Asplund Jex blade change info

[3fingerchip]

Can anyone give me a clue as to how to remove the blades from this older drum chipper. I have removed the four hex head bolts but am overlooking some sort of set screw or something. Any help would be appreciated.

It that chipper the same as a JEY, if it is I can copy my manual and mail it to you.

put a big bolt into the hole the little one came out of do it up till tight and hit either end of wedge with a hammer to loosen it.
