Cummins told me to try doing a top end set, sometimes that takes care of it. It reduced it but didn't eliminate it...so out came the rear rocker shaft. Number 4 & 5 detent holes have obvious wear in them. In went the new shaft and now I can't wait to get my rad back to hear my motor all quiet and tap free...


Top is worn one, you can see the wear towards the upper side of the hole
Bottom is new replacement for comparison
Do you replace shaft and rockers?
