Replacing pin holding landing leg beveled gear

I responded earlier to your post, when reading your last post I remembered how we would use large channel locks to get Spirol pins into the gears on our regulator drive gears. It would be like a press and you actually squeezed it into the hole. I would put a smaller pin into the hole from the opposite side and squeeze the smaller one out with the larger one. The smaller one is only used to line up the holes. Hammering on the pins too hard can do damage to the working mechanism. JMT
