I replaced the run capacitor on the Delta 50-850 dust collector today and it is working.
The replacement capacitor is the smallest diameter (the length is no problem) I could find but is a tight fit for the existing external cover. I’ll add a second bolt the next time I’m at DMS and some electrical tape on the contacts that are inside the cover for extra measure. For now I think it’s OK to use…
I’ve connected the vacuum tube to the Shapeoko 3 XXL dust shoe and left it that way as a hint to users they can start using it.
