How are hydraulic rollers ( retro link bar) supposed to be serviced with rivet in the way of the parts coming out?
Had three

collapse yesterday . I found three lifters with bent “C” clips.
The only way into lifter is to remove rivet.
Ya ya I know. Hydraulic lifter bad, but they are in my engine.

Thanks to all ,

That’s just how they are.

We had a 440 on the dyno last year.
Power was hanging on pretty good for the combo.
Tried sneaking the upper rpm limit from 5800 up to 6000.
Power was still not dropping off much at all.
Made a 2nd pull to 6k......... one plunger got stuck down at the bottom of the body...... and that was that.
Had to replace it.
 
3 lifters damaged in the same way? I would like to know the cause of the damage if you know. I think hydraulic lifters get blamed for problems caused by other sources. Maybe you lucked out with hydraulic lifters if they were solid you would have had no give and it seems the problem could have Been much more severe.
 
You will have to press out that rivet. Can you send those out to be rebuilt?
 
I was a dumb ***. I went from a solid flat tappet to the hydraulic roller over last winter.
All parts are Crane.
I forgot to lower MSD box from 7700 rpm to 6500.
I figure **** came apart at 7200 rpm.
I'm now going to stick a " $ " sticker to my right foot. :(:BangHead:
 
Drill it out and draw in another when your ready. Agreed, kinda lame design.

Who has these rivets?
They are hard as hell.
I used a grinder to remove rivet and washer. Then a punch to get remainder out.
Do any oem use link bars?
