MAIN BEARING SET (4) 3CYL STD USA
Standard-size main bearing shell set (4 shells) for the triple-cylinder engine, USA spec.
70-6023 is a main bearing shell set for the triple-cylinder engine, standard size, sold as a set of four. The catalog notes USA spec, which points to the export version of these triples rather than the home-market build.

These shells sit under the crankshaft main journals and are part of what keeps the crank running true in the cases. Being a set of four means all the mains for the engine come together rather than piece by piece, which matters when you're rebuilding the bottom end and want everything at the same size and wear stage.
This is a standard-size set. If a rebuild has taken the journals undersize, there are oversize options in the same bearing family, but for a stock, unworn crank this is the one to reach for. Since we don't have a lot of catalog history on this specific line, it's worth a call to confirm exact application before you order.
