I had to do this on my Honda HRX217TDA after one of the push nuts came off after 14 years of reliable service! I did this reinstall of the tension springs by myself and followed the advice to install the springs first prior to the retaining rod. Working alone I could only take two photos showing the springs mounted in the discharge guard (with no rod) then the setting of the guard in its proper position in the mower base and then installing the rod with the press nut on one end. The rest is just pushing the rod all the way through (slowly) the springs to the opposite side then install the remaining push nut. I will try to upload the photos but haven’t ever done that on this forum’s site so it may take me a while to figure it out. Happy American Independence Day!
