[C320-list] FW: Re: Packing size

[Karl Mielenhausen _/)]

The manual for my 2000, hull 690, indicated 3 rings of 3/16" packing (Ref pg. 45, drawing undated), but I noticed that the newer manual calls for 2 rings of 1/4" packing (Ref Pg. 46, drawing revised 4/2/2002). So, I had both sizes ready when I hauled last week.

Turns out the 1/4" worked fine even though I was skeptical about only having 2 rings in there. I dug out 3 rings of what I suspect was 3/16" flax packing and I used the Gore-Tex GFO packing as the replacement. After about a 3 hr run-in period, it is virtually drip free and the gland assembly remains cool to the touch.

If you can fit 1/4" into your stuffing box then that is likely the correct size for your stuffing box.  There is a lot of circumstantial evidence on this list that even though the manual talks about 3 rings of 3/16" it isn't correct for many folks.  I know it wasn't correct for me.  But 'n' years back I believed it and did put in 3 rings of 3/16".  When I removed it to replace with GFO a few years ago, the cross section of the rings I was removing was now rectangular rather than square.  The long dimension was 1/4" and the short dimension was quite a bit less than 3/16".   -bill----- Original Message ----From: "jsever1 at cox.net" <jsever1 at cox.net>To: C320-List <c320-list at catalina320.com>Cc: Warren Updike <wupdike at hotmail.com>Sent: Friday, February 23, 2007 2:29:42 PMSubject: Re: [C320-list] ?

I made a bent hook tool to pick out the pieces; but, to really get it started I had to screw a long 3" deck screw (they have really large pitch threads) into the packing and pull with pliers.  This started the process and the hook was then able to catch and remove the material.  I keep the hook and screw with spare packing in a zip-lock bag.  Several people at our marina have since borrowed it to replace their packing.>     Having said this and having 
tightened the packing nut several times last season, I'm going to attempt to add another ring of GFO, to the existing packing.  Now that last years new packing has had time to "work in" another ring is called for.> > Warren & Pattie Updike> C320, #62, 1994, "Warr De Mar"> Frog Mortar Creek, Middle River> Chesapeake Bay ____________________________________________________________________________________Have a burning question?
