RE: tensioners again

["Sedon, Doug (OD/ORS)" <sedond@domain.elided>]

hi fred,

if i have it all wrong, then why is the zat "abortion" a, well er uh, an
abortion?  if the belts don't change size (ie - stretch), then why do they
*need* a tensioner that adjusts for temperature?  why do they need more tension
when cold?  i'm missing something here...

thanks,

doug s.

	Why is it that so few understand much about the tensioners that Alfa
sells?
	 To begin with, the belts DO NOT STRETCH!  They break first!  Both types
of
	tensioner (do not include the Zat abortion) actually compensate for
	temperature changes.  The hydraulic unit relaxes the tension while the
	engine runs but never enough to cause the belt to slip. (When properly
	adjusted) The newer mechanical unit does have bi-metalic spring to
handle
	temperature changes.  Notice the need to install at certain minimum
ambient
	temperatures?  Doug, you've got it all wrong! Fred
