How to Change the Oil in a Yamaha Majesty 400

Step 1. Run the engine for a minute to warm the oil, which makes it less viscous and helps it drain faster.

Step 2. Remove the oil fill cap/dipstick from the right side of the crankcase to allow the engine to vent properly, and also for the oil to drain faster.

Step 3. Put a drain pan under the engine, then remove the 12mm drain bolt and crush washer from the lower-left rear side of the crankcase and let the oil drain out.

Step 4. Inspect the crush washer and replace it if necessary. Next, reinstall the drain bolt and crush washer and torque them to 14.5 foot-pounds.

PRO TIP: The crush washer should be replaced after every 3-4 oil changes regardless of its condition to prevent leaks from the drain bolt.

Step 5. Move the drain pan underneath the front of the crankcase, then remove the three 8mm oil filter cover bolts and the cover itself. Inspect the O-ring inside the cover and replace it if necessary.

Step 6. Remove the old oil filter and install the new oil filter.

NOTE: Pay attention to the direction the old filter is facing and install the new filter facing the same direction.

Step 7. Reinstall the oil filter cover and tighten the bolts to about 7.5 foot-pounds.

Step 8. Fill the engine with 1.8 quarts of 10W40 motor oil

Step 9. Reinstall the oil fill cap/dipstick, then start the engine and let it idle for half a minute to circulate the oil within the engine. Next, shut off the engine and let it sit for a minute to allow the oil to settle.

Step 10. Remove the oil fill cap/dipstick and wipe it clean, then set it into the fill hole without screwing it in. Take the oil fill cap/dipstick out again and read the oil level, then top off the oil if necessary and you’re done.
