I don't want to hammer them in at all, nor do I want to press them in, so I want to shrink the segmented bearings before inserting them. I think the loads from the piston pin are much higher than the cam bearings. Therefore I do not want to press in the segmented bearings .
I had contacted Anthony via Facebook, obviously he currently has no homepage via which I could reach him. Unfortunately, he did not answer.
I will build the tool to change the bushings.
Liquid nitrogen is unfortunately very expensive and not easy to get.
Does anyone have a link to Anthony's video?
Thanks. I already have the tooling ready for this job, if you want I can post some pictures to go with it.
Obviously he uses the segmented bushings. My question to him would have been in which orientation he install the segmented position. But I will see when my part delivery arrives, I have ordered new connecting rods as well.
If I understood correctly, he just puts the bushings in the fridge to shrink. Did I understand that correctly?

I go both ways. The bushings in the old rods are not segmented. I would prefer to install these. Apparently these are no longer available and only the segmented bushings are available. I have now ordered bushings AND rods to see which bushings are installed in the ordered rods. If it should be the segmented bushings, I then see at which point / orientation the segmentation sits.If you ordered new rods, they should come with the bushings installed. Are you going to remove the bushings from the new rods and put others in, or put new bushings in the old rods?

I have also worked on many engines, I had not seen anything like this before either.
This engine I had opened because of a catastrophic EGR cooler damage.
The only consolation for the truck owner is that there would have been problems with the engine at some point anyway due to the one-sided load and thus the chips/abrasion of the bearing shells (Currently, however, nothing of this was yet to be found in the oil/engine).
The question for me is what to do with an engine if I were to experience something like this again (the different values of piston protrusions and rod bearing shells worn on one side).
I don't think the big rebuilders pay attention to anything like this.
I made an interesting discovery today Jack. The piston pin bushings in the rods are also segmented on the original rods, you just see it very bad. If you press the bushings out of the rod, you can see the segmentation better on the outside.The OE rod I have here is similar to yours. Not a segmented bushing.
