I thought I'd share this with those of you who have spur gear issues. Keep in mind that the spur gear is designed to be sacrificial and to protect the drive train.
At my last bash session with El Pirata (aka Master of Disaster), I managed to smoke my spur gear, but not in the typical manner that they get smoked. Check it out.
The Savage turned out to be better than my late night inspection from before. If I go on the cheap (meaning no upgrade) my total cost for damages will be about $4. The clutch shoes were not any more burnt than they have been. The water in the clutch bell actually saved them from any major work. The spur gear on the other hand is toast (and that is all I have to replace). The rest of the drive train is in fine working order. Tranny and diffs all saved by a properly set up spur gear (lesson here for everyone).
Here is the inside of the spur. Note the shards of the little friction pad burned/melted into the outer ring of the spur gear.
Here is the outside of the spur. Note the meltage around the bushing. Going to need a chisel to dig that thing out of there.
Finally, note that none of the teeth are missing or screwed up. The friction segment of this slipper clutch did exactly what it was designed to do. It ate itself before letting the rest of the drive train get torn up.
