Hi, new member here. I recently received an old buck stove (27000). The motor makes a loud racket when it is turned on. So, I plan on getting it repaired/replaced. However, I am having difficulty getting the fan removed. I have removed the small allen bit portion, but the darn thing won't come off. I've sprayed it with wd40 and pbblaster with no luck. Can anyone give me tips on how to remove this thing? Thanks in advance ..
