Rebuilding a 717 engine and brought another crank because the crank in the current engine has a bad rod end bearing.

I'm replacing the end bearings on the crank and notice that the PTO end bearings are not pinned, but are o-ringed. Should I use o-ringed bearings or use pinned bearing if the original crank in the engine came with pinned bearings.
