Compass Reinstall

I took my Ritchie binnacle compass off the boat a while ago to fix a leak. I think the problem was a bad o-ring. Refilled with odorless mineral spirits using a clean west systems syringe. No bubble since!

Now it's time to reinstall the compass. It has a light on it, but it was never wired to the boat. I ran some twisted-pair wire up the binnacle and prepared to reinstall.

Now I'm stuck. I wish I'd taken a picture before removing the compass from the boat.

The ring around the dome has limited options for mounting the light, but they seem to be on the wrong side of the compass.

The compass has six lubber lines: One is yellow and hooked 90. I assume this one goes forward. The are are two other yellow lubber lines 45 to either side of the hooked one. There's one every 90 from the hooked one.

If the hooked one is forward, the light mounts between me and the compass. That's not right.

Did I install the compass backwards? Did someone service it before and flip it around internally?

Re: Compass Reinstall

I'm pointing at the threaded holes for mounting the light:

Re: Compass Reinstall

That looks like it might be a Ritchie Navigator? You have it oriented correctly but the bezel seems to be 180 deg. off. I'm not sure!, But I think that in order to re-orient the Bezel, you will need to drain it again remove the dome and replace the gasket. Maybe that's why the Previous owner left the light off? I was lucky, and Ritchie had a great service guy near me who rebuilt mine. So I've never had to tear into it, myself.

They had a number of models and light configurations through the years. https://www.ritchienavigation.com/me.../Navigator.pdf

Great links. Thanks!

It looks like I've got to pull the compass (again) drain it, replace the o-ring and reinstall everything with the bezel facing the right way.

The PDF link indicates that the o-ring is no longer available. The video indicates that it can't be reused. Can something like form-a-gasket be used instead?

Alternatively, I may just build a plastic shim with mounting holes in the right place.

Re: Compass Reinstall

I would give one of your local Ritchie Service centers a call. One of those folks may have a gasket hanging around, or be able to advise you better on how to deal with it. https://www.ritchienavigation.com/wh...vice-stations/

The guy I used in N.J. is no longer on here, but he basically rebuilt and painted my entire compass for $60. I'd call around to the experts 1st.

I suppose as a last resort, you could drill and tap new holes in the bezel on the proper side. Hopefully you can find a gasket though. Not sure if form-a-gasket would work.

That's amazing. I fixed the bubble myself because the local quote was over ten times that amount. For $60, I'd let it be someone else's headache. I'll try to find someone like your guy.

Yeah, I think he was a rare find. I think he was retired and working out of his house. But he was listed on the Ritchie website back in 2008. He's no longer on their site. Howard Post who has NJ and Fl. #'s listed. replaced him.

Here's the info, for my guy, it may be obsolete now Paul Wilson of Capt. Howard Wilson & Sons inc.[609-296-3692] Just in case your local folks can't help.

Re: Compass Reinstall

Check these guys out too. Make sure you have your exact model # They may have gaskets
Do you know if it's a Globemaster or Navigator? looking at their pages it may be a globemaster.

Re: Compass Reinstall

Have you tried calling Ritchie with the serial number of the compass? I have an old Navigator (looks very similar to yours except mine is a powerdamp unit with a sun shade) and they were able to supply me with a nice brushed stainless mount for it at a very reasonable price. They still make basically the same compass so I'd be surprised if there were no parts available.
