trane chiller; leaking inlet guide vane bearing asssembly

[oupak]

what are the causes of the leak on inlet guide vane bearing assembly on a centrifugal compressor... that is excluding th chiller surging....

[Lowrider]

wrong adjustment of the stepper motor or assembly can cause the seal to leak too.

And setting the max steps too high too.

as said by lowrider all is correct .
we also found that when replacing the seal check the shaft ,make sure it is not etched or oval .
if this is the case replacing the seal will help for a very short time.

Where is it leaking, through the shaft seal or through the bearing housing face? How old is the chiller?
