I noticed reading those last two pics of the text out of the maint. book that it talks about putting washers on the pin then putting the block on the pin so it doesn't bottom on the pin. And then take off the block and washers and put them on the other side and the difference isn't more than twelve thousandths, .012". I did not have any washers when I took mine apart, on the pin on either side. Now, I have had this intermediate shaft out about thirty years ago when I had to repair the mast tube. But I never did take the intermediate shaft apart. So this time when I took it apart that was the first time since the truck was new in '74. I'll try this and I might have some real thin washers in my aircraft open stock. We'll see what happens with washers on there, then I'll put the blocks on with nothing and see what the difference is.
