Re: (ET) More on my leaf sucking blower problems



Steve:

I have no experience with the blower, but your measurements suggest (to me anyway) that maybe the fan itself has bent fins?  Can you figure out a way to check the balance of the blower wheel and determine if all the parts are more-or-less straight?

Hi again GE tractor folks,

Before I spend a lot of time trying to straighten and balance my leaf sucking blower's blower wheel I thought I'd ask...

Does anyone have a surplus blower wheel they'd like to part with?

It might be cheaper in the end to replace than fix.

More on my motor.  My motor, as best as I was able to measure with it's roughened shaft, has 0.0035 to 0.0040 inch runout.  My GE dealer service manual states that 0.004 inch is OK for our motors.  I think the 0.0015 inch is more appropriate, but maybe 0.004 inch is OK for motors used intermittently like the motors on our GE tractors.

I did reassemble the motor but left the blower wheel off, and it does not vibrate, which is good.  It does make excessive noise.  I'm now pretty sure that the big end bearing has a dented bearing race.  I couldn't feel any issues when I checked by hand, but at full speed it's too noisy.  New bearings are in it's future, but maybe not until next season.

So if you have a blower wheel or even an entire blower let me know.

Thanks folks,

Steve Naugler
