Extending clutch bank

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi everybody,

On my 350 the starboard clutch bank consists of five Spinlock XAS clutches, a triple and a double, while the port bank has two doubles. The mounting pads are both the same size, which leaves the space for an additional clutch on the port side.
I have read elsewhere on this forum that the clutches are mounted with machine screws into a pre installed plate set into the coachroof . I would like to extend the port bank to take a reefing line for the third reef, does anybody know if the plate on the port side is large enough to take the 5 clutches, and how easy it is to locate and drill through to presumably replace the existing double with a triple?

Many thanks

Bob

	This is correct. I've done this upgrade on my H355 (deck layout is 95% the same). I put a new clutch for cunningham. Simply unscrew the present 2 way clutch. Put the 3 way in place and screw it. Mark the 2 new holes (for the 'third clutch'. Unscrew the clutch. Drill carefully to 5,5 mm (take care of axis ; be perpendicular from deck level). Tap aluminium plate to 6 mm (very easy with good quality tools). Screw the whole thing back using TefGel or Duralac + a drop of sika & it's done. It's maximum a one hour job. Just need the right & efficient tools + care & precision .

	Hi Bruno, Thanks very much for the clear and detailed instructions, I will get a good tool to tap the thread and hope I find it as easy as you did. Bob
