S54 rebuild problems

[BMWfanz]

Hi guys! I'm rebuilding S54 with forged pistons and rods and today reveived rods from Pure Perfomance from Australia. There is one problem with locks for bearings, they are different from stock- like on this picture, any ideas how install it? I think in this case stoppers for bearings won't work and they can spun?
For example like on stock:

any ideas? sent it back?

Not sure but did you contact them and ask why the lack of locking bearings?

Contact the seller/manufacturer. Some race rods/bearings don't have any locating tangs at all.

I didn't received an answer from PPM, tried to find some rods with locks like that and found on vette LS series rods...have no idea how it works and not spun

[ForcedFirebird]

Tangs are to locate them, not to keep from spinning. The boundary layer of oil between the crank/bearing is what keeps them from spinning.

EDIT: Many stock mfgr's have double cuts, specially with modern broken cap design.

Some race rods/bearings don't have any locating tangs at all.

They aren't necessary if designed that way, however i have yet to see a production engine without them.

Today Pure Perfomance sent me a massage that all is ok and like ForcedFirebird said this is new type of noches and all will fit perfectly
