Generator fan interference

 
Threaded View
My friend replaced a generator (dog house) and then had a terrible
howling, scream. esp. as the RPM's picked up.
he claimed it made no such rubbing noise when hand spun during
installation.
Q is  what can this be and the fix?

Hasnt sucked something INTO the fan assembly?. Spinning by hand it wouldnt
make a noise but at RPM would. The sound insulation on firewall? May be
bearing noise but I,ve never heard one that loud.

Have your friend loosen the genertor strap and first look at the belt
to make sure its in line with the crank pully, you can push or pull on
the dog house to adjust this.  move it a little ans then see if the
fan is rubbing the dog house ...He might have to add a shim.

O/P
We took it apart and found some dents in the air shroud housing , some
high spots were getting mighty shiny. the old pall peen hammer dispatched
them.
It's just fine, now.
Thanks, for the suggestions.

My only advice: listen to nothing kafertoys has to say. He believes
bondo and financial thievery is the solution to every situation.  Your
mileage may vary.

Re: Generator fan interference

I agree with bugnut.  So i'll recommend it.

I have had one that would rub the fan on the shoud.  It sounded as
described.  I'd check the fan.
