[Fot] Rocker stand studs

[Jack W. Drews]

Again this weekend one of our TR competitors suffered valve train 
damage because the rear rocker stand stud backed all the way out, the 
shaft broke, and rockers were damaged. The studs appeared to be grade 
8 studs, the one that backed out was not damaged, and the threads in 
the head were not damaged. On this particular engine, the rocker 
shaft stands were steel and were in as-new condition.

I've seen multiple occurrences of two failure modes -- one is 
breaking the end studs, the other is studs backing out. Both 
resulting in collateral damage.

What is the collective wisdom of the list regarding

---prevention of breaking?

---prevention of backing out?
