850 XL Motor w/ gasket and orange brushes. Part #819T, not the same as the smaller #886 motor with green brushes, please ensure part numbers and brush color match before ordering, the 850 dryer can come with either motor size depending on what version you purchased.
(This motor is exactly the same as the 923 motor from Electric Cleaner, but this one comes with tapped holes for mounting inside of a Double K dryer. The 923 motor from Electric Cleaner is not tapped for mounting, and you will need to thread it if you try to use it instead.)
