Hi, this might be the wrong forum, but we urgently need some help with our shaft seal
. We have a maincraft deep sea seal, which has just been serviced while we had our shaft out and a new cutlass bearing fited. We asked for it to be replaced but the engineers said it was still fine.
It has always leaked to a degree, worse with higher engine
revs. Now it gushes when underway, even at very low revs. The engineers have all left for the Christmas
break and are shut all next week. I've searched online but nothing I've come across has any info on the water
feed. We have tried adjusting the seal faces etc, but are convinced that it has something to do with the water
feed (too much pressure) because it drips constantly when there is no motor
running. Does anyone have the manual for installing a manecraft deep sea seal that they wouldnt mid scanning, or know if the seal for slow speeds (e.g under 1200 rpm) needs to have additional water injection.
Thanks so much for any help with this
