Spindle grounding

This was how I did it. See post #26

Looks really nice, great job ! I ended up filling the inside with silicone, though know it was not necessary, but I'm just too worried about the sealing.. this way I'm sure it's all sealed properly. I made sure nothing was getting in the water circuit by putting some perfectly sized metal stems in it.

Just letting it dry for the moment (24 hours recommended).

What do you mean filling the inside up with silicone and what are the metal stems. There should be two O-rings to seal the water ways.

See how the three factory wires go through a white kind of silicon water-proof gel coat ? Well, I recoated that because I wasn't happy with how it looked. Next, next to the water holes there was some glue that was put in the factory, you can see it because it's only around the water holes. I put silicone all around the spindle like that:

But, as you can see, some silicone could get into the water intakes, which is not good, so I fitted a perfect fit metal cylinder through both of them while putting the cap back on to make sure no silicon got in there. I got the word "stem" from Google Translate, hoping the translation would make sense :) May be "metal stick" would have been better :)

I have to replace both o-rings of the cap intakes (main intakes when the spindle is closed), i'm not happy with those that are on there, plus one of them is broken, so I'll replace both at once. I'll get new ones next week.

Did you put the O-rings back over the waterholes in the spindle case on the inside? You don't need silicone all around the spindle case or you will never get it off again

On the inside there were no o-rings on my spindle... instead there was some white glue as shown in the picture above (you can see what's left of it after I got the cap off). I don't worry about getting it off, silicone won't glue it too hard, just ensure a good natural seal.

OK have you looked in the cap? Is there not an indented ring where the seal should sit in on the underside of the water inlets. It is very unusual not to have O-rings.

It does have O-rings I can see them in the Black End cap. Can also see the tell tail black outline of the ring on the Stainless body.

Don't put it together just relying on Silicone. You need the O-rings.

If water gets into these Spindles they Go POP Big time and can take the VFD down with them so be careful.!!
