Hi I have a Breckwell I23 which I bought used. It works good but has a loud groaning sound sometimes from the augur. I replaced the motor with one from Amazon and it was fine for 2 months then the noise came back. I took the motor and augur out. The augur seems good but the bottom edge is a little sharp. The bottom bushing doesn’t seem too loose and the top one is hard to tell. I want to remove the top bushing so I can check the clearance. Do I remove the bushing and plate by tapping up from the bottom? Any advice would be appreciated.
