Hollow dowel, tappet oil feed
Hollow crankcase dowel that also feeds oil to the tappets, PN 70-8751 (supersedes 70-1534/70-1534A).
This is a hollow dowel that sits in the crankcase and doubles as an oil feed passage for the tappets, part number 70-8751, also listed as E8751. It shows up in the crankcase and timing-gear figures across a long catalog run, from 1969 into the mid-1980s, which tells you it's a long-serving piece in the bottom end.

Being hollow, it's not just a locating pin - oil travels through it on its way up to the tappet area, so it's doing double duty holding things in register and keeping oil moving where it needs to go. It supersedes two earlier factory numbers, 70-1534 and 70-1534A, so if your parts book lists either of those older numbers you're looking at the same physical part under 70-8751 now.
Given how many catalog entries this one turns up in, it's clearly used in more than one spot or across more than one engine configuration - worth checking your parts book for your specific case, since some setups use one of these dowels and some use two.
