lower drive shaft broke in two

Trudy from GROVEOAK, Alabama

Difficulty Level:
A Bit Difficult

Followed the directions on the video on your site for how to repair this. The only difficulty I had was getting the retainer ring off. It would not budge, so I had to take a hand saw and cut the plastic spool cover in two and then cut the retainer ring in two. I had replacement parts, but it was a battle to get to that stage. Once I got t hat off, I could replace the lower drive shaft and complete the repair as per the video.

Lower flexible drive on string trimmer broke.

Disassembly is pretty easy, just some Phillips screws, a push button release, and a clamp, and the shaft just pulls out easy. There are a couple of helpful videos on YouTube to walk you through it, although I didn\'t need to do everything the video said to do, as far as disassembling the string head completely apart, not necessary for my particular model which is a Troybilt. Over all, it was just as easy as the upper flexible drive I did a few years ago on the same trimmer.
