[C320-list] Port side gate stanchion replacement

[Onat Dogruer]

I think there has been some good write up on this topic on Mainsheet and I remember seeing someone on the group posting up as well.
I replaced port side gate and port side midship stanchions at the beginning of this season on our 1998. They were bent significantly and didn't want to straighten them as, apparently, the process weakens stainless steel.

In addition to the previously noted points, a few observations I would make:
-I had to take the cabinet off in the galley above the stove.  The liner is 1/4 inch thick and there are wires behind it. I placed a small steel plate behind not to chew through the wires with the hole saw bit.
-There are 1/4" bolts (5/16" washers); the ones on the front are 2.5 inches in length, in the back are 1.5 inches( h shaped).  I replaced all with new stainless steel bolts.  Don't try to salvage bolts; worth replacing with slightly longer ones.  As Warren described below, the washers that came out were cup-shaped because of the pressure over time.  There was no backing plate.

-I used 1/4" G10 fiberglass board as backing plate; because of the contour of the underside, I used a little bit fairing compound to fill depressed areas so that the plates press firmly underside.  Longer bolts are needed to allow for the backing plate. (Made 3 pieces for the gate stanchion - one piece for the large bolt, one piece for the 2 bolts in the back, one piece for the 2 bolts in the front)

-Chamfered/countersunk the holes from above to allow for butyl tape

-Used crow-foot set and 4" ratchet extension bar, a ratchet angle extension underside to handle weird turns

-Total labor: 12 hours (for both the gate and midship) if you have all the parts you need

Hope this helps.

Working with the stanchions is one of the more frustrating jobs I've done. I've done most of it; but, used our yard staff for the port gate stanchion. They cut a slot out of the "molded in cover" to facilitate the re-installation of the stanchion. This is not a problem (for me.)
Here is a trick I've used on other hard to reach areas: use a small dots of butyl rubber to hold the nut and washer assemblies together. Then with the wrench put in place and secure. I'm using butyl rubber for most bedding jobs so had some hanging around. 
The bigger issue is that Catalina used light-weight fender washers with no backing place. In truth, some of the spaces would not allow for a backing plate. The underside of the deck in places, I found was too fragile for the original washers as they were pulled into the deck and were cup-shaped when I removed them. 
Hope this helps someone.

Hi Daryle,  I have not removed/replaced the port side gate stanchion but have done the starboard side.  It was fairly easy to remove but reinstallation was a 2 person job and required a lot of cursing and swearing, glue, tape and some special clothes hanger wire tools to hold the 1/4" washes and nuts to get them manoeuvred and the thread started. The larger 1/2" nut was by comparison easy but not that easy.  There was a fibre glass web on starboard side (maybe the same as what you are encountering that did make it much more difficult.  Cutting it out would have helped but I worried about doing that.  I also had some of the nuts and washers fall and disappear forever, so had to get spares.

Good luck

FWIW

Ken

    Just noticed cracks in the weld and bend in my port side gate stanchion, the one shaped like an "h".  Bought a new one from Cat Direct.  Removed the microwave to access the forward bolts (easy).  The aft bolts are in the cupboard aft of the microwave but there's a molded in cover for the wiring harness that makes it impossible to get to the bolts.  Has anyone run into this problem?  Thought I'd check before cutting a hole in the cover.thanks, DarylDaryl HuntC320 #660 BelieveRochester, NY / Lake Ontario
