Yorkville horn driver replacement help
« on: October 08, 2011, 10:40:49 am »

Specifically NX25P.
I purchased replacement diaphrams, but not sure if the the driver twists off or if the assembly has to be removed by the 4 screws on the plate that the driver appears to be attached to.  Don't want to do damage or remove anything unnecessarily.  Any other tips or tricks work be great.

Thanks,
David

Plate is part of the assembly.  Driver bolts from opposite side.

*********************
When I cleaned the gap there was a brown oily substance, parts the constistancy of 3 in 1 oil, and parts that are like goo in the bottom of a coffee pot.  There was some on the former also, but only noticably visible in one spot.  It took 5 or so cleanings with tape and then TP on card stock to get the gap clear of this substance.  Is it a lube of some kind that needs to be there?
One more to do.  Wonder what I'll find.

That was probably ferro fluid.  Without it the parameters of the driver (including power handling) will be different.

I highly suggest replacing it.  Contact Yorkville first before using a generac fluid.

The goo that I got out was chocolate brown.  Isn't ferrofluid Black?  And reacts to magnets?  This stuff seems inert.
