Replacing Chain Plates

Tip Thienes

I have to change both port and stbd aft chain plates. Any tips on getting the top bolt off? Long spanner is only thing I can think of. There is not enough room for a ratchet. Putting new chain plates on will be, "character building" to say the least. Any one ever done this. Not to mention removal of teak strip that fits over one bolt. Appreciate any comments/help or ideas. Certainly someone out there has changed all the chain plates , help please

If you use a fine blade saw, and cut the rubrail on each side of each chainplate, you can remove that piece of teak. Use masking tape on the hull to prevent scratching it. After replacing the chainplate, put the piece back using some brown caulking, and the job looks neat.
It is difficult to reach up inside the bulwarks to get to the nuts. You can use one of the ratchet wrenches that have the nut holder within the wrench, and the bolt goes through it. Don't know what they are called, but you should be able to find a 9/16" one at any good hardware store.

if the other four chainplates are original I would suggest changing them out as well. I changed out all six of mine and found four of them had cracks which could not be seen from the front of the chainplate.

Alternately you can use a hole saw and cut a large plug out, loosen the bolt and push it out through the hole. Then cut a larger plug out of teak and glue it back in. Sand, oil and no one will be able to tell what you did.

I would grind the outside head off the bolt and push it thru.

Seems like it will be easier to get the new one in. The old one will be hard to get out with all that 30 year old goo on it.

Bolts are cheap.


Bud Taplin

Rich is right about grinding off the head of the old bolts. I always supply new bolts when I sell chainplates.

Here is a question for Bud or anyone else. I recently bought a 1978 W28 which has been on the hard for the last 9-10 years. Should I remove and inspect all of the chainplates? Most, of not all, of the nuts appear to be accessible from inside. I want to prepare the boat right, but not looking for unnecessary work.

Jim Focha and Julie Gwin

We replaced our chain plates last year. Some bolts were actually in the bulk head and glassed over and the top bolts were almost impossible to get. A rachet box end would not go over the bolt so we bought an extra long open end wrench and Julie was able to get to them. We found removing the rub rail was not a poroblem.

George, I would recommend removing one chainplate, and checking the backside. If it still appears to be good as new, then don't bother removing any more. However, if it does have some crevice corrosion, then it would probably be best to remove more of the chainplates to be sure of their condition.
