You can beat on the rotor laminations with a rubber deadblow hammer...hitting it a couple of times then spinning it and hitting it from the other side. Make sure you are not hitting the windings, slip rings, etc... only the laminations. You will not hurt the rotor this way.

What do you mean (rotor), if you mean the flywheel. The shaft is tapered with a key-way. Really a puller is used. You can try using a brass punch to loosen or break it loose but be careful. If your talking about something else just let me know, hope that helps.

How do I pull the motor from the generator assembly?

You have to put a wrench on the rotor where it sticks out of the bell housing and another wrench on the flywheel with a tool that miller makes to bolt onto the flywheel. Break it loose and then pull the engine and rotor as one piece off the welder. Then unscrew the rotor the rest of the way and remove it.

How to remove and replace the stator from a champion generator

You don't state what model you have. I just replaced the rotor on a Champion Model 41302 but removing the stator is the same process.

You will need to remove the muffler and muffler outer protection. Remove the bolts that hold the muffler outer protection. Remove the two bolts that hold muffler to the engine exhaust.

Take a block of wood and place it under the engine to support the generator. The supports on the generator head end will be removed so the generator will tip down and make it difficult to remove the stator.

Remove the generator end cover by removing two bolts.

Remove the two bolts that hold the muffler to the end cover.0834b898-460f-41f6-b0a0-6704ae605277.jpg

Remove the bolt that holds the ground from the generator to the frame.


Remove the two bolts that hold the end cover supports to the rubber supports to the frame.



Disconnect the quick connect electrical connectors and remove the 120/240 volt wiring from the terminal block. See second picture below.



Remove the ground from generator to wiring cable assembly by removing the bolt that connects it to the end cover. Yellow and green wire in picture above.

Remove the bolt from DC brush assembly and pull out of generator. Picture below shows assembly removed.


The stator and cover now can be removed from the generator. Take a rubber mallet to tap on the back of the brackets on the end cover to loosen it. The rotor bearing is seated in the end cover making it hard to remove by pulling by hand. Once lose pull straight out.

The stator can now be removed from the generator end by taking the four bolts out.

The installation process is the reverse.

Take the through bolt out of the end of the alternator / rotor shaft. it is a long bolt. The shaft from the engine is tapered and unlikely to just pop off. Find a bolt that will screw into the end of the rotor shaft (hardend) find a metal bar that will slide into the rotor long enough so the bolt tightens down on the bar, it will pop the alternator off the tapered shaft

How do i separate the engine from generator on powermate 5000

It generally has a long rotor through bolt accessibile from the generator end, this forces the generator rotor onto a tapered shaft on the engine. Once removed the through bolt slide a long bar ion the hole and screw the bolt back in, that will force it off the taper

Rotor won't turn due to rare earth magnets have to much magnetism. The generator was working fine and the bearings had to be replaced. After replacing bearings and reassembling the generator we were...

You do not say what type/model generator you have, so I will just give you some basics.

There is nothing wrong with the magnets. Their power did not change at all, their pwer never changes, except to degrade slightly over time (hundreds of years.)

The generator rotor is hitting the stator. In other words, the alignment of the rotor inside the generator is off center, making the rotor bind on the inside of the stator, resulting in a lock-up.

With the generator attached to the motor, remove the generator end, and slowly try to turn the engine over by hand. REMOVE THE PLUG WIRE FROM THE PLUG FIRST, so that the engine cannot start. Watch inside the generator, and discover why the generator rotor is not aligned. Pehaps the bearings were installed incorrectly, or the housing is installed incorrectly. Most generator engines have a tapered power-takeoff shaft, where the gen. shaft connects to it. Is this Bolt tightened to specifications? Is there some debris floating around in the gen. (such as a screw, or a pebble, or a nut) that would impede its movement?

good luck

How to remove generator from engine (model DGUH5S-2). 11 horsepower Honda engine.GX340 .

I have not worked on Dunlite generators, however have worked on many different brands using the GX340. When removing generator parts, one must keep in mind the brushes contacting the armature. Remove brush pack if any and set to side. Next unplug stator wiring making sure to draw diagram of connections. Remove bolts mounting generator/stator housing to frame and carefuflly pull off leaving only armature /rotor on the crank of the engine. Remove the long bolt thru rotor into crank. Now you will need to apply penetrating oil to the shaft of the engine to loosen the rust on the taper. It may take several applications. Place a piece of hardwood against
metal to protect the rotor and firmly rap with hammer on
both sides. You may need to use pry bar against engine
and rotor as you hammer hardwood. Repeat as necessary,
some rotors will be very stuck due to rust. Be very
carefull with hammer and or prybars not to damage
windings. Have patience and let oil work. Good luck.

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.

Disconneting generator from motor. PM54A4302 Coleman generator. I do not know how to disconnect the generator from the motor, I would like to know how to release the motor from the generator.

I am assuming that you have removed the end bell with field winding (long bolts that extend from outside of generator into mount bolted to engine) and the only obstacle is the rotor on the crank of the engine. I am also assuming that you were able to remove the long bolt thru rotor into crank. Now you will need to apply penetrating oil to the shaft of the engine to loosen the rust on the taper (tapered shaft fits very tightly into core of rotor). It may take several applications. Place a piece of hardwood against metal to protect the rotor and firmly rap with hammer on both sides. You may need to use pry bar against engine and rotor as you hammer hardwood. Repeat as necessary, some rotors will be very stuck due to rust. Good luck.

How does the generator come away from the engine? regards dan

Most of these one removes the field and then a bolt is inserted in the end of the shaft and a slide hammer is used to pull the rotor loose. There is usually a Woodruff key to the engine shaft.

How do you seperate the engine from generator.

Assuming that you intend to someday put it back together, do this:

1 - Make it safe by taking the wire off the spark plug and getting all of the gas out of the tank.

2 - Remove the stator part of the generator. There are 4 long bolts with 7/16 inch heads that hold it onto the adapter plate at the engine end of things and a 1/2 incher holding the end away from the engine down on the frame. Some generators have more than 1 frame mount, these are harder to get out, I use a channel lock pliers to hold the rubber mount and a socket to remove the nylock nut. When it's all loose, pull the molex plug out of the distribution panel (where the outlets are) and then gently slip the stator off of the rotor. Try not to break the windings.

3 - Support the engine/rotor assembly by placing a block of wood, stone, or metal under the rear of the engine.

4 - Take the long bolt out of the end of the rotor. Use a 6 point socket for this so as not to mess up the bolt head. This is also much easier with an air ratchet. The rotor shaft has an "innie" cone shape milled into it and the engine has a corresponding "outie" bevel that fits inside the rotor shaft. This is called a tapered shaft mounting. You can get the rotor off of the engine shaft one of 2 ways...
The "official" method:
Get the kit from Briggs and Stratton, tap threads into the inner surface of the bolt hole, insert the appropriate threaded rod and torque it to pull the rotor free. This only takes one tech.

The "redneck" metohd:
You need a friend you trust to swing a hammer, a fairly heavy hammer (I use an 8 lb sledge), and a chunk of 4 X 4 wood long enough to act as a punch when placed against the rotor laminations. Turn the rotor so that the laminations are horizontal. Put the 4 X 4 against them as far away from the engine as you can without breaking the plastic parts of the rotor. While holding the 4 X 4 tightly against the rotor, have the other guy whack the other end of the 4 X 4 sharply and with a good amount of force. Then rotate the rotor 180 degrees and whack the heck out of the other side. Repeat this process until the rotor pops off of the enigne shaft.
My old shop mate and I got good enough at this to take the rotor off in 2 whacks every time.
