Pressure ring on Ram adj p.plate replacement
Posted: Sat Mar 10, 2018 7:02 pm
I have a Ram Adjustable Pressure plate on my Chevy. I ordered a new pressure ring from Ram to replace the one I have been running due to having it ground to max tolerance. The new one I received of course has the bosses the springs set on and these were not drilled for clearance when the spring collapses. There are also 3 bosses between the 6 bosses mentioned above. There is only 1 of the three drilled on the used pressure ring and of course none on the new one. My question is... simply WHY? Why no holes drilled? Why only 1 of the 3 bosses drilled? Also they are .525 not .500 in diameter, kinda an odd size.... Is the 1 of 3 a balance thing? I want to just drill it to match my old one and drill the holes .500 as I do not have a .525 reamer.... I will call Ram Monday but wanted to put it together tomorrow... oh.... and it is a Tim Hyatt (R.I.P) modified pressure plate, I might call his son Chris and ask him. I just wondered what you guys thought.
