Replacement filter o-ring
Replacement drain plug gasket
The Yamaha Grizzly 600's engine oil should be changed every six months after the initial break-in period. During the initial break-in period -- the first month of use -- it should be changed at the one-month interval. Changing the oil in your Grizzly 600 is simpler than changing the oil in a car, but the procedure is only recommended for experienced home mechanics. The type of engine oil recommended by Yamaha varies.
Park your Grizzly on level ground. Gather the tools needed to change the oil.
Remove the three Phillips screws from the left side engine cover. Pull this cover off. Start the engine and let it run for about five minutes (to warm up), then turn it off. Place your oil drain pan underneath the Grizzly.
Twist off the oil filler cap -- it's also the dipstick -- and set it aside in a safe place. Remove the oil drain plug with a socket wrench; it's located on the underside of the Grizzly. Allow the oil to drain into the pan for about 10 minutes.
Remove the three bolts that secure the engine oil filter cover -- from the side you removed the engine cover from. Pull the oil filter straight off.
Remove the oil filter o-ring (found on the underside of the oil filter cover) and the drain plug gasket. They cannot be re-used.
Insert the new oil filter into place. Insert the oil filter o-ring into the oil filter cover. Re-attach the oil filter cover; tighten the bolts to 7.2-foot-pounds of torque.
Attach the new drain plug gasket to the engine oil drain plug. Replace and tighten the engine oil drain plug to 17-foot-pounds of torque.
Add the replacement oil through the oil filler port, using a funnel. The Grizzly 600's capacity is 2.1-quarts. If you ride in temperatures from below zero to 30 degrees F, Yamaha recommends 5W-30 oil; from 10 degrees F through 100 degrees F, Yamaha recommends 10W-30; from 40 degrees F through 120 degrees F, Yamaha says to use 20W-40 oil. Replace the engine oil filler cap and tighten it well.
Start the engine; let it run for a few minutes while you check underneath for oil leaks.
