Distributor gear pin

You are slightly deforming the edge of the pin hole, after the pin is installed, not the gear teeth. A center punch and small hammer are all that you need.

Distributor gear pin
Ya got new gear guess says have drill out hole larger to fit roll pin,even shaft as well so how to assure its straight? Any ya all done this? 394 restore fun stuff!

394 distributor gear
Hey olds fans just got new distributor gear says have to enlarge hole to fit roll pin anybody done this? Seems have to make sure drill straight? Thx heres some pix thx!

My Hosier translation: "Do you fine sirs have any recommendations on how to ensure I drill the gear and shaft of the distributor straight for the too-large pin that was provided for my 394 restoration?"
My counter-question to the OP is, why not try a pin of the proper size and avoid drilling anything?

The split roll pin that the "Olds Parts Guy " sold you is the cheap and easy way out! Those pins fail over time as they have no cushioning ability from the shock/strain loads put on the gear from the oil pump! What is the actual size of the hole in your gear and distributor? The later 330 to 455's use a 1/8" by 7/8" long coiled spring pin. May be the same for yours.
End ViewFor tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
All pins meet ASME specifications for material and dimensions. Metric pins also meet ISO 8748 specifications.
Steel pins offer good strength.
18-8 stainless steel pins resist corrosion better than 420 stainless steel pins. They may be mildly magnetic.
420 stainless steel pins resist wear as well as corrosion. They are magnetic. Those that are passivated offer added protection against corrosion and oxidation
