@dluck, the picture kind of shows the table is not seated all the way down on the top spindle. You may have to jiggle the table a little to get it to sit flat. I have that issue with my table.
Look closely at the circled area in the picture and double check the horizontal arm is seated on the vertical spindle, hopefully that's it...best wishes
Agree with @Sharon_is_SAM. The bushing should be seated all the way over the sleeve. It's sometimes hard to get it all the way down. Be sure the clamping lever is not tight. Twisting back and forth can help.
edit to say how slow I am at snipping and editing a picture. Everyone beat me to it.
@BridgerSunset, your summation is very complete, two clarification: #4. System was flushed with original parts in place. After flushing decided to remove all old parts and replace with new.
#7 From what I can determine, the hole was from the inside to the outside. There were deposits inside the tube where the hole originated and tube on the outside looked original with the exception of the hole.
@grassgd, your observation is describing what I am seeing. There has been NO evidence of white powder in the convectors or tubes, just what I documented on the reservoir connections. While the inside of the convectors appear clean, I have tried to show what the inside actually looks like. While it is free of white “stuff” there appears to be corrosion inside the length of the convector.
The new pictures are the bottom convector in the back I removed today. An abundance of jelly stuff in both ends as well as discovering the jelly in the tubing.
We also have a 2021 T@B 400 BD with the original AGM batteries. So far I haven't noticed any battery degradation and we just completed a three night camp off grid. I know the good times can't last forever so I'm interested in what happens next.
I also have a 2021 400BD and noticed my batteries struggling to keep up last fall during an extended trip with several days off grid. Swapped out the 2 AGM batteries for a single 200 ah lithium battery this spring. Freed up nearly 100 pounds of weight in the process.
