The ng has been very helpful for my other questions, so here is a new one.
The Grand Wagoneer tailgate electric window regulator has a power spring that helps the motor raise the window.
This is a spiral spring, also called a clock spring, helical spring, or properly, power spring.
The regulator I have looks like the spring was replaced, but not completely re-coiled as compared to other examples. Thus, it provides less lifting help.
My question for anyone well-versed in mechanics: is there a spring compressor for large clock/power springs? A net search has not helped.
I would like to remove this spring, wind it one turn tighter and replace it.
Any recommendations would be appreciated!
