IMCO grader blade

[Dave in MS]

Need to know how to replace bearing in a vintage 3 point IMCO grader blade. At least remove the top cap from the spindle housing. Appreciate any help

Look underneath the pivot area , there may be a very large bolt head , if it's there it will need to be loosened. I'm fairly sure it is similar to the early Ferguson blade,
the bolt threads into the cap , there may also be a huge lock nut under the cap, if so it will need to be freed

No dice but thanks for responding. I will post a pic of it with the blade removed later today.

I half assed fixed it. It's not the kind of work that I'm used to doing but it'd done and it will have to do. I lent this thing to my bil over a year ago, then he lent it to someone else who broke it and welded it back crooked so that the index pin wouldn't fit through the holes. He must have welded it with the pin in the center hole cause I had a heck of a time getting it out. Many days of soaking with penetrant, and many cuss words before it came out. I was going to torch off the carppy welds and straighten out the spindle housing but discovered that my oxygen was empty Thus the hack job. I drilled each index hole so that the pin would go in. It looks ok, nobody will know but me and it indexes like it should. Besides I bought it used more than thirty years ago, and could count the times using it on one hand. Now I need it to backfill a trench I dug to bury a wire to my new shop.
