Default GP Piper Cherokee conversion

I'm in the process of converting a gas Great Planes Piper Cherokee to electric incorporating a set of all metal HK servoless retracts .This will make it a Piper Arrow.

I actually bought the plane used from a buddy and he had already added air retracts. What a project. All I need to do is switch them out. Sounds easier task than it is.

I'm removing the air retracts and the first thing I noticed on the HK steerable nose gear is that besides the normal arm that the servo pushrod/ clevise rides up and down on while the gear lowers and raises, there's a small compression spring attached with a screw to the base.

Where does the other end of the spring attach to ? What does it do? Is it a centering spring?

Thanks ,
