tips
- Track Your Intervals: Jot down the date and hours ridden after each change to keep a consistent maintenance schedule.
- Store Extra Oil: The PW50 uses a small amount per change, so one bottle can last for several oil changes.
- Safe Riding: Never ride immediately after an oil change without double-checking for leaks and proper oil fill.
Routine oil changes are one of the best ways to protect your PW50–s performance and resale value. MotoSport.com recommends following Yamaha–s guidelines for a fun and trouble-free riding experience.
