Questions on toilet platform and plumbing..

[59ORLander]

Hey gang, it has been a while..we're getting after the back end of the Overlander, trying to resurrect the original toilet and black tank, and I've come upon a couple hitches.

What is the sequence for removing this pedestal/platform section above the black tank? I've unscrewed all the screws from the black "outer" ring at the toilet junction, removed all of the trim from the platform area, and pulled up some, but it appears the black tank iron is connected to the black plastic somehow. Is the plastic tubing just "set in" to the black, or is there probably some strong sealer or glue there too? Upon lifting, it appears that the tank is getting pulled up too. I'm not 100% sure I want to get the tank out, but the main project is rebuilding the plywood on the underside, as I've cut out all of the rotted wood down there. The metal bracket that goes across the very rear frame brace to the heavy main frame is gone, but I can rebuild that, I'm sure.

I also am not sure about the gray/black valve on the tank. It's brass inner screw part (with the shaft that gets pulled up/down to control the black flow) comes out but the shaft itself is rusted off. So I'm stuck now knowing if black water from the tank would go out or not!

What do you think? Should I simply start just cutting all this apart and start from scratch and get a new tank and build a new platform, or do I have a snowball's chance at salvaging what I"ve got, here?

Tanks for any tips

The black tank on my 67 appears to be good but I am not taking a chance on 50 year old plastic. All my tanks and plumbing will be new.
Spent too much time putting in New floor and frame to have the old one spring a leak.

I think you just unscrew it, I did just read another thread and that is what they were doing.

I just took mine apart, a 1986 and the toilet rotated off flange it was held by the T bolts. The flange was screwed to the platform and there was a hose clamp between the flange assembly and the tank, sealed with bedding compound. The flange assembly is: flange, street 45 degree, short 3" pipe.

Hmm, well now there's an idea! Thanks..haha I hadn't even thought of trying that.

Having said this, I believe we are moving away from the idea of a black tank, period. I'm thinking we are going to rip/cut/unscrew this all out of there and start rebuilding a platform and the subflooring and just go with a dry composting toilet. After exhaustive research, it appears there are some good options out there ranging from a bucket and shavings(and a nice mahogany box that I can make myself) all the way up to a vented electrically powered $1,000.00 model, depending on our frequency of use and smell acceptability. I'm not picturing anybody poopin" in this thing in the future much outside of emergencies, anyway
