Brief Description:  O-ring replacement in Sioux drill - part 2

The one common denominator seemed the be that o-ring in the handle assembly. I had even purchased a box of replacement o-rings - but I just couldn't seem to get that little sucker out of there as it sits down in a channel and it's very hard to get the pry tool in there and get a grip on the rubber o-ring and lift it out. I even asked Bob what the trick was and he said that he just used my pry tools and got it out...

So when the drill quit today, I was determined to fix it. I worked and worked and finally got that o-ring out of there with the 45 degree pry tool. Now for the also-hard part of putting that o-ring down in the bottom of the handle, and stretching it down into the channel. I could get it to seat on one side, but then the other side would pop in, popping the first side out. There isn't room to put a bunch of tools down in there (it's narrow, remember) so I devised a way to keep the o-ring seated in the channel by using a long, thin piece of stainless steel that I cut from my remaining sheet.

With the stainless steel tab, I was able to hold the one side of the o-ring in the channel and then with a flat head screwdriver, I could stretch and seat the other side - and the o-ring popped right in place! I put the drill back together and it works great again! This is my notes for when I have to fix that drill again... :) O-Ring size is #83
