Re: Onan ballbearing check and valves values

Oliver Henrichsen, SV Vela Nautica

Hello and thanks 4 your answers.

But the question was:

Is there a procedure to check the generator bearings for wear? As mentioned in the manual / service plan?

Sorry, guys. I did exactly the same thing as Gary Silver, and the bearing was never installed.

Hi Gary,
It's been awhile, but I replaced the rotor bearing on my Northern Lights 6kw genset in situ with little difficulty. The rotor remains bolted to the flywheel as you remove the end with the bearing - no external support needed. I recall I did the old put-it-in-the-freezer trick to shrink the bearing and it slid in with no press needed.  That was at about 3000 hours; now I'm at 7500 and am overdue, so will tackle again soon. (I'm getting a very slight vibration with heavy loads.)
If you want to remove the rotor, as I did because it needed rewinding from salt water corrosion shorting the wires ($176 in La Paz VZ), it's heavy but quite manageable by hand. However it doesn't sound like you'd need to remove it for the 2500 hr. (if I recall correctly) bearing replacement..
Cheers, Craig
