Gabe - For model number DWS779
November 30, 2022
How do you remove the pulley on armature? It does not appear to be keyed. Does it unscrew? Thanks!
Chris Boyle Profile
Hello Gabe, Thank you for the question. Try adding heat with a torch or heat gun and use a gear puller to pull it off. You might be able to just use a gear puller. I hope this helps and good luck with your repair.
