CD 28 Stuffing Box

Post by BGS »

I know this has been discussed extensively in the past but I am not sure what else I can do.

I cannot get any wrench on the lock nut because access is so tight. This is not the typical stuffing box that most other CD's have. It seems most have the Spartan kind that has some teeth in it almost like a gear but not the CD 28

I have tried:

-Lock nut wrenches cut with angle grinder. They cannot be cut small enough. One snapped because it was cut too thin.
-strap wrench... I got the strap around it but didn't have any room to move the handle
-screwdriver and hammer... That didn't last long because I was just stripping it.
-lots of pb blaster... But that hasn't really mattered yet because I haven't been able to get a good turn on it yet.

My next plan was to buy some flat bar and have someone cut a custom wrench for me but that doesn't seem too easy either because it will probably take a few tries to get the wrench to the correct size

Anyone know another type of wrench that is not adjustable that could be cut by an angle grinder? Or have any other ideas? Or am I on the right track with the custom steel flat bar wrench?

Thanks!

I don't have a good suggestion, but to be honest I don't like the way the threads look on the stern tube set-up. Have you considered having the whole apparatus replaced?

One hint -- The bilge angle / confines looks very similar to that of the Pearson Triton -- you may be able to find a solution from Triton owners as well.

You might be able to find one of these in the correct size, or modify a box end wrench to fit. These get a better grip than open end wrench, so maybe you could grind it a little thinner.

This may be way more work than worth, but I will present it anyway.

If you disconnect the coupling between the shaft and transmission, then, from outside the boat, work the shaft out either partly or all the way, you might be able to get a socket over the nut and use a ratchet. It will be a lot of work, particularly if the shaft is corroded or has any burrs so you might take some emory cloth to it first.

I agree this looks very different than the usual Spartan set up, and the stainless shaft hints at an aftermarket change since I think the original shaft was bronze. (At least mine is).

PB blaster is not going to work on bronze. If you can find away to soak it in vinegar, this will clean the bronze.

PS: you must also have two wrenches. Use both at the same time. Position the handles so that you squeeze the two w/o applying torque to the tube. But, it looks pretty jazzed up. Unfortunate, Cape Dory really mucked up this area. Cutting it out and rebuilding may be the long term solution. http://www.capedory.org/board/viewtopic.php?f=9&t=33228

Had a similar problem last year on my CD 28, after struggling solo for a number of days I enlisted the help of a friend. Using pb blaster, channel lock pliers, and a butane torch we go it loose within minutes. The hardest part is figuring out how to position the two pairs of channel locks in such a confined space.

Are we sure about that :?: I think I used PB Blaster on a Spartan bronze seacock. It took a few days of spraying the seacock and waiting but it did work. I had tried others - WD40 and Liquid Wrench. They did not seem to work. Of course, it could have been a delayed reaction to the WD40, plus the Liquid Wrench plus the PB Blaster. :D

With regard to PB Blaster--the stuff is absolutely positively amazingly effective on rusted connectors--I offer two observations. First PB Blaster needs a bit of time to penetrate the crud, sometimes days. Second DO NOT let PB Blaster contact engine seals as it can ruin them. Be watchful of the transmission's rear seal if spraying along the shaft/stuffing box.

The scent of PB Blaster is not IMHO an acquired taste. Ventilation is good for you!
