Is there any suggestions on how to get the pin out of the clutch/low speed petal to get the shaft out? The shaft is worn to the point there is way too much slop in it's action. We have already heated it red hot with an acetylene torch, and beat on it with a punch. It is so hard to clamp, we are leery about drilling the pin out, not sure we can keep the drill straight enough. All I have heard is it is a nasty job, and so far it is proving to be a real pain. If it makes any difference, it is a '26 petal and shaft. What has worked for others???
I think you are talking about getting the pin our of the low speed notch located inboard on the hogs head. When I removed mine I was going to install a new shaft and low speed notch anyway. I did this with the hogs head off. To remove the low speed notch, there is no need to drill through, just far enough on each side to clear the notch piece. This also applies to removing the pedal from the old shaft. At the pedal the pin is peened over so grinding off the heads once the shaft is out makes it easier. If that doesn't work, just cut the shaft since it sounds like you are going to replace the shaft. If you are doing this with the hogs head off and intend to put o-rings on the shaft, be sure to chamfer the hogs head so you won't completely crush the o-rings.
If all else fails, drill through the pin with a drill smaller than the pin leaving the edges of the pin in the hole. It should be easer to get out after it is drilled. You can even use a very small triangular file to file a slot through one side of the pin after it is drilled.
Remove the pin rivet head on one side. Drill slightly smaller than the pin diameter. Drill just thru a depth equal to the pedal shaft diameter. Don't drill completely thru. Now using a punch, drive out the pin.
If you are working on an aluminum hogs head be sure to back up the shaft before you try to drive out the pin. It is a good thing to do on the later hogs head too but they are much stronger. I just cut the shafts on the early hogs heads rather than take a chance on braking them. You are going to replace the shaft anyway so it's no loss.
When putting it back together will spring pins work instead of solid dowel pins? I've used spring pins in other applications. Much easier than pounding over solid pins. In some cases I've used a smaller spring pin inside the correct larger pin. This gives a double wall and increased strength.
Ken, I tried them and only worked for a while. They will work their way out or break, more pressure on them than you would think. KGB
