Is there a downfall in using the caged wrist pin bearings than the loose needle bearings? I am rebuilding a Johnson 150 60* V6 and loose needle bearings came out of the piston wrist pin but I now have the choice of going to caged or loose again, any suggestions?

I got the caged bearings by the way so hopefully all goes well and I don't see any downfall in using them and alot easier installing.

At 6000 rpm and less they work pretty much equally. In race motors we found the caged bearings to be stronger.

In this application with caged needle bearings, do we still use any washers on either end?
