Would you all recommend a really deep 8.5mm socket to tighten that nut. I initially used a pair of needle nose pliers to tighten it down. I found it very hard to get too, as this was my first clutch with 3 pairs of shoes. I suspect that the tool I used gave a false feel of tightness, and I did use a good of thread lock (which made it extremely difficult to remove).

As I've said in another thread, this is my first monster truck, and so far I'm liking it. Thanks once again for all the great answers.
