Finally got the replacement green Viton o-rings. Pulled one through bolt at a time and replaced them. Took some pics of what I found. I used the same o-ring lubricant, the same techniques, and was just as careful to make sure that the chamfered washers didn’t turn.
Unlike the red Viton o-rings, the green o-rings did not squish out on the bolt head side when they were torqued…
I have no doubt that the green rings did deform as the torque squashed them flat, but I don’t think that they ‘exploded’ like the red ones.. I think that more of the green o-ring pushed its way into the bolt hole, where it belongs.
I can now see the value of having the remaining case holes chamfered. Next time!
