Replaced all drum rollers and lint fan which was packed with lint. Replacement rollers did not have same nut size so had to keep switching sockets. Needed adjustable wrench to fit behind fan motor to get nut off. New lint fan was not a tight fit on shaft so hopefully loctite will hold. Did not want to remove rear panel to replace rear rollers so used wrench behind panel to hold the nuts. Cannot use gloves in these tight sheet metal spaces so be careful of the cuts.
