Odd crank cap bearing?
full grrove bearings, into the modern age just like the air cooled vw bug
the king bearings are alecular??? aluminium race bearings, which i belive are a bit harder and supposedly have better dimensional accuracy...??? who knows
hence they are full groove right round without a ware compromise
line up holes and put the other bits in as they fit
they are the only supplier for my motor since ACL went bust, been using a similar set for 10+ years no issues on my long bendy 7 main bearing crank
