I purchased them from Chris/Rvenge during one of my large parts orders. FWIW, I reused Dustin's '96 R/T TT's original stuff (ensured that the washer was not flattened), and his Fluidampr also has around 3,000 miles between SoCal and ND.Where did you get the revised bolt and new washer? I'm reluctant to use the early version with the recessed square drive.

You're off base on this one... The locating face is 100% on the gear. The gear sits proud of the crank and the crank never contacts the balancer. It's done that way to retain the gear. You can't have the gear rattling around beating up the crank and the keyway.Having two separate but simultaneous axial location faces was a huge design no-no back in my aerospace days. Primarily because its practically impossible to share the loads equally and consistently between both faces, so one of them acts like a spring and this can result in lost tension in the bolt - and it backing out.
For an assembly like this, I'd expect the primary location be the inner face (the end of the crank). The cam drive is pressed on so its not going anywhere. A dished spring shim would provide for any axial movement in the cam sprocket.
I think I may use safety wire on the replacement bolt.
Excellent. I really hope I'm an outlier on this issue.I purchased them from Chris/Rvenge during one of my large parts orders. FWIW, I reused Dustin's '96 R/T TT's original stuff (ensured that the washer was not flattened), and his Fluidampr also has around 3,000 miles between SoCal and ND.
Mine checked out fine today** 130ft/lbs immediately clicked and bumped up to 137 afterward. This is with my old Craftsman unit that I had tested against a master set at Matco a few years ago.
