DEX410 Slipper Assembly

[acorn28]

Hi guys, I've been running my 410R for a few months without any problems, cracking car. However, last week I noticed a small amount of black dust where the spur gear has worn slightly. On further investigation tonight, I've noticed that the spur gear is not turning true. I changed the spur gear but still had the same problem. I'm guessing its an issue with my slipper assembly, which I've stripped and rebuilt with no success.

I remember seeing a post a few months back re problems with the slipper clutch plates , could this be the problem? Any help greatly appreciated. Cheers, Rich.
