I cleaned up all the parts.
I went down to the local Napa Auto parts store to match up an O ring for $0.65, including tax.
Applied a coating of Danco silicone plumbers grease on the O ring, the flush ball shaft, and the end of the flush ball stub shaft
Insert the flush ball, then the shaft, and put in the stainless screw from the bottom up.
Put some silicone grease on the pedal cam. The pedal cam had a film of it before cleaning, so
I re-added to help the plunger slide easier.
I installed the pedal and the pedal spring unit.
NOTE: They make a black pedal spring unit and a white one. The black spring unit fits the all-plastic pedal like mine. The white one fits metal/plastic combo pedals. Make sure you buy the correct one if you are changing it.
I cleaned the mineral scale build-up out of the pedal water valve. You can use a pick to remove the screen out of the valve. NOTE: Heads up, when you pick the screen out, it can go flying (boing) across the shop, landing in the darnedest places. Cover the screen hole with a rag to catch the screen. Ask me how I know this, 20 minutes after screen hunting, I found the screen and it is all cleaned up.
I rebuilt the flush ball seal while I had it apart. You can see which side is up by the wording and line up the locator hole.
And the thicker bowl seal.
The bottom of the bowl has a locator detent to line up with the base locater pin.
Put the clamp on before putting the bowl on. It will save you from lifting the bowl on and off twice.
Before tightening up the band clamp, check the bowl seal area to see that the bowl is centered over the ball. You can see an even black line around the ball when the bowl is centered.
The bowl clamp has the “front” word on one end, the front ends of the toilet locking ring two halves touch each other at the front center of the toilet base. There is a gap at the back of the toilet.
I put silicone grease on the water valve plunger shaft and installed the water valve. The plunger worked hard, and this made it work easier to compress.
While you have the toilet off, check the vacuum breaker for any cracks in the plastic valve.
Next up, install the toilet back in the camper.
Start with changing the cone washer in the PEX fitting. Please do not reuse the old one. It is a leak waiting to happen with being too old and disturbed. Pick out the old washer, clean up the brass fitting with steel wool to remove some of the hard water deposits, and install the new cone washer. I buy these cone washers in a pack of 10.
Then the floor flange gasket. Here is the old next to the new one.
Bottom side. New on the left.
Topside. New on the left.
On the new gasket, you have to poke through the floor flange holding bolt holes. The gasket is made for 2 or 4 bolt holes as needed. The top of the gasket is marked with “This side up”. The lip around the perimeter is on the bottom and goes down.
Then place the toilet over the floor flange, line up all the holes with a punch/drift, put the nuts and flat washers back on the lower toilet base flange, and the two rear lag screws into the floor. Hook up the water line and put the pedal cover on and you are done. Check for water leaks upon startup.

Prices change often between them, and I shop both. Some have free freight so check the total cost. While Amazon also has some of these, you need to watch as some sellers offer clones of the real parts. I cannot speak to the clone quality.
