GTech Multi ATF replacement fan

The fan blades on my GTech Multi ATF001 cracked and chipped making the motor run with a lot of noise and vibration.
This replacement fan blade will fit in place of the original and the Multi now runs smooth and quiet again.
To install the new fan, remove the old one and then heat the motor shaft/brass collar with a soldering iron. Then press on the new fan blades and make sure that the disk is flat.
