I can't figure out how to remove the governor from the borg warner overdrive. The unit is supposed to unscrew. The wrench is a 1.5", but there is a taper and the wrench won't fit. I don't think any wrench big enough to fit the nut would fit in the small space available. I've looked up other types of borg warners and they have a larger area around the nut to put a wrench.
