Picture quality. There are no unusual markings anywhere. As I posted above, even the broken set has wear marks on the lifter body that look no different than the surviving sets.
I'll post additional pictures later.

Yes. The rivets are staked on. It's almost impossible to tell if the rivet let go, the link bar hole got wallowed out or a combination of the two.allencr267 wrote: ↑Tue Oct 05, 2021 1:11 am Hydraulic, plain bearings, not that it would matter?
Any wear on the other links look excessive?
That link is almost friction-less at low revs & wouldn't have mush stress at high revs from trying to rotate unless the lobe or roller or lifter bore is off.
How are those buttons retaining the link staked on?
Good luck.
Kind of my thinking as well.6.50camaro wrote: ↑Tue Oct 05, 2021 6:37 am Hard to tell in the photo put it almost looks like the button under the link bar in the pic pulled out (not staked in proper) and the other button failed as the first button started to work its way out of the lifter . Dan
Orientation of all of the lifters with the link bar lettering were all the same. One of those assembly details to pay attention to.

Sorry mag. I misread your post. I thought you were commenting on the poor housekeeping.
Really? This is the first I've heard about link-bar roller lifters having such a short lifespan.swampbuggy wrote: ↑Tue Oct 05, 2021 10:34 pm It does not matter who you buy from or how much you pay for it, if you run parts long enough they will fail. 35k miles on roller lifters is a Lot without a rebuild .

That in itself says something.
A photographic illusion. Here's the same set under different light.
