I have a HRX217VKA that I purchased 4 years back. One of the washers on the hinge pin fell off and I replaced with a new one from the hardware store. When I pulled out the hinge pin the springs came unwound. I haven't figured out how to rewind the tension when putting the hinge pin back in place to keep tension on the chute. Any idea how to rewind the tension on the 2 springs when putting the hinge pin back in place??
