Dem bad boys are exactly .025 per turn . I had to source a 3/8-40 tap to
make a locknut that was missing (bored and retapped a gr5 5/16-24 since the
others were 1/2" on the flats). These came from an opened package from a
dealer on ebay (Harley dealer in Pa. IIRC) for a very reasonable price .
There's no tick when cold , and it's not loud when hot . I'll just feel
better KNOWING that I ain't about to spew needle bearings throughout my
motor . The PO kept a lot of records for parts and work , lifters ain't on
any of them ... and at 70k+ it's due for a second replacement set anyway .
Shirley , get Jinks and Spunky whatever they want offa the top shelf .
