Remove oil filter/strainer cover.(5mm hex and 8mm socket) Position bolts in the same pattern as removed.Inspect o-ring.
Check o-ring on oil fill cap/plug for damage and missing.
This is what you should see when the cover is removed.
Oil filter/strainer. Notice the junk? If damaged replace with Yamaha Part Number: 5HO-13440-09-00 Spray WD-40 or low pressure air from inside out to remove junk.
Clean the oil filter cavity. Note o-ring on bottom bolt hole. Inspect.
Install cleaned filter/strainer- this end goes in first.Your filter MUST have the four holes like this one. I don't care what the parts dept. says.There have been WAY TOO MANY ENGINE FAILURES due to mislabeled filter boxes. FOUR SLOTS & FOUR HOLES!!!! Refer to above part number for the correct filter/strainer.
You should now see this.If so, replace cover.
Replace everything you removed and fill with oil to this level, shown with the bike upright.
Start the motor and loosen the bolt with the phillips head several turns.(10mm wrench) Oil should run out of here. If not shut the motor off and reinspect the filter.
This is not all inclusive of how every bolt should be removed or tightened. This is for those who feel confident enough to change their oil and when in doubt, ASK !!
I hope you enjoy this,..............Rick.
