Dialogue
 * There is been some trouble in our best pulverizer, The Cruncher. Some of those damned Dredge rebels managed to steal the toothed cog needed to operate that machine. Of all the machines to mess with! We can't meet our quota without the Cruncher! A master gear won't get 'er up'n running; it must be that toothed cog. Get it back, fix the Cruncher, and take care o'any Dredge ye find. And be quick about it, or it'll be fifty lashes for ye!

Followup
 * Unknown

Walkthrough
The arrow points through a gate. You will need to open this gate. Simply grab a master gear from any nearby gearbox and place it in the gearbox that operates the gate. A short way through the gate you will find the rebels. They are constantly moving and the Spirit Keepers are hard to isolate. It's best to simply observe the patrol movements then pick them out one at a time. The Spirit Keepers will resurrect fallen rebels so you need to take them out first.

One of the Spirit Keepers (not necessarily the last one slain) holds the toothed cog. After dispatching the rebels, place the cog in the gearbox marked by the star on the map. Then return to Krak Flamewhip for your reward.

Tip: This quest is a lot easier if you do not take it, then open the gate as above and go in to kill the Dredge troops. This way, the Spirit Keepers will not be there yet (they spawn after you take the quest). This will make killing the other troops easier and killing the Spirit Keeper after taking the quest also much easier.
