Here are some pictures of the spring compression tool that I built to safely disassemble my TR250's front suspension. this tool would work just as well on a TR6. I'm not quite sure how all the official tools from Moss or TRF work but I designed mine to use the bottom spring tray that ends up being attached to the lower a-arms. This just allowed me to very safely remove all the energy in the spring and remove it. The hole kit cost me around 5 bucks. The threaded rod, washers, and nuts from came from the local hardware store. The rod is 2 ft long, 1/2" threaded rod & the aluminum plate was a scrap from a friends machine shop.
