spiral or ring type piston pin retainers

[Rich Biebel]

Here is a joke that might fit for this...

Consider the new round wire pin locks "the green alternative "

In my experience if it says its "green" It just doesn't work worth a you know what....

Plenty of modern things are better and may take some getting used to.

Plenty are not and you regret getting sucked into the marketing...

I would assume a round wire lock would work fine in a properly machined groove with a pin finished the way it would need to be to work with that lock....and all proved by testing...

But exactly what is the reason to make a change from what has worked for decades.....

You have to ask yourself why did they make this change.....There is NO advantage or improvement since what they changed was not failing....
