Hi Nelson,
I think I read that there were two B&B numbers floating around for the
pressure plate. One was supposed to be firmer than the other. I think
the two numbers are in my reference doc. My brother sells industrial
bearings and he told me that RHP is a good bearing but like you, I think
the RHPs sold as release bearings are pretty weak.
By the way the site looks great. I hope we can gather some good data.
I'll forward mine to you when I tear it down and add the LuK.
Talk to you later,
Jay
