Hey guys, I was GIVEN a Biax 8E flaker in pretty rough condition (box badly rusted), but with all blades and in almost working order. I say almost because it's all there, but the motor wouldn't run.
After a serious few hours of fighting, tapping, strap wrenches, pipe wrenches and various combinations of curse words, I finally got the knurled chrome ring off and separated the motor from the gearbox. Motor was bound up from a combination of rust between the rotor and stator and probably solidified grease in the rear bearing (one in gearbox end is free and smooth).
I managed to get it to turn by working back and forth and then blew out the windings and rotor/stator gap with air. The motor will now run, but it sounds like a rock crusher and you can feel the clicking in the shaft when you turn it by hand. I have only run it for a couple of short bursts to prevent burning up the windings.
The brush plugs are so stuck I can't get them out, either. Screwdriver just smears the plastic without removing. Again, stopped before I totally destroyed the slots. I have not found a breakdown on line and figure parts are not available, anyway.
I have a motor shop in the same building as me, so have access to whatever bearings I might need... IF... I can get the rotor out. I have brushes in the box, so can replace those, as well as cleaning up the armature and slots.
