So, I'm swapping some parts from one aluminum hogshead to another, and I'm really having a hard time getting this clutch fork shaft out of the hogs head its a early one came off a 12. I took loose the bolts and safety wire that clamp around the shaft and found that there is a keyway that is made into the brackets that hold the clutch yolk on. After loosening everything and sliding off the brackets from the keyway I cannot get the bracket off the shaft, because there is not enough room on one side nor can I pull the shaft out on the other side because of the keyways are hitting the hole to which the shaft goes in. I looked to see if the keyways are removable but they seem to be part of the shaft one solid piece. I know I must be missing something any help would be appreciated. Thanks
Mike, The keys are removable from the shaft. You must remove them to get the shaft out as well as the arms off. The keys are 1/8" x 3/8" radius.
Mike: David is right those are woodruff keys and look like this
they are removable but sometimes need some gentle persuasion!
Thanks David and G.R, I put a pair of vise grips on the middle of the key. then I taped the endow the vise grips with a flathead screwdriver and hammer and they came right out!. Thanks so much
Be very careful with any sort of hammering. The aluminum hogsheads are brittle and shatter easily. Even light hitting should be backed up with heavy metal to support the aluminum.
There is a specific type of wire cutter (the proper name escapes me, but was discussed some time back on this forum, and not entirely agreed upon), that can work well for removing Woodruff keys. The cutting edges are 90 degrees from the handles (unlike the more common cutters in which the cutting edges and handles are basically straight on). With these, you can reach straight in, the cutter bites the end of the key, and a little leverage pulls the key right out.
Wayne's is the second recent post mentioning cutters with the blades at right angles to the handles, for which neither poster could recall the name. These we call end cutters. As nail pullers in carpentry or horse shoe removal, they are often referred to as pincers.

Oblique wire cutters.......used the all the time in my telephone days to pull staples and such. The handles have a curve that allows you to use it as a fulcrum and pry things.
Just purchased a pair at Sears.
