Help for 4010 rockshaft housing removal

I had to remove my 4010 rockshaft last year. Sounds like you may be hanging up around the cam follower. It is not fastened...just make sure you hoist slowly and watch and make sure it is not in a bind. Also be prepared for an aggravating job when you put the housing back on. You must get the roller of the load selector control link (in the valve housing) on the backside of the cam follower without damaging the linkage or follower. I remember we had quite a time doing this because it is all but impossible to see the roller. Also, I had my rockshaft valve assembly removed (think we removed it to try to see the roller better) and someway got the valve operating lever (sector gears behind quill) out of time. Had to remove the valve assembly a couple of times to get the timing back right before my dash control lever would operate the rockshaft correctly. Good luck!
