Is the spring broken or did it just pop off the shaft?

Appears from the pic that you can move the spring to the left, up, and back to hook onto the shaft behind the arrow on the right.

If that is all that needs to be done it is easily accomplished in less than a minute with a screw driver.

Thanks for the response. Sorry I didn't mention that is the new spring in the photo. The problem is that I can't get the leverage to load up the spring to hook it under that shaft. I don't know if I need to slide the shaft out of the bracket that the left arrow points to and try to get it on that way, or if there is another way it should be done.

It's more complicated to explain that to do.

Leave the shaft alone and use a screw driver (from the right) or vise grips to lever the spring up and back till you can hook it behind the shaft.

Be careful cause it is easy to stab yourself with the screw driver if you don't know what you're doing.

Thanks, I took off the 2 cotter pins and slid the shaft part-way out of the bracket, set up the spring and slid the shaft back into the bracket. Worked out great. Thanks.
