Blower motor running and heating. Decrease in air circulation.

Using a blowup of the appliance, I removed the two screws that hold the front on and removed. Using the correct sized socket, I removed the housing that holds the front of the dryer drum in place and disconnected the wire to it. I then removed a shield near the blower unit and unbolted the front of the blower assembly. I could not get my power drill into position to take off the very bottom bolt but found that it would pivot forward enough to gain access to the blower fan. I then busted a knuckle trying to get the keeper washer off of the shaft (don't have a C ring tool). With some cussing and another scrapped knuckle, I took off the keeper ring and removed the fan, replaced with new fan and ring, broke the C ring trying to replace it so just left it off. I then went to cleanse wounds and apply dressings.
