How to replace Locking Screw. Replaced agitator collar. While I was in there, I installed the stem mounting kit. I did the stem kit and bearing about 10 years ago, so I only did the stem seals this time. The special spanner wrench is required for this job. The job is pretty straight forward the collar is under the inner tub. I put 2+ hrs for this job, as the I had to drill out the broken set-screw that holds the plastic agitator in place, plus I wanted to clean everything real good. Thankfully, I could just pull the agitator out with the shaft attached for drilling. I went with a larger stainless steel sheet metal screw (coarse thread) and a new "o-ring" ...I actually used a small modified grommet to make the o-ring. I went with a larger screw, as I need to go a size or two up to get a good bite since I had to drill out the old one. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
