Hassler spring install

Post by Wingnut » Sun Sep 14, 2025 9:31 am

Hello all, after the rebuild of a friend's rear axle we're having issues putting the springs in place. I wasn't involved in their removal so I didn't see how he got them out. This is on a 1920 touring with, what I'm told, is a California top. He has it on a lift which is a difficult install operation for me, I'm used to working on the floor. We've tried compressing them and wiring them, can almost get it but no cigar. Does anyone with experience in Hassler springs have a recipe method of install. We thank you for your support, Wingnut

Hasslers came with a dedicated tool to compress the spring. However, you can compress the spring with it in the bracket with a homemade version using a piece of threaded rod, two nuts, a washer and a flat piece of steel with a hole drilled in it as I described here:
