Yep. I misread what he wrote.

George,
Are you reading what Joe's writing? He's not using the mechanical
tensioner. He's using the same hydraulic setup that you're in favor
of.

My experience is exactly the opposite. I find the Canadian-made
mechanical de-tensioner to be utter garbage. I've had two of them
fail. One was caught before the belt jumped, the second one, alas,
was not. A much better solution, IMHO, is to use one of the original
Alfa hydraulic de-tensioners with the hydraulic line blocked off (if
you have a mechanical de-tensioner fitted, this has already been
done). It turns out that the hydraulic part of the original de-
tensioner is not needed. It works fine without it. The springs in
the mechanical de-tensioner, due to their clockspring design are
subject to popping-out sideways causing a failure. Also, I have
found that lots of mechanics don't understand how to install them
properly to get the proper tension in the first place. My advice is
to stay away.
