Does anyone out there know of a NEW dry cone cluth being manufactured? I recall seeing these many years ago and wondered if anyone was making them today.
Thanks for your help.

I don't know anyone making them now but some time back I put a photograph on here showing one. Perhaps someone with a better memory than mine will remember and know how to find the photos
Bottom line is is this what you are talking about? |

Mark - there are a number of folks still making dry cone clutches. Do a search on Thomas Register or look at this url
http://theduchy.ualr.edu/classes/asci5335/clutches.pdf
where you will find some basic info. |

Recently I had to pull a part the cone clutch on my "Donk" (that's its brand - 4.5 HP single cylinder 2-stroke - an Australian made motor that featured in Australian Amateur Boat Builder a few years ago). The clutch wasn't disengaging properly - I eventually found a grub screw had come adrift.
Anyway, my question is, other than greasing the shaft do these clutched run completely dry - unlubricated? The face of the clutch assembly has a small plug that looks like it is positioned to add lubriaction - I can't think of another reason for it being there?
Any help / advice will be gratefully accepted.

Yes............ in answer to your question Michael. They are either in or out . No need for any lubrication , only on the throw out mechanism.But i will stand corrected if need be ! |

Regarding cone clutches that run dry, does anyone know what included angle is best for the cone / cone friction face - to transmit upto 3 HP? As these are difficult to come by, I was thinking of making one out of mild steel on a lathe (ie approx 3 inches outside diameter x 3 inches long - I was thinking of using an included angle of 30 degrees between faces). I will post the outcome of how successful the clutch is - with pictures - for others to view. |

This is a 1912 ad, I put a navigation protractor over the original ad and it looks to be very close to 30 degrees !

Hi Richard,
Many thanks for your message about tne angles of dry cone clutches. I did a bit of research on this and the following web site shows how to design them -/www.roymech.co.uk/Useful_Tables/Drive/Cone_Clutch.html
- the included angle across a profile of the cone faces should be around 24 to 30 degrees according to this article, to prevent jamming, and get enough grip. Will post the results of my construction when finished. Many, many thanks! |

I am desperately trying to locate a cone clutch and operating levers to match up to my 6hp Norman Inboard. Does anyone in NZ have one that they would sell? |
