Front bolster pin

[Bern]

Anyone know what the drilled hole is for in the front support pin for the front axle for the 5000-7610
series tractors? As you can see, the tractor I'm working on broke the pin in half right where the hole is;
first I've ever seen of that kind of failure. I'm frankly surprised that the front axle did not fall out.

It shure is handy to stick punch in to help get it out when cannot get screwdriver under flange.

The one I drove out would have never came out with a punch set on an angle. I had to lay the bolster on the ground just like you see it and smack it directly with a pretty big hammer. It gave me a fight!

That pin fits dozens of tractor models and thinking the hole may serve a purpose, such as a grease passage, on a specific model so production drilled them all. Just a WAG.
