Not the same but better!
I replaced my collar because of a broken spring, I was originally going to just replace the spring but the grip on the collar spoke to me. After using it over an 8 hour shift I'll say it's holding bits perfectly and changeouts with the new collar are much easier as it can no longer slip out of my fingers. Excellent product.

Collar assembly
It would be nice if there was a picture showing the assembly. The parts need to be put in order or you may have to do it twice.

What fixs the chuck on an impact driver to keep it holding the bit in it. Right now if you turn it downward the shaft with the drill tip will fall out the impact

1 Remove retaining clip from collar with pick tools
2 Hold assembly together after clip is
3 Slowly remove spring, collar, inner spring,
and ball bearing.
4 Replace with new parts from kit starting with bearing.
5 Install spring with built in retaining clip next, this holds ball bearing in place, and will hold tension against collar.
bearing goes on top of spring, so that spring/ clip is on the side closer to the drill, while bearing is closer to the opening for bits.
6 Install new collar next, followed by remaining
7 Using a flat head screw driver, I held the new retaining clip in place while using pick tool to spread it enough to get it back in place on the shaft and holding the assembly together. You're done.

I removed the snap ring which held the quick connect on the drill. I found the spring broken which holds the little ball in place. I replaced the spring with the new parts and it works great. The only difficult part of this repair was getting the snap ring back one because it is so small. Thanks for the kit to repair my impact driver.

Parts Used
Removed the snap ring at the tip.
Removed the following parts: washer, large spring, cowling or cover, the broken smaller spring and ball bearing.
Replaced broken spring with new one.
Reinserted ball bearing in front of the hook in the spring, replaced cover, large spring and washer.
Pressed the washer downward and placed the snap ring at the tip.
I needed a small handled tool that has a hook at the end to pull the snap ring and work it into the groove it sits in.
Really easy fix. Can be done in five minutes or less.
