[john walker's workshop]

the installed, outside diameter of all the new syncro rings needs to be measured with calipers and be within spec. the inside of the pressed on dog teeth can wear oversize from the rough surface of the syncro rubbing on it during it's lifetime, and even though the teeth look nice and sharp still, they often need to be replaced if they allow the the new syncro to expand too much. the shift sleeve has trouble passing over a "fat" syncro. use a standard gear oil like kendall 80/90 GL-5 and hike the short shifter.
