When you get all the bolts out, GENTLY pull the snout off. If you pull it too forcefully, who knows what all will come out with it--like the input shaft and its accompanying needle bearings. The input shaft is only held into the transmission by the snout and it can fall out right now onto your dirty floor that you forgot to clean up.
Bearings are just like peanut butter sandwiches...the peanut butter ALWAYS falls peanut butter face DOWN and bearings always stop rolling (under the bench) in the biggest pile of dirt and shavings they can find. But you can always think on the bright side--if you get junk in your bearing then you will get ANOTHER opportunity to read my manual as you pull out your transmission to change the input bearing from early failure
Be careful!
