For all of you doing the upper pulley mod, does pulling the pulley off result in any damage to the nose of the blower? I had a 2000 Lightning but I went with the lower pulley because I read that the upper can cause damage to the bearings/snout. I never considered the upper after that, until just now when I came home with my cobra
This is the lightning's article:
"Unlike ALL other Eaton blowers that use a keywayed blower shaft, the Eaton M112 used on the Lightning has a PRESSED on blower pulley, not a slip on pulley held in place with a keyway. Using a puller to remove and install the upper pulley can damage the blower snout, and many owners have already had to purchase new blower snouts because of this. Because of this exact problem, some shops will remove the blower snout and remove and install the aftermarket upper pulley with a press, but this also is not a good idea. According to both Eaton and Magnuson (the only Eaton authorized remanufacturer), to press the pulley on and off an M112 snout, requires a special tool that fits inside the snout, and supports the shaft bearing from within. This is the only proper way to remove and replace an M112 pulley, and unfortunately only Eaton and Magnuson have this tool. Using a shop press to do the pulley swap works, but will still damage the shaft bearing and cause premature snout failure down the line. "
Thanks for the input/help guys! :rolling:
