WRONG! WRONG!! WRONG!!! On the model BV2500, there's no need to remove any screws on the BLACK fan housing nor on the ORANGE motor housing - you'll make it much harder than it needs to be. Instead, simply push the black fan housing release button on the upper handle near the power switch and the fan housing will tilt off the motor housing. Now, locate the 9/16" plastic cap nut in the middle of the fan and remove it with a socket wrench. You'll need to pry the fan free from the motor shaft. Save the washer under the fan. NOW, you can reverse the order to re-assemble the unit with a new fan. Good luck, and don't trust everything you read on the internet!
