Default Re: Flathead Lifter Adjusting - "On the Bench"

The info I'm putting here today is more-or-less a "tip" about using the original Johnson tappets from Topline-Automotive, just got off the phone with Dave and learned something even I wasn't aware of until just recently??

The adjusting nuts are mfd with a "crown" on the tops of these Johnsons, Dave explained it was sort of a quick way to determine whether or not it's their lifters? According to him the "offshore" pieces are perfectly "flat". Being "flat" they cannot work correctly!

I suspected this just earlier today and called to confirm. It isn't something that would have ever affected any of the builds we've ever done in the past or today!

Thanks, Gary in N.Y.

P.S. On a side note, the demand for these lifters is still so strong Dave also let me know they are running off 50,000 lifters this very week. I consider that to be excellent news at least in my eyes!!
