PSA: Found a weird trick for stubborn door operator adjustments in a 1970s building downtown
The service manual was useless, but the old super said to check the cam follower arm for a hairline crack, and sure enough, that was it. Anyone run into a similar fix on those vintage Dover units?

@olivia_barnes97 nailed it, that's just how EVERYTHING made before 1990 works now.

Classic. The one thing the manual doesn't cover is the part made of 50 year old pot metal. You'd think they'd have a page that just says "check if it's broken" with a picture of the whole unit.
