Alex Koh Posted March 19 Share Posted March 19 I'm new to working on these later Century fans. Is there a way to open the gearbox on both of them without destroying the pot metal? Quote Link to comment Share on other sites More sharing options...
Stan Adams Posted March 19 Share Posted March 19 If that rear cap doesn't screw off by hand, then no. I have owned both of those same model fans in the past & both of them turned into basket cases. 1 Quote Link to comment Share on other sites More sharing options...

Alex Koh Posted March 21 Author Share Posted March 21 I'm not too sure where to go from here. I started chipping away at the rubber gasket that in between the cap and tried soaking it in penetrating oil and the cap won't budge. Quote Link to comment Share on other sites More sharing options...
Jim Henderson Posted March 21 Share Posted March 21 The pot metal threads are probably fused and distorted. Quote Link to comment Share on other sites More sharing options...
Alex Koh Posted March 23 Author Share Posted March 23 Sucess. Turns out the rubber trim was the problem, after picking away at it and sitting the back cap in a pool of WD40 it broke loose. The cap is still perfectly intact. Quote Link to comment Share on other sites More sharing options...

Sadly that luck may not work again for the second century. Somebody tried opening it with a tool and damaged the cap a bit. I’ll still give it a try in the future but I’m expecting it to fall apart.

Steve Stephens Posted March 23 Share Posted March 23 I avoid the Centurys except for the 5-speed models that are all cast iron and steel without the usual decomposing pot metal parts. Sometimes you'll come across a pot metal 3 speed century that is in good condition. Check to see that you can remove the rear gearbox cap before buying and look closely for any cracks in the pot metal. Quote Link to comment Share on other sites More sharing options...

Alex Koh Posted March 24 Author Share Posted March 24 For some reason I can casually move the front bearing back and fourth withA some force. But it doesn’t ever slide out of the housing. Quote Link to comment Share on other sites More sharing options...
Alex Koh Posted Tuesday at 10:38 PM Author Share Posted Tuesday at 10:38 PM Who would’ve thought that the two nails for the tag actually held the stator in. Explains why I was unable to remove the stator. Quote Link to comment Share on other sites More sharing options...
Paul Carmody Posted Wednesday at 12:57 AM Share Posted Wednesday at 12:57 AM Thanks for showing the screws in the stator.That could be useful information in the future for myself and others. Quote Link to comment Share on other sites More sharing options...
