|
|
I've got my 1953 M38A1 Dana 25 apart for my restoration and I need help in understanding the Bendix Joint.
The previous owner/mechanic filled the U-joint cavity full of standard wheel bearing grease and the axle just carved a tunnel in it, so I pulled the axles and put them in my parts cleaner. During the cleaning process one of the axles fell apart. Looking at the maintenance and the operations manuals I see how to put it back together, but fail to find an explanation for what the small staked pins purpose is. Can someone explain this to me?
Thanks,

If I remember correctly the pin holds one of the balls in the center of the axle for the others to float around... there should be a hole in one of the axle halves and a hole in one of the balls put them together and the rest go from there. They need a bit of nudging to get put back together but they will go... _________________ Hal, KB1ZQ

Thanks for the drawing Wes make it easier to ask my questions...
My #4 pin is still in place, but the rest fell apart during cleaning. Is this anything to be worried about?
I think I got it now after additional research...the #3 ball pin hole is drilled deep allowing the pin to be pushed in flush during assembly and the last step is to shake the #3 pin into the center ball and lock it in place with the #4 pin which keeps it from falling back into the deep hole. Right?
Thanks,

Two of the balls measure .8710" and two measure .8725"...the center ball is smaller at .8115" . Are the different sizes an issue or is that normal?
