The idler pulley spring that holds tension on the ground drive belt snapped on my Z254F. I found and ordered a replacement spring, part number 532196105, but it's not obvious to me where the hooked end of the spring connects to the frame or plate.
The spring in question is #15 on the illustrated parts list image below, and is located under the seat. Could some kind soul with a Z254F post a picture showing where the fixed end (the left end of the spring in the illustration) on their spring is attached?
