I wanted the transport axles off my Toro GM1000 so I could get closer to objects.
This is a spare GM1000 that I have and I had so much trouble getting them off the first one, I dreaded doing it again on this one. It turns out, I was fortunate this time. They came off without much trouble.
Toro puts thread locker on the axles to keep them in very tight. The best way I've found to remove them when they have thread locker applied, is to heat up the axle with a blow torch for three minutes. This gets it hot enough to loosen the thread locker and allow it to break free. My first GM1000 required 3-4 minutes of heat from a
Berzomatic, locking the inner axle with a 1 inch crescent, and then hopping on the crescent on the transport axle. It was a nightmare up until that point, but the heat made it work nicely.
Today with this one, I put the 1 inch crescent on the inner axle, put another crescent on the transport axle, stood on it, and:
pop!
If you want to take yours off, first try the easy two-crescent method. If that doesn't work, buy a torch, take your belts off the pulley's and heat it up.
