Y-Guys:     Reed & I cranked my new engine last nite, every thing went well,           

             no evil noises but, several of the rocker nuts are backing off. I bought

             the.003 over ones from Mr. Schuman, but for some reason, they will

             "start" into the rocker and then they try to pull the threads out. I've

             gotten one to work(Vern told me to use them on the most "worn"

              rockers only)

                Does anyone have a suggestion(S) or????? I've got a set with the Lock

            nuts on them but, they're a pain to adjust!

                                                   Thx

                                                    Bill

I've had the same problem with the oversized ones, they just won't go without tearing up the rocker.  You can try smashing the threads on the adjuster a little this has worked in the past if they aren't too bad.

Every time Tim sees me with a ballpeen hammer in hand, he asks "adjusters loose again"?

I've come across one piece adjusters that require a 7/16 in. socket and others a 1/2 inch.  Does the size difference indicate a stock vs. oversize adjuster?

Mike:

I have found the 1/2" are standard, 7/16" are oversize.

I've got 7/16th one one side and 1/2" on the other side. I got some lock nut ones from Tim & when I find a loose one I replace it with one of those. Only a pain in the butt one time.

Bill: re the rocker thread problems. I don't know for sure, but is it possible you are using the .003 oversize interference screws in rockers that were originally the early jamb nut style?. From reading Eickman's Y-Blk book, pages 36 & 37, my impression is that the threads were different. If so that might explain why it damages the threads..

The Ford .0023" O/S adjusting screws should typically have multiple vertical scribe lines on the hex flats.  An old Ford line mechanic told me this, in addition to checking boxes of NOS Ford adjusting screws.  If I recall correctly the adjusting screws have a Major OD diameter size that tapers.

I'll also look at the different hex size theory, re std and O/S threads.  Never heard that before.
