Took front door and panel off dryer, much easier to access motor and exhaust blower from there. Although, it takes some getting used to, to "pop" the top lid off those spring clips, then once it's off the molex connector for the dryer switch is a "B" to get apart, and when putting front panel back on make sure to slide the clips into the slot at the bottom of the panel before you put the screws in at the top or the panel will only be secure at the top and the bottom will just float.
That being said, the belt "rubbing" problem was solved by flipping the belt to the other side of the exhaust blower pully. If yours comes off, put it back on the motor pully first, then on the exhaust pully. If it's rubbing, take belt off exhaust blower pully and "flip" it. (Put left side of belt on the right side of pully). It will clear the plastic guide that is on the blower housing.
By the way, when the blower pully came off my machine, I could'nt find it anywhere! So I took the front and back panels off, closed the top section, leaned the machine on one corner and shook it back and forth briskly. still no pully so I leaned the machine on the opposite corner, shook it again and the pully lossened up and popped out. Must have been stuck in the upper part of the machine!!
These pullies are left hand threads also.
