Re: Hurth Gearbox

Jim Anderson

On SM 384 equipped with the Yanmar 4JH3HTE, for preventative maintenance I recently removed and had rebuilt the 5 sea water cooled heat exchangers: engine heat exchanger, engine oil cooler, engine turbo inter-cooler, generator heat exchanger, and the Hurth reduction gear cooler. Along the sea water supply hose that goes to the Hurth cooler there is a yellow and green bonding wire. I forget where it is supposed to go.It's length appeears to end at about the end of the little heat exchanger and the wire is stripped for a short section about 5" before it ends. Does anyone happen to recall where and/or how the bonding wire is attached?  (Photo posted in Photos section. Thanks,
