Motor Housing 5140011-81

Removed motor from the planer, which requires removal of drive chains, cooling shroud and the drive pulley. Considerable disassembly of the planer body is required for access. The motor was opened and taken to a guy who rebuilds starters, generators, alternators, etc. and he replaced the bearings using a press. He didn\'t charge much f ... Read more or this, and probably most people will have trouble finding someone to replace the bearings for them. However, when the motor was reassembled it still didn\'t rotate, and at that point I discovered the housing had melted. So I had to disassemble it again, remove the windings, put it all back together. At this point I should have checked t see I had the directional right, but I didn\'t, so when I had it all back together discovered it was running backwards. *sigh*. Removed everything, reassembled it again, but one of the mounting screws was stripped out at this point so had to use a lag screw there. When installing the drive belt, you need to be able to R & R the cutter head, which requires grinding down an open end wrench to fit in there. Then to install the pulley requires a LOT of force, which I eventually discovered after an internet search. I assumed there was some trick to do it, but no, it just take about 50 foot-pounds on a breaker bar. But once that was done, it now runs, but it is developing more heat than seems right. There may have been some damage to the armature when the old housing melted. But the replacement part worked fine and was inexpensive--bizarrely, it was cheaper than a replacement drive belt! This is not a job for the faint of heart. I could do it much faster now that I\'ve made all the mistakes. Unfortunately there isn\'t anything on YouTube to help you, and since I didn\'t video it, I can\'t post. Be advised that if you blow the pulley-end armature bearing you\'ll need the housing because it gets hot and destroys the housing. If the other bearing goes out you won\'t need to do all this because the cooling fan/shroud there keep the temperature under control, but the pulley-end bearing is the one under stress and most likely to fail. Suggest replacing these bearings preventive if you have to replace the drive belt or cutter head.
