Bearing shells for ally rods
« on: January 29, 2019, 07:10:24 am »
Hi, Does anybody know who can supply drilled big end shells to suite ally rods. I have some Yoshimura rods and some Russ Collins stroker rods that need big end shells. Also can anyone tell me why the ally rods need the location pegs that make these shells with holes in necessary. (I have also had a set of Golden rods that required these).
I'm only old on the outside.

 There was obviously some concern with the shells spinning in the rods. You may have to make a jig and drill your own. 
If the things you own end up owning you, it's better to be owned by some cool things.

Thanks Don, I am surprised at that because they still use the locating tangs. But there must be a reason for it and yours sounds logical. My problem is it's a Yoshimura lightened crank (so no markings) and yoshimura rods (again no marking) so I need to try different size shells and plastigauge them to find the correct shells.

Yes.  Aftermarket aluminum rods are fitted with a dowel pin in the cap to be used with a drilled lower bearing. Spun bearings would happen on every pass without it, likely due to the growth of aluminum but the elasticity benefit it provides is worth it.
Due to large volume on the automotive racing end, lower bearings shells can be purchased off-the-rack pre-drilled and coated.
