Kingpin no crank hole

A search for "Kingpin" on the N Tractor Club forum/board didn't turn up any findings, & since this ground apparently has not previously been covered, I'll post a question.

IT shop manual for 8N tractors shows a starting-crank passing through hole in front kingpin to engage engine.

Since my tractor came without a crank, I thought it would be a fun project to build one of my own making, purchasing materials in kind, only to be astonished upon seeing front kingpin on 8N tractor has two bolts horizontally attaching the front king pin, but "nada" crank hole.

I am quite a bit puzzled, why there wouldn't previously exist a standard crank hole, as-manufactured by Ford?

Looking at below URL, you'll see what I'm talking about, clipped from IT shop manual:

Tractor's starter works fine & fires up easily, so cranking's non-requisite, however I have a Dearborn front end loader needing access through kingpin to engine for FEL's front-driven hydraulic pump.

It's no problem using drills/bi-metal hole saw/making necessary modifications allowing insertion of "homebrew" starting-crank through kingpin; Question: Is there something I'm overlooking which could cause issues post-modification?

Thanks in advance for any comments, ideas or suggestions :-)
