Post Hole

southwind26 · Mar 1, 2014

Hey Everyone

I need a little help, the shear pin on my Post Hole auger did its job and sheared but now the drive shaft is stuck on the shaft of the auger head and I can't remove it to replace the shear pin. I've tried to use chisels and wedges but with no luck

anyone have any ideas?

Beat , bang , cuss and fuss , then buy a new one.

Actually I would try lining the hole up with the piece that is still stuck inside and drive it out with a punch.

Scratch that. There is probably a clip ring on the inner shaft holding it in place. ( got to typing before I looked at picture.

My neighbor had the same problem with what looks like the same PHD. We soaked it in WD40, and used a breaker bar and small sledge. It was a real PIA, but finally came off. It had been on so long, it was rusted badly. Looks like you got the same problem.

Heat the yoke with a torch and while hot spray wd40 between the yoke and shaft . And it will pull right off by hand .

2 pipe wrenches, 1 to hold auger from turning the other to rotate PTO shaft. Line up the shear pin holes and drive old bolt out with a punch. Reason it stuck is bolt started bending before breaking, use next stronger grade of bolt. This will allow it to shear cleaner and made replacement easier.

Thxs everybody. So far I have tried some propane heat but that didn't seem to get hot enough. I tried to move the shaft with pipe wrenches and a cheater bar, I had a grade 5 bolt for a shear pin, I tried a grade 8 but that torn the shaft in half. Tomorrow I will put the torch on it and see if that will heat it up enough to move.

Spray wd40 in it while hot it's red hot . Trust me it works .

I was trying to get a stuck pto shaft unstuck beat the crap and everything I thought I could do . Tell someone came by while I was trying to get it to move . And they said heat it hot and spray wd40 in between the two . I didn't believe them so I didn't try it tell after they left . And guess what it worked like butter .
