Has anyone got a part number/part source for the locating dowel pins for the rocker arm bearing block in head surfaces? I think they are 3/16", but they are not mentioned in neither my old 41-54 spare parts book, nor my 58-68 spare parts book.

I seem to remember that a pin like that was used on some big twins somewhere during the eighties, but I don't remember model, location or year.

Thanks 😊 I actually have had that part number on shelf since early nineties, but no OEM p/n to search for, combined with a failing memory 🤣

HA! You sound like me. I've bought things twice before.    :embarrassed:

Good thing is that you have them.

I've got one buddy that bought the same thing three times. Finally learned though and after the last divorce he didn't buy her back.

What is the size ?
Thanks

According to Eastern MC Parts, the given dimensions are  .1875" x .495"

I actually found a long rod roller of .1895" (+.002") to fit my application better.
