Lawn Mower Parts -Hex lock nut M8, Stock #: 303010359

Got the part and no instructions on how it gets installed???

Thanks for the $20 for positive review

Shipping cost seemed a bit high.

Fits perfect

Need a belt cover for a b8621s self propelled mower, but it seems that this model doesn't exist and it's not very old. I received another cover that won't fit and they make it extremely difficult to return the part, All belt covers supposedly are on back order, I need a 203050396c and can't get one
