Aaron, I checked my Crown manual tonight, but there's nothing in it about adjusting clutches. Sorry! It may be better for you to contact the owners of Series I Crowns on the BCM forum, most of whose buses have manual transmissions and presumably have clutch adjustments as part of their routine service.
The Super IIs were made in 36, 38 and 40 foot sizes, so I'm guessing yours is a 36 footer. A pusher that short is a rarity, and one with a 6-speed is especially rare, so you may possibly have a unique bus. What engine does it have? Was it always a WA bus (with the double rub rails and 8-way flashers)? What school district had it? Do you plan on converting it?
