woodruff key stuck?

Recommended Posts

I was starting to rebuild my BGB this weekend which should have been a 2 hour job, except Mr Murphy showed up to help me out. I could not remove the woodruff key on the shaft where the pump pulley mounts, I tried for an hour with a slim screwdriver, a pair of channel locks and heat from my torch, it would not budge. I had to disassemble it from the pto side pushing out the spacer seal and bearing, not the easiest way, thats for sure. Once I had the cross shaft out and bare I tried clamping the key in my vise and tightened it with a hammer, it would not budge, I tried until the metal tore away so much I could not grab it in the jaws, and yes I tried heating it while in the vise, I finally got out my Dremel tool and a thin disc 1 inch dia. and ground a groove down the center, the disc went halfway in and fit the slot perfectly, two taps with a hammer and drift punch toward the center and out it came. I know there has to be a better way, has anyone else had this happen?

Hi, We usually get them with a pair of diagonal cutters. You need the ones with the cutters close to the hinge, like Snap Ons. etc. I just bite them on one end and pivot the cutter up. If this don't work, I then take a punch the dia of the key thick and go to one end of the key. I put the shaft on a flat steel block I have, weight about 50 lbs. Then I use a heavy about 4 lb hammer and usually the key will just roll out of the slot. Drive one end down and the key will rotate up. Then grab with the cutters. 2 points. Must have a solid flat surface for the shaft and use a heavy hammer. Light hammers will just swell the key and it won't move. Sometimes a cold chisel driven from one end will push them out. Al Eden

I've had luck using a chisel and laying it parallel to the shaft with the edge biting into the end of the key. Then hit the chisel with a hammer. I've also done it the ways Al suggested. Whatever works.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
