Two 500 KVA units down within a week Dirty load

[petersonra]

well i would maybe consider the 5000 hour unit as a bearing issue the axil measurement on the fly wheel was around 2mm so in theory it seems excessive
The other unit 3000 hours is a 2005 unit which the bearing unit looks and feels perfect with no movement and .5mm axil movement on the Engine flywheel
ATM its a bit of a fight with manufactures to get any answers about there product or any support

It is often hard to get tech support on old units since many times the only guys who knew much about them are gone.
