Well , I went under the slide today for a look .
What did I learn .
First , make sure your propane door gas strut is in good condition before you go under the cargo door .
Second as Bobby mentioned , the set screws will have to be loosened, and if your shafts are rusty as mine they will need to be cleaned before they'll move through the cog wheel .
Also in case you didn't happen across this members pdf on the Transtorque bushing removal , here's a copy .
Make sure the manual slide locks are on if the slide is in , it may move unexpectedly is it's in and the shafts are removed.
