No joke Luke,
Designing machinery is a complicated process that brings many engineering disciplines into play. Many other considerations are also included including repairability, operability, ergonomics, compatibility, commonality, market trends, and capital accounting just to lame a few.
I believe the fork uses two pins on the cross shaft, so rather than have a very robust clutch pedal attachment to the cross shaft such as a clamped spline, which would undoubtedly shear the two pins in the yoke necessitating splitting the tractor, the part that would most likely fail was designed to be on the outside of the clutch housing.
I have used Spirol pins to replace OEM pins in many different applications for years and have never had one fail.
I assume you replaced the yoke pins with Spirol too?

Bob, thanks for the welcome. I had some posts here Im sure of it but has been a long time… not sure why Im showing back from scratch…. no matter…
Still confused on the idea of the weaker link being outside so as to avoid having to split the tractor. My clutch fork pins broke which necessitated me splitting the tractor. The single hole on the clutch fork is pinned with a double 8×32 and 5×32 pairing. The same pin pairing is on the outside of the the bellhousing so I don't see how one set of pins would be less likely to fail than the other since they are the same set of pins inside and outside. (???)
I am only planning on replacing the clutch fork pin that broke. I'll leave the one on the outside and replace it with the stock one if it ever breaks. The way I see it, Ill have the likely-to-fail part on the outside
