How do I remove the generator from the engine on a LR 4400 Homelite?

Here is a copy of the owners manual and it has an exploded diagram that you can follow to remove the generator part. When you take off the back mount and then you will see inside a coil that rotates, this is the rotor, and a coil that is stationary around the rotor, this is the stator. Make sure that you take good photos and mark all wires that you disconnect, this helps in re-assembly later. To remove the back support called the brush head, you need to remove 4 long bolts and one in the center that holds the rotor to the engine. Gently tap the brush head away from the stator with a small hammer. You might need a small blade screwdriver to pry, remember GENTLE is the word here. Now, you might have to block up the stator so that it is supported since the brush head is removed. The stator might need some gentle prying to remove it from the engine. When pulling the stator off, be careful that you do not drag it on the rotor, this might damage the rotor. With the long bolt that held the rotor to the engine, screw it in and leave about 1/8" of it out so that the head does not make contact with the rotor shaft. Now with a small hammer, strike the head of the bolt while at the same time pulling on the rotor towards the head of the bolt. The rotor should come loose and you remove the bolt and pull the rotor off gently. To install, you never need to use the hammer to mount the parts.
