(4x) Truck tension springs for second generation chassis (Hankyu 9000, HST, ICE, KIHA 40, 016 & 015 Powered Chassis etc.).
When replacing these springs we recommend using the sharpest of tweezers holding the spring by the top loop and locating it on to the chassis. Then by retaining the top loop using your finger/nail, use the tweezers again to gently stretch the bottom loop down and on to the truck hook. Take care at this stage not to let the truck fall otherwise the first spring may come adrift, and turn the chassis around to repeat the process for the other side. Make sure that the main spiral of the spring sits within the profile of the chassis and won't foul the loco body when this is replaced.
