I HAVE A GENSET AS ABOVE COUPLED WITH A HONDA GX140

THE RINGS NEED CHANGING BUT I CANNOT FIND SOME ONE WHO KNOWS HOW THE ROTOR IS ATTACHED TO THE HONDA.
I SUSPECT IT IS THREADED ON BUT AM ASKING THE QUESTION BEFORE THE HEAVY MOB MOVE IN. THE UNIT IS ABOUT 12 YEARS OLD AND I HAD THE STATOR REWOUND FOR HEAVY USE ABOUT 8 YEARS AGO SO AM KEEN TO KEEP THE GEN GOING EVEN IF THE MOTOR IS REPLACED. IF ANY ONE HAS SOME ADVICE IT WOULD BE APPRECIATED.

CHEERS CHRIS

Chris.
Is the caps lock button broken on your key board?
Some of the dunlites have a holow shaft in the armature with a long bolt into the end of the crank. Eric.

Pity those in who do know cannot read it.
If you can post using the Internet you could be well mannered enough not to shout at others when seeking assistance.

Chris. When you take the alternator end cover off I think you will find an about 1/4" hex stud. Unscrew this,it goes right through the armature and into the end of the crankshaft. The armature is held onto the crankshaft simply on a longish taper, a good whack with a wooden mallet will release it.
They are not normally on a thread like water pumps.

thanks kesh seems i have a brumby one. with the cover removed ( with the switch plate) there is a bearing on the end of a shaft but no bolts or stubs. i took the bearing off the shaft incase there was a grub screw bored lateraly under it but it is a plain old shaft. i hadn't taken the water pump analogy so if the motor was a pump motor it is posible i guess. i have had 3 small motor mechanics look at it but they all just scratch their head and say buy a new one.

thanks any how regards chris

The motor will be a GX140V with a tapered shaft. There is a stud in the crankshaft which screws into the end of the alternator. You need to be able to lock the flywheel and use a strap wrench to screw off the rotor.
You need the special factory tool to lock the rotor, or use another large strap wrench. DO NOT (used in expression of importance) attempt to jam something in the fins of the flywheel. While any tapered shaft is difficult to get off without the proper tools, the rotors with the bolt up the middle of the rotor and able to unscrew it from the end is preferable.

And thanks from me too, Morgan.
Am always pulling something or another apart, and not encountered that system before.
A little bit more knowledge to store, but thats never a hardship.
cheers the kesh

thanks morgan it was easier than i had imagined. the special factory tool was a oil filter remover and after stuffing a soft rope in the barrel on compresion stroke i got my off sider to hit the end of the shaft with a drift as i applied presure and it spun off no problem.

to the cap locks comment be alittle patient we arn't all up to speed whith the internet, if you hadn't guessed i cannot even type.

thanks for the help

cheers chris
